magnesium chloride ice melt environmental impact
Its that time of year again to start making the switch from winter to spring! At a water temperature of 2C decomposition took 100 days (Horner, 1992). It will melt ice to temperatures of -25F. Some sources I found group this with the salts. There are a wide range of ice melt products available on the market including Magnesium Chloride, Sodium Chloride, Brine Solutions, and Rock Salt, but do you know the environmental effects of each? Lowest melting point: Will vary. This is because runoff containing these materials can flow directly into natural waterways without being treated first. One study showed that about half of the birds found dead in a particular area were killed by contact with ice melt chemicals. The effect of chloride on plants has been seen at distances of100 to 650 feet off the road (Fischel, 2001). 50-lb Natural Sodium Chloride Sprayed with Magnesium Chloride Ice Melt Salt. The few complaints from motorists often involve cosmetic corrosion to aluminum parts due to liquid MgCl2. PCC Pavement Deterioration and Expansive Mineral Growth. Although some animal species are more affected by ice melter chemicals than others, all animals are susceptible to damage from chemical deicers. Most ice melt products, with their calcium chloride additives, will melt ice effectively in temperatures as cold as -10 F. Ice Melt and Rock Salt Pros and Cons While more expensive, some ice melt products are eco-friendly and better . Deicers reach the soil via runoff, splashing, spraying, or plowing. Model # 40B-BP-18PL. The oxygen consumption can lead to anoxic conditions in the soil, groundwater, or surface water (Fischel, 2001). Calcium Chloride vs. Magnesium Chloride 1. The following section separately describes the environmental effects of anions (i.e. Other effects (e.g. Most ice melts are blends of the same ingredients: sodium chloride, calcium chloride, or magnesium chloride. Rock salt, calcium chloride, potassium chloride, and magnesium chloride are naturally occurring salts. Many states have begun requiring that ice melter chemicals be disposed of in a landfill after use. CMA and Mg-acetate produces the most deleterious effects on concrete, with Ca-acetate being much less severe. At colder temperatures, the rate of decomposition will decrease and there will be an increased potential for the inhibitors to reach the groundwater (Cheng and Guthrie, 1998). . Denis Plouffe, also from the MTQ, had similar experiences. Table summarizing of properties of deicing agents. With the addition of beet juice, the arboretum is using nine times less salt, and saving an estimated $14,000 in material costs (The Morton Arboretum, 2014). Safe If Ingested Safe Thaw crystal leaches out a deicing liquid to speed up the melting process even in subzero temperatures Will cover 100 square feet per pound Safe Ice Melts for Concrete + What Products to Avoid The chloride-based deicers discussed in this section are sodium chloride (NaCl), magnesium chloride (MgCl2), and calcium chloride (CaCl2). By February of 2014, 1.5 million gallons of Beet Heet had been sold. It's also not irritating when it comes in contact with skin. 1999-2023 Grist Magazine, Inc. All rights reserved. While no ice melt is "safe" for pets, the ASPCA says this product's primary ingredient, magnesium chloride, can be less dangerous to pet paws than other materials used in ice melts, but it can still cause them to become sick if they ingest it while trying to lick the substance off their paws. There is an ice melter out there called magnesium chloride hexahydrate. It was suggested that Caliber M1000 and Caliber M2000 should not be heavily used without strict guidelines and further testing, as both products exceeded environmental background concentrations of phosphorus and ammonia and both contained large quantities of contaminants, while traditional magnesium chloride was approved (Lewis, 2001). A small percentage of the total applied chloride is evidenced to be transported by air. It is through a combination of using deicing alternatives and managing snow melt runoff. Chloride entering groundwater systems is likely to persist for a long time since there is no significant removal mechanism and groundwater moves slowly. Yes, Ice melt can be terrible for the environment. People can come into contact with these chemicals through dermal exposure, inhalation of the particles, and ingestion. Chloride transported by air can affect soil and surface/groundwater, but deposition on the vegetation is the primary concern (Levelton Consultants Ltd., 2008). Magnesium Chloride. 17.12.2015. The only newsroom focused on exploring solutions at the intersection of climate and justice. CMA tends to leave a slush, which may be undesirable for sidewalks or driveways. Other chemicals that have been found at trace levels in deicers are arsenic, lead, and mercury (Dindorf, 2008). While these are typically safer ingredients, they may also cause stomach upset. Another unconventional additive that has been used is cheese brine. Salt can be used as an alternative but is harmful to the environment. Chloride in deicer solutions promotes decalcification of paste and alters ettringite to chloroaluminate. (Products intended to provide traction, instead of melting ice or snow, include sand, gravel, kitty litter, and wood ash.) Several different types of deicing chemicals exist. Some products are also available which contain ingredients that prevent snow and ice formation. This method can easily result in runoff, which can affect nearby areas and waterways. It works well on most surfaces though it is not ideal for fresh concrete surfaces or concrete that has not been sealed properly and is environment . Field Handbook for Snowplow Operators, Minnesota Local Road Research Board, 2005-01. The SMCL is based on aesthetic concerns, specifically taste. Care should be taken when determining which chemicals are best for the intended application and for the environment surrounding the application area. The replacement of Ca(OH)2 with Mg(OH)2 will also reduce the pH of the pore solution [pH =12.6 for saturated Ca(OH)2 and pH = 9.0 for saturated Mg(OH)2] which, if occurring at the rebar level, will result in the loss of passivation of the steel and allow the onset of active corrosion, even in the absence of chloride ions (164). The Material Safety Data Sheet for magnesium chloride lists many harmful effects including: Eye irritation and burn from contact Skin irritation and burn (including in the mouth and throat) when touched or ingested Gastrointestinal irritation with nausea, vomiting and diarrhoea when ingested Respiratory irritation when MgCl2 dust is inhaled This effect, combined with the presence of chloride ions, will further accelerate the corrosion of the rebar. The symptoms associated with salt impacts are similar to those of a drought; stunted growth, brown and falling leaves/needles, dying limbs, and premature plant depths (National Research Council, 1991). Ice melt products are bad for the environment, as they increase the risk of flooding and sea-level rise. Sodium, magnesium, and chloride in surface and groundwater can affect the hardness of water. A laboratory investigation using concrete samples obtained from existing Iowa highways suggest that magnesium and calcium deicers may accelerate highway concrete deterioration (Cody et al., 1996). If theres no ingredient list on the package, dont buy the stuff.

Magnesium chloride is a very similar product and becoming more popular. This pet-safe brand relies on magnesium chloride too, and includes urea, a fertilizer component whose use in deicers is controversial: it works, yes, but is damaging to waterways. References to Reports/Studies References to Reports/Studies Top Handbook of Chemistry and Physics, Chemical Rubber Company McElroy, AD, CC Chappelow, G Cooper and JA Gall. http://www.ctre.iastate.edu/pubs/semisesq/session1/cody/. It works faster than rock salt and is effective down to -15 degrees Fahrenheit. With 1/3 less chlorides, it is safer for pets, people, and environment. Source: www.walmart.com. The distribution of the deicer is a complex process, an overview of which is provided in the figure to the right. At high concentrations, CaCl2, MgCl2, and CMA cause significant changes in concrete that result in loss of material and a reduction in stiffness and strength. When any ice melt product is applied to a road surface, it is inevitable that some of the product will end up as runoff, flowing into plants, greenery, or bodies of water. Degradation of the acetate ion consumes oxygen, which is one of the biggest environmental concerns associated with the use of acetate-based deicers. This is especially dangerous because it allows for quick entry of chemicals into the environment without allowing time for them to dissipate or evaporate first. In addition to purchasing an ice melt product that is safer for the environment, it is also important to only use the required amount of the product for your job size. Ice melt is less corrosive than rock salt but can be equally destructive if not used correctly. Helmy et al. Iowa DOT final report HR-384, Concrete Deterioration and Expansive mineral Growth. In the Horner (1988) study, the test sites that received an addition of CMA were found to have an increase in permeability up to 20 times more than that of the control plots. We can always try using natural ice melting materials instead like hot water or steams. As part of our commitment to sustainability, in 2021 Grist moved its office headquarters to the Bullitt Center in Seattles vibrant Capitol Hill neighborhood. Do not mix chemical products with fertilizers, pesticides, or other chemicals without checking the label first. Samples were experimentally deteriorated using wet-dry, freeze-thaw, and continuous soak conditions in solutions of magnesium chloride, calcium chloride, sodium chloride, magnesium acetate, magnesium nitrate, and distilled water. The exact proportions of these chemicals varies by product brand. Calcium Chloride, Magnesium Chloride and Acetate deicers all have moderate to low impact. Similar observations were made by Wakeley et al. The chloride in road salt flows into our lakes, streams, and groundwater, potentially harming our environment. An international team of scientists observed that adjoining ice shelves play a role in inflicting. This page was last edited on 23 November 2022, at 15:05. Magnesium chloride de-icing products are less corrosive than their calcium chloride counterparts, yet they're dangerous for animal life and wildlife. The salts in ice melt come in pellet form, but it doesn't provide the traction rock salt offers. Sand and gravel aquifers in the TCMA had chloride concentrations that ranged from less than 1 milligrams per liter to 8,900 milligrams per liter, with a median concentration of 86 mg/L. Web hazards of magnesium chloride. If you must use it, avoid sodium chloride. In fact, there is no perfect ice melt out there so the best step on this slippery topic may be to avoid the stuff altogether. No pet safe deicing pellet claims to be safer (easier to use, more effective, or cheaper to use) than Liquid PlaySAFE Each drop works to -15F. Be careful not to overuse this method as you do not want to affect water quality. Human health is also affected by chemical ice melter. Small ponds and slow streams are estimated to be most impacted by deicers because the likelihood of dilution and dispersion is lower in those environments (Fischel, 2001). 40-lb Natural Sodium Chloride Ice Melt (1008-Count) Granules. The samples were immersed in 4-percent solutions that were renewed every month. All concrete types contained dolomitic limestone aggregates, because it is commonthroughout the State of Iowa. Model # 50B-CLEAN. At lowconcentrations, MgCl2 and CMA can cause measurable damage to concrete. Snow & Ice Salt & Chemicals Unlimited, LLC is a leading supplier of ice melt, decier, dust control, and snow removal tools and equipment with locations in Ijamsville and Silver Spring, Maryland. chloride) and cations (i.e. Ice melt also contains sodium chloride, along with other chemicals like calcium chloride and magnesium chloride. Safe to use around plants, pets, and children; Ice melt won't damage concrete and is environmentally safe for land and waterways. Stay tuned for our spring products! The Scotwood Industries Road Runner Ice Melter uses a combination of 3 chemicals: Calcium Chloride, Magnesium Chloride, and Sodium Chloride in its pellets, which makes this deicer very effective at melting snow and ice up to -15F below zero.. 1 "They're all salts," says David P. Orr, director and senior engineer of the . The applied salt dissolves into 40% sodium ions (Na+) and 60% chloride ions (Cl-) in the melting snow and ice and make their way into our environment. There is uncertainty about CMA causing the release of metals from soil (Amrhein et al., 1992; Horner, 1992; Granato et al., 1995; Levelton Consultants Ltd., 2008; McFarland and OReilly, 1992). Mineral salts, calcium chloride, and potassium chloride can be dangerous to humans. See Related: Important Pros and Cons of Biofuels to Know. If excess salt is used, the most visible impact will be noticeable in grass, shrubs and . How Ice Melters Affect the Environment Much of the concern related to the environmental impact of ice melters is in regard to chloride contamination of water and soil. MAGNESIUM CHLORIDE Performance on Snow and Ice Claim: Both materials effectively melt ice and snow to -32C (-25F) FACT:Calcium chloride works well down to this temperature, while the melting action is impractically slow at this point. Earth Friendly Products Ice Melt Eco-claims: Safe for pets and vegetation Active ingredients: Magnesium chloride hexahydrate, calcium chloride (2-3%), potassium chloride (0.5-1%), sodium chloride (0.5-1%) Price paid: $12/6.5 lbs. Cyanide is harmful to the environment if it is leached into groundwater or carried to surface water. Magnesium Chloride Ice Melt It is slow acting and more expensive than some of the other ice melt products. Facebook, Follow us on 1999-2023 Grist Magazine, Inc. All rights reserved. Put down plastic or wax paper (before applying the chemical) to catch any excess chemicals on your shovel or mop. Magnesium chloride (MgCl 2 )is considered to be safer than NaCl but requires twice the amount to cover the same area, making it more expensive. Paws Applause Ice Melt n Traction Crystals Eco-claims: Paws down, the pet-friendliest ice-melt formula Active ingredients: Magnesium chloride hexahydrate, urea, Dolomitic limestone Price paid: $15.32/20 lbs. Although there is some disagreement about deterioration of the cement paste, there is consensus that magnesium readily reacts with the various cement phases. Ice melt has its pros and cons. If theres one lesson I took from that story, its this: Man, the 50s were a different time, werent they? Your support keeps our unbiased, nonprofit news free. minimizing the impact on the environment and reducing the risk of any subterranean corrosion. As is the case with food and beauty products, the ice-melt industry has cottoned on to the fact that people want green. They are exposed to all of the above magnesium chloride side effects by walking in a salted area. And it works fast. Road Runner. An increase in permeability was noted. Salt and sand are the most common and least expensive materials for de-icing outdoor surfaces. The only newsroom focused on exploring solutions at the intersection of climate and justice. All of these products can be bad for the environment. The beet juice additive has minimal environmental affects, and helps the salt stick where applied. Inferno Ice Melter Eco-claims: Melt the ice protect your landscape Active ingredients: Calcium magnesium acetate, potassium acetate, pure sea sodium, urea Price paid: $19.90/50 lbs. These solutions have low electrical resistivity (i.e., they can readily conduct electrical current through solution) and, when they coat insulators, can allow transfer of current around the insulator to a greater degree than without salts. Read the ingredients, not the claims. In bedrock aquifers, chloride concentrations ranged from less than 0.5 milligrams per liter to 680 milligrams per liter, but in general did not exceed the secondary SMCL of 250 milligrams per liter. Many of our clients have experienced similar problems with magnesium and calcium. Of the three I tested, it was slowest to take effect, although it eventually did the job. People can also store leftover chemicals in airtight containers until they are ready to be used again or disposed of in a landfill. A basis description of the mechanism is as follows (214): High ionic salt solutions can exacerbate the process. The hardness of water will be reduced if there are elevated levels of sodium and will be increased if there are elevated levels of calcium and magnesium (Cheng and Guthrie, 1998). But magnesium chloride dissolves when there is only about 20 to 30 percent humidity. Specimens exposed to NaCl had higher compressive strength values than those exposed toMgCl2, even higher than those exposed to freshwater after 12 months of exposure. However, they do have a negative environmental impact. One of ours is salting the plants. That refers to the time my mother, a high-school student prone to merry pranks, snuck in to her school dining hall at night and, well, salted the plants. The degree of aerial deposition plays a defining role in whether or not effects occur.Major multi-lane and high-speed highway traffic can aerially disperse salt aerosols quite extensively. Selecting a salt to melt ice depends on its cost, availability, environmental impact, toxicity, and reactivity, in addition to its optimal temperature. While municipalities study the best approach (and test creative alternatives), homeowners are left to their own devices. It is corrosive to metal and can be damaging to vegetation if over-applied. Coffee grounds work like sand and provide excellent traction on slippery surfaces. It is sometimes used as an alternative to chemical ice melts because it doesnt contain any harmful chemicals. These cores were exposed in the laboratory to various salts and subjected to repeated freezing and thawing cycles. The three products were examined in terms of main ingredients, corrosion inhibitors, and contaminants. Just be sure to shovel away any excess water after pouring, as it can refreeze and form new ice if left standing. There are some upsides to using deicers. Known as one of the greenest commercial buildings in the world, since it opened its doors on Earth Day in 2013 the Bullitt Center has been setting a new standard for sustainable design. The Snow Joe AZ-25-EB Melt-2-Go has made our list as the best value ice melt. Kelsey and Hootman (1992) found that sodium chloride was detected at a height of 49 feet (15 meters) within 220 feet (67 meters) of the highway. Skin contact with these products is also dangerous because they can cause problems such as dermatitis or irritation. Magnesium chloride is exothermic (releases heat), and is effective in colder temperatures. Much chemical ice melts causes runoff, which contaminates nearby waterways and ecosystems. It will melt ice to temperatures of -25 degrees F. It gives off heat as it dissolves which melts the ice quicker but leaves a slimy residue. Features MAG out-performs other ice melters It melts ice effectively at temperatures as low as -13F (-25C), which is considerably below most other products. In North America it is used regularly in northern states and . The presence of chloride, magnesium, and calcium may also result in the mobilization of heavy metals sorbed to soil particles (Amrhein, and Strong, 1990; Backstrom et al., 2003). See Related: How to Make Home More Energy Efficient? The salt will reach the skin on their paws. It is not known at what rate Mg(OH)2 will replace Ca(OH)2, specifically at the rebar level. Magnesium chloride is used for low-temperature de-icing of highways, sidewalks, and parking lots.When highways are treacherous due to icy conditions, magnesium chloride is applied to help prevent ice from bonding to the pavement, allowing snow plows to clear treated roads more efficiently.. For the purpose of preventing ice from forming on pavement, magnesium chloride is applied in three ways . Alone carbohydrates do not aid in melting ice or snow; however, their use can help reduce the freezing point of ice further than salt and can help salt stick better to the road surface (Fortin et al, 2014; Rhodan and Sanburn, 2014). This material is extremely corrosive, causing damage to plant and vegetable life, and greatly accelerating the destruction of most metals, primarily automobiles and their accessories. Conversely, Rechenberg and Sylla (166) found that formation of Mg(OH)2 at the concrete surface acts as a protective layer, preventing the ingress of aggressive species. Chloride is naturally present in Minnesota due to weathering of geologic materials. The level of chloride that must be reached before the plant is harmed depends on the type of vegetation. The toxicity and environmental effects of corrosion inhibitors vary greatly and are dependent on the composition (Pilgrim, 2013). The cation components of chloride-based deicers (i.e. Other traditional forms of de-icers aren't capable of melting ice at this temperature. environment and do not pose a threat to aquatic life, Important Pros and Cons of Biofuels to Know, 7 Best Solar-Powered Laptops to Buy Today, 9 Best Solar-Powered Computers to Buy Today, 10 Impactful Ways to Conserve Coral Reefs, Provide adequate ventilation when applying deicer chemicals. Magnesium Chloride is a hygroscopic salt, meaning it absorbs moisture from the air to lower the freezing temperature of water. Carbohydrate-based deicers are often made from the fermentation of grains or the processing of sugars such as cane or beet sugar (Rubin et al., 2010). Sodium chloride is also dangerous for animals and aquatic life such as fish and algae. BEST FOR PETS: Natural Rapport The Only Pet-Safe Ice Melt You Need. For magnesium . This is not recommended because sweeping ice melt into drains will allow it to flow directly into waterways. Long-term accumulation of chloride can result in reduced soil permeability and fertility, as well as increased soil alkalinity and density. The magnesium chloride will easily melt into a bring and begin to break down the ice. Magnesium chloride is a flakey compound that is clear to off-white. BEST FOR ASPHALT: Harris Pet-Friendly Ice-and-Snow Safe Melt. Magnesium chloride is a naturally occurring compound mostly found in seawater. Adapted from Local Road Research Board, 2012, Ketcham et al., 1996 and Levelton Consultants Ltd., 2008. Both magnesium and calcium salts were found to severely damage the concrete samples while plain NaCl was the least harmful. Earth Friendly Products Ice Melt Eco-claims: Safe for pets and vegetation Active ingredients: Magnesium chloride hexahydrate, calcium chloride (2-3%), potassium chloride (0.5-1%),. OPEN 24/7 BEFORE, DURING, AND AFTER EVERY STORM. Reader support helps sustain our work. What is the Environmental Impact of Fracking? See Related: How To Be An Environmentalist? Instagram, Follow us on We are open 24/7 before, during and after every snow and ice storm. They are primarily composed of salt or some other chemical that lowers the freezing point of water, preventing it from turning into ice on contact. When used as an anti-icing material, the organic material performed 30% better. Performance on Snow and Ice - 2. Chemical deicers can damage vegetation and corrode materials such as metal and concrete while posing a threat to wildlife and aquatic life. Kroening and Ferrey (2013) reported on the conditions of Minnesotas groundwater from 2007 to 2011. If you need to apply an ice melt fast and you find yourself without any products, a homemade solution can help in the short term while also being better for the environment and your outdoor space. See Related: Climate Change Quotes That Will Surprise You. Do you really need to melt the ice, or can you just make it walkable? SISCU offers premium ice melt products that are environmentally conscious while also remaining effective at minimizing dangerous ice buildup. How Ice Melters Work Generally, all ice melters work in the same way. 2023 by Minnesota Pollution Control Agency Another concern is that acetate-based deicers consume oxygen when degrading. Ice Melt vs. Salt Pros and Cons Dotting the I's. Rock salt melts existing ice and snow, whereas ice melt prevents ice and snow from forming. Damp conditions bring moisture, allowing the pollutants on the insulators to become slightly conductive. Blends often combine sodium chloride (in the form of rock salt or solar salt, a purer form of rock salt used in the higher quality blends) with a more expensive ice melt such as Calcium chloride or Magnesium chloride. The decay of the alternative additives in the environment will contribute to BOD (most specifically for the organic additives). Chloride concentrations were highest in shallow groundwater, typically at depths of 30 feet or less below the ground surface. As long as you only use minimal product and apply it intentionally, you will minimize environmental damage. Such reaction degrades concrete strength, and reduces the pore solution pH as well. Winter maintenance chemicals may chemically react with cement paste or aggregates and cause degradation of the concrete matrix. Chemical ice melts have a large impact on the environment, both directly and indirectly. Sometimes traction is enough. Compared with sodium chloride, magnesium chloride (MgCl2) and calcium chloride (CaCl2) may cause similar effects to vegetation such as growth inhibition, scorched leaves, or even plant death (TRB, 1991; Public Sector Consultants, 1993; Cheng and Guthrie, 1998). It can become very slippery and cause crashes. They can improve soil structure; increase permeability; potential for metals mobilization. This article summarizes environmental effects of de-icing chemicals. Despite high mass loading, runoff and receiving water are predicted to dilute the concentration. It is also hazardous to animal life and can be dangerous for groundwater. Several years ago, in light of the wealth of scientific information on the damaging effects of magnesium chloride, Eco Solutions eliminated all usage of the the de-icing chemical magnesium chloride in our formulations. . The hydroscopic chlorides are more corrosive because deposits remain moist and allow corrosion to occur for a much longer period. However, this method does not provide the level of effectiveness that ice melts chemicals do. Magnesium Chloride Ice Melt Magnesium Chloride is good for the environment. 46. Electrical power is most commonly distributed by wires suspended on poles or towers. The mineral also can act as an early-stage plant nutrient for wheat crops. . Extreme cases include power lines directly next to elevated roadways such as alongside an overpass or bridge. Find My Store. Current leaks across the insulator and can cause line current losses, shorting, or heating and potential fire of. Experiments assessing the effects of magnesium products on concrete durability have shown that MgCl2 acts differently than magnesium sulfate (MgSO4) in that MgCl2 causes the cement pore structure to open whereas MgSO4 causes a densification (144). These products typically come in solid form and are used to keep sidewalks and other walkways free of snow and ice during the winter months. Magnesium chloride Is a corrosive liquid that can damage vegetation and corrode concrete, metal, and other materials such as plastics. It is important to be familiar with the ideal conditions for each ice melt product as you make your decision on which is best to keep roadway surfaces safe in your area. Potassium acetate/Acetic Acid (Pot Ac) or Sodium formate/Formic Acid (Sofo). Ice-melting chemicals commonly contain sodium chloride or rock salt, calcium chloride, potassium chloride, magnesium chloride, and/or urea, also known as carbonyl diamide. It degrades the quality of soil in the area where its stored or used. Several researchers agree that MgCl2 causes more severe deterioration to concrete than do NaCl or CaCl2, because of the reaction of Mg2+ with components of the cement paste (138, 145, 159163). Ingestion of these minerals can cause a varying degree of symptoms and health issues. Limestone aggregates, because it is through a combination of using deicing alternatives and snow.
