No, the chloride content of a liquid material is determined by the concentration of the solution and the molecular weight of the salt. Although magnesium chloride is commercially available in 30% solutions, it has a similar chloride content to a 35% calcium chloride solution. Research has shown that the impact of magnesium chloride is no less than other chlorides. The application rate of the product is also important in determining environmental impact. While magnesium chloride is often used for dust control, LIQUIDOW, which is a calcium chloride product, is typically applied at higher concentrations and may require less material to achieve the same result. Environment Canada recommends an application rate of 1.4 to 2.3 liters per square meter of magnesium chloride to achieve the same dust suppression capability as calcium chloride applied at a rate of 0.9 to 1.6 liters per square meter. The USDA Forest Service found that a magnesium chloride application rate of 0.30 to 0.50 gallons per square yard was necessary to achieve the same dust suppression performance as 0.20 to 0.35 gallons per square yard of calcium chloride.
