1,2-Dichloroethane is toxic (especially by inhalation due to its high vapour pressure), highly flammable, and possibly carcinogenic. Its high solubility and 50-year half-life in anoxic aquifers make it a perennial pollutant and health risk that is very expensive to treat conventionally, requiring a method of bioremediation.
