The United States Environmental Protection Agency has found alachlor to potentially cause the following health effects when people are exposed to it at levels above the maximum contaminant level (MCL) for relatively short periods of time: slight skin and eye irritation.
Alachlor has the potential to cause the following effects from a lifetime exposure at levels above the MCL: damage to liver, kidney, spleen; lining of nose and eyelids; cancer.[3]
If released to soil, alachlor can be broken down by bacteria and sunlight, usually within two months. However, alachor does not bind to most soils very well and may either evaporate or leach into ground water. Sunlight and bacterial action are also important for degrading alachlor in surface water, but evaporation generally does not occur. Once alachlor enters ground water, its break down is very slow. The biaccumulation of alachlor in aquatic organisms is not important. Any alachlor taken up by plants or animals is quickly eliminated.[3]
