(Also known as: alpha,gamma-dichlorohydrin; 1,3-DCP; ACH) |
SUMMARY |
Alpha-chlorohydrin is a rodenticide that is not generally approved for use in the developed world. It has high potential for bio-concentration, moderately toxic to mammals, an eye irritant and a neurotoxin. Alpha-chlorohydrin is highly soluble in water and volatile but there is little environmental fate data available. It is highly toxic to birds but less toxic to fish. |
