Abstract:

A new formulation, Decontaminating Agent Multipurpose DAM decontamination Solution, is being considered as a replacement to the DS-2 decontaminating solution. The new formulation is composed of calcium hypochlorite and N-cyclohexyl-2-pyrrolidinone. Since this is a new formulation little environmental data exists. To estimate potential impact to an aquatic environment, Daphnia magna and Photobacterium phosphoreum a luminescent marine bacterium were exposed to the DAM solution and to the individual components Calcium hypochlorite and N-cyclohexyl-2-pyrrolidinone. The toxicity of the DAM solution to D. magna and P. phosphoreum was 5000 and 0.00053, respectively highly toxic. The toxicity of calcium hypochlorite and N-cyclohexyl-2- pyrrolidinone to daphnia was 0.04 mgL highly toxic and 107 mgL moderately toxic, respectively.
