(JP8309364-A)      Detoxifying biocide which is toxic to aquatic life comprises bringing it into contact with a water soluble organic thiol cpd. and opt. a base, for an effective period of time, in an amt. effective to detoxify the biocide.    Also claimed is a kit comprising an organic thiol in a plastic or plastic lined container, inert adsorbent, a spill pillow and a pair of gloves.    USE -   The method is used to detoxify industrial effluents contg. biocide, e.g. 5-chloro-2-methyl-4-isothiazolin-3-one, 2-methyl-4-isothazoin-3-one, 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one, 2-n-octyl-4-isothiazolin-3-one, benzisothiazolone, 2-methyl-4,5-trimethylene-4-isothiazolin-3-one, methylenebisthiocyanate, 2,2-dibromo-3-nitro-lopropion-amide, bromochloro-dimethylhydantoin, glutaraldehyde, hypobromous acid, hypochlorous acid, hypochlorite, 1,4-bis(bromoacetoxy)-2-butene, 4,5-dichloro-1,1-di-thia cyclopentene-3-one and 2-bromo-2-nitropropane-1,3-diol (all claimed).    ADVANTAGE -   The industrial waste is effectively detoxified in an environmentally safe and cost effective way.
