Application of chlorinated hydrocarbons, dithiocarbamates, benzimidazene derivatives, phtalimides, organomercury and organotincompounds, halogenophenoles, nitrophenols, arsenates, fluorosilicates, and others in material finishing is almost entirely oriented to the intended purpose, and consequences for adjacent areas are not considered. Insufficient attention is paid to generation of biocide agents by abiotic and biotic processes in environment.
