[Decomposition of simazine herbicide in algal cultures].

The possibility of simazine accumulation and detoxication in the cultures of some species of green, yellow-green, and blue-green algae was investigated. It has been shown that the algae can accumulate simazine in amounts hundred times exceeding its concentration in the cultural medium. The protein fraction contained up to 28.8% of simazine accumulated by the algae. The accumulation of water-soluble products of simazine metabolism in the cultural medium is indicative of the partial transformation of the herbicide.
