Popis: | The alga, Ankistrodesmus spiralis, becomes saturated with photodieldrin in 8 hours. The Daphnia whether contaminated by feeding on the algae saturated with photodieldrin or by directly absorbing this insecticide eliminate about 50 per cent of the absorbed photodieldrin in 4 days which increases up to 70 per cent in 7 days. However, continuous exposure of daphnids to photodieldrin results in increased absorption and accumulation of this insecticide. Transfer of the goldfish contaminated with photodieldrin to clean water results in initial elimination in 24 hours whose rate in is then is then subsequently reduced. These two organisms are thus capable of eliminating their body residues of photodieldrin, the "terminal residue: of dieldrin, if their environment is decontaminated. |
