Effects of PCB (Aroclor 1254) and p,p DDT On Production And Survival of Daphnia magna Strauss

The combined and individual effects of p,p DDT and PCB on the survival and reproduction of Daphnia magna strauss in laboratory toxicity tests are described. Concentrations of DDT at 0.30 and 0.50 ppb increase the toxicity of Aroclor 1254 to Daphnia by as much as two times, and exposure to a no-effec...

Zusammenfassung:The combined and individual effects of p,p DDT and PCB on the survival and reproduction of Daphnia magna strauss in laboratory toxicity tests are described. Concentrations of DDT at 0.30 and 0.50 ppb increase the toxicity of Aroclor 1254 to Daphnia by as much as two times, and exposure to a no-effect concentration of 12 ppb PCB serves to increase the susceptibility of Daphnia to DDT by an average of 20%.
