摘要：
Synthetic hexachloroethane (HC) smoke combustion products are a complex mixture containing Zn, Cd, As, Pb, Al, CCl4, C2Cl4, C2Cl6, C6Cl6 and HCl. The dissolved components of the synthetic HC smoke combustion products mixture are quite toxic to a number of freshwater species, especially a green alga, rainbow trout and water flea. Acute 48‐h static bioassays were conducted with neonate Daphnia magna to assess the toxicity of various individual components and mixtures of components of the synthetic HC smoke combustion products mixture. These tests showed that the metals, zinc in particular, were the major toxic component of the mixture. When the chlorinated organics were tested as a group, they caused only minimal toxicity to the daphnids. Copyright © 1990 SETAC
