Toxic effects of zinc acetate and lead acetate on anisms
[Abstract] In recent years, with the rapid development of economy in coastal areas, industrial wastewater discharged into the ocean large, serious pollution to the marine environment, which did harm to the coastal aquaculture industry. Heavy metal ions, especially Pb, Zn, Cd pollution is a major reason caused the death of marine biological poisoning. Lead acetate, zinc acetate for the clams in the median lethal concentration within 96 h were ,,,;,,,. And lead acetate, zinc acetate within 96 h of snails and half lethal concentration were ,,,;,,,. Lead acetate concentration on the safety of the clams and snails were mg/L, mg/L; Zinc acetate concentration on the safety of the clams and snails were mg/L, mg/L.
