  • To provide basic toxicity data for formulating risk characterization benchmarks, the effects of tungsten on survival, growth, and reproduction were investigated in the earthworm Eisenia fetida. Parallel studies with lead as a reference toxicant also were conducted. Although sodium tungstate (Na2WO4) was less acutely toxic than lead nitrate (Pb(NO3)2) in 14-d spiked field soil acute toxicity assays (lethal concentrations for 50% of organisms: W, 6,250 mg/kg; Pb, 2,490 mg/kg), tungstate… CONTINUE READING
