ABSTRACT
The effects of dissolved humic concentrations on the uptake and toxicity of cadmium using the freshwater oligochaete Lumbriculus variegatus as a sentinel monitor of environmental pollution were investigated. Acute static bioassays were performed and the data showed that both the uptake and lethality of cadmium decreaed with increasing humic acid concentrations. These results confirm that free cationic species correlate better than total dissolved metal concentration with cadmium bioavailability and toxicity...
