摘要: Abstract We used the WHAM chemical speciation model and WHAM-FTOX toxicity to analyse published results of laboratory experiments covering 52 different freshwater biological test species 24 metals, a total 2037 determinations EC50 with accompanying data on solution composition. The key extracted parameter was αM, in that characterises toxic potency metal basis its estimated metabolically active body burden. For 16 sets applying metal-test pairs appreciable variations composition, values back-calculated from averaged αM showed significantly (p
