Applying the terrestrial biotic ligand model (TBLM) to species sensitivity distributions

摘要：

We have applied the recently developed Terrestrial Biotic Ligand Model (TBLM) to develop species sensitivity distributions for copper and nickel for terrestrial organisms. The TBLM approach allows us to evaluate the effect of key soil parameters on toxicity. The toxicity of Cu and Ni to six biological endpoints (barley root elongation, tomato shoot yield, spring tail juvenile production, red worm cocoon production, glucose induced respiration, potential nitrification rate) previously used to develop the TBLM are considered to elucidate the effects of the soil pore water chemistry on the relative sensitivities of these effects. The relative sensitivity of the endpoints changes significantly with respect to only pH for Cu toxicity and with respect to pH, pCa, and pMg for Ni toxicity, indicating that approaches which fail to account for these effects in deriving soil metal criteria are incorrect and may result in inadequate criteria.
