Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
The concentration-response relationships of four species of earthworms are summarized for 62 chemicals and two tests protocols. A weibull function is used to summarize these data for each chemical in terms of sensivity and toxicity, in addition to the LC50.
