Validation status of QSAR models for exposure- and effects-related parameters

The exposure-related parameters of contaminants may be estimated with varying degrees of reliability (Table 6.1). 

Estimations of effects-related parameters are subject to varying degrees of uncertainty (Table 6.2) that depend on the inhomogeneity of the underlying experimental material. 

Only a few classes of specific toxicants diverse descriptors +
