Default Guideline Values (DGVs) For Toxicants When Assessing Water Quality
Default Guidelines Values (DGVs) are developed according to risk assessment principles by using data derived from laboratory tests in clean water. The species sensitivity distribution (SSD) method is used in deriving DGVs for toxicants during water quality assessment. In circumstances where SSD is not applicable, the assessment-factor approach is used. It provides the best estimate of toxicant ...
