Selected Issues in Risk Assessment

The National Research Council closes the landmark series Drinking Water and Health with Volume 9, published in two parts:Part I: DNA Adducts provides an overview of DNA adducts and their effects on human health, explores the techniques currently in use for detecting them, offers an outlook on future toxicity testing, and lists specific recommendations for action.Part II: Mixtures explores the issues surrounding multiple-chemical exposure from drinking water and reviews options for grouping compounds so their toxicity in mixtures can be reliably assessed. The book describes alternative approaches and considers the option of developing a modified "hazard index" for chemical compounds.
