Four general product classes--pesticides, paint products, household cleaners and automotive products--are reviewed in this document. Each product class is described, and several aspects of the problem associated with product use or disposal are examined, including estimates of volumes used and environmental impacts. Technical data on the specific chemicals which are most often found in these products are provided. This information, which includes sources, consumption figures, toxicity ratings, human health hazards, physical characteristics, environmental effects and disposal recommendations, is presented in lengthy tables at the end of each product section. The Appendices provide a simplified overview of organic chemistry as it applies to consumer products, and a discussion of toxicity and hazard--measurements of and differences between the two terms.
