"This compilation will provide ready reference for potential toxicity of chemicals found in the workplace, and should be useful to occupational health physicians, industrial hygienists, toxicologists, and researchers." Alphabetical arrangement by substances. Entries include such details as molecular weight, Wiswesser Line Notation, synonyms, and reference from which data about toxicity derived. Miscellaneous appendixes, including one titled Aquatic toxicity. Bibliographic references.

Most Americans eat genetically modified food on a daily basis, but few of us are aware we’re eating something that has been altered. Meanwhile, consumers abroad refuse to buy our engineered crops; their groceries are labeled so that everyone knows if the contents have been modified. What’s going on here? Why does the U.S. government treat engineered foods so differently from the rest of the world? Eating in the Dark tells the story of how these new foods quietly entered America’s food supply. Kathleen Hart explores biotechnology’s real potential to enhance nutrition and cut farmers’ expenses. She also reveals the process by which American government agencies decided not to label genetically modified food, and not to require biotech companies to perform even basic safety tests on their products. Combining a balanced perspective with a sense of urgency, Eating in the Dark is a captivating and important story account of the science and politics propelling the genetic alteration of our food.

Takes stock of how natural resources (land & water) & commercial inputs (energy, nutrients, pesticides, & machinery) are used in the agricultural sector; shows how they contribute to environmental quality; & links use & quality to technological change, production management practices, & farm programs. Provides a comprehensive source of data & analysis on the factors that affect resource use & quality in American agriculture. Examines the economic factors that affect resource use, & estimates the costs & benefits (to farmers, consumers, & the government) of meeting conservation & environmental goals. Charts & tables.

In March, 1983 a workshop on Pollutants in Porous Media was hosted by the Institute of Soils and Water of the Agricultural Research Organi zation in Bet Dagan, Israel. At this workshop, the unsaturated zone be tween the soil surface and groundwater was the focal point of discus sions for scientists from various disciplines such as soil chemists, physicists, biologists and environmental engineers. Since then, the prob lem of soil and water pollution has only worsened as more and more cases of pollution caused by human activities including agriculture and industry have been revealed. A great deal of work has been carried out by environmental scientists since 1983 in elucidating the behavior of the many classes of pollutants and the complex physical, chemical, and bio logical transformations which they undergo as they move through the soil to the vadose zone and, in many cases, the groundwater. In light of this, it was felt that another meeting of specialists from the many disciplines which deal with this subject was necessary and so a Second International Workshop on the Behavior of Pollutants in Porous Media, sponsored by IUPAC (the International Union of Pure and Applied Chemistry) and IAHS (the International Association of Hydrological Sciences), was organized and held in the Institute of Soils and Water of the Agricultural Research Organization in Bet Dagan, Israel during 1987. June, The present volume is a selection of the talks presented at this second workshop and deals only with toxic organic chemicals in porous media.
