Water covers about two-thirds of the surface of earth, but only 0.627 percent of this water is the sweet surface and subsurface water available for the survival of freshwater organisms including man (1,2).

Proceedings of the symposium on Environmental Biotechnology: Moving from the Flask to the Field held in Knoxville, Tennessee, October 17-19, 1990

This role springs from two key problems that face scientists and public agencies required to set acceptable exposure standards or to determine criteria for the toxicity of therapeutic chemicals: How do you evaluate effects that may show up only as subtle functional disturbances?

Based in part on the symposium on Biodegradation of Nitroaromatic Compounds held in Las Vegas, Nevada, May 22-23, 1994

As a consequence of this report, a position as science adviser to the secretary-general of NATO (later changed to Assistant Secretary General for Scientific and Environmental Affairs) and a science committee composed of one highly qualified scientist from each of the member countries of the Alliance was established in 1958.

Proceedings of the Eighth Annual Conference of the Air Resources Information Clearinghouse held in Washington, D.C., December 5-6, 1991

The purpose of the symposium "Environmental Dynamics of Pes ticides" was to explore the concept of chemodynamics as applied to pesticides and thus may help in developing the emerging field of environmental chemodynamics.

Based in part on the symposium on Biodegradation of Nitroaromatic Compounds held in Las Vegas, Nevada, May 22-23, 1994

Through the coupling of reliable biological detection systems with methods of chemical fractionation and analysis, it is frequently possible to isolate the individual chemical species that show biological activity.

The purpose of this publication is to report on a series of research workshops which examined the place of environmental perception in a comprehensive system of indices for assessing and monitoring trends in environmental quality.

Bloom, ed., March of Dimes Birth Defects Foundation, White Plains, New York, 1981) and "Indicators of genotoxic exposure in humans" (Banbury Report 13, B.

For instance, whereas we have a great deal of data on residues in North America, we know virtually nothing about the extent of pesticide contamination in Africa, South America and much of Asia, although large amounts of organochlorine insecticides have been used in these areas.

Increasing international concern is being expressed regarding the contamination of the environment with polychlorinated dibenzo-p dioxins (PCDDs) and polychlorinated dibenzofurans because certain of these chemicals have been shown to be highly toxic to animals and are ubiquitous in the environment.
