| environmental impact statement | (EIS; FEIS) A statement of the environmental effects of a proposed action and of alternative actions. Section 102 of the National Environmental Policy Act (NEPA) requires an EIS for all major federal actions. (05 Dec 1998) |
|---|---|
| environmental medicine | Medical specialty concerned with environmental factors that may impinge upon human disease, and development of methods for the detection, prevention, and control of environmentally related disease. (12 Dec 1998) |
| environmental microbiology | The study of microorganisms living in a variety of environments (air, soil, water, etc.) and their pathogenic relationship to other organisms including man. (12 Dec 1998) |
| environmental monitoring | The monitoring of the level of toxicants, pollutants, or other harmful chemicals in the environment or workplace by measuring the amounts of these toxicants in the bodies of people and animals in that environment, among other methods. It also includes the measurement of environmental exposure. Humans and animals are used as indicators of toxic levels of undesirable chemicals. (12 Dec 1998) |
| environmental output | Environmental outputs are the desired or anticipated measurable products or results of restoration measures and plans. (09 Oct 1997) |
| environmental pollutants | Substances which pollute the environment. Use for environmental pollutants in general or for which there is no specific heading. (12 Dec 1998) |
| environmental pollutants, noxae, and pesticides | Substances capable of producing a harmful or deadly effect on living organisms as well as the environment. (12 Dec 1998) |
| environmental protection agency | <organisation> The U.S. Regulatory agency for biotechnology of microbes. The major lawsunder which the agency has regulatory powers are the Federal Insecticide, Fungicide, and Rodenticide act (FIFRA), and the Toxic Substances ControlAct (TSCA). (30 Mar 1998) |
| environmental psychology | The study and application by behavioural scientists and architects of how changes in physical space and related physical stimuli impact upon the behaviour of individuals. See: personal space. (05 Mar 2000) |
| environmental quality objective | This is a regulatory value defining the quality to be aimed for in a particular aspect of the environment. Unlike an environmental quality standard, an EQO is not usually expressed in quantitative terms and cannot be enforced legally. (09 Oct 1997) |
| environmental quality standard | This regulatory value defines the maximum concentration of a potentially toxic substance which can be allowed in an environmental compartment, usually air (air quality standard - AQS) or water, over a defined period. (09 Oct 1997) |
| environmental tobacco smoke | A complex mixture of chemical constituents and particulates released into the atmosphere from the burning tip of a cigarette, pipe or cigar or from smoke exhaled by the smoker. (09 Oct 1997) |
| environmental variance | Within a population, the measure of how much of the variation of a particular phenotype is due to environmental factors (as opposed to variations in genotype. An example might be the height of a human as determined by such factors as nutrition or infectious diseases during childhood. See: genetic variance. (09 Oct 1997) |
| united states environmental protection agency | An agency in the executive branch which endeavors to abate and control pollution in the areas of air, water, solid waste, noise, radiation, and toxic substances. (12 Dec 1998) |
| bright field microscopy | <technique> Optical microscopy, in which absorption to a great extent and diffraction to a minor extent give rise to the image, as opposed to phase contrast or interference methods of microscopy. (18 Nov 1997) |
