Solid Waste
Garbage, refuse, or sludge, or other discarded materials from a wastewater treatment plant, water supply treatment plant, and air pollution control facility that include solid, semi-solid, or contained material. It does not include materials dissolved in domestic sewage, irrigation return flows, or industrial discharges.
Refuse Disposal
Waste Management
Disposal, processing, controlling, recycling, and reusing the solid, liquid, and gaseous wastes of plants, animals, humans, and other organisms. It includes control within a closed ecological system to maintain a habitable environment.
Incineration
Waste Products
Industrial Waste
Medical Waste
Medical Waste Disposal
Management, removal, and elimination of biologic, infectious, pathologic, and dental waste. The concept includes blood, mucus, tissue removed at surgery or autopsy, soiled surgical dressings, and other materials requiring special control and handling. Disposal may take place where the waste is generated or elsewhere.
Radioactive Waste
Liquid, solid, or gaseous waste resulting from mining of radioactive ore, production of reactor fuel materials, reactor operation, processing of irradiated reactor fuels, and related operations, and from use of radioactive materials in research, industry, and medicine.

Garbage
Environmental Pollution
Recycling
Dioxins
Chlorinated hydrocarbons containing heteroatoms that are present as contaminants of herbicides. Dioxins are carcinogenic, teratogenic, and mutagenic. They have been banned from use by the FDA.
Methylophilus
Bioreactors
Tools or devices for generating products using the synthetic or chemical conversion capacity of a biological system. They can be classical fermentors, cell culture perfusion systems, or enzyme bioreactors. For production of proteins or enzymes, recombinant microorganisms such as bacteria, mammalian cells, or insect or plant cells are usually chosen.
Methane
Soil Pollutants
Substances which pollute the soil. Use for soil pollutants in general or for which there is no specific heading.
Soil
Urbanization
Biodegradation, Environmental
Elimination of ENVIRONMENTAL POLLUTANTS; PESTICIDES and other waste using living organisms, usually involving intervention of environmental or sanitation engineers.
Waste Disposal, Fluid
The discarding or destroying of liquid waste products or their transformation into something useful or innocuous.
Environmental Health
Environmental Exposure
Air Pollutants
Environmental Pollutants
Electronic Waste
Water Microbiology
The presence of bacteria, viruses, and fungi in water. This term is not restricted to pathogenic organisms.
Conservation of Natural Resources
Environmental Monitoring
The monitoring of the level of toxins, chemical pollutants, microbial contaminants, or other harmful substances in the environment (soil, air, and water), workplace, or in the bodies of people and animals present in that environment.
Malaysia
A parliamentary democracy with a constitutional monarch in southeast Asia, consisting of 11 states (West Malaysia) on the Malay Peninsula and two states (East Malaysia) on the island of BORNEO. It is also called the Federation of Malaysia. Its capital is Kuala Lumpur. Before 1963 it was the Union of Malaya. It reorganized in 1948 as the Federation of Malaya, becoming independent from British Malaya in 1957 and becoming Malaysia in 1963 as a federation of Malaya, Sabah, Sarawak, and Singapore (which seceded in 1965). The form Malay- probably derives from the Tamil malay, mountain, with reference to its geography. (From Webster's New Geographical Dictionary, 1988, p715 & Room, Brewer's Dictionary of Names, 1992, p329)

Bacteria
One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
