Acute Exposure Guideline Levels

Acute Exposure Guideline Levels set levels of chemical concentration that pose a defined level of risk to humans. These levels are used in preventing and responding to disasters. These guidelines are ascertained for one, short exposure by the air. The AEGL values are determined for varying times of exposure, such as ten minutes, thirty minutes, one hour, four hours and eight hours. The AEGL values describe the expected effects of inhalation exposure to certain compounds airborne concentrations in ppm or mg/m 3. Each AEGL is determined by different levels of a compounds toxicological effect ...

ADR (treaty)

ADR, formally the European Agreement of 30 September 1957 concerning the International Carriage of Dangerous Goods by Road, is a 1957 United Nations treaty that governs transnational transport of hazardous materials. "ADR" is derived from the French name for the treaty: A ccord europeen relatif au transport international des marchandises D angereuses par R oute). From 1 January 2021, the treaty will be renamed Agreement concerning the International Carriage of Dangerous Goods by Road as the term "European" in the incorrectly may give the impression that the treaty is only open for accessio ...

Adverse outcome pathway

An adverse outcome pathway is structured representation of biological events leading to adverse effects and is considered relevant to risk assessment. The AOP links in a linear way existing knowledge along one or more series of causally connected key events between two points - a molecular initiating event and an adverse outcome that occur at a level of biological organization relevant to risk assessment. The linkage between the events is described by key event relationships that describe the causal relationships between the key events. AOPs are important for expanding the use of mechanist ...

Bamako Convention

The Bamako Convention is a treaty of African nations prohibiting the import of any hazardous waste. The Convention was negotiated by twelve nations of the Organisation of African Unity at Bamako, Mali in January, 1991, and came into force in 1998. Impetus for the Bamako Convention arose from the failure of the Basel Convention to prohibit trade of hazardous waste to less developed countries LDCs, and from the realization that many developed nations were exporting toxic wastes to Africa. This impression was strengthened by several prominent cases. One important case, which occurred in 1987, ...

Basel Convention

The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal, usually known as the Basel Convention, is an international treaty that was designed to reduce the movements of hazardous waste between nations, and specifically to prevent transfer of hazardous waste from developed to less developed countries. It does not, however, address the movement of radioactive waste. The Convention is also intended to minimize the amount and toxicity of wastes generated, to ensure their environmentally sound management as closely as possible to the source of genera ...

Basic precipitation

Basic precipitation or Alkaline precipitation occurs when either calcium oxide or sodium hydroxide is emitted into the atmosphere, absorbed by water droplets in clouds, and then falls as rain, snow, or sleet. Precipitation containing these compounds can increase the pH of soil or bodies of water and lead to increased fungal growth. The principal cause of basic rain is emissions from factories and waste deposits. Mineral dust containing large amounts of alkaline compounds such as calcium carbonate can also increase the pH of precipitation and contribute to basic rain. Basic rain can be view ...
