fraction of the halogenated organic compound which can be adsorbed to activated carbon and thus is easily quantified

accumulation of fat-soluble and stable pollutants in fat tissues in animals, typically fat, liver and brain in man, egg yolk in birds, and mothers milk

the amount of oxygen used for biological decomposition during a given period of time, 7 or 5 days, used as a measure of discharged organic substance

natural or synthetic chemical compounds toxic to living organisms used to control various plants (weeds) or animals (pests); used in agriculture, forestry and horticulture

the increased concentration of fat-soluble and stable pollutants in the upper parts of a food chain

method to separate individual constituents in a sample between a solid and a mobile phase during their flow in a chromatographic system

variants of a class of organic compounds that differ in e.g. the number of chlorine atoms in the basic structure

emissions caused by the use and, later on, disposal of a product

are a structurally closely related group of hydrophobic chemicals, which are persistent and bioaccumulating, and some of them extremely toxic; Dioxins are polychlorinated dibenzo-p-dioxins (PCDDs). The closely related dibenzofurans (PCDFs) have dioxin-like properties

material which is moved but not used, e.g. the overburden from mining
