ENVS 3 Properties of Pollutants 0.0 / 5 ? Environmental Science/StudiesPollutionA2/A-levelAQA Created by: scaryCreated on: 04-03-17 16:06 Solubility The measure of how easily the molecules of a pollutant are separated and dispersed in a liquid 1 of 12 Bioaccumulation The process by which a pollutant builds up within a living organisms 2 of 12 Biomagnification Progressive bioaccumulation along a food chain 3 of 12 Mutagen A pollutant that causes chemical changes to DNA. E.g Asbestos, PCBs, ionising radiation and Dioxins 4 of 12 Carcinogen A pollutant that causes cancer. E.g Asbestos, DDT and cadmium 5 of 12 Teratogen A pollutant that causes uninhabited birth abnormalities E.g Herbicide 2,4,5T 6 of 12 Synergism The interaction between the effects of pollutants that exaggerate an overall effect. E.g Oxides of Nitrogen and Sulphur Dioxide 7 of 12 Persistence A measure of how easily a pollutant is broken down, and therefore how long it remains in the environment. E.g CFCs, Heavy metals 8 of 12 Specifity A measure of the differing toxicity to different organisms. E.g Pyethoid Insecticides are more harmful to insects than mammals. 9 of 12 Toxicity The measure of how poisonous a pollutant is (usually caused by enzyme inhibition) E.g carbon monoxide, lead and DDT 10 of 12 Biodegradability The measure of how easily a pollutant is broken down by decomposers such as fungi and bacteria 11 of 12 Mobility A measure of how easily a pollutant moves in the environment 12 of 12
