title: [Safety value of contaminant in water pollution accident based on human health risk].
abstract: The acute human health risk assessment of contaminant in water pollution accident is a new study field of environmental sciences. This study established a model for calculating acute safety value of contaminant in water pollutant. The acute safety value of contaminant in mainly water pollution during 2000-2010 was calculated by this model. The safety value of sodium cyanide, cadmium, formaldehyde, ammonia, toluene, nitrobenzene, microcystin-LR were 0.1, 0.6, 8, 20, 6, 0.07, 0.004 mg x L(-1), respectively. The differences of safety value calculate methods between acute and chronic exposure were compared from the following aspects, the toxicology exposure end-point, allocation of intake, exposure sensitive subpopulation.
