These harmful chemicals can be constructions and industrial wastes, chemical spillages and the toxic materials deliberately released to the environment. Releasing toxic substances to the environment has been a way of life for years, but the major problem started with urbanization, that is the ...
Evaluation of chemical fate in the environment has been suggested to be best accomplished using a five-stage process in which a sequence of increasing site... D Mackay,AD Guardo,S Paterson,... - 《Environmental Toxicology & Chemistry》 被引量: 118发表: 2010年 Exposure Modeling in Occupational...
aCoverage for pollution is limited to cleaning up pollution that was caused by a covered cause of loss occurring during the policy period. For example, if vandals opened drums of a toxic chemical and poured it on the ground, the insurer would cover the cost of the cleanup, up to the poli...
In such cases, the incremental response may become diminishingly smaller with increasing dose or exposure because activation of the chemical to the toxic form follows apparent Michaelis鈥擬enten rather than apparent first-order kinetics. To illustrate this concept, rats were exposed to concentrations ...

Drainage basin, are from which all precipitation flows to a single stream or set of streams. The boundary between drainage basins is a drainage divide: all the precipitation on opposite sides of a drainage divide will flow into different drainage basins.
We have studied the long-term toxicity of a Roundup-tolerant GM maize (NK603) and a whole Roundup pesticide formulation at environmentally relevant levels from 0.1 ppb. Our study was first published in Food and Chemical Toxicology (FCT) on 19 September, 2012. The first wave of criticisms arri...
