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 ...
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 ...
The export of toxic waste to less-industrialised countries has developed into a thriving business for waste traders over the past decade. As costs for disposal of hazardous wastes rose dramatically across the industrialised world in the ... Clapp,Jennifer - 《Third World Quarterly》 被引量: 51...
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 ...

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...
Learn about techniques and methods used in chemical process safety management in this lesson. We will discuss pressure relief valves, chemical...
The Effects of Chronic Lifelong Activation of the AHR Pathway by Industrial Chemical Pollutants on Female Human Reproduction Environmental chemicals, such as heavy metals, affect female reproductive function. A biological sensor of the signals of many toxic chemical compounds seems to be the aryl hydroc...
chemometric modelling. Latent factors controlling the hydrogeochemistry of groundwater too are explored. While hazard quotients (HQ) of the chemical parameters (HQNO3−andHQF−) identify ingestion as the prominent pathway, the calculated risk certainty levels (RCL) of the hazard index (HI) values...
Chemical drinking water standards, an example of guesswork?Apart from a few well-known toxic elements such as fluoride, chemical standards for water are based exclusively on non-medical and non-physiological parameters such as corrosion, taste and furring in pipes. In view of the physiological ...
