When humans are exposed to chemicals, they are not exposed to just one chemical at a time. A vast number of chemicals pervade our environment. Exposures, whether simultaneous or sequential, are to chemical mixtures. The standard definition of a chemical mixture is any set of multiple chemicals regardless of source that may or maynot be identifiable thatmay contribute to joint toxicity in a targ...

As do many industries, colleges and universities encounter thorny problems in dealing with hazardous wastes. Industry and academia alike are saddled with the rising cost of waste management and face perpetual liability for costs of waste cleanup. Unlike many industries, however, colleges and universities generate small amounts of waste, most, but by no means all of which is generated in laborat...

The Hazardous Material Removal Program will provide all academic departments and faculty with the opportunity to dispose of unneeded hazardous chemicals and radioactive material with no EH&S recharge. The disposal program will be organized building by building and advanced notice will be given to each department. Radioactive waste and materials along with routine chemical waste will be collecte...

The Regional Ground Water Forum is a group of ground-water technical specialists, representing EPA's Regional Offices, organized to exchange up-to-date information related to groundwater remediation at hazardous waste sites. Proper site characterization has been identified by the EPA Regional Ground Water Forum as a major issue of concern for decision-makers at many hazardous waste sites. In or...

With the commercial availability of integrated microreactor systems, the numbers of chemical processes that are performed nowadays in a continuous flow is growing rapidly. The control over mixing efficiency and homogeneous heating in these reactors allows industrial scale production that was often hampered by the use of large amounts of hazardous chemicals. Accurate actuation and in line measur...

In the past five years, the Illinois Department of Public Health (IDPH) has completed several different aativities aimed at reducing the risk of chemical spills and exposures in schools, including chemical collections, training workshops, and a mercury needs assessment. IDP found that many schools store and use hazardous chemicals in ways that increase the risk of accidents and exposures. As a ...

The proposed siting of new chemical Hazardous Installations, modifications to existing Hazardous Installations, and proposals for development within the vicinity of these installations, are assessed by the Hazardous Installations Directorate (HID) of the Health & Safety Executive. Numerical risk assessment methodology is utilised to enable advice to be given to Local Planning Authorities. The u...

Due to the fragile physicochemical properties of hazardous chemicals, chances leakage and explosion during production, transportation, storage are quite high. In recent years, chemical accidents have occurred frequently, posing a great threat people’s lives property. Hence, it is crucial analyze establish corresponding warning mechanisms safeguard measures. At present, most hazardous-chemical-a...

Detection of traces of toxic chemicals in drinking water supplies, in polar ice caps, groundwater sources and episodes such as those in Minamata Bay, Japan and Love Canal, USA have focussed the attention of the public worldwide on the risks posed by the inappropriate disposal of hazardous waste and accidental release of toxic chemicals into the environment. In India regulations to control and m...
