Biological treatment ofhazardous wastes has the potential for effective, practical, and economical remediation ofsome Superfund sites and other hazardous waste problems. Some biological hazardous waste treatments may also be applicable for preventing the occurrence of future hazardous waste sites. From a public health perspective, this technology may allow for the treatment of environmental haz...

The hazardous materials risk management process involves a set of crucial logistical decisions referring to the planning of the hazardous materials transportation and the organization of the emergency response operations. The objective of this paper is to present a Decision Support System for hazardous Materials Transportation Risk Management that covers integrated hazardous materials distribut...

The presence of toxic metals in drinking water has hazardous effects on human health. This study was conducted to develop GFP-based-metal-binding biosensors for on-site assay of toxic metal ions. GFP-tagged ArsR and CadC proteins bound to a cis element, and lost the capability of binding to it in their As- and Cd-binding conformational states, respectively. Water samples containing toxic metals...

BACKGROUND Although the hazardous tasks adolescent workers perform in service and retail industries are well documented, little is known about the extent to which young workers recognize these tasks as hazardous or dangerous. METHODS Using data from a nationally representative cross-sectional telephone survey conducted in 2003, we examined hazardous task recognition among 858 adolescents work...

Reproductive function has been shown to be sensitive to changes in the physical, psychosocial and chemical environments. Although reproductive effects of occupational exposure to hazardous chemicals have been well documented in the literature, the potential effects of chemical contaminants at levels representative of contemporary exposures in the general population are much less certain. Eviden...
