Terrorism poses a clear and present danger to civilian populations. Although terrorist cells may gain access to traditional chemical weapons,there are literally thousands of other industrial chemicals to choose from. Common chemicals used on a daily basis in an industrialized society can be readily obtained from the local shopping center, rail yard. or from nearby industrial parks. and terroris...

Hazardous chemicals are harmful to the people around them during their storage, especially when an accident occurs. The allocation and scheduling of emergency materials, therefore, is important imperative rescue services. Due characteristics dangerous goods, storage risk hazardous in networks always exists, which threatens surrounding residents. To reduce terms networks, collaborative optimizat...

INTRODUCTION Flooding accounts for about 40 per cent of all natural disasters that occur worldwide. In 2002-2003 many counties in England experienced severe floods. Floods are particularly important in public health terms as they may have multiple environmental consequences. METHODS Details of floods reported to Chemical Hazards and Poisons Division, London [CHaPD(L)] were analysed and a lite...

Although the efficacy of insecticide-treated nets (ITNs) in malaria prevention is well documented, the low coverage of ITNs in malaria endemic countries necessitates investigation on factors that limit access to this intervention. An exploratory study was conducted in Mukono district, Uganda, to assess perceptions and use of ITNs. Results show that malaria is perceived as a serious illness amon...

The idea that synthetic chemicals such as DDT are major contributors to human cancer has been inspired, in part, by Rachel Carson's passionate book, Silent Spring. This chapter discusses evidence showing why this is not true. We also review research on the causes of cancer, and show why much cancer is preventable. Epidemiological evidence indicates several factors likely to have a major effect ...

The nuclear receptor member human pregnane X receptor (hPXR) regulates enzymes and transporters involved in xenobiotic detoxification as well as maintains homeostatic balance of bile acids, thyroid and steroid hormones. hPXR can be recognized and activated by a structurally diverse array of environmental chemicals and drug compounds to initiate adverse biological effects, such as perturbing nor...

A low-cost yet highly sensitive colorimetric sensor array for the detection and identification of toxic industrial chemicals (TICs) has been developed. The sensor consists of a disposable array of cross-responsive nanoporous pigments whose colors are changed by diverse chemical interactions with analytes. Clear differentiation among 20 different TICs has been easily achieved at both their IDLH ...
