Analytical techniques for the detection of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo(5.5.0.05,9.03,11)dodecane (CL-20) in water and soil are developed by adapting methods traditionally used for the analysis of nitroaromatics. CL-20 (a new explosives compound) is thermally labile, exhibits high polarity, and has low solubility in water. These constraints make the use of specialized...

Biotyping and DNA fingerprinting by pulsed-field gel electrophoresis were applied to a collection of enterococci recovered from recreational and drinking water, in order to identify possible genetic relationships. Clinical strains of hospital origin were compared to the environmental isolates. A total of 104 enterococci were isolated from 128 recreational water (94 marine and 34 river water) an...

There are numerous indicators that Hispanics face a disproportionate risk of exposure to environmental hazards. Ambient air pollution, worker exposure to chemicals, indoor air pollution, and drinking water quality are among the top four threats to human health and are all areas in which indicators point to elevated risk for Hispanic populations. These data, juxtaposed with data on the health st...

This research is aimed at analizing the effect of environmental management policy implementation on water pollution control to improve the environmental quality. The analytical method used is this study is a literature review that uses effectual causal analysis approach based on literature review, with the object of research conducted in Garut District, Indonesia. The result of discussion shows...

Characterization of stream flow is essential to water resource management, water supply planning, environmental protection, and ecological restoration; while air temperature variation due to climate change can exacerbate stream flow and add instability to the flow. In this study, the wavelet analysis technique was employed to identify temporal trend of air temperature and its impact upon forest...

Spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. The use of an appropriate sample handling technique is a...

Study of the ground water quality in Hodeidah is an essential ingredient for a healthypopulation. In this research, study of drinking water samples for eight water sources wells in theQuti field has been achieved. The purpose was to a certain the quality of water from thesesources, the physical properties such as pH, electrical conductivity (EC) and total dissolvedsolids (TDS), showed the varia...
