The BSF is a robust water treatment technology for use in rural Cambodian households, capable of effective removal of bacteria, and significant reduction of diarrheal disease. BSF performance is comparable to other recommended household water treatment interventions. The Water and Sanitation Program is an international partnership for improving water and sanitation sector policies, practices, a...

398 Nitrate and nitrite Nitrate (NO 3 ) is found naturally in the environment and is an important plant nutrient. It is present at varying concentrations in all plants and is a part of the nitrogen cycle. Nitrite (NO 2 ) is not usually present in significant concentrations except in a reducing environment, as nitrate is the more stable oxidation state. It can be formed by the microbial reductio...

IARC classified PCP in Group 2B (possibly carcinogenic to humans) on the basis of inadequate evidence of carcinogenicity in humans but sufficient evidence in e xperimental animals. There is suggestive, although inconclusive, evidence of the carcinogenicity of PCP from epidemiological studies of populations exposed to mixtures that include PCP. Conclusive evidence of carcinogenicity has been obt...

Drinking water quality monitoring using trend analysis.

One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled measure...
