Carcinogenic Effects

Organochlorine pesticides (OCPs) including Hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) in surface water of Lake Baiyangdian were determined to assess the potential health risk when using as drinking water for children and adults. The concentration of HCHs and DDTs in surface water were in the range of 2.74-11.50 ng L-1 and 3.48-16.88 ng L-1, respectively. Compared with similar results reported around the world, the level of OCPs in this study was in the mid-range. The analysis of health risk indicated that risks from OCPs in most part of the lake would not be risky to human health according to the acceptable risk level, while carcinogenic effects caused by α-HCH might occur if drinking water from Nanliuzhuang (NLZ) and Laowangdian (SCD). α-HCH and β-HCH were the dominating factors for carcinogenic and non-carcinogenic risks, respectively. Risks of OCPs for children were much higher than those caused by OCPs for adults.

Abstract Centralized groundwater sources are the main source for drinking, domestic, industry, and agriculture in Central China. Thirty-five centralized groundwater sources were selected to determine the concentration and distribution characterization of nitrate in Wanbei Plain, Anhui Province. Meanwhile, the health risk assessment model recommended by USEPA was used to evaluate the potential health risk for adults and children. The results showed that the average concentration of nitrate in the pore water is lower than that of karst water, which may be attributed to the thinner thickness of loose sediments for karst water. The nitrate in groundwater mainly originates from chemical fertilizers, industrial and domestic waste. The health risk of nitrate to children through drinking water intake and skin contact was significantly higher than that of adults, which was explained by their being more sensitive receptors and facing higher health risks than adults. The non-carcinogenic risk of nitrate in all samples was within the acceptable range. The results also indicated drinking water control is the main way to reduce nitrate health risk. Nevertheless, there is an urgent need to take measures to strengthen groundwater management, improve groundwater quality, and reduce nitrate health risk.

Health Risk Perception

A substantial proportion of drinking water consumers have resorted to alternatives to their municipal water supply as their source of drinking water. Although health risk perceptions associated with drinking water are ranked low in comparison with other risks, they are subject to influence from the media as a primary information source. Although there may not be a strong connection between odour detection and health risk, consumers who make such a connection cannot be dismissed as irrational. There are substantial grounds to support the possibility that unfamiliar drinking water odours might reveal the presence of substances which pose a potential health risk. Failure to provide credible evidence as to the actual causes of odours will leave water utilities in an indefensible position on associated health risk.
