Organochlorine pesticides in the drinking water of Merida and its Metropolitan Zone, a Karst Region

Concentrations of organic contaminants (organochlorine pesticides and biphenyls) were studied in bottled drinking water (BDW) from Mexico City where consumption is high and considered a healthy alternative to the potable water network. The results of 36 samples (1.5 L and 19 L presentations, 18 samples of each) showed the presence of seven pesticides (HCH-hexachlorocyclohexane isomers, heptachlor, aldrin and p,p'-DDE'-dichlorodiphenyldichloroethylene) and some polychlorinated biphenyls-PCBs (28, 58 and 101). The concentrations were compared with the drinking water standards set by NOM-127-SSA1–1994, USEPA (United States Environment Protection Agency) and the World Health Organization (WHO) for pesticides and NOM-127-SSA1–1994 for biphenyls. The concentrations of the majority of organochlorine pesticides were within drinking water standards (0.01 μg L−1) except for β-HCH in BDW samples 3, 5 and 6 with values of 0.121, 0.136 and 0.192 μg L−1, respectively. The total PCBs concentration in BDW did not represent any hazard to human health, according to Mexican regulations, which establish a maximum permissible level of 0.50 μg L−1. A BDW quality monitoring program is recommended and further research on ways of reducing the presence of organochlorine contaminants to prevent bioaccumulation and toxicological effects over population with emphasis in those that with constant consumption.

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.

AbstractWater is principally intended for direct consumption and for the production of food and beverages. It is also a valuable raw material in the industry. Despite the use of multi-stage treatment processes, the quality of drinking water may still be a concern in some countries due to the presence of toxic pollutants, often challenging to remove through the conventional treatment process. The presence of even trace amounts of organochlorine pesticides in drinking water is dangerous due to their ability to accumulate in the human body and their effects, especially their capacity for endocrine disruption. The present study aimed to assess the effect of water and sewage treatment on the efficiency of reducing residues of selected organochlorine pesticides in drinking water and treated sewage. It was found that the water treatment process reduced concentrations of these compounds by an average of 80% (46–100%) and that the levels of organochlorine pesticides in the drinking water were no higher than 0.55% the maximum residue limit (MRL). The sewage treatment process led to a reduction in organochlorine pesticide concentration of 37–100%, averaging 85%, and the sums of organochlorine pesticide residues in treated sewage ranged between 0.02 and 14.97 ng/L in annual terms.
