In Yucatan, Mexico, chronic exposure of Mayan population to pesticides is expected as about 30 per cent are drinking polluted water. Residues of organochlorine pesticides (OCP) were monitored in 18 municipalities of Yucatan with high mortality rates due to uterine cervix cancer. 70 blood samples collected from Mayan women living in livestock, agricultural and metropolitan area were analyzed for OCP. Solid Phase Extraction was performed on C18 cartridges and analyzed by Gas Chromatography with Electron Capture Detector. The results showed that the highest OCP levels were detected in blood of women living in the livestock area. OCP detected were endosulfan I (7.35 mu g/mL), aldrin (3.69 mu g/mL, 4,4' DDD (2.33 mu g/mL), 1.39 and 1.46 mu g/mL of delta-HCH. Women from the agricultural area had high concentrations of OCP in their blood, particularly dieldrin (1.19 mu g/mL), and 1.26 mu g/mL of 4,4' DDE. In the metropolitan area, 0.080 mu g/mL of delta-HCH and 0.064 mu g/mL of heptachlore were detected. This monitoring study was also based on epidemiological data of uterine cervical cancer. It was found that environmental factors may have facilitated the infiltration of OCP to the aquifer used for potable water supply. These factors in addition to poverty can have impacts on public health. This first exploratory study suggests that monitoring of OCP in human is important for the establishment of health promotion programs. The integrative analysis of both, environmental and social factors would be helpful to characterize the bioaccumulation of pesticides in humans. (C) 2016 Elsevier Ltd. All rights reserved.
