摘要: The aim of this study was to conduct a POP biomonitoring programme for children in high-risk areas. We evaluated 247 serum samples from between the ages 6 and 12years old two zones Mexico: (1) indigenous zones, which included Cuatlamayan (CUA), Tocoy (TOC), Santa Maria Picula (SAM); (2) industrial Tercera Chica (TC), Industrial San Luis (IND) Rincon de Jose (SJR); Mundo Nuevo (MN); Alpuyeca (ALP). Our results showed that α-endosulfan similar CUA, TOC, SAM, TC MN (178.6-306.9ng/g lipid). β-Endosulfan levels were higher ALP (901.5ng/g lipid), followed by CUA (139.9ng/g lipid) MN, had (55.4-64.5ng/g For endosulfan sulfate, community highest concentration (1096.4ng/g whereas TOC (212.3 289ng/g lipid, respectively) concentrations those found SAM (99.5 119.1ng/g respectively). DDE malaria-endemic areas (1782.2, 1358.3 57.0ng/g (35.1ng/g HCB be SJR (691.8 575.4ng/g respectively), (363.9 269.1ng/g with (191.8 181.9ng/g Finally, PCB 101 (1032.7ng/g IND (567.5 327.3ng/g 109.1 144.5ng/g respectively. evidence provided exploratory indicates evaluation health risks posed living contaminated is high priority issue.
