The objective of this study was to determine the levels of organochlorine pesticides HCB, α-β-γ-HCH, p,p'-DDE, o,p'-DDT and p,p'-DDT in 150 adipose tissue of inhabitants of Tabasco, Mexico. The following pesticides were detected: p,p'-DDE in 100% of samples at mean 1.034 mg/kg; p,p'-DDT in 96.7% at mean 0.116 mg/kg; o,p'-DDT in 78.7% at mean 0.022 mg/kg and β-HCH in 58.0% at mean 0.049 mg/kg. The pooled sample was divided according to sex of donors (75 female and 75 male). Significantly higher levels of all organochlorine pesticides in females were found. The sample was divided into three age's ranges (15-28, 29-45 and 46-84 years). The mean and median levels of β-HCH, p,p'-DDE and Σ-DDT increase significantly (p < 0.05) from the first to the second and third group. The presence of organochlorine pesticide residues in Tabasco inhabitants is still observed, indicating sources of exposure to the pesticides.
本研究的目的是测定 150 例来自墨西哥塔巴斯科州居民的脂肪组织中有机氯农药 HCB、α-β-γ-六氯环己烷、p,p'-DDE、o,p'-DDT 和 p,p'-DDT 的浓度。检测到以下农药：p,p'-DDE 在 100%的样本中浓度为 1.034mg/kg；p,p'-DDT 在 96.7%的样本中浓度为 0.116mg/kg；o,p'-DDT 在 78.7%的样本中浓度为 0.022mg/kg；β-HCH 在 58.0%的样本中浓度为 0.049mg/kg。根据供体的性别（75 名女性和 75 名男性）将 pooled sample 进行分组。发现女性体内所有有机氯农药的浓度均显著更高。将样本分为三个年龄段（15-28 岁、29-45 岁和 46-84 岁）。β-HCH、p,p'-DDE 和 Σ-DDT 的平均值和中位数水平从第一组到第二组和第三组显著增加（p<0.05）。塔巴斯科州居民体内仍存在有机氯农药残留，表明存在接触这些农药的来源。
