每一個孕婦胎盤中至少有一種殺蟲劑。

    據一項新的來自西班牙的研究指出：每一個孕婦的胎盤中至少有一種殺蟲劑，甚至胚胎中也發現。

    María José López Espinosa——來自西班牙格拉納達大學（Granada）大學放射科及物理醫學系，她的博士論文中研究指出：通過分析胎盤后發現，其中存在17中內分泌干擾性有機氯殺蟲劑。

    研究還指明，胎盤組織中存在的殺蟲劑最多的依次是：DDE（一種DDT的乙烯代謝產物，屬于有機氯殺蟲劑）92.7%，lindane（林丹） 74.8%, endosulfan diol（二醇硫丹） 62.1% 以及endosulfan-I（異硫丹） 54.2%.在這些中最普遍的是二醇硫丹，它的平均濃度為每克胎盤組織中富集4.15毫微克，令人驚訝的是，668例孕婦樣本中，一些患者的胎盤中甚至含有15～17 種殺蟲劑。

    在UGR的實驗研究中，推進做了暴露組（母親胎盤中發現殺蟲劑）與親代、新生兒和分娩相關系特征的研究，以下方面與暴露有關：年老，高體重指數，孕期體重增加較小，低教育水平，高工作暴露，初產婦，低出生體重兒。

   據López說：“雖然我們并不完全了解兒童期暴露于干擾性殺蟲劑的后果，但是我們能預測到會有眼中嚴重影響，畢竟這種情況發生于胚胎生長的關鍵期。”研究組進行了幾組研究了新生兒出生畸形泌尿生殖系統與殺蟲劑暴露的關系，以泌尿生殖系統為例，如睪丸未降、尿生殖褶未閉等。

    研究人員還強調說：通過健康、平衡的合理的飲食，低化學含量食品的攝入等，控制殺蟲劑食入是有可能的，此外，日常的鍛煉與禁煙也是非常重要的用來幫助控制殺蟲劑存在量的習慣。

 

 

In her doctoral thesis, María José López Espinosa, from the Department of Radiology and Physical Medicine of the University of Granada (UGR), studied the presence of 17 endocrine disruptive organochlorine pesticides through the analysis of the placentas.
     The results showed that the most frequent pesticides present in the placenta tissue are DDE (92.7%), lindane (74.8%), endosulfan diol (62.1%) and endosulfan-I (54.2%). Among these, the most prevalent was endosulfan-diol, with an average concentration of 4.15 nanograms per gram of placenta. Surprisingly, the UGR researcher discovered that some patients’ placentas contained 15 of the 17 pesticides analysed. A total of 668 samples from pregnant women were used.

The study made at the UGR has facilitated research into the association of the characteristics of parents, newborn babies and childbirth with exposure to pesticides found in the mothers’ placenta. Among the aspects associated with a higher presence of pesticides we find an older age, higher body mass index, less weight gained during pregnancy, lower educational level, higher workplace exposure, first-time motherhood and lower weight in babies.
     According to López, “we do not really know the consequences of exposure to disruptive pesticides in children, but we can predict that they may have serious effects, since this placenta exposure occurs at key moments of the embryo’s development”. The research group has conducted several studies which associate exposure to pesticides with neonatal malformations if the genito-urinary system, such as undropped testicles and total fusion of the urethral folds.
    The UGR researcher underlines that “it is possible to control pesticide ingestion by means of a proper diet, which should be healthy and balanced, through consumption of food whose chemical content is low. Moreover, daily exercise and the avoidance of tobacco are very important habits which help to control the presence of pesticides in our organisms.”
