妊娠期全氟化合物暴露水平及对子代健康影响

Level and effect of maternal exposure to perfluorinated compounds on health of offspring in human: an overview

  • 摘要: 全氟化合物(PFCs)是一类新型持久性有机污染物,广泛应用于工业生产和日常生活。这类化合物稳定性高,易与蛋白质结合并在生物体内蓄积,因此广泛存在于环境和生物中。孕妇血液、脐血、羊水和母乳中均可检出该类物质,提示子代胎儿期即可暴露于PFCs。目前,针对母亲孕期PFCs暴露对子代健康的影响已经开展了较多流行病学研究,研究结局包括子代出生结局、神经行为发育、免疫系统疾病及生殖健康。并且有研究发现产前暴露于PFCs可能会降低子代出生体重,造成神经发育异常、免疫力降低以及延迟生殖发育,但是另外一些研究并未观察到一致的结果。既往研究纳入的人群特征不同,PFCs暴露水平差异较大,采用的结局指标也不尽相同,可能是研究结论不一致的原因。目前尚不能确定人类妊娠期PFCs暴露对子代生长发育的确切影响,仍需开展大样本量的队列研究,以明确PFCs暴露和子代生长发育的关系。

     

    Abstract: Perfluorinated compounds (PFCs), as a kind of emerging persistent organic pollutants, have been widely used in industrial production and daily life. PFCs are highly stable and can easily bind to proteins and accumulate in organisms. Therefore, PFCs were widely distributed in the environment and human bodies. PFCs could be detected in maternal blood, umbilical blood, amniotic fluid, and breast milk, suggesting that fetus may exposed to PFCs in utero. Epidemiological studies have been conducted to examine the relationship between maternal exposure to PFCs and health outcomes of offspring including birth outcomes, neurobehavioral development, immune system diseases, and reproductive health. Several studies have reported that maternal exposure to PFCs were associated with lower birth weight, abnormal neurodevelopment, changed immunity, and delayed reproductive development. However, the results were not consistent in previous studies. The characteristics of study population, levels of exposure to PFCs and outcome measurements were significantly different in the studies, which may be the reason for the inconsistent findings. Large cohort studies with a long-term follow up are still needed to evaluate the effects of PFCs exposure in the development of offspring.
