DESCRIPTION (provided by applicant): Perfluoroalkyl acids (PFAAs) are a class of man-made compounds developed after World War II for use as plasticizers, wetting agents, and as emulsifiers during industrial manufacturing processes. Two of the most common PFAAs are the 8-carbon chain chemicals perfluorooctanoic acid (PFOA or C8) and perfluorooctane sulfonate (PFOS or C8 sulfonate [C8S]). Recent, growing concern about possible health effects of PFAAs is the result of evidence that: PFAAs have a long half-life and environmental persistence; animal studies suggesting that PFAAs have deleterious effects, including carcinogenesis, and other disruptions to normal physiology; evidence of their widespread presence in human sera; and human population studies that have provided early evidence for potential exposure- related health effects. In the United States, the EPA- led PFOA Stewardship Program aims to eliminate PFOA from all emissions and products by 2015. In the European Union, the use of PFOS and derivatives was stopped in 2000 and banned in 2008, though PFOA use remains largely unregulated. As a result of this regulation, industrial manufacturers and users of PFOA or PFOS have needed to develop alternate chemicals and processes, and non-8-carbon chain PFAAs have emerged as replacement chemicals. However, almost no publically available scientific evidence exists regarding the human or environmental safety of these chemicals. The primary objective of this proposal is to determine the associations between non-8-carbon perfluoroalkyl acids (PFAAs) and serum parameters of lipid, liver, and kidney function in children. We are requesting funding to perform secondary analysis on data collected as part of the C8 Health Project, a community cohort study with 69,030 participants including more than 12,000 children.

We are requesting funding to perform secondary analysis on data collected as part of the C8 Health Project, a community cohort study with 69,030 participants, including more than 12,000 children, created pursuant to the pre-trial settlement of a class action lawsuit filed after PFOA contamination of drinking water supplies along the mid-Ohio River valley.

描述（由申请人提供）：全氟烷基酸（PFAAs）是第二次世界大战后开发的一类人造化合物，在工业制造过程中用作增塑剂、润湿剂和乳化剂。两种最常见的PFAAs是8碳链化学品全氟辛酸（PFOA或C8）和全氟辛烷磺酸（PFOS或C8磺酸盐[C8S]）。最近，人们越来越关注PFAAs可能对健康造成的影响，因为有证据表明：PFAAs具有较长的半衰期和环境持久性；动物研究表明，PFAAs具有有害影响，包括致癌和其他对正常生理的破坏；它们在人类血清中广泛存在的证据；人口研究已经提供了潜在的暴露相关的健康影响的早期证据。在美国，由环境保护署领导的全氟辛酸管理计划旨在到2015年从所有排放物和产品中消除全氟辛酸。在欧盟，全氟辛烷磺酸及其衍生物的使用于2000年停止，并于2008年被禁止，但全氟辛烷磺酸的使用在很大程度上仍未受到监管。由于这一规定，全氟辛烷磺酸或全氟辛烷磺酸的工业制造商和用户需要开发替代化学品和工艺，非8碳链全氟辛烷磺酸已成为替代化学品。然而，关于这些化学品对人类或环境的安全性，几乎没有公开的科学证据。本提案的主要目的是确定非8碳全氟烷基酸（PFAAs）与儿童血脂、肝肾功能的血清参数之间的关系。我们正在申请资金，对作为C8健康项目一部分收集的数据进行二次分析。C8健康项目是一项社区队列研究，有69,030名参与者，其中包括12,000多名儿童。为了方便读者阅读本应用程序，下表总结了本应用程序中使用的主要缩写：全氟烷基酸（PFAA）简称碳长PFHxA全氟己酸C6 PFHS全氟己烷磺酸铵C6S/C6磺酸PFHpA全氟庚酸C7 PFOA全氟辛酸C8 PFOS全氟辛烷磺酸C8S/C8磺酸PFNA全氟己酸C9 PFDA全氟癸酸C10临床健康参数简称全称LDL胆固醇低密度脂蛋白胆固醇HDL胆固醇高密度脂蛋白胆固醇AlkPhos碱性磷酸酶ALT丙氨酸转氨酶AST天冬氨酸转氨酶BiliDirect直接胆红素总胆红素GGT谷氨酰基转移酶LDH乳酸脱氢酶BUN血尿素氮
