毒理性
识别和使用:全氟庚酸(PFHpA)是一种米色的结晶固体。它被归类为长链全氟烷基羧酸。这些酸及其衍生物被用作润湿、分散、乳化以及起泡剂。人类暴露和毒性:研究人员研究了105名男性,并确定在高睾酮组和低睾酮组之间的平均PFHpA水平没有差异。在儿童中,有或无哮喘的PFHpA血清水平有显著差异,尽管中位数水平相同。有或无子宫内膜异位的女性之间PFHpA的平均血清水平没有差异。在韩国的一项研究中,PFHpA在母体血清、脐带血清或人乳中未被检测到。动物研究:研究了PFHpA(以及其他全氟化羧酸)对两种不同哺乳动物细胞系和一种海洋细菌的细胞毒性。结果显示,这些化合物具有非常低的急性生物活性。全氟庚酸对雄性和雌性大鼠肝脏中积累甘油三酯和诱导过氧化物酶体β-氧化的能力没有影响。
IDENTIFICATION AND USE: Perfluoroheptanoic acid (PFHpA) is a beige crystalline solid. It is categorized as a long-chain perfluoroalkanecarboxylic acid. These acids and derivatives are used as wetting, dispersing, emulsifying, and foaming agents. HUMAN EXPOSURE AND TOXICITY: Researchers studied 105 men and determined that there was no difference in mean PFHpA levels between those with high testosterone and those with low testosterone. In children, a significant difference in serum levels of PFHpA between those with or without asthma was reported, although median levels were the same. No difference in mean serum levels of PFHpA were reported in women with or without endometriosis. In a study in South Korea, PFHpA was not detected in maternal sera, cord sera, or human milk. ANIMAL STUDIES: The cytotoxicity of PFHpA (among other perfluorinated carboxylic acids) towards two different types of mammalian cell lines and one marine bacteria was investigated. The results show these compounds have a very low acute biological activity. Perfluoroheptanoic acid had no effect on the potency to accumulate triglyceride and induction of peroxisomal beta-oxidation in the liver of male and female rats.
