全氟辛烷磺酸（PFOS）和全氟辛酸（PFOA）已被证明具有全球分布性、环境持久性和生物累积性。虽然有证据表明这些化合物存在于非职业接触者的血清中，但导致全氟辛烷磺酸和全氟辛酸存在的途径尚未得到很好的表征。对日本家庭收集的真空吸尘器灰尘中的全氟辛烷磺酸和全氟辛酸浓度进行了测量。在所有灰尘样本中都检测到了这些化合物，全氟辛烷磺酸的浓度范围为11-2500 ng/g，全氟辛酸为69-3700 ng/g。研究结果表明，室内灰尘中存在PFOS和PFOA，灰尘的吸附可能是人体接触PFOS和PFOA的途径之一。关于风险管理，必须考虑在室内环境中使用全氟辛烷磺酸和全氟辛酸，以避免进一步污染。
Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are shown to be globally distributed, environmentally persistent and bioaccumulative. Although there is evidence that these compounds exist in the serum of non-occupationally exposed humans, the pathways leading to the presence of PFOS and PFOA are not well characterized. The concentrations of PFOS and PFOA in the vacuum cleaner dust collected in Japanese homes were measured. The compounds were detected in all the dust samples and the ranges were 11-2500 ng g(-1) for PFOS and 69-3700 ng g(-1) for PFOA. It was ascertained that PFOS and PFOA were present in the dust in homes, and that the absorption of the dust could be one of the exposure pathways of the PFOS and PFOA to humans. With regard to risk management, it is important to consider the usage of PFOS and PFOA in the indoor environment in order to avoid further pollution.
