Trends in serum levels of emerging and legacy per- and polyfluoroalkyl substances from 2008 to 2018: a longitudinal study in China
Our study provides information on serum PFAS levels in Chinese retired workers in the Dongfeng-Tongji cohort, and highlights that the risk of exposure to novel PFCAs and PFAS alternatives deserves continued attention. For longitudinal studies with long-term follow-up (e.g. more than 5 years), relying only on a single baseline serum PFAS level may generate misclassification bias resulting in expected bias towards the null and affect the estimation of health effects. https://doi.org/10.1289/EHP15340.
