摘要

Bisphenols (BPs) and parabens are widespread endocrine disruptors that enter outdoor environments due to daily activities and industrial manufacturing processes. Currently, research on population exposure to BPs and parabens through outdoor environmental media remains limited. Seven BPs and five parabens were detected in both soil and outdoor dust. Five distinct BPs (BPA, BPS, BPF, BPAF, and BPAP) and four types of parabens (MeP, EtP, PrP, and BuP) demonstrated high detection rates in both soil and outdoor dust, with rates surpassing 90%. Among these compounds, BPA was the primary constituent found in both the soil and outdoor dust, exhibiting mean concentrations of 3.698 μg/kg and 56.032 μg/kg, respectively. The levels of BPs and parabens in outdoor dust were notably greater than those detected in soil. The maximum hazard index (HI) values for both adults and children typically stayed beneath the safety threshold (2.76 × 10–8 to 2.33 × 10–5), which implies that the health risk of exposure to BPs and parabens through interaction with soil and outdoor dust is relatively low for the population. However, potential risks associated with long-term exposure require careful monitoring.
