Abstract
Semi-volatile organic compounds (SVOCs) are significant contributors to adverse health effects, yet information regarding bedroom SVOCs, their contributions to body burden in children, and associations with health biomarkers is lacking. This study analyzed nearly 1,000 SVOCs in 47 paired bedroom air and dust samples collected in Dalian and Linyi, China, along with 12 phthalate metabolites and 3 biomarkers (malondialdehyde, 8-hydroxydeoxyguanosine, and serotonin) in urine samples collected from child residents. In bedroom environments, 99 SVOCs were identified in air and 141 in dust. The total concentrations of SVOCs ranged from 1.23 to 84.6 μg/m3 in air and from 142 to 4350 μg/g in dust, with phthalates accounting for more than 34.4 % on average. Concentrations of dimethyl phthalate, di-isobutyl phthalate, and di-n-butyl phthalate in bedroom air were significantly associated with their corresponding urinary metabolites. The median contributions of these compounds via bedroom air exposure ranged from 6.96 % to 23.4 % of children's body burden. Multiple linear regression analyses showed that six SVOCs in bedroom environments were significantly associated with serotonin or malondialdehyde levels, with four compounds originating from bedroom air. These findings highlight the non-negligible role of SVOCs from bedroom air in children's body burden, as well as in alterations of oxidative stress and neurotransmitter levels. Overall, the results call for targeted interventions on bedroom air quality to address child health risks associated with SVOC exposure.
