Association between size-resolved PM₁₀-bound heavy metal and metalloid exposure and oxidative stress among waste recycling workers.

ABSTRACT: Following the sharp increase in global waste generation, heavy metals and metalloids (HMMs) have become a serious threat to workers in the waste recycling industry. However, our understanding of internal exposure levels of HMMs and the relationship between size-resolved particulate matter (PM)-bound HMMs external exposure with internal exposure and oxidative stress among waste recycling workers are limited. Therefore, we collected first morning void urine samples from 20 participants and size-resolved indoor PM₁₀ samples at least 45 consecutive days. We then detected 21 urinary HMMs, PM₁₀-bound HMMs and oxidative stress biomarkers (OSBs) of DNA (8-hydroxy-2'-deoxyguanosine [8-OHdG]) and lipids [malondialdehyde (MDA)]. The intraclass correlation coefficients for most H
