Air pollution is a critical public health concern. The present study assessed the risk to human health of airborne Potentially Toxic Elements (PTE) arsenic, nickel and lead exposure in particulate matter (PM) in Sao Paulo, Brazil. Statistical analysis was performed using R Software and the risk assessment for human health was carried out according to the methods of the United States Environmental Protection Agency. The results for mean annual concentration of PTE (ng m) were within the limits stipulated for air-quality by international agencies (arsenic <6, nickel <20 and lead <150). Airborne arsenic and lead showed higher mean concentrations during the winter than the other seasons ( < 0.05). However, the results showed a greater health risk for the adult population and during the winter season. These findings highlight the importance of air pollution as a risk factor for population health.
空气污染是一个严重的公共卫生问题。本研究评估了巴西圣保罗空气中的空气传播潜在有毒元素（PTE）砷、镍和铅暴露对人类健康的风险。统计分析使用 R 软件进行，根据美国环境保护署的方法进行了人类健康风险评估。PTE（ng m）的年平均浓度结果在国际机构规定的空气质量限值内（砷 <6、镍 <20 和铅 <150）。空气传播砷和铅在冬季的平均浓度高于其他季节（<0.05）。然而，结果表明，成年人群在冬季面临更大的健康风险。这些发现强调了空气污染作为人口健康风险因素的重要性。
