Seasonal profiles of atmospheric PAHs in an e-waste dismantling area and their associated health risk considering bioaccessible PAHs in the human lung.
Due to the development of the economy, electronic waste (e-waste) has become a new global problem and e-waste dismantling processes are an important source of air pollution. Among the pollutants emitted, polycyclic aromatic hydrocarbons (PAHs) are a severe concern because of their carcinogenic and mutagenic properties. However, few studies have investigated the atmospheric PAHs generated by e-waste dismantling in a specific region, especially the PAH levels throughout the year. ⋯ Among the sites sampled, the pollutant levels and cancer risk were highest at the EP site, and they could pose a cancer risk for humans, although only the bioaccessible PAHs in human lungs were considered. In particular, infants had a higher health risk than adults, thereby suggesting that air pollution with PAHs is a concern in this area. This study provides clear evidence of the requirement for control measurements of e-waste dismantling processes.
