Introduction
Polycyclic aromatic hydrocarbons exist around the human life, and they can be found almost in all nature resources that people need to use every day, such as air, water, soil and food. Some PAHs contains in products or goods such as gasoline, cigarettes, and cosmetics. (Yu, 2005, pp. 178-180) PAHs are common products of incomplete combustion. (Callesen et al., 2013) As a results, some nature incidents like forest fires and volcanic eruption may product PAHs as well as some human activities such as traffic exhaust, industrial emissions, cooking, and smoking. Respiration and ingestion are the common passageway for PAHs entering into human bodies (Yu, 2005, pp. 178-180). As a groups of chemicals with aromatic rings structures, PAHs has been treated as carcinogenic potentials by humans (Yu, 2005, pp. 178-180), and many of PAHs has been determined carcinogenic effects to animals. In my study, I will research in three facts health effects for children exposure conditions, respiration diseases and asthma, child behaviour and intelligent.
Exposure conditions of PAHs in dust for children
The major indoor sources derive from heating, cooking, smoking, or burning candles, in urban region, traffic emissions and fossil fuels combustion are the main contributors of outdoor PAHs (Junk et al., 2012). Soltani et al. (2015) stated that the concentration of PAHs of road dust with a high traffic density are higher than expressway that has light traffic and no industrial. To be…
