Particulate matter (PM10) is a major pollutant of concern as it can be adsorbed with toxicsubstances like heavy metals and organic compounds like polycylic aromatic hydrocarbons(PAH). Automobile exhaust was among the most significant contributor towards the particulatematter problem in roadside areas of Malaysia. In addition, most of the school in Malaysia locatedclose to the roadside to ease accessibility that consequently further increase health risk amongchildren. In this study, aerosol samples from school ambient in urban area (Kota Bharu) and ruralarea (Jeli) were analysed for PAH and concentration of heavy metal (Pb, Zn and C) identification.Result found the concentration of PM10 was higher in urban site than rural site with meanconcentration Kota Bharu and Jeli is 52.57?g/m3 and 39.21 ?g/m3 respectively. The 1-methylnaphthalene was the only PAH detected in both urban and rural areas. Result suggestedthat the concentration of lead (Pb) is the most prominent heavy metal measured in Jeli, whileconcentration of zinc (Zn) is the most significant of heavy metal in Kota Bharu.

Abstract Heavy metal pollution in the air, water, and soil has attracted substantial interest recently; however, assessment of the total human environmental exposure remains limited. Therefore, determining the total human environmental exposure is imperative for the management and control of heavy metal pollution. This study assessed the total environmental exposure levels of heavy metals as well as the exposure contributions of air, water, and soil, focusing on Hg, Cd, As, Pb, and Cr. Data from 3,855 volunteers from the cities of Taiyuan, Dalian, Shanghai, Wuhan, Chengdu, and Lanzhou allowed for comparison of the exposures in urban and rural areas. The levels of total human environmental exposure of Hg, Cd, As, Pb, and Cr were 1.82 × 10−6 mg/(kg·d), 1.58 × 10−6 mg/(kg·d), 3.87 × 10−5 mg/(kg·d), 1.79 × 10−5 and 7.47 × 10−5 mg/(kg·d), respectively. There were regional, urban-rural, sex, and age differences in the levels of heavy metal exposure. Water pollution was determined to be the largest contributor to heavy metal exposure, accounting for 97.87%, 92.50%, 80.51%, 76.16% and 79.46% of the Hg, Cd, As, Pb, and Cr, followed by air and soil pollution. These results can provide data to inform environmental protection policies and identify the priority pollutants that can help identify and prevent health risks due to overexposure to these heavy metal pollutants.
