The concentration of lead in particles and Its health risk assessment at Amphoe Muang Pathumthani Province

Abstract

14 samples of TSP and PMwere collected within the area of Amphoe Muang Pathumthani from 7 stations at Tambon Bang Prok, Bang Duea, Bang Khu Wat, Bang Kradee, Lak Hok, Bang Changand and Kra Sang during February to March 2013, in order to evaluate the concentration of dust and lead concentration level by using ICP-OES. The result of this study shows the TSP ranging 0.03 - 0.32 mg/mmg/mμg/maverage of 0.04 ± 0.06 μg/mμg/m0.05 ± 0.07 μg/m10 3 and the average of 0.12 ± 0.10 3 . The concentration of PM10 is in the range of 0.06 – 0.21 mg/m3 average of 0.13 ± 0.06 mg/m3. Of the determination of lead in TSP concentration of lead found in the range of 0.01 – 0.18 3 3 while lead in PM10 found in the range of 0.01 – 0.21 3 average of 3. Assessment of the public health risk is found contamination of lead in the atmosphere of Amphoe Muang, Pathumthani levels ranged from less dangerous except area Bang Prok is worth the risk is moderate danger.
