Assessment of Heavy Metal Content in PM10 at Amphoe Mueang Pathum Thani Province in Thailand
Abstract:
Pathumthani is a metropolitan area where has a lot of industries and agricultures. The aim of this work was to study the assessment of heavy metal content in PM10 (particulate matter ≤ 10 mm) at Amphoe Muang Pathumthani Province. The samples of PM10 (particulate matter ≤ 10 mm) were collected in 7 stations during February to March 2013. The particles were trapped on glass fiber filters using high volume samplers. The concentration of heavy metals was evaluated by using the Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES). The results showed that the concentration of heavy metals in PM10 was BDL-0.41 µg/m3. Zinc, a heavy metal, was found in every sampling station. The order-average concentration of heavy metals in atmospheric air, at Amphoe Muang Pathumthani, was Zn > Cu > Mn > Ba > Ni > Cd.
