Abstract

Fly ash from Mae Moh power plant in Lampang province, northern Thailand (unit 6, 8, 10 and 11) was investigated to find out the heavy metals (As, Cd, Hg, Pb and Zn) content of fly ash. Every metal content except mercury is at higher level than the background soil. The average arsenic content was two times higher than the background soil and unit 11 contains the largest amount of arsenic (148.5 mg kg-1). Mercury content of fly ash in the dumping site was not detectable. Sludge, end product of wastewater treatment plant, from Nong Kaem wastewater treatment plant was also investigated. The average arsenic content was higher in fly ash (89.56 mg kg-1) than sludge (22.01 mg kg-1) whereas cadmium, lead, zinc and mercury content was higher in sludge (0.56, 306.07, 1963.23 and 3.97 mg kg-1 respectively) than fly ash (0.46, 10.07, 90.73 and 0 mg kg-1).
