The Concentration of Cadmium, Lead, and Mercury in Dust Fall During the Sugar Cane Harvesting Period in the Muang District, Kamphaeng Phet Province

Abstract

This research examined the concentration of heavy metals (mercury, cadmium and lead) in dust fall during the sugar cane harvesting period.  The study area included eight sampling sites  located Mueang District, Kamphaeng Phet Province and using a dust container (Dust fall Jar Container) for 30 days. Total sampling was conducted for three months from February-April 2017. The sampling area at the 6^th point had the highest amount of dust in every month, and in March, the maximum dust content was 29.05x10^-3 mg/m²/day. The lowest sample was found in February at the 8^th spot. The lowest amount of dust was 0.85x10^-3 mg/m²/day. Each dust collection point did not exceed the dust reference value that was detected in various locations, Thailand, no more than 65-130 mg/m²/day. Analysis of heavy metals including lead, mercury, cadmium showed the highest lead concentration in each month, the highest lead month was February at 46.93 ppb. The highest cadmium in February was 13.18 ppb. Furthermore the lowest concentration is the highest mercury in February 0.27 ppb
