Clarification the causes of Arsenic (As) contamination in the landfills of Thailand
Abstract:
I analyzed the heavy metal in the leachate of the landfill and the near groundwater and evaluated the degree of the pollution.
It was found in the previous reports that the arsenic, manganese and lead of the leachate were over the standards of the
Thailand industrial effluent quality. Therefore I studied the cause of such heavy metal pollution and considered the
countermeasure is nenecessary. I sampled the soil and leachate of the landfill. I preprocessed to dissolve the soil and
analyzed the heavy metal by ICP-MS. In addition I tested to find where arsenic comes from, from the soil or the garbage.
In addition I found field working in the different cultures and countries is very hard. Now I could image and understand how
the working in Asian, African or other countries is difficult. I could analyze and test the leachate and soil of landfill. I found the
arsenic in landfill is not coming from soil. Through this oversea training I found my specialty and confidence spread widely
and deeply.
Key words: Landfill, Soil pollution, Arsenic contamination, Water pollution
