Abstract:
The agricultural products occupy 19% of total exports in Thailand. In Thailand, pesticides are much used to improve amount, quality and appearance of the agricultural products. There is a lot of research about the residual pesticides in the agricultural products. But there are a few researches about the soil of agricultural products. Other researches show that pesticides cause some health issues of the children whose parents are farmer. The reason of this problem is that they play in the agricultural field.
In this overseas field training I investigate the residual pesticide in the soil of agricultural field. Then by using this analysis result I would evaluate the health risk on the field.
I sampled soils from 6 agricultural fields near Kasetsart University (Kamphaeng Sean Campus). In these fieldes some agricultural products are cultivated and exported. In this research I chose a pesticide, “Cypermethrin” as an analysis compound. It was reported some times that cypermethrin remained over standard in the products from Thailand. I am now analyzing them by GC/MS. The reports about this cypermethrin in Thailand crops are not published yet. I think my study is important and highly required.
Key words: Residual pesticide, agricultural area, Thailand
