| Abstract | This research, aims to study the role of GAP (Good Agricultural Practices) on reducing the health impact from pesticide risk on farmers. The commercial vegetables growing village in Mueang district, Khon Kaen province was chosen to conduct this study. Farmers in the samevillage were divided into two groups, i.e. farmers who participated in GAP program and thosewho did not (non-GAP). Ten farmers in each group were purposively selected. Data werecollected by surveying, interviewing and laboratory analysis. Pesticide risk in soil was assessedby Hazard Index (HI). A total of 20 soil samples of Chinese kale plots, 10 each from GAP andNon-GAP plots were analyzed for the presence of 152 pesticides using QuEChERSmulti-residue extraction, followed by LC-MS/MS. They were taken at harvesting stage fromMarch to May of 2018. The results showed that pesticide residues were found in all 20 soilsamples taken from both GAP and non-GAP plots. From GAP plots residues of 7 pesticideswere found. They were alachlor, carbosulfan, chlorantraniliprole, cypermethrin, imidacloprid,metalaxyl and profenofos. From non-GAP plots residues of 14 pesticides were found. Theywere acetamiprid, acetochlor, alachlor, carbaryl, carbosulfan, chlofenapyr, chlorofraniliprole,chlorpyrifos, cypermethrin, dinotefuran, imidacloprid, indoxacarb, profenofos and tofenpyred.Assessment of health risk in terms of HI showed that, the average HI of GAP farmer was0.36 x 10-4 , and of non-GAP farmer was 2.02 x 10-4. HI values in both groups were less than1 which were considered acceptable for health risk. However, frequencies of detected pesticidesin soil of non-GAP plots were found higher than those of GAP plots. This indicated thatnon-GAP farmers were more likely to be exposed to pesticide residues from the soil than GAPfarmers. |
