| Abstract | Agricultural activities on the floating gardens are likely the main source for the contaminationthat appears to impact the Inle lake ecosystem. This study investigated the nutrient accumulationsin water and the pesticide residues from water, sediment, tomato fruits as affected by Good Agricultural Practices (GAP) and non-GAP on floating beds (hydroponic cultivation techniques) grown in the mesocosm. This trial was conducted at Yezin Agricultural University (Phyu campus), Myanmar during the wet season of 2020. All data were analyzed using Student's t-test. The results found that total nitrogen, phosphorus, potassium and organic carbon in water were greater accumulated in non-GAP than GAP. The water quality index showed that non-GAP was threatened to the water body. In tomato fruit, four residual pesticides were detected in non-GAP while only one was found in GAP. The residual detection of pesticide in the surface water and sediment showed that the non-GAP farm had higher degree and amount of pesticide residues than the GAP areas. This indicated that poor management of fertilizers and pesticides usage has had a negative effect on the environments. It could be concluded that GAP was environmentally friendly, but non-GAP was intended more impact on environment. Environmental risk assessment implies establishing a management strategy that aims at reducing or minimizing the impact of agrochemicals under agricultural production. |
