| Research Abstract |
We were investigated following the effects of environmental pollution caused by agriculture and ecosystems to large-scale irrigation at Amu-Darya river basin in Uzbekistan, 1) Central Asia. It was researched of drinking water. 2) We collected Irrigation water and drainage water, and river water. There were investigated the effects of them by irrigated agriculture. 3) In the Nukus region, we were interviewed about the impact of the human body. 4) We collected water samples from river and groundwater one time of every month.
As a result, all ions concentrations of groundwater were higher than river water. In addition, in winter time, especially, nitrate concentration in groundwater is high than other seasons. Toxic substances which were dissolved the enamel of teeth in children were observed in rural areas of Nukus district. Toxic substances may be, included in the well water. However, the changes of ion concentrations were different on every year. There is a need to examine in more detail was revealed.
