Abstract

The article examines the impact of intensive and anthropogenic impacts on the ecological status of sur-face water in Hanoi city. The results of instrumental studies of water pollution in many water bodies in the river Tolich — the main river of Hanoi, captital of Vietnam. In Hanoi surface water is heavily polluted, due to rapid industrialization, high population density, deterioration of infrastructure, outdated technologies of urban sewage treatment plants. The main pollution in water received through the network and a direct relief to the urban areas. The data on the devices and methods of assessing the quantitative and qualitative composition of water of river Tolich. The main sources of dangerous pollution are ammonium nitrogen (more than 50 times MPC), petroleum products (more than 20 times MPC), phosphates (10 times MPC) and other substances. Presents data on the quantitative composition of impurities in different branches of industry. The conclusion about the need to create and maintain the state monitoring of the water environment and coastal zones.
