Research on pollution of Sterols in Kimnguu River water, Hanoi

Abstract

As the world\'s population continues to grow, water pollution is one of the greatest challenges worldwide. More wastewater is produced and the demand for clean water is increasing. Make sure Human and environmental safety and health, efficient wastewater treatment systems. And there is a need for reliable assessments of water quality and pollution. Sterols are a group of compounds that indicate water pollution. Sterols are often present in high concentrations in untreated domestic wastewater and they have a high potential for bioaccumulation in sediments. Sterols have been extensively studied in surface water, wastewater before and after treatment systems, and sediments. In particular, coprostanol is an indicator of waste contamination (human and animal feces) in the environment, and analysis of the ratio of coprostanol/cholesterol indicates the source of sterols in wastewater. Kim Nguu River is Hanoi\'s wastewater drainage river, the composition of pollutants in the river is quite complicated, the study of sterol pollution in river water can help to learn more about the origin of pollutants in the water.
