Heavy Metal Contamination and Sediment Quality. In Shitalakhya River, BD

      Аннотация: Over the last few decades environment and its pollution is the governing concern for the human being in this planet. People become conscious about the changing of their surrounding global warming. But environment is degraded day by day by the weight of overcrowded people. One of such example is Shitalakhya River which encompasses eastern periphery of Dhaka city receives uncontrolled discharge of pollution, solid waste, sewage and waste water discharged from domestic, commercial and industrial activities of the city. These waste materials are tremendously deteriorating water and sediment quality of the river. The contamination level reaches at such an alarming stage during dry periods that not only the ecosystem of the river collapse but also the treatment plants of the city based on the river water virtually losses their expected quality of production. Hence the restore of the water quality of the Shitalakhya is crucial for its sustainability. This study on Shitalakhya is approaching to assess the water and sediment quality of this river which will help to establish processing plants in future for possible remedial measures to reduce water and sediment pollutions.
