ANTHROPOCENE EFFECTS ON THE RIVER DAYA AND THE LAGOON CHILIKA BY THE EFFLUENTS OF BHUBANESWAR CITY INDIA: A PHYSICO-CHEMICAL STUDY.

Bhubaneswar city poses problems of liquid waste disposal and allow it to a natural drain (Gangua drain) to the river Daya which is the hydrographic life line of South Mahanadi delta and major fresh water source to the largest lagoon of Asia, the Chilika. Use of river water from the Daya, face the challenge of meeting compliance economically by national regulatory standards to maintain riparian rights of the people and the ecology downstream. Present study is conducted to determine the physicochemical standards and the heavy metals polluting of the river upstream, the main drain Gangua Nallah and the water quality downstream in 2017. The digital equipments are used to find the physical, biological parametric values and for heavy metals by the XRF spectrometer. The water quality parameters determined are pH, DO, BOD, COD, TDS, Ca, P, K, Ni, Ca The heavy metals and the REE?S were also determined during the flow. The result shows the water quality during non-monsoon is deteriorating matching with the Anthropocene impacts. Weekly water samples were taken for the non-monsoon and monsoon to study the chemical toxicity and their impact on day to day behavior to decide the human activity and manage the brain chemistry as guided by neurotransmitters. The results are compared with the previous studies made CPCB and other researchers.
