IMPACT OF IDOL IMMERSION ON WATER AND SEDIMENT QUALITY IN THE RIVER MAYURAKSHI AT SAINTHIA, DIST. BIRBHUM, WEST BENGAL, INDIA

The country of India is the unique where different cultural heritage as well as festivals were found. Mainly the West Bengal state is known as various religious festivals, but Durga Puja is one of the biggest and end of this festival idol are immersed in the water bodies. Sainthia town found in the district of Birbhun, West Bengal, India which is present in the south bank of the Mayurakshi river. The idol immersion mainly effect on water as well as sediment quality of this river Mayurakshi near railway bridge at Sainthia. The study will be discussed for immersion effect of this sampling station, because in this point totally Sainthia town Durga idols were immersed. The water and sediment samples were collected at 7:30 am on 9th October 2019 during pre-immersion (before immersion) and 7:30am on 10th October 2019 during the post immersion (after immersion) in this time of periods. Mainly, the Durga idols are been made up by nonbiodegrable substances such as clay, plaster of paris, cloths, paper woods, thermocols, jutes and synthetic paints etc. these are mainly toxic substances. Over all the used materials in making of idol, the thermocol is nonbiodegradable while paints contained highly toxic heavy metals like Cr, Cd and Pb. In this study has been made to analysis the physicochemical parameters like temperature, pH, TS, TDS, TSS, EC and three heavy metals like Cr, Cd and Pb on the collected water and sediment samples of the Mayurakshi river on before and after idol immersion periods of near railway bridge sampling station. The analysed results by based on various physicochemical parameters showed that the after immersion in the river Mayurakshi increases concentration of heavy metals and changes other physicochemical parameters of the both water and sediment samples. Finally concluded that, these changes of different parameters are harmful for aquatic life and human beings as well as the level of water pollution highly increases in this Mayurakshi river. So, the huge religious activities mainly causes of the water pollution where huge disturbing aquatic ecosystem.
