ABSTRACT

Urban effluents may contain several cytotoxic contaminants that are dumped into rivers, causing environmental degradation in downstream reaches. Rivers in Pune (Maharashtra) are the most polluted water bodies because of their function in transporting waste from municipalities and industries as well as run-off from agricultural fields in their basin. Despite different restrictions and regulations, a variety of small-scale companies discharge their trash directly into the river. The current work employed an Allium cepa bioassay to assess cell toxicity by water samples collected from polluted bodies of water in Pune as a result of industrial effluent. The study was carried out by collecting wastewater samples from three sampling sites (Site A - Bhima River, Site B - Pavna River, and Site C - Indrayani River) and investigating their physicochemical properties. Tap water was used as a control in every case. The water quality of the samples was evaluated using a TDS meter (Total Dissolved Solids). Water cytotoxicity was assessed using the Allium cepa bioassay. The study's findings revealed that A. cepa bulbs exposed to Indrayani River water had a considerable reduction in MI, followed by Pavna and Bhima River water. The Indrayani and Pavna Rivers frequently get a higher volume of domestic and industrial sewage from several municipalities than the Bhima River. The findings of this investigation reveal that the river water pollutants comprised several toxic compounds that are harmful to the aquatic environment and human health.
