7th International Conference on Civil Engineering for Sustainable Development (ICCESD-2024)
I am very glad to share that my first paper published on 7th International Conference on Civil Engineering for Sustainable Development (ICCESD-2024).Thanks to all my research team senior brothers and sisters who help me to do this. Specially thanks to Riyadul Hashem Riyad bhai for giving me the opportunity of doing this. Lead acid batteries comprise electrolytes, lead, lead alloy grids, lead paste, organics and plastics. These components include a significant amount of toxic, dangerous, combustible, and explosive compounds, hence posing possible risks for both human and aquatic life. The primary objective of this research is to study the hazards posed by the recycling of lead acid batteries, specifically the metal, liquid, and plastic wastes generated in the process. Twenty-one surface water samples were collected from the Bhairab, Moyur, and Rupsha rivers, with three taken at the disposal point and the remaining eighteen taken at 165-foot intervals both upstream and downstream. Distinct variations in the quality parameters of surface water samples were evident upstream, whereas downstream showed negligible fluctuations compared to the disposal points. The pH and electric conductivity (EC) were found to be 2.1, 2, and 2.3; and 3564, 3422, and 3503 µS/cm for Bhairab, Moyur, and Rupsha rivers, respectively, at the disposal points. The TDS, COD, and BOD values were significantly higher than the standard limit for all three samples at the disposal points. The lead concentrations at the disposal points of the Bhairab, Moyur, and Rupsha rivers were determined to be 0.732, 0.617, and 0.795 ppm, respectively. Disposal points show about 8 to 10 times higher lead toxicity than the far-located samples from both up and downstream. It has been demonstrated that a significant proportion of both male and female workers are dealing with hypertension-related conditions. The workers in the open market experienced a range of health conditions, including headaches (37%), colic pain (25%), nausea (14%), tremors (15%), anemia (6%), brain damage (1%), cancer (1%), and kidney damage (2%). Hence, it is imperative to enhance the recycling process of lead-acid batteries while simultaneously minimizing and closely monitoring the discharge of industrial effluents.
