This study aimed to detect and quantify trace metals (chromium, zinc, and manganese) in drinking water samples from five different brands using UV spectroscopy and atomic absorption spectrophotometry (AAS). Trace amounts of these metals are essential for human health, ecosystems, and the environment; however, excessive concentrations can lead to severe health complications. UV spectroscopy analysis revealed chromium concentrations ranging from 0.015 ppm (S1) to 0.044 ppm (S4), zinc concentrations from 0.0951 ppm (S1) to 0.1829 ppm (S2), and manganese concentrations from 0.015 ppm (S1) to 0.044 ppm (S4). AAS analysis further confirmed the presence of these metals, with manganese levels ranging from 0.014 ppm (S5) to 0.040 ppm (S3), chromium levels from 0.014 ppm (S5) to 0.040 ppm (S3), and zinc levels from 0.0780 ppm (S5) to 0.1834 ppm (S2).
While trace metals are vital for living organisms in minimal amounts, concentrations exceeding permissible limits pose significant health risks. Excessive chromium exposure can cause skin rashes, respiratory issues, lung cancer, and even death. High manganese levels are linked to fatness, glucose intolerance, and blood clotting, while elevated zinc concentrations may damage the pancreas, disrupt protein metabolism, and contribute to arteriosclerosis. Prolonged exposure to zinc chloride can also lead to respiratory disorders.
The findings emphasize the importance of monitoring trace metal concentrations in drinking water to ensure compliance with safety standards and mitigate potential health risks. This study highlights the need for stringent quality control measures in the production and distribution of drinking water to safeguard public health.
