Abstract

Current study was conducted to analyze the water in the area of Sahiwal district for toxic metals. This study gives information about the concentrations of three toxic metals, arsenic (As), lead (Pb) and chromium Cr(III). Total of 20 samples were collected, including tap, filter plant, hand pump and tubewell water. The levels of As(III) and Cr(VI) were determined using spectrophotometer while Astotal, Crtotal and Pb concentrations were analysed by using inductively coupled plasma-mass spectrometry (ICP-MS). The results of chromium were above EPA recommended value (0.05 ppm) in all the samples. On the other hand, the concentrations of arsenic and lead were lower than Pak-EPA Standard limits. The mean level of chromium was 5.559 mg/L which was 111.18 times higher than WHO and local standard of 0.05 mg/L. Similarly, the mean level of arsenic and lead were 10.668 µg/L and 7.037 µg/L, respectively, which were 4.687 and 7.1053 times, respectively lower than Pak-EPA Standard value of 50 µg/L.
