Abstract

This study was done to detect heavy metal traces such as Chromium, Cobalt, Nickel and Cadmium in water samples collected from different sites of Yamuna in the NCT of Delhi. The water samples were collected from Rajghat, Nigambhodh Ghat and Nizamuddin respectively. Chromium, Cobalt, Nickle and Copper were analyzed in water samples with Atomic Absorption Spectrometer. The average concentrations of Cr, Co, Ni and Cd in water samples were found 0.0073 mg/L, 0.0266 mg/L, 0.0026 mg/L, and 0.033 mg/L respectively. The concentration of Cadmiun was found higher than other three groups of metals. However, concentration of heavy metals found in the water samples of all three locations except Rajghat was within the permissible limits of World Health Orgnization (WHO) and safe to consume for irrigation. But the Cd in water sample of Rajghat was found to be ten times more than the permissible limit of WHO.
