Study for Determination of Heavy Metals in Fish Species of the River Yamuna (Delhi) by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES)

Indrajit Sen, Ajay Shandil and V. S. Shrivastava

The presence of heavy metals in our environment has been of great concern because of their toxicity when their concentration is more than the permissible level. These metals enter in the environment by different ways like industrial activities etc. The fish samples Rahu (Labeo rohita), Tilapia (Tilapia zilli) and Catfish (Chrysichthys nigrodigatatus) were collected from Yamuna River in Delhi. In this study we have used Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) technique for determination of Al (Aluminum), B (Boron), Ba (Barium), Cd (Cadmium), Co (Cobalt), Cr (Chromium), Cu (Copper), Fe (Iron), K (Potassium), Mg (Magnesium), Mn (Manganese), Na (Sodium), Ni (Nickel), Pb (Lead), Sb (Antimony), Sn (Tin), Si (Silicon), P (Phosphorus) and Zn (Zinc) in different species of fish like Rahu, Tilapia and Catfish. The concentrations of Ca, K, Mg, Na and P are too high as compared with other metals as these metals were not in the maximum permissible level set by World Health Organization (WHO).
