Estimation of chromium and copper in chicken liver samples by Inductively Coupled plasma–Optical Emission Spectrometry method
Due to food safety issues and human health risk, heavy metal concentration through food chain is a concerned problem worldwide. There are several reports on transfer of non-biodegradable heavy metals from soil to animals by direct contamination or through feed. Hence, the present study was undertaken to estimate the presence of heavy metals chromium and copper in chicken liver samples (n=54) which were collected in and around Tirupati region of Andhra Pradesh, India. These samples were analyzed for the presence of chromium and copper by using Inductively Coupled Plasma–Optical Emission Spectrometer (ICP-OES). The excess levels of chromium considered to be carcinogenic and copper leads to tissue injury. The results of this study revealed that the range of chromium is between 0.009 to 0.091ppm and for Copper is 0.006 to 2.54 ppm in chicken liver samples which is not significant and within prescribed tolerance limit.
