ABSTRACT

Asian countries are the chief in the production of rice clerical for regarding 90 percent of the world's production. More than 75percent of the world supply is absorb by population in Asian countries and consequently rice is of colossal magnitude to food defense of Asia. As a result the current research work proves the cause and modern status of heavy metal contamination of paddy lands in the surrounding Tirupati industrial areas and around chittoor district. A trouble free two stride microwave assisted digestion method was developed for the concurrent fortitude of seven elements of total heavy metals Cr, Ni, As, Se, Cd, Hg and Pb in rice samples by means of inductively coupled plasma mass spectrometry (ICP-MS). Approximately 0.3 grams of rice sample was originally digested by the use of a concoction of acids. The current revise was conducted to quantify the concentrations of heavy metals like chromium (Cr), nickel (Ni), arsenic (As), Selenium (Se), cadmium (Cd), Mercury (Hg) and lead (Pb) in locally cultivated rice and their probable human being health risks in the areas of surrounding Tirupati and around chittoor district is to be analyzed by means of the technique inductively coupled plasma mass spectroscopy (ICP-MS). Most importantly, a greater number of our explorations confirmed that the metal contents in rice grains were lower than the permissible limits which was confirmed by various standards, are Codex recommendations of joint Food and Agriculture Organization/ (WHO) World Health Organization Food Standards Program me and/or (FAO) food regulations imposed by the respective governments and compared with those obtained with the developed literature values. Thus it is harmless for consumption. From the present study, it is unambiguous that there is no prospective peril to the local inhabitants of these four sampling areas by consumption of rice.
