Assessment of cadmium (Cd) and chromium (Cr) contamination in vegetables sold in local markets of Bangalore city, Karnataka, India
Keywords:bioaccumulation, cadmium, chromium, heavy metals, health hazard
The study was focused on the concentration of Cadmium (Cd) and Chromium (Cr) contamination in vegetables that sold in local markets of Bangalore city. In this study we used the vegetables and green leafy vegetables such as cabbage, cucumber, cauliflower, green chilli, coriander, spinach. The accumulation of heavy metal was detected by using Atomic Absorption Spectrophotometry (AAS). The obtained results were showed that the concentration of Cadmium and Chromium were slightly exceeding the recommended maximum acceptable limits. The overall study concludes that the atmospheric deposition, untreated sewage water and poor unhygienic marketing systems were plays a main role in elevating the levels of Cadmium (Cd) and Chromium (Cr) in vegetables and green leafy vegetables.
