A study was carried out to identify the bioaccumulation and the ascertain level of chlorinated pesticide residues in three leafy vegetables viz. red amaranth, spinach and Indian spinach collected from city market. The samples were randomly collected from different shops and analyzed by capillary column of Gas Chromatograph Mass Spectrometry (GCMS) with Electron Impact Ionization (EI) method for the detection of chlorinated pesticide. The results of the study revealed that collected samples of red amaranth and spinach were contaminated with some chlorinated substances. But Indian spinach was free of contamination with organochlorine pesticide
