Abstract：Environmental pollution can cause poisoning, disease and death of organisms, and the absorption and the accumulation of different biological tissues on pollutants are different. The absorption of heavy metal elements of various biological tissues on pollutants is an important biomedical research problem. In the present paper, a laser induced breakdown spectroscopy (LIBS) method was used to quantitatively analyze heavy metal elements in various tissues of some contaminated fish samples. Optimal experimental parameters were obtained in the LIBS experiments for these fish samples, calibration curves for plumbum and barium elements were fitted and the contents of heavy metal elements were determined with the external calibration approach. Experimental results showed that there was the heavy metal accumulation in fish liver mouth, and gills etc, however the heavy metal content in fish meat is very low. The proposed method can be used for the assessment studies of the influence of pollution on the organisms, and can be promoted in the biomedical fields.
