Abstract: Coal gangue is the solid waste material in the process of coal mining and coal washing, which contains a lot of heavy metal: Manganese (Mn), which poses a serious threat to food security and human health. In order to study the present pollution situation of Mn and the deposition of Mn in the tissues of fish from gangue polluted water of Yongcheng, Shangqiu, Mn was determined by using the flame atomic absorption method. The results show that the concentration of Mn in the heart, hepatopancreas, gills, muscles of crucian carp from pollution-free waters in Tianmu Lake were 138.96.±35.85 (μg/g ), 10.20±4.92 (μg/g), 30.02±7.62 (μg/g), 14.64±4.06(μg/g); whereas they were 316.48±23.41 (μg/g ), 25.84±6.03 (μg/g), 70.18±14.67 (μg/g), 30.09±10.44(μg/g) in the crucian carp from the coal mining subsidence area. The Mn deposits were all significantly higher than natural pollution-free waters. The sedimentary rule of Mn in the crucian carp is: heart > gill > hepatopancreas and muscles. The concentration of Mn in heart is significantly higher than in the other tissue. So, we draw a conclusion that coal gangue pollution aggravates the deposition of Mn in the tissues of crucian carp and it is more likely to deposit in the heart of the crucian carp. Meat from fishes of coal gangue cannot be eaten exceeding 333g per day.
