Abstract

Zn accumulation may be utilized as a reliable biomarker for determining the degree of environmental pollution in water, sediment, and river fish tissues. In this study data obtained from ICP-MS evaluation revealed that the levels of Zn in the sediment from 9 hotspots (HS) were: 214.5, 138.8, 164.8, 269.6, 156.6, 356.6, 120.8, 387.5, and 259.7 mg/kg dry mass of sediment, respectively. Zn concentrations in S. cephalus fish liver at 9 hotspots were as follows: 11.623, 9.982, 13.514, 31.451, 27.513, 39.791, 10.034, 46.502, and 14.903 mg/kg wet weight. Only in the HS-8 the Zn concentration in the liver exceed the FAO limits. Zn concentrations in muscle varied from HS-1 to HS-9: 3.013; 7,021; 3,304; 6,513; 5,504; 2,802; 5,213; 6.342; and 8.704 mg/ kg wet weight. The Zn concentrations in muscle did not surpass FAO guidelines and do not constitute a concern to public health. There is a statistical relationship between Zn concentration in sediment and the liver. The Zn level found in the sediment at each of the nine sampling locations, reveals heavy pollution caused by industry or other activities conducted in these locations and needs more seriousattention from authorities.

锌对环境的污染及其进入食物链的风险

锌积累可以作为一种可靠的生物标志物，用于确定水、沉积物和河流鱼类组织的环境污染程度。ICP-MS测定结果显示，9个热点地区(HS)沉积物Zn含量分别为:214.5、138.8、164.8、269.6、156.6、356.6、120.8、387.5和259.7 mg/kg干质量。9个热点地区头鱼肝脏锌含量分别为11.623、9.982、13.514、31.451、27.513、39.791、10.034、46.502和14.903 mg/kg湿重。只有HS-8中肝脏锌浓度超过FAO限值。肌肉中锌含量HS-1 ~ HS-9: 3.013;7021;3304;6513;5504;2802;5213;6.342;8.704 mg/ kg湿重。肌肉中的锌浓度没有超过粮农组织的指导方针，也不构成对公共卫生的关切。沉积物中锌浓度与肝脏有统计学关系。在9个采样点的沉积物中发现的锌水平表明，在这些地点进行的工业或其他活动造成了严重污染，需要当局更加重视。
