摘要
本研究涉及对沃尔特湖选定的网箱养鱼场的水柱和底部沉积物中的沉积物质量和重金属进行测定，以评估网箱养鱼对湖泊造成的金属和有机物污染的潜在影响。沉积物分析表明，所有采样点的质地均为砂质粘壤土，以沙为主，范围为31.5%~81.2%。有机质（TOM）范围为4.42%~8.89%，有机碳（TOC）范围为2.57%~5.22%。总氮（TN）在0.22%~0.45%之间波动；总磷含量在0.22%至5.30%之间。农场沉积物中的 TOC、TOM 和 TN 含量显着低于参考地点（ANOVA，p .05). Lead, copper, cadmium and selenium were not detected in the water. The results revealed that heavy metal concentrations in the water column and sediments were low and within tolerable levels, indicating no influence of metals from fish feed was observed on the lake water quality. However, the farm seemed to have moderate impact on sediment quality from organic matter. Water and sediment quality monitoring should be embarked upon periodically to ensure sustainable cage culture in the Lake Volta.
