Zanna *,穆斯塔法LM, Faruk乌斯曼,穆罕默德碱,Yahuza M萨尼,比罗YK本研究涉及一些有毒的量化和基本金属。锌、铅、锰、铜、镍、和Cd在水中,鱼和沉积物样品来自Jakara大坝,Minjibir,卡诺。水样收集使用低于4升的塑料容器表面指定点。沉积物样品的收集使用不锈钢钻五(5)点随机采取和同质化在清洁塑料水桶和风干然后用2毫米孔渗。鱼类罗非鱼,猫和肺购买鱼渔民的坝址在每个访问。样本分别消化用王水在100˚C三个小时。结果表明,罗非鱼,猫和鱼有最高水平的基本金属而肺鱼有毒金属的最高水平。水样本比沉积金属的最高水平。水样的金属浓度在这个订单0.773±0.546 > 0.0585±0.0414 > 0.0364±0.0257 > 0.0230±0.0162 > 0.0126±0.0089 > 0.0138±0.0098虽然沉积物样品金属浓度在这个订单1454.16±0.0411 > 966.66±0.0227 > 674.72±0.0190 > 576.66±0.0163 > 187.07±10.018 > 0.1233±0.0087。猫的鱼鳃的浓度在订单7633.25±0.145 > 966.67±0.0195 > 606.67±0.0313 > 378.32±0.0151 > 352.5±0.0871 > 341.67±0.0051。 Bones of cat fish have metals concentration in this order of 3050 ± 0.0643>785.82 ± 0.0224>339.17 ± 0.0135>0.305 ± 0.201>0.0386 ± 0.0156>0.0136 ± 0.0052. While flesh of cat fish have metals concentration in this order 6799.17 ± 0.137>1808.32 ± 0.0269>492.50 ± 0.145>473.32 ± 0.010>400 ± 0.0032>25.08 ± 0.0010. In tilapia fish gills metals concentration are in the order of 6822.5 ± 0.147>4108.32 ± 0.094>1800.32 ± 0.0621>668.32 ± 0.0267>590 ± 0.0175>400 ± 0.00670. The bones of tilapia fish have metals concentration in the order 8108.32 ± 0.168>2058.32 ± 0.0461>Pb>Mn>Ni>Cd while flesh have metals in the order of Zn>Cu>Mn>Pb>Ni>Cd. Lung fish have metals in the order of Cu>Zn>Mn>Cd>Pb> Ni. Tilapia and cat fish have highest levels of essential metals and which is good for human consumption and within the permissible heavy metals for human consumption set by FAO/WHO Recommendation were exceeded in the edible portions. All the elements are above FOA/WHO recommendation.
