Abstract

The present study investigated the concentration of heavy metals (lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), zinc (Zn), and iron (Fe) in water, sediments, Chrysichthys nigrodigitatus and Macrobrachium macrobrachion from Badagry Creek and Ologe Lagoon, between June and November, 2016. Water, sediment, 90 C. nigrodigitatus and 110 M. macrobrachion were collected and digested using standard method. Fe (178.97±15.48mgL -1 ) and Zn (299.63±152.17mgL -1 ) concentrations in water of Ologe Lagoon was higher (p<0.05) than that recorded in Badagry Creek (138.16±39.49 mgL -1, 295.71±9.33 mgL -1 ). Cd concentration in sediment from Badagry Creek (7.96±4.45µgg -1 ) was significantly (p<0.05) higher than that from Ologe Lagoon (5.98±2.48 µgg exceeded WHO permissible limits. The results indicated that both water bodies are contaminated with heavy metals although more prominent in Ologe Lagoon. Therefore, indiscriminate discharging of untreated effluents into Badagry creek and Ologe Lagoon should be cautioned.

尼日利亚badagry小溪和ologe泻湖水柱、沉积物、黑颡鱼(银鲶鱼)和巨臂虾(咸淡水对虾)中重金属的比较浓度

研究了2016年6月至11月巴达格里河和奥罗格泻湖水体、沉积物、黑digitatus和Macrobrachium中重金属铅(Pb)、镉(Cd)、铬(Cr)、铜(Cu)、锌(Zn)和铁(Fe)的浓度。收集水、沉积物、90只黑尾海螺和110只大臂海螺，采用标准方法消化。Ologe Lagoon水体Fe(178.97±15.48mgL -1)、Zn(299.63±152.17mgL -1)浓度高于Badagry Creek水体(138.16±39.49 mgL -1、295.71±9.33 mgL -1) (p<0.05)。Badagry Creek沉积物中Cd的浓度(7.96±4.45µgg -1)显著高于Ologe Lagoon沉积物中Cd的浓度(5.98±2.48µgg)，超过WHO的允许限量(p<0.05)。结果表明，两种水体均存在重金属污染，但以奥罗格湖较为突出。因此，不加区分地将未经处理的污水排放到Badagry小溪和Ologe泻湖应该谨慎。
