“…Range of recommended standard permissible limits of metals such as zinc ,lead , copper ,iron, cadmium and chromium, in fish has been documented (WHO 2003). The present findings as regard metal concentration in fish is similar to the record of metals in C. nigrodigitatus from Ibaka and Ifiayong fishing sites in Akwa Ibom State, Nigeria (Akpanyung et al 2014) but exceeded that which was recorded in E. fimbriata from Cross River Estuary (Udo and Ndunobong 2016). However, all the metals obtained in fish during this study was lower than that reported in Clarias gariepinus and Oreochromis niloticus (Ejike and Liman 2017).…”

An investigation was made from April to September 2018 to detect some metals (cadmium, chromium, copper, iron, lead and zinc) in the fishes like Kribia nana, Chrysichthys filamentosus and Pegusa lascaris, as well as in water and sediment from three creeks i.e. Badagry (Station 1), Tomaro (Station 2) and Ajegunle (Station 3) in Lagos, Nigeria. Samples were collected and analyzed according to standard methods. Most of the water quality parameters are within standard recommended limits. Iron content in C. filamentosus (11.57±2.50mg/kg) from station 3 was higher (p<0.05) than iron content from station 2 (6.54±2.88mg/kg), while iron content in K. nana (8.34±1.10mg/kg) from station 3 was higher (p<0.05) than that from station 1 (6.12±1.04mg/kg) and station 2 (3.62±1.14mg/kg) respectively. Zinc (5.54±1.12mg/kg) recorded from station 3 was significantly (p<0.05) higher than that from station 2 (2.45±0.96mg/kg) and station 1 (3.84±0.86mg/kg). Iron content in all the fishes, cadmium in C. filamentosus and lead, chromium, copper in K. nana in stations 1 and 3 exceeded permissible limits. Condition factor (K) of most fish species was greater than 1. The Hazardous Index (HI) content in C. filamentosus from the three creeks and K. nana from stations 1 and 3 was above 1. Ecological risk factor(Er), enrichment factors (EF) and Index of geo-accumulation indicated moderate contamination of the sediment with cadmium. In conclusion, the three creeks are moderately polluted with metals but consumption of large quantity of the fish species could have high health risk. Hence, discharge of untreated metals into the water should be precluded.

“…Similar concentrations of some heavy metals that exceeded the limit in Chrysichthys nigrodigitatus from Ibaka and Ifiayong fishing sites in Akwa Ibom State has been reported [4]. The values of Pb, Cr, Zn and Cd in this study was higher than that recorded in E. fimbriata from Cross River Estuary [10]. But the values were lower than that reported in Pseudotolithus senegalensis and E. fimbriata from Carter Bridge River and Makoko River in Lagos, Nigeria [43].…”

“…The parameters (except alkalinity, hardness, BOD, conductivity and COD) in this study were higher than that reported in Badagry creek [19]. It was also higher than that reported in Cross River Estuary, in Ogbe creek, in Tomaro creek, Tidal creek and from Asejire Lake respectively [10,[20][21][22][23]. On the other hand, the values of phosphate, hardness, salinity and TDS in this study were lower than that recorded in Majidun River in Lagos, Nigeria [24].…”

The status of Agboju, Ajegunle, Topo and Gbaji water bodies in Badagry Division of Lagos State, Nigeria was evaluated between April and November 2018 in order to determine the suitability of the ecosystem to biota and safety of the aquatic resources for human consumption. Some environmental variables such as alkalinity, temperature, biochemical oxygen demand (BOD), conductivity, total dissolved solid (TDS), carbon (iv) oxide (CO 2), total hardness, chemical oxygen demand (COD), turbidity, phosphate, dissolved oxygen (DO), pH, salinity, sulphate and nitrate, and some heavy metals (Fe, Cu, Zn, Pb, Cd and Cr) in water, sediment, aquatic plant (Eichhornia crassipes) and fish (Ethmalosa fimbriata) were measured using standard procedures. The results showed that BOD, COD, total hardness and turbidity values were above the standard permissible limits. Cd in water column of Agboju and Ajegunle, and Pb recorded from Agboju, Ajegunle and Topo, exceeded standard permissible limit. Cu (0.56±0.54), Zn (5.45±0.89), Pb (0.54±0.47) and Cr (0.455±0.375) contents in E. fimbriata (from Ajegunle) was slightly above permissible limits while Cd and Fe contents in the fish across the four stations were above permissible limits. Contamination factor, Index of geochemical accumulation and enrichment factor showed moderate degree of contamination of cadmium and Fe in the sediment. This preliminary study could be concluded that the biota can still survive in the ecosystems despite high contamination of the water bodies with metals. However, human consumption of several of E. fimbriata and water could cause health hazard. Therefore, urgent effort should be made by all users of the ecosystem to decline in discharging untreated waste into these water bodies.
