“…However, water sources are often contaminated. Contamination of water sources can emerge from leaching of rocks, industrial and agrochemical discharges that are washed into them (Lawal and Lohdip, 2011), especially during the rainy season (Obaroh et al, 2015). These contaminations can affect the clarity and the chemical constituents of the water source.…”

Boreholes and hand dug wells from Bantaji and Rafin-Kada settlements of Wukari L.G.A. were analyzed for fourteen physicochemical parameters and seven heavy metals collected within July, 2015 to March, 2016 using standard methods. The mean difference in concentration of dissolved oxygen between the wet and dry seasons in the Bantaji boreholes was statistically significant at p<0.05. In addition, the electrical conductivity, nitrate nitrogen, phosphate and dissolved oxygen concentration were also statistically significant in the Rafin-Kada Boreholes. For the well water samples, total dissolved solids (TDS), nitrate nitrogen and chlorides were also statistically significant between the wet and dry seasons of the Bantaji wells while in the Rafin-Kada wells, with only dissolved oxygen having mean concentration that was statistically significant at p<0.05. All the physicochemical parameters in the boreholes and hand dug wells fall within the Nigerian Standards for Drinking Water Quality (NSDWQ) acceptable limits. The heavy metals, Pb and Mn had mean concentrations in the wet and dry seasons that were statistically significant in the Bantaji borehole, Bantaji well and Rafin-Kada borehole while Rafin-Kada borehole had statistically significant mean concentrations of Cd, As and Mn at p<0.05. All the heavy metals analyzed fall within the NSDWQ acceptable limits except Pb which had higher mean concentrations in the wet and dry seasons than the acceptable limits from Rafin-Kada wells (

“…There were differences between all the years, and these differences were found to be statistically significant (p<0.05) (see Figure 3). The average zinc metal level was reported to be 5.00 µg/l, 20 µg/l in the San Andres Lagoon, Argungu rivers (Va´zquez-Sauceda et al 2011;Obaroh et al 2015). According to WHO (1993), Standard value of zinc in water is 3000 µg/l.…”

This study has been conducted to find out the heavy metal pollution of Büyük Menderes River in Aydın. Water samples having been taken from 8 stations of the Buyuk Menderes for 13 years were examined in terms of Cu, Zn, Mn, Pb, Cd and Fe. The values were measured as the lowest in the Yenipazar Bridge (10.02±9.86) and the highest in the Sarayköy Bridge (18.46±17.48) for copper; the lowest in the Aydın Bridge (32.07±18.14) and the highest in the Sarayköy Regulator (65.19±55.54) for zinc; the lowest in the Adıgüzel Dam (41.61±35.38) and the highest in the Sarayköy Regulator (148.36±105.02) for manganese; the lowest in the Adıgüzel Dam (4.01±3.96) and the highest in the Yenipazar Bridge (9.95±8.62) for lead; the lowest in the Söke Regulator (2.37±2.18) and the highest in the Sarayköy Bridge (2.61±2.18) for cadmium; the lowest in the Adıgüzel Dam (77.21±72.47) and the highest in the Söke Regulator (330.07±306.24) for iron. Finally, it has been observed that Büyük Menderes River is not under the threat of pollution.

“…Higher levels of Pb have been reported in surface water in Nigeria, exceeding water quality criteria for aquatic life. 23 – 25 Lead levels in these surface water bodies may pose both acute and chronic toxicity to the aquatic organisms, thereby putting the ecosystem at risk. Furthermore, significant numbers of the Nigerian population, especially rural dwellers, depends on surface water for direct use for domestic activities, including cooking.…”

Background. As resources become scarce, information from material and substance flow analysis can help to improve material recovery policy. The flow of toxic substances such as lead (Pb), cadmium (Cd), chromium (Cr), arsenic (As) and antimony (Sb) can be used as a basis for appropriate risk management decisions for optimum environmental quality. Objectives. The present study examined a material and substance flow analysis of used lead acid batteries (ULAB) from motor vehicles and implications for environmental quality in Nigeria. Methods. Information on motor vehicle imports was obtained from the literature. Mathematical models were constructed and used for the material and substance flow analysis. Samples of 50 brands of ULAB pastes were digested using a microwave digestion system followed by elemental determination (Pb, Cd, silver (Ag), As, cobalt (Co), calcium (Ca), Cr, copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), Sb, selenium (Se), and tellurium (Te)) with inductively coupled plasma optical emission spectroscopy. Results. Approximately 4.8 million tons (Mt) lead acid batteries (LAB) from vehicles was used in Nigeria between 1980 and 2014, out of which approximately 2.6 Mt had reached end-of-life (EoL) stages. From the total amount in EoL, approximately 2.3 Mt was recycled, and 0.3 Mt was landfilled. Among the toxic elements, Pb, Cd and As were the most abundant in ULAB; and of the valuable elements, Fe and Cu had the highest levels. Approximately 3.5 Mt of Pb was used in the past (1980–2014) in ULAB for motor vehicles, out of which approximately 1.9 Mt tons was in EoL stages. Discussion. The results revealed that the battery pastes were heterogeneous. Only Pb exceeded the total threshold limit concentration (TTLC) of 1000 mg/kg. The TTLC describes the safe levels or concentration of heavy metals in the environment. The levels observed for other metals in this study were below the TTLC values. The present study estimated an average life span for lead acid batteries in motor vehicles in Nigeria of 5 years, suggesting an additional 2.2 Mt at EoL by 2019. High concentrations of Pb in air, water and soil carry the potential for contamination of food products, especially in Nigeria, where food is traditionally prepared and sold in open air markets in an unregulated manner. Conclusions. High amounts of toxic elements present in the various life cycle stages signal potential environmental and human health hazards. Competing Interests. The authors declare no competing financial interests.
