“…These values were in accordance with the standard levels for drinking water in the absence of distribution systems (6.5 < pH < 8.5; [21]). However, these recorded pH values were lower when comparing to other studies [22,23]. The pH value at Turnasuyu Creek, which has an alkaline character, were measured between 7.0 and 9.0 during the study [22].…”

Aims: The purpose of this study was to assess the status of the heavy metals As, Cd, Pb, Mn and Zn in the surface water of the Sub-catchment Barrage of Tougou for which water comes mainly from agricultural activities. Place and Duration of Study: A total of 73 water samples were taken at the inflow of the water body and at several points located on the water body, from August to October 2019. Methodology: Water samples were characterized for temperature, pH, electrical conductivity (EC), sulfate (SO42-), nitrate (NO3-) and phosphate (PO43-). Heavy metals were analyzed using a microwave plasma atomic emission spectrometer (MP-AES), Agilent Model 4210. Results: The EC range was between 27.45 and 53.90 µS/cm with an average pH of 6.4. Nitrate (NO3-) was the most abundant anion in the water (39.70 mg / L) and phosphates (PO43-) were present in very small quantities (0.34 mg / L). The results showed very low concentrations of Pb and Cd, below 5 µg / L and below 2 µg / L, respectively. The concentrations of As, Mn and Zn in the water were 2.8 µg / L, 13.2 µg / L and 9.8 µg / L, respectively. Agricultural practices do not have a significant effect on surface waters. The concentrations of heavy metals analyzed in the water were lower than the standards established by the World Health Organization for drinking water quality. Conclusion: This information, certainly important, does not allow us to conclude on the risk of the consumption of this water on human health. Further studies should be conducted on this water body to evaluate the potential risk for public health and to examine the concentrations of heavy metals in the sediments, because it is known that sediments have a high absorption capacity for heavy metals and are then considered the main target for water purification related to heavy metals.

In recent years, there has been an increasing ecological and global public health concern associated with environmental contamination by heavy metals on groundwater resources especially in the developing countries. Hence, this study assessed the impacts of industrialization on the quality of groundwater in Shagamu and Ota industrial areas of Ogun State, Nigeria between the period of July and December 2018, covering both wet and dry season. A total of 80 samples was collected from the industrial areas while a total of four control samples was also collected from the residential areas of the study locations across both wet and dry season using a random sampling technique. The water samples were then analyzed in the laboratory for their physico-chemical parameters (using standard procedures) and heavy metals using the Atomic Absorption Spectrophotometer (AAS). The results were evaluated for descriptive and inferential statistics using SPSS for Windows version 20.0. The mean range of values for the measured parameters was: pH (4.35–9.42), EC (18.50–684.0 μScm −1 ), hardness (3.83–396.06 mg/L), Ca 2+ (0.18–138.75 mg/L) and that of heavy metals concentrations in the water sample were: Pb (0.003–0.199 mg/L), Cd (0.002–0.013 mg/L), Ni (0.004–0.259 mg/L), Cr (0.002–0.54 mg/L), Mn (0.015–1.940 mg/L), Fe (0.02–2.01 mg/L), Cu (0.012–0.72 mg/L), Zn (0.004–0.500 mg/L). A comparison of the obtained results with the World Health Organization standards (for drinking water) revealed that the levels of pH, Ca, Pb, Ni, Mn, Fe, Cd, and Cr were higher than the prescribed values. It was observed that groundwater sources for the dry season in both Ota and Shagamu have higher heavy metal concentrations that are above the permissible limits than the wet season, implying that more industrial activities were probably conducted during the dry season under the sampling period. The result of the heavy metals was in the magnitude according to the trend Fe > Mn > Cu > Cr > Zn > Ni > Pb > Cd. This study revealed that these industrialized areas contained high concentrations of heavy metals which can cause health disorders and behavioral defects. Thus, the water in the study locations is not suitable for consumption without prior treatment. It is therefore, recommends that the water in the study locations should be treated before were used for various domestic purposes, and the construction of the boreholes and dug wells are proposed here to follow proper siting regulations.

Özet: Bu çalışmada Karacabey (Bursa) ilçesi ve çevresinde yeraltısularının hidrojeokimyasal özellikleri incelenmiş ve sağlık risk değerlendirmesi yapılmıştır. İnceleme alanında yeraltısularının Ca-HCO3, Ca-Mg-HCO3 ve Mg-Ca-HCO3'lı sular fasiyesinde olduğu tespit edilmiştir. Mg artışı formasyonlar içerisindeki kumtaşı ve konglomera seviyeleri ile kaya-su etkileşiminden kaynaklanmaktadır. İnceleme alanında suların genel olarak fiziksel özellikleri ve anyon-katyon içerikleri açısından içme suyu sınır değerlerini aşmadığı tespit edilmiştir. Ancak, yeraltısularının As içeriği 9-79.1 µg/l arasında değişmektedir. As artışı genelde volkanik kayaçlarla ilişkili olarak jeojenik kökenlidir. Bazı lokasyonlarda NO3, Fe ve Mn içeriklerinin de içme suyu standart değerlerinin üzerinde olduğu tespit edilmiştir. Bu artışların jeojenik ve antropojenik kökenli olduğu düşünülmektedir. Çalışmada içme suyu sınır değerlerini aşan As, NO3, Fe ve Mn parametreleri için sağlık risk değerlendirmesi yapılmıştır. Su kaynaklarının oral (içme) ve dermal (deri) yolla alım ile gerçekleşebilecek tehlike katsayıları (HQ), tehlike endeksi (HI) ve kanser riski değerleri yetişkin ve çocuk bireyler dikkate alınarak hesaplanmıştır. Su kaynaklarının içmesuyu olarak uzun süreli kullanımında sağlık için olumsuz etki oluşabileceği tespit edilmiştir. As elementi açısından kanser riski olasılığı da bulunmaktadır.Abstract: In this study, the hydrogeochemical properties of the groundwater samples in the Karacabey (Bursa) district and surrounding were investigated and health risk assessment was performed. Groundwaters are Ca-HCO3, Ca-Mg-HCO3 and Mg-Ca-HCO3 facies. The increase of Mg is originated from water-rock interaction related to sandstone and conglomerate levels in different formations. In the study area, it is observed that the waters do not exceed the drinking water limit values in terms of physical properties and anion-cation contents. However, the As content of groundwater ranges between 9-79.1 µg/l. The increase of As is geogenic origin associated with volcanic rocks. In some locations, NO3, Fe and Mn contents were found to be higher than the drinking water standard values. These increases are thought to be of geogenic and anthropogenic origin. In this study, health risk assessment was made for As, NO3, Fe and Mn parameters which exceed drinking water limit values. Hazard Quotient (HQ), Hazard Index (HI) and Carcinogenic risk values of the spring waters for oral (drinking) and dermal (skin) intake were calculated by taking into consideration adult and child individuals. It has been determined that the long-term use of water resources as drinking water may have a negative impact on health. The carcinogenic risk may also be caused by the As element.
