In this study, it was aimed to determine the water quality of Bartın River and its usability as irrigation water. In order to evaluate the change of water quality according to the precipitation the samples were collected from 4 points in December and July months. pH, NO3, SO4, Cl-, total phosphorus, COD, SS, turbidity, some cations and metals were analyzed in the collected samples. It was determined that SS and turbidity parameters increased after precipitation and 98% of turbidity was caused by SS. Cl-, Na+, K+, Ca+2, Mg+2, SO4, TP were determined higher in the dry period. Although COD, TDS, EC, NO3 were higher in the rainy season, the difference between the two periods is not much. According to the water quality index, water quality was poor at all sampling points during the rainy season. In the dry period, good quality was also determined at only 1 sampling point. COD is the parameter with the greatest effect on effective weight and water quality. Irrigation water suitability was evaluated with the indices SAR, EC, %Na, MR, KI, PT and TH. River water is suitable as irrigation water in both periods according to SAR, %Na, MR, KI indexes. However, since the potential salinity (PS) value is greater than 3 µeq/L in the dry period, it is not suitable as irrigation water. Its total hardness value is >180 mg/L, so it is in the very hard water class.

“…However, the mean values of Cdeg of the different studied locations during the dry and wet seasons demonstrated some variations as reported by Nwankwo et al (2019). This could be credited to the disparity in the atmospheric deposition, runoff, and soil properties among the different sites investigated between the dry and wet seasons (Gunawardena et al, 2013;Biswas et al 2018;Gunes, 2022). The major contributors to the Cdeg during the dry season were Pb, Cd, and Cr while, Pb, Ni, and V were the main contributors during the wet season.…”

The impacts of oil activities and seasonal variations on the total concentrations, geochemical fractions, and human health problems of trace metals in soils within oil-bearing communities of Akwa Ibom State, Nigeria were examined. Top soils were obtained from Eket, Onna, Esit Eket, and Ibeno local government areas between January and December, 2017. Samples were also collected from Etinan local government area of the State and used as the Control. The samples and Control were subjected to standard analytical procedures and analysed for their physicochemical properties and total metal concentrations. The modified BCR methods were employed for the speciation of metals. The findings revealed that the pH levels were higher during the dry season while, the electrical conductivity, organic matter, and cation exchange capacity of the studied soils were higher in the rainy season. The total mean concentrations of Pb, As, Cd, Cr, Fe, and V were higher in the dry season whereas, Ni was higher in the wet season. Though, their concentrations were within the acceptable limits. Generally, the concentrations of all the parameters in the studied soils were higher than at the control site. Pb, As, Ni, and V existed predominantly in the reducible fraction, Cd and Cr in acid extractable while, Fe existed mostly in the residual fraction in the studied soils. However, at the control site all the metals except Cd existed mainly in the residual fraction. The study showed that all the studied locations were highly contaminated with these metals and substantial seasonal variations were also recorded for the pollution indices. It was also noted that, seasonal changes and oil activities were the key factors affecting the quality of the studied soils. Daily intake rates for the metals through exposure to soil for both the young and old populations were within their required oral reference doses. The non-carcinogenic risks recorded for both populations were less than one. However, both populations were exposed to high Pb and the younger ones were more susceptible. The study revealed the influence of seasonal change and oil activities on the mobility and toxicity of metals in the studied soils.
