Abstract This study was conducted to calculate the burden of heavy metals i.e., aluminium (Al), arsenic (As), barium (Ba) and lead (Pb) in the river water of Punjnad Headworks, Bahawalpur, Pakistan. For this purpose, samples were collected from surface water, bed sediments and planktons during autumn, winter and spring seasons (September 2018 to May 2019). The results showed that in surface water Pb concentration was highest (453.87 mg L-1), while in sediments and plankton, Al concentration was highest (370.24 µg g-1 and 315.05 µg g-1, respectively). A significant difference (p < 0.000) in metal concentrations was found among surface water, bed sediments and plankton at different sampling stations during various seasons. However, findings of this study showed no adverse effects of heavy metal concentrations on human health. This study provided better understanding of various pollutants and their concentrations in water sources at the studied location.

In this study, through the analyses of water samples taken from 9 stations on the brook between July 2012 and June 2013, we aimed to determine the monthly and seasonal changes in water quality parameters of Brook Kuruçay, to determine the water quality properties, to reveal the pollution problems, to determine the suitability level in terms of aquatic life and to classify the quality of water in accordance with Surface Water Quality Management Regulation’s Inland Surface Water Classes criteria. The study area is located southeast of the Hafik District of Sivas city and the altitude is 2608 m. The water samples were collected from 9 stations established on the brook, and some physicochemical parameters and heavy metal concentrations were analyzed in water samples. The cleaning and maintenance of all of the equipment, land-type measurement tools, and glass sampling containers to be used in sampling were made 1 day before sampling. Sampling tubes were immersed into 15 cm below the water surface for taking water samples. Heavy metal concentrations were determined in the Sivas Provincial Control Laboratory in the same day with sampling (within 5 hours). The total alkalinity, total hardness, ammonium nitrogen, nitrite, nitrate, ammonium azote, phosphate, sulfite, sulfate, chloride, sodium, potassium, suspended solid matter (SSM), chemical oxygen demand (COD), biological oxygen demand (BOD), calcium, magnesium, ferrous, lead, copper, zinc, nickel, mercury and cadmium analyses of water samples were performed. As a result of the analyses, it was determined that, since Brook Kuruçay falls into the water resource class, which is the most sensitive to pollution, the water quality of the brook should be monitored regularly.

Heavy Metal Concentrations

Assessing heavy metal concentrations in wetlands and identifying sources of metal contamination are critical steps in protecting wetlands. Using seven sampling stations, we evaluated the spatial variation of some heavy metal concentrations in surface waters of the Mohammedia wetland and a selected segment of the El Maleh wadi that feeds the wetland. Field observations made it possible to identify and map the pollution discharged into El Maleh wadi, carrying heavy metals into the wetland. The analyses showed that the concentrations of lead, manganese, and cadmium far exceed the thresholds relating to fish life in 100% of sampling stations. All the evidence points to heavy metals contamination of surface water in Mohammedia wetland, generated by industrial activities, wastewater discharges, and leachate from the old landfill located upstream.

Agrochemicals, geochemical structure and industrial wastes create a potential source of heavy metal pollution in the aquatic environment. The porpuse of this study was to investigate the seasonal variations in five heavy metals (Cu, Zn, Cd, Pb and Cr) in the surface water of the Keritis river, one of the most important rivers in Chania, Greece. The surface water samples were colloected at 8 sampling sites in the Keritis river system. Seven sampling campaigns were carried out in each site in a 1-year period, during August 2004 to July 2005. Heavy metals were determined by using flame and furnace Atomic Absorption Spectrometry. Ancillary data included water temperature, pH and electric conductivity. Significant variations were observed between the warm period (May to September) and the wet period (October to April), for the studied metals. Heavy metal concentrations were sufficiently higher in warm period than in wet period. The average concentrations in wet and warm period were: Cu (0.88 μg l-1; 6.62 μg l-1), Cd (0.005 μg l-1; 0.019 μg l-1), Pb (0.28 μg l-1; 2.59 μg l-1), Cr (1.44 μg l-1; 3.25 μg l-1), and Zn (4 μg l-1; 39 μg l-1), respectively. The relative variability followed the order: Zn>Pb>Cu>Cd>Cr. The seasonal variations may be due to either anthropogenic causes, such as agricultural practices, especially the use of fertilizers and biocides or wastewater discharge, or natural causes, such as water temperature, pH, redox condition, or river flow. The water pH was lower in warm period than in wet period. The concentrations of Cu, Zn, Cd, Pb and Cr were found to be positively related to the water pH in both periods. The water temperature was higher in the warm period and no strong, but remarkable correlations were found between the heavy metal concentrations and the temperature values for the warm and the wet period. Also, there was found no correlation between the heavy metal concentrations and the electrical conductivity.
