Drinking Water Samples

The objective of this study was to analyze drinking water samples from 21 sites in the city center and seven municipalities of Tunceli, Turkey, in order to determine the presence of nitrate, nitrite, fluoride, bromate, pesticides, polycyclic aromatic hydrocarbons (PAHs), trihalomethanes (THMs), and some other chemicals. In all locations, the concentrations of chemicals investigated were below the permissible limits set by local and international organizations for drinking water. Low levels of nitrate (4.79 ± 4.20 mg/L), fluoride (0.11 ± 0.08 mg/L), and THMs (6.63 ± 5.14 μg/L) were detected in all locations. A low level of tetra, chloroethane, which is suspected to be a human carcinogen, was also detected in 8 locations in the range of 0.26–0.43 μg/L. These contaminants may pose adverse health effects or minimum hazard due to long-term exposure. In all locations, bromate, benzene, total PAH, 1-2 dichloroethane, vinyl chloride, acrylamide, and epichloridine levels in drinking water samples were under detection limits.

Drinking Water Samples

The drinking water quality is associated with the conditions of the water supply networks, the pollution and the contamination of groundwater with pollutants of both anthropogenic and natural origin. In this study, water samples were taken from four different waterworks in Tunceli, Turkey and heavy metals concentrations (As, Cu, Cd, Cr, Pb, Ni and Hg) were measured. Four sampling sites were pre-defined in different locations of the city. The obtained results showed that, the heavy metals concentrations in water samples did not exceed the values of WHO (World Health Organization), EC (Europe Community), EPA (Environment Protection Agency) and TSE-266 (Turkish Standard) guidelines.

The method for concentration of Cryptosporidium oocysts in large drinking water samples using the Envirocheck capsule has been optimized for the detection of low levels of oocysts. Elution from the filter by contact time and vortex agitation gave 68% oocyst recovery. Centrifugation (1,250 g; 30 min; 4°C) improved recovery to 94% without morphological damage of the oocysts. Increasing the ratio of magnetic beads to sample volume in the IMS procedure led to 69% efficiency. In these conditions, the overall recovery of the procedure was 49% as assessed with low oocysts spike doses in 100 litres tap water samples. The methodology described allows the detection of 0.1 oocyst per litre when 100 litres samples are processed.

Abstract A rapid and efficient method based on solid phase extraction and liquid chromatography–tandem mass spectrometry was validated, allowing the determination of the endocrine-disrupting herbicides (acetochlor, alachlor, amitrole and atrazine), fungicides (carbendazim, triadimefon, penconazole and propiconazole), and insecticides (carbaryl and carbofuran) in drinking water. Low method detection limits (0.01–0.64 ng/L) and method quantification limits (0.03–2.13 ng/L) were obtained with satisfactory recoveries and precision for the endocrine-disrupting pesticides. The method was applied for real drinking water samples collected in the area of the city of Hangzhou (Zhejiang, China); the results showed that carbendazim, atrazine and acetochlor were detected in the drinking water samples and acetochlor was the most detected analyte.

The occurrence of trihalomethanes (THMs) was studied in the drinking water samples from urban water supply network of Karachi city that served more than 18 million people. Drinking water samples were collected from 58 locations in summer (May-August) and winter (November-February) seasons. The major constituent of THMs detected was chloroform in winter (92.34%) and summer (93.07%), while the other THMs determined at lower concentrations. Summer and winter concentrations of total THMs at places exceed the levels regulated by UEPA (80 μg l-1) and WHO (100 μg l-1). GIS linked temporal variability in two seasons showed significantly higher median concentration (2.5%-23.06%) of THMs compared to winter.
