    An investigation on physical, chemical, and bacteriological quality of municipally supplied and well waters of the towns and city centre in the province of Nigde, Turkey
    (CARFAX PUBLISHING, 2004) Kara, E; Ozdilek, HG; Kara, EE
    Physical, chemical, and bacteriological properties of municipally supplied water and well water in selected towns and the city centre (Nigde, population 76,000) of the province of Nigde, located in central Anatolia, in Turkey, were investigated in this study. A composition of 70 samples were collected, 31 from Nigde city centre; 17 from Bor; 8 from Ulukisla; 6 from Altunhisar; 6 from Ciftlik and 2 from Camardi. Analyses showed that all the samples collected were found to have been chemically safe to consume for domestic purposes. Twenty-three water samples were found potentially unsafe because of the existence of coliform bacteria in them, which was probably caused by the inexistence of sufficient chlorination. Physical tests indicated that 11 water samples were found to have deposit; therefore, the use of such water causes risks where human health is a concern, based upon Turkish national standards (TSE, 1984).

    Evaluation of heavy metals' (Cd, Cu, Ni, Pb, and Zn) distribution in sowing regions of potato fields in the Province of Nigde, Turkey
    (KLUWER ACADEMIC PUBL, 2004) Kara, EE; Pirlak, U; Ozdilek, HG
    The Province of Nigde, located in central Anatolia, supplies approximately 25% of the total potato production in Turkey. In order to investigate selected heavy metals' (cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn)) presence in the region, soil samples from a total of 45 different sampling stations at two different locations (Misli and Altinhisar Plains) were evaluated for their total and extractable heavy metal contents along with their physical and selected chemical properties (pH, salt, CaCO3, phosphorus, soil organic matter, and soil texture) since bioaccumulation of the metals in potatoes might be a problem. Total lead and zinc concentrations were found to be almost at the same order of magnitude in both fields, whereas the total nickel concentration is significantly higher and the total cadmium and copper concentrations are lower in the Altinhisar Plain than the concentrations in the Misli Plain. The average total cadmium and copper concentrations in the Misli Plain, which are higher than the mean total cadmium and copper concentrations in the Altinhisar Plain, indicate that most probably heavy metal containing fertilizer and pesticide use over a long period of time in the Misli Plain has caused an increase in cadmium and copper accumulation in the soil.
