Determination of Arsenic (As) Concentrations in Drinking Water Sources of Antalya Province (Turkey)

Abstract

This study was carried out to determine the arsenic concentrations of water samples taken from Duraliler 1, Duraliler 2, Boğaçay, Yeniköy warehouse and Yeşilbayır depot stations which are used as drinking water source in Antalya between June 2013 and May 2014. Analyses were performed using EPA 200.8 method and ICP-MS instrument, and the results were evaluated monthly and seasonally. The results of the current study indicated that the highest arsenic level (13.01 µgL-1 ) was observed in Yeniköy water warehouse station in February whereas the lowest arsenic concentration (0.07 µgL-1 ) was determined in June at Boğaçay station. In the seasonal averages, the lowest As content between 0.08-0.97 µgL-1 was determined in Boğaçay station and the highest As content between 8.30-11.40 µgL-1 was determined in Yeniköy station. Seasonal average of the other stations were; Duraliler 1 station between 2.58 to 3.97 µgL-1 , Duraliler 2 station between 3.62 to 4.62 µgL-1 and Yeşilbayır water warehouse between 8.30 to 10.04 µgL-1 . The results of the study showed that Yeşilbayır and Yeniköy stations had higher content of As than the limit value <10 μgL -1 stated in Regulation Concerning Water Intended for Human Consumption. This could be fact that the pollution of As in the water sources is caused not only from the geological structure but also the use of As containing pesticides and herbicides in intensive farming which leaches into groundwater and reaches water sources. The areas containing high As content should be encouraged to transition to organic farming, and in case of the cumulative increase of As content, establishment of As treatment facility can also be considered. However, the first goal should be to take protection measures in the recharge basins of the sources.

Antalya İli İçme Suyu Kaynaklarında Arsenik Miktarının İncelenmesi

Öz

Bu çalışmada, Haziran 2013 - Mayıs 2014 tarihleri arasında Antalya ili içme suyu kaynağı olarak kullanılan Duraliler 1, Duraliler 2, Boğaçay, Yeniköy depo ve Yeşilbayır depo istasyonlarından aylık olarak alınan su numunelerinin arsenik (As) miktarları 1 yıl süreyle incelenmiştir. Analizler ICP-MS cihazında EPA 200.8 metodu kullanılarak yapılmış ve elde edilen sonuçlar aylık ve mevsimlik olarak değerlendirilmiştir. Çalışma süresince en yüksek arsenik miktarı Şubat ayında 13,01 µg/L ile Yeniköy depo istasyonunda, en düşük arsenik miktarı ise Haziran ayında 0,07 µg/L ile Boğaçay istasyonunda ölçülmüştür. Su depolarındaki mevsimlik ortalama en düşük arsenik içeriği 0,08-0,97 µg/L ile Boğaçay istasyonunda, en yüksek arsenik içeriği ise 8,30-10,67 µg/L ile Yeniköy depo istasyonunda tespit edilmiştir. Diğer istasyonlardaki mevsimlik ortalama arsenik içerikleri ise; Duraliler 1 istasyonu 2,58-3,97 µg/L, Duraliler 2 istasyonu; 3,62-4,62 µg/L ve Yeşilbayır depo istasyonu; 8,30-10,04 µg/L aralığında belirlenmiştir.

Çalışma sonucunda Yeşilbayır ve Yeniköy depolarında elde edilen bazı verilerin İnsani Tüketim Amaçlı Sular Hakkındaki Yönetmelikte belirtilen 10 μg/Llimit değerinin üzerinde olduğu tespit edilmiştir.
