Abstract

Water quality has a major importance for public health. However, nitrite and nitrate levels in water are still an important contamination issue in the world. The aim of this study was to determine the levels of total nitrite and nitrate in public water (tap water) and wells from different districts of Istanbul city and to evaluate the seasonal variation from November 2013 to March 2014. The average levels in tap waters were highest in March 2014 compared with November, December 2013 and February 2014. Two of the tap water and 3 of the well water samples exceed the maximum acceptable concentration according to the U.S. Environmental Protection Agency (10 ppm). However, these levels were still lower than the maximum allowable limits reported in official documents of Turkey. Also, in order to determine the annual variation, tap water samples were collected between December 2012 and February 2013 and evaluated for total nitrite and nitrate levels. Results showed that total nitrite and nitrate levels during December 2013 and February 2014 were decreased in the ratio of 2, 10 and 18% compared to the same months during December 2012 and February 2013. In conclusion, our results suggested that due to seasonal and annual variations, nitrite and nitrate levels of waters should be routinely controlled to prevent various health hazards.

Özet

Suyun kalitesi halk sağlığı için çok önemlidir. Ancak sularda nitrit ve nitrat düzeyleri hala önemli bir kontaminasyon problemidir. Bu çalışmanın amacı İstanbul'un farklı bölgelerinden toplanan musluk suyu ve çeşme sularında toplam nitrit ve nitrat düzeylerini tespit etmektir. Bu amaçla çeşitli bölgelerden musluk suyu örnekleri Kasım 2013'den Mart 2014'e kadar toplanmış ve değerlendirilmiştir. Su örneklerinde ortalama toplam nitrit ve nitrat düzeyleri Kasım, Aralık 2013 ve Şubat 2014 ile karşılaştırıldığında Mart 2014'te en yüksektir. ABD Çevre Koruma Ajansına göre, musluk sularından iki tanesi ve kuyu sularından üç tanesi toplam nitrat ve nitrit için maksimum kabul edilebilir konsantrasyonu (10 ppm) aşmaktadır. Ancak tüm örneklerde bu düzeyler Türkiye'nin resmi dökümanlarında bildirilen maksimum kabul edilebilir düzeylerin altındadır. Ayrıca, yıllar arası değişimi saptamak için, bir önceki yıla ait su örnekleri de değerlendirilmiştir. Sonuçlar Aralık 2013-Şubat 2014 döneminde toplam nitrit ve nitrat düzeylerinin Aralık 2012-Şubat 2013 dönemine göre %2, 10 ve 18 oranında azalma göstermiştir. Sonuçlarımıza göre, mevsimsel değişim göz önüne alınarak, halk sağlığının korunması için sularda nitrit/nitrat düzeyleri rutin olarak kontrol edilmelidir.
