Kentsel arıtma sularında bazı toksik metal seviyelerinin değerlendirilmesi

Abstract

Kullanılan suyun kalitesi ve sucul çevre, tüm organizmaların sağlığını ve yaşamını kontrol eden önemli faktörlerdir. Endüstrinin gelişmesiyle doğal kaynakların aşırı kullanımı, çevre kirliliğinin hızla artmasına sebep olmakta ve suda yaşayan organizmaların en önemli tehdit edici faktörleri olarak kabul edilen organik ve inorganik maddeler çevreye yayılmaktadır. Metaller sulardaki en önemli inorganik kirlilik kaynağıdır. Bu çalışmada Karaman ili ve çevresindeki bazı yerleşim yerlerindeki arıtma sularında bazı toksik metallerin seviyeleri belirlenmiştir. Bu amaçla arsenik, kobalt, bakır, çinko, kadmiyum, krom ve kurşun metallerinin miktarları İndüktif Eşleşmiş Plazma Optik Emisyon Spektrometresi (ICP-OES) yöntemiyle analiz edilmiştir. Dünya Sağlık Örgütü ve Türk Standardı Enstitüsü-266'ya (TS-266) göre, analiz edilen su örneklerinde arsenik, kadmiyum, çinko, krom, kobalt ve kurşun açısından kirlenme olmadığı ancak bakır elementi için Türk Standardı Enstitüsü-266'ya göre izin verilen sınır değerlerin üstünde olduğu tespit edilmiştir.

Evaluation of some toxic metal levels in urban treatment waters

Abstract

The quality of the water used and the aquatic environment are important factors that control the health and life of all organisms. Industrial development, excessive use of natural resources cause environmental pollution to increase rapidly and organic and inorganic substances, which are considered as the most important threatening factors of aquatic organisms, are spreading to the environment. Metals constitute the most important source of inorganic pollution in waters. In this study, the levels of some toxic metals in Karaman province and its surrounding settlements treatment waters were determined. For this purpose, the amounts of arsenic, cobalt, copper, zinc, cadmium, chrome and lead metals were analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) method. According to Word Health Organization and Turkish Standard Institute-266 (TS-266), it was found that there was no pollution in terms of arsenic, cadmium, zinc, chrome, cobalt and lead in the water samples analyzed, but it was above the permissible limit values according to Turkish Standard Institute-266 for copper element.
