In this study, conducted on 100 samples of potable water and tap water taken from 10 different water stations selected randomly from various locations within Van City center, levels of heavy metals lead, manganese, cadmium, zinc, copper, iron, nickel, cobalt and certain macro elements magnesium, sodium, calcium were determined with Atomic Absorption Spectrophotometer AAS . Heavy metal concentrations of water samples were found to be as follows: Pb 0.016-0.082 mg/L, Mn 0.007-0.015 mg/L, Cd 0.001-0.005 mg/L, Zn 0.03- 0.40 mg/L, Cu 0.006- 0.11 mg/L, Fe 0.001-0.18 mg/L, Ni 0.012-0.046 mg/L, Co 0.007-0.014 mg/L; and macro element concentrations were as follows: Mg 6.78-6.81 mg/L, Na 3.88-6.68 mg/L and Ca 31.06-38.49 mg/L. According to the above data, lead levels in all water samples are found to be over national and international standards.
V an şehir merkezinde bulunan değişik yerlerden rastgele seçilen 10 farklı istasyondan alınan 100 içme ve musluk suyu numunesi üzerinde yapılan bu çalışmada ağır metal kurşun, mangan, kadmiyum, çinko, bakır, demir, nikel, kobalt ve bazı makro element magnezyum, sodyum, kalsiyum seviyeleri Atomik Absorbsiyon Spektrometresiyle AAS belirlendi. Su numunelerinin ağır metal seviyeleri şöyle bulundu: Pb 0.016-0.082 mg/L, Mn 0.007-0.015 mg/L, Cd 0.001-0.005 mg/L, Zn 0.03-0.40 mg/L, Cu 0.006- 0.11 mg/L, Fe 0.001-0.18 mg/L, Ni 0.012-0.046 mg/L, Co 0.007-0.014 mg/L; makro element seviyeleri ise şöyleydi: Mg 6.78-6.81 mg/L, Na 3.88-6.68 mg/L ve Ca 31.06-38.49 mg/L. Bu verilere göre tüm su numunelerindeki kurşun seviyesi ulusal ve ulusılar arası standartların üstünde bulunmaktadır
