Van Merkez ve Çevresindeki Sularda Bazı Ağır Metal Düzeylerinin Araştırılması

Bu çalışmada, Van iline ait 52 istasyondan alınan içme, sulama, kuyu içme sulan ile çimento fabrikası atık suyu ve yol kenan birikinti sulannda Cu, Zn, Fe, CdvePb elementleri Atomik Absorpsiyon Spektrofotometre ile tayin edildi. Anallz sonucunda içme sulannın metal konsantrasyonlan Fe 0.01-3 mg/l , Zn 0.005-0.220 mg/l , Pb 0.005-0.024 mg/l , Cu 0.005-0.035 mg/l ; sulama sulannın metal konsantrasyonlan Fe 0.03-2.71 mg/l , Pb 0.005-0.050 mg/l , Cu 0.005- 0.012 mg/l ; Zn 0.005-0.013 mg/l ; kuyu içme sulannın metal konsantrasyonlan aralıklan, Fe 0.03-1.30 mg/l ; Zn 0.006-0.257 mg/l ; Pb 0.0050.017 mg/l ; Cu 0.005-0.013 mg/l , birikinti ve atık sularda metal konsantrasyonlan, Fe 0.35-2.40 mg/l , Pb 0.007-0.124 mg/l , Zn 0.006-0.034 mg/l , Cu 0.008-0.030 mg/l arasında bulunmuştur. Cd miktan Atomik Absorpsiyon Spektrofotometrenin tayin sınırının altında kaldı. Bu nedenle Cd değeri sadece üç istasyon için tayin edilebildi. İçme ve kuyu içme sulama sulan, bazı standartlann belirlediği limit değerler ile karşılaştırıldı. Birikinti ve atık sulan, çimento fabrikası atık suyu ve çimento fırın bacasından yayılan toz partikülleri ile Fe, Cd, Zn ve Cu yönünden çevreyi kirlettiği belirlendi. Yol kenanndaki birikinti sulannda ise Pb miktan yüksek olarak bulundu

An Investigation of Some Metal Levels in Van and It’s Surroundings in IVaters

This study was carried out to determine the Cu, Zn, Fe, Cd and Pb in drinking, irrigation, yvell drinking, accumulate yvater and in yvasteyvater of cement factory. The yvater samples vvere taken from 52 statioııs in Van and it's surrounding. The elements yvere determined by Atomic Absorption Spectrophotometer. At the result of analysis, the ranges of metal concentrations in drinking fresh yvater are as folloyvs: Fe 0.01-3 mg/l , Zn 0.005-0.220 mg/l , Pb 0.005-0.024 mg/l , Cu 0.005-0.035 mg/l . The range values of metal concentrations in irrigation yvaters are as folloyvs: Fe 0.03-2.71 mg/l , Pb 0.005-0.050 mg/l , Cu 0.005-0.012 mg/l , Zn 0.005-0.013 mg/l . The range values of metal concentration in yvell drinking fresh yvaters are as folloyvs: Fe 0.03-1.30 mg/l ; Zn 0.006-0.257 mg/l ; Pb 0.005-0.017 mg/l ; Cu 0.005-0.013 mg/l . İn accumulate yvater and yvaste yvaters the range values of the metals are as folloyvs: Fe 0.35-2.40 mg/l , Pb 0.007-0.124 mg/l , Zn 0.006-0.034 mg/l , Cu 0.008-0.030 mg/l . The Cd value yvas under determination limit value of the atomic absorption spectrophotometer. For this reason the Cd values yvere determined only for three stations. The results of analysis for drinking fresh yvaters, yvell-yvater, irrigate yvaters compared to each other some standards. İn accumulate and yvaste yvater of cement factory dust emitted from chimneys of cement kiln has made pollution in environment by metals of Fe, Cd, Zn, Cu. Hoyvever, in accumulate yvaters near the roads the Pb values determined high
