Abstract

ÖZ: Bu çalışma, Erzurum civarındaki bazı
ağır element (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Sr, Pb) miktarlarını
ve Hydrophilidae (Coleoptera) türlerinin biyolojik izleme çalışmaları için
uygun aday olup olmadığını değerlendirmektedir. Bu amaçla, su, sediment ve
hydrophilid örnekleri Haziran, Temmuz, Ağustos 2014 aylarında Erzurum’daki dört
istasyondan toplandı. Aynı lokalitelerden alınan böcek, su ve sediment
örneklerindeki ağır element miktarları Enerji Dağılımlı X-Işınları Flüoresan
(EDXRF) spektrometresi ile ölçüldü. Sonuçlar böceklerin bulundukları ortamdan
kontamine olduklarını, bu nedenle, bazı elementleri yüksek miktarda biriktirdiğini
göstermiştir. Sediment ağır element analizleri, 14 element arasında en çok
biriken elementin  Cr olduğunu bunu Ni ve
Fe elementlerinin takip ettiğini gösterdi. Tüm istasyonlarda Ti, Fe, Ni, Cu,
Br, Pb konsantrasyonları su ve sedimentte ölçüldü; tüm böcek türleri Ti, Fe,
Ni, Cr, Zn, Br, Sr, Pb elementlerini farklı seviyelerde biriktirdi. Su
örnekleri ölçüm sonuçları ulusal su kalite parametreleri ile
karşılaştırıldı. Bazı elementlerin seviyesi, izin verilen limitlerin üzerinde bulundu.

Evaluation of Heavy Element Contamination Levels with the Use of Different Species of Hydrophilidae (Coleoptera) in Erzurum Province of Turkey

Abstract

ABSTRACT:
This study
evaluates the level of some heavy elements (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn,
As, Se, Br, Sr, Pb) in Erzurum Province, and to observe whether Hydrophilidae (Coleoptera) is a useful
candidate for biomonitoring studies. For this purpose, water, sediment
and hydrophilid samples were collected from four sites on June,
July, August 2014, Erzurum (Turkey). Heavy
elements levels in insect, sediment and water samples which are at the same
place were measured by Energy Dispersive X-Ray Fluorescence (EDXRF)
spectrometer. The results have showed that the hydrophilids were contaminated
by their environments, therefore
accumulated some elements at higher concentration. The sediments heavy
element analysis indicated that among the fourteen heavy elements Cr was
maximally accumulated, followed by Ni and Fe. In all sampling sites, Ti, Fe,
Ni, Cu, Br, Pb concentrations in water and sediment were measured, and every
insect species accumulated Ti, Fe, Ni, Cr, Zn, Br, Sr, Pb in different levels.
The water samples’ results were compared with national water quality criteria.
Some heavy elements’ concentrations exceed the allowable
limits.
