Abstract

Introduction. Existing
literature indicate that elements are present in varying
concentration in all ecosystems but anthropogenic activities increase the level
of this pollutants. Aim of the study. To find out concentration of some heavy elements (Ti,
V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Sr, Pb) as heavy element pollution
in Erzurum (Turkey), accumulation
level of Hydrophilidae (Coleoptera) and Chondrostoma regium species and to assess the health status of Erzurum
wetlands. Material and methods.
Water, sediment, fish and insect samples were collected
in Karasu River (Erzurum, Turkey). Heavy elements levels in insects and
abiotic samples were analyzed by Energy Dispersive X-Ray Fluorescence (EDXRF)
spectrometer. Fish tissues, from the same
habitat were measured by ICP-MS. Results. The
elements concentrations were found to increase from fish tissues to insects
(fish tissues< sediment < water <insects). It can be said that insects accumulate more heavy elements than fish
tissues thus insects can be one of the source of contamination of the fish. All results were well
below the limits for fish proposed by national
and international standards and did not pose a health concern for fish
consumers. Conclusions. Based on
the analyses of fish samples, heavy element concentrations in fish from studied
areas of Erzurum are low. Although levels of heavy element are not high,
residue of Pb, Cd and Hg in food may cause health problem for future.

Keywords: Aquatic insects, fish, EDXRF, ICP-MS, health hazard.
