title: The investigation of heavy element accumulation in some Hydrophilidae (Coleoptera) species.
abstract: First of all, this study aimed to find out the measures of some heavy elements (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Sr, Pb) as heavy element pollution in Erzurum Province, and secondly to observe whether some hydrophilidae (Coleoptera) species can be used as a biomonitor. Insect samples were collected from five different localities of Erzurum in June, July, and August 2014. Heavy element levels in sediment, water, and insect samples were analyzed by energy-dispersive X-ray fluorescence (EDXRF) spectrometer device. According to the results of analysis derived through EDXRF spectrometry, heavy element concentrations display differences between stations and also species. The results pointed out that the insects were contaminated by the sediment and water; therefore, some hydrophilidae species accumulate higher concentration of elements than their environment. Results for levels in water were compared to national water quality guidelines. The values of some heavy elements found at higher concentration than acceptable limits.
