Yenilebilir Böcek Türü Cybister limbatus (Fabricius 1775) ve Ağır Element Seviyeleri Üzerine Bir Ön Çalışma

Bu çalışmanın amacı yenilebilir böcek paketlerindeki ağır element miktarını değerlendirmek ve bu böcek paketinin tüketimi yoluyla insanlar için sağlık riskini değerlendirmektir. Çalışma için sucul yenilebilir böcek Cybister limbatus (Fabricius 1775) (Coleoptera: Dytiscidae) seçilmiştir. Bu türde on altı ağır element (Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Pb) tespit edilmiştir. Çalışma için EDXRF (Enerji Dağılımlı X-Işını Floresans) spektrometresi kullanılmıştır. Çalışılan 16 element arasında Ca (0,98 ppm), Ti (0,49 ppm) ve V (0,38 ppm) en yüksek konsantrasyonda, Rb (0,05 ppm), Sr (0,04 ppm), As (0,32 ppm), Br (0,06 ppm) ve Pb (0,06 ppm) ise en düşük konsantrasyondadır. Sonuçlar Birleşmiş Millletler İlaç Enstitüsü mikrobesin esasları hakkındaki panel ile karşılaştırıldığında, bu çalışmadaki değerler tüketim için uygun görülmüştür. Fakat, özellikle potansiyel zararlı elementlerden olduğu düşünülen Pb ve As miktarı gelecekte sağlık problemleri oluşturabilir.

Preliminary Study on Edible Insect Species Cybister limbatus (Fabricius 1775) and Its Heavy Element Contents

The objective of the study was to determine the concentration of heavy elements in edible insect pack andestimate the potential health risks of elements to humans via consumption of the insect pack. Aquatic edible insect Diving Beetlepack, Cybister limbatus (Fabricius 1775) (Coleoptera: Dytiscidae) was chosen for the study. Sixteen heavy elements (Ca, Ti, V,Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Pb) were determined in the edible beetle. Energy Dispersive X-ray Fluorescence(EDXRF) was used to determine the concentration of the elements. Among the sixteen studied elements Ca (0.98 ppm), Ti (0.49ppm) and V (0.38 ppm) had the highest concentration, whereas Rb (0.05 ppm), Sr (0.04 ppm), As (0.32 ppm), Br (0.06 ppm) andPb (0.06 ppm) had the lowest concentration. The results compared with US institute of medicine (IOM) panel on micronutrientguidelines, the levels of elements in this study were found safe for consumption. But especially residues of Pb and As, which arethought as the potential hazardous elements, in this edible insect may pose health problem in the future.
