ÖZ :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

ABSTRACT:
The objective of the study was
to determine the concentration of heavy elements in edible insect pack and
estimate the potential health risks of elements to humans via consumption of
the insect pack. Aquatic edible insect Diving Beetle pack, 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 (0.49 ppm)
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) and Pb (0.06 ppm) had the lowest concentration. The results
compared with US institute of medicine (IOM) panel on micronutrient guidelines,
the levels of elements in this study were found safe for consumption. But
especially residues of Pb and As, which are thought as the potential hazardous
elements, in this edible insect may pose health problem in the future.
