abstract = "Humans are exposed to the chemicals from very different sources. Therefore, the
exposure assessment should be focused on mixtures rather than single chemicals. In this
study, bioelements (Zn and Cu) homeostasis effects of mixture of Cd and BDE-209, widely
spread persistent environmental pollutants, has been evaluated. In order to evaluate the
potential of mixture on Zn and Cu homeosthasis in rats kidneys, Wistar rats were treated by
oral gavage during 28 days with three doses of Cd 2.5, 7.5, and 15 mg/bw/day, three
combinations of Cd with 1000 mg BDE-209/kg/day, and water as a control group. Kidney
tissue samples were collected, mineralised, and Cu and Zn levels were measured by flame
atomic absorbtion spectrophotometer. Possible interactions were evaluated comparing the
dose-response curves slopes and lower confidence limit of Benchmark dose of 10%
(BMDL10) were calculated by PROAST software (RIVM, Netherlands). Cd alone can disturb
Zn in kidneys and calculated BMDL10 was 1.713 mg Cd/kg/day, while in combination with
BDE-209 it was 1.719 mg/kg/day. Cd disturbs Cu in kidney in significantly higher dose of
5.679 mg Cd/kg/day. However, in combination with the BDE-209, derived BMDL10 was 10
times lower, 0.517 mg Cd/kg/day. Dose-response curve slope for the effect on Cu was
significantly lower in the case of mixture effect than in the case of Cd effect. Since Cu plays a
major role in the blood cells creation and health of other systems, our results indicate more
potent activity of the mixture than single Cd., Ljudi mogu biti izloženi hemikalijama iz različitih izvora, te je potrebno procenjivati
efekte na bazi izloženosti smešama hemikalija, pre nego pojedinačnim hemikalijama. U
studiji je analiziran uticaj smeše Cd i BDE-209, široko rasprostranjenih zagađujućih
perzistentnih supstanci, na homeostazu bioelemenata, cinka (Zn) i bakra (Cu). U cilju
evaluacije potencijala smeše da naruši homeostazu Zn i Cu u bubrezima pacova, Wistar
pacovi su oralnom gavažom bili tretirani tokom 28 dana dozama Cd od 2,5, 7,5 i 15
mg/kg/dan, kombinacijama ove tri doze sa 1000 mg BDE-209/kg/dan i vodom kao
kontrolom. Tkivo bubrega je izdvojeno, zatim mineralizovano, a sadržaj Zn i Cu je meren
atomskom apsorpcionom spektrofotometrijom. Moguće interakcije su procenjivane
poređenjem nagiba krivih doza-odgovor, a izračunate su i donje granice pouzdanosti
Benchmark doze od 10% (BMDL10) korišćenjem PROAST softvera (RIVM, Holandija). Cd
primenjen sam utiče na homeostazu Zn u bubregu i izračunata BMDL10 iznosi 1,713
mg/kg/dan, dok u kombinacji sa BDE-209 iznosi 1,719 mg/kg/dan. Cd ometa homeostazu Cu
u bubregu pacova i BMDL10 iznosi 5,679 mg/kg/dan, dok je u kombinaciji sa BDE-209 BMDL
10 puta niža i iznosi 0,517 mg/kg/dan. Nagib krive doza odgovor za smešu Cd i BDE-209 bio
je daleko niži od nagiba krive doza-odgovor za Cd. S obzirom na to da Cu igra značajnu ulogu
u nastanku krvnih ćelija, ali i u očuvanju durgih sistema organa, dobijeni rezultati iziskuju
pažnju zbog daleko potentnijeg uticaja smeše na nivo Cu u odnosu na uticaj samog Cd.",
