Bioaccumulation of Cadmium in Edible Wild Mushroom (Suillus Luteus), Bulgaria
Bioaccumulation of Cadmium in Edible Wild Mushroom (Suillus Luteus), Bulgaria

Summary/Abstract: The study was conducted on Cambisols soils and wild edible mushroom (Suillus Luteus) from the Batak Mountain, Bulgaria. The total cadmium content in the soils was measured after their decomposition with HCl and HNO3 acids. The mushroom samples were prepared by dry ashing and subsequent dissolution in HCl. The cadmium levels were determined by PerkinElmer AAnalyst 800 model atomic absorption spectrometer (PerkinElmer Instruments, Shelton, CT, USA) equipped with transversely heated graphite atomization (THGA), and a longitudinal Zeeman effect background corrector was also used. A correlation/regression analysis was carried out to reveal possible associations between pH, humus content, and total cadmium content of the soils and the concentration of this element in the mushroom samples. It was calculated BF = 0.38. BF < 1 indicates that the fungus is a metal ion bioreactor.
