Concentrations of trace elements aluminum, boron, cobalt and tin in various wild edible mushroom species from Buyuk Menderes River Basin of Turkey by ICP-OES

摘要

Objective: The investigation of the scale of environmental pollution is a major step towards preventing environmental pollution. Biomonitoring within an ecological programme involves the systematic use of living beings for obtaining quantitative information on changes in the environment, often due to anthropogenic activities. Material and methods: Trace metal levels in thirty-four different wild-growing edible mushroom species from Buyuk Menderes River Basin, West Anatolia, Turkey were determined by inductively coupled plasma optical emission spectroscopy (ICP-OES; Perkin Elmer, Optima 7000 DV). Results: The contents of trace elements in the mushroom samples were found in the ranges, 53.96 - 3308,0.229 - 46.93,0.005 - 2.224 and 2.809 - 4.711 mg/kg for aluminum, boron, cobalt and tin, respectively. Al content was the highest in Pleurotus ostrea-tus (3308 mg/kg), and the lowest in Laetipo-rus sulphureus (53.96 mg/kg). B content was the highest in Coprinus micaceus (46.93 mg/ kg), the lowest in Oudemansiella radicata (0.229 mg/kg). It was determined that Co content was the highest in Clavulina cristata (2.224 mg/kg), whereas the lowest in Agari-cus bitorquis (0.005 mg/kg). In terms of Sn content, Agaricus campestris (4.711 mg/kg) was the highest, and Suillus bellinii (2.809 mg/kg) was the lowest. Conclusion: Results could be explained by the fact that there are no industrial activites that emit these metals.
