Oxidative stress and heavy metal levels of pholiota limonella mushroom collected from different regions
Özet
Background: The objective of the present study is to determine and compare TAS (Total Antioxidant Status), TOS (Total Oxidant Status) and OSI (Oxidative Stress Index) and heavy metal content (Fe, Zn, Cu, Pb and Ni) in Pholiota limonella (Peck) Sacc. mushroom samples collected from Balıkesir (Kaz Mountain National Park) and Yalova (Çınarcık, Hasan Baba Picnic Area) provinces. Methods: Mushroom TAS, TOS and OSI values were determined using Rel Assay Diagnostics kits. Heavy metal content was determined using an atomic absorption spectrophotometer. Results: As a result of the studies, TAS values in the samples collected from Balıkesir and Yalova were; 2.378 and 2.263 mmol, respectively; TOS values were, 4.742 and 33.022 ?mol; while OSI valueswere determined to be 0.199 and 1.459,respectively. Fe, Zn, Cu, Pb and Ni contents were found to be 31.41, 7.13, 2.45, 3.97 and 0.49, respectively, from Balikesir and 361.50, 46.64, 11.93, 10.58 and 1.02, respectively, from Yalova. Conclusion: Study findings demonstrated that the samples collected at Yalova province had higher heavy metal content and OSI value. As a result, the samples collected from Balıkesir (Kaz Mountain National Park) were concluded to be healthier. © 2018 Bentham Science Publishers.
