Hygiene. Preventive Medicine Food and food supply in relation to public health Mushrooms Introduction: Mushroom able to take up pollutants in their fruiting bodies during growth stage and this include the accumulation of heavy metals in mushroom tissue which unevenly distributed between head and stipe parts. Objective: Three metal elements (Cadmium, Lead and Copper) were studied to evaluate the contamination of heavy metals in grey oyster (Pleurotus sajor-caju) mushroom and to assess the potential health risk towards consumer. Methodology: Twenty mushroom samples including head and stipe and twenty substrate samples were collected from farms in Selangor. The concentration of Cd, Pb and Cu in samples was determined by using Atomic Absorption Spectrometer (AAS) after acid digestion process. Finding: Cu had the highest accumulation in head and stipe of the mushroom at 13.18 mg/kg and 10.52 mg/kg, respectively while the lowest reading for both parts was Cd with 1.08 mg/kg and 0.59 mg/kg. There was significant difference between concentration of Cd, Pb and Cu in head and stipe of the mushroom. Concentrations of the three metals in substrate were statistically correlated with concentration in head and stipe. Bioconcentration factor (BCF) was calculated and most of head and stipe were bioexclusors to Cd, Pb and Cu. Target Hazard Quotient (THQ) of Cd, Pb and Cu was less than one but hazard index (HI) showed that both head and stipe were above one and indicated that consumption of P. sajor-caju mushroom may cause adverse health effect. Conclusion: Substrate composition played a role in the bioaccumulation in P. sajor-caju as increasing of heavy metals concentration in substrate bring significant impact on the concentration in mushroom. Proper cooking and processing mushroom to leach out heavy metals were recommended in ensuring quality of food and lowering the health risk 2018 Thesis https://ir.uitm.edu.my/id/eprint/42213/ https://ir.uitm.edu.my/id/eprint/42213/1/42213.pdf text en public degree Universiti Teknologi MARA ( Kampus Puncak Alam ) Faculty of Health Sciences Mohd Shahid, Nadiatul Syima
