Arsenic (As) contamination is endemic in West Bengal, India. Arsenic exposure through mushroom is lethal to health. Pleurotus sp. is globally consumed as food for its medicinal and nutritional values. This study was performed to evaluate the arsenic accumulation in mushroom through arsenic biomagnified rice straw substrate in relation to health risk assessment. Arsenic concentrations were higher in P. ostreatus (12.577 mg/kg DW) and Pleurotus sp. (12.446 mg/kg DW) cultivated in arsenic biomagnified rice straw as compared with P. ostreatus (0.472 mg/kg DW) and Pleurotus sp. (0.434 mg/kg DW) cultivated in non-contaminant rice straw; respectively. The bio-concentration factor (BCF) value of arsenic was highest in stem at 3rd flush for both P. ostreatus and Pleurotus sp. The health risk index (HRI) based on dietary intake of these arsenic biomagnified mushrooms was found moderately higher in both the species, so higher intake of these mushrooms will put people at health risk.

参考健康风险评估的砷及其对牡蛎蘑菇营养特性的影响。

砷 (As) 污染在印度西孟加拉邦流行。通过蘑菇接触砷对健康是致命的。平菇 因其药用和营养价值而被全球消费。本研究旨在通过砷生物放大稻草基质评估蘑菇中砷的积累与健康风险评估的相关性。P. ostreatus (12.577 mg/kg DW) 和 Pleurotus sp. 中的砷浓度较高。(12.446 mg/kg DW) 与 P. ostreatus (0.472 mg/kg DW) 和 Pleurotus sp. 相比，在砷生物放大稻草中栽培。(0.434 mg/kg DW) 在非污染稻草中栽培；分别。P. ostreatus 和 Pleurotus sp. 的茎中砷的生物浓度因子 (BCF) 值在第 3 次冲洗时最高。
