To evaluate the pollution level of toxic elements in edible mushrooms from Jilin Province, China, the lead, cadmium, mercury, and arsenic content present in them were monitored and evaluated. A total of 610 edible mushroom samples, including fresh and dried, were collected from nine cities in the Jilin Province. The concentrations of lead, cadmium, mercury, and arsenic ranged from 0.007 to 3.31, 0.006 to 48.52, 0.003 to 0.56, and 0.008 to 57.34 mg/kg, respectively, in dried samples, and 0.007 to 0.06, 0.006 to 0.17, 0.003 to 0.06, and 0.008 to 0.12 mg/kg, respectively, in fresh samples. The concentration of cadmium and arsenic exceeded the standard (Cd ≤ 0.2 mg/kg, Cd of Lentinus edodes ≤ 0.5 mg/kg, and As ≤ 0.5 mg/kg) in some mushroom samples. The bioconcentration levels of lead, cadmium, mercury, and arsenic depended on the edible mushroom species, environment, and the physicochemical properties of lead, cadmium, mercury, and arsenic. The results of the single factor pollution index, a method used to calculate the level of single elements in substances, showed that all edible mushrooms were at the level of unpolluted except Tricholoma matsutake and Pleurotus eryngii. The comprehensive factor (P) for T. matsutake was 1.093. The comprehensive factor pollution index, a method used to calculate the level of combined mixture in substances, was in the unpolluted level, except for T. matsutake. The pollution index results showed that cadmium and arsenic concentrations were lightly polluting in some mushroom samples. The health risk index for arsenic was the highest. Therefore, more attention should be paid to arsenic contamination in T. matsutake and P. eryngii in the Jilin Province, China. PRACTICAL APPLICATION: In this paper, we evaluated the contamination levels and associated safety issues of four toxic elements, lead, cadmium, mercury, and arsenic, in edible mushrooms. The results showed that cadmium and arsenic concentrations were lightly polluting in some mushroom samples.
为了评估中国吉林省食用蘑菇中有毒元素的污染水平，监测和评价了其中的铅、镉、汞和砷含量。从吉林省的九个城市共采集了 610 个新鲜和干燥的食用蘑菇样本。在干燥样本中，铅、镉、汞和砷的浓度范围分别为 0.007 至 3.31、0.006 至 48.52、0.003 至 0.56 和 0.008 至 57.34 毫克/千克，在新鲜样本中，铅、镉、汞和砷的浓度范围分别为 0.007 至 0.006、0.006 至 0.17、0.003 至 0.06 和 0.008 至 0.12 毫克/千克。在一些蘑菇样本中，镉和砷的浓度超过了标准（Cd≤0.2mg/kg，Cd 的香菇≤0.5mg/kg，As≤0.5mg/kg）。铅、镉、汞和砷的生物浓缩水平取决于食用蘑菇的种类、环境以及铅、镉、汞和砷的物理化学性质。单一元素污染指数（用于计算物质中单一元素水平的方法）的结果表明，除了松口蘑和杏鲍菇外，所有食用蘑菇均处于无污染水平。松口蘑的综合因素（P）为 1.093。用于计算物质中混合物综合水平的综合因素污染指数（P）除了松口蘑外，均处于无污染水平。污染指数结果表明，在一些蘑菇样本中，镉和砷的浓度为轻度污染。砷的健康风险指数最高。因此，在中国吉林省，应更加关注松口蘑和杏鲍菇中砷的污染问题。
在本文中，我们评估了中国吉林省食用蘑菇中四种有毒元素（铅、镉、汞和砷）的污染水平和相关的安全问题。结果表明，在一些蘑菇样本中，镉和砷的浓度为轻度污染。
