摘要

在这项研究中，48种不同的野生和栽培蘑菇是从马德里当地市场购买的，并由马德里真菌学学会值得信赖的专家提供。采用电感耦合等离子体质谱法(ICP-MS)测定了在微波炉中消化的样品中的镉、汞和铅。采用微波辅助萃取后的液相色谱分离- ICP-MS法测定甲基汞(MeHg)。在镉和铅含量方面，所有样本均符合最高容许限量。就汞而言，单个样品的汞含量超过了法规(EU) 2018/73规定的野生蘑菇最大值。就甲基汞而言，最高含量占一个样品中汞总量的13%。在其他情况下，发现的浓度可以忽略不计。

Study of Heavy Metals and Methyl-Mercury in Fungi in Markets of Madrid

In this study, 48 different wild and cultivated mushrooms were purchased in local markets in Madrid and provided by trusted specialists from the Mycological Society of Madrid. Cadmium, mercury, and lead were determined by inductively coupled plasma–mass spectrometry (ICP-MS) in samples previously digested in a microwave oven. Methylmercury (MeHg) was determined by liquid chromatography separation (HPLC) combined with ICP-MS after microwave-assisted extraction. Regarding the cadmium and lead contents, all the samples complied with the maximum permitted limits. For mercury, a single sample exceeded the maximum value established in Regulation (EU) 2018/73 for wild mushrooms. In the case of methylmercury, the highest amount represents 13% of the total mercury in one sample. In the rest of the cases, the concentration found was negligible.
