Inorganic arsenic (iAs) is considered to be a human carcinogen. In this paper, total (As) and iAs contents of 215 food products and drinks (i.e., seafood, fruits and vegetables, meat products, oils and fats, rice and rice products, seasonings, and alcoholic drinks) marketed in Catalonia (Spain) were quantified by inductively coupled plasma-mass spectrometry. The analytical method described was used for different food products, obtaining feasible results without the need to couple LC-ICP-MS for iAs. Daily As and iAs intakes for the average adult Catalan consumer were estimated at 354 and 6.1 μg/day/person, respectively, using consumption data from the Catalan Nutrition Survey (ENCAT). The highest As content was found in seafood, contributing 96% of dietary As intake, whereas rice presented the highest iAs values, corresponding to 67% of dietary iAs intake. As cooking process may affect iAs content, boiled rice was evaluated, showing an iAs reduction (up to 86%) when using higher water volumes (30:1 water/rice ratio) than those used in previous studies. This iAs exposure was slightly below the exposure risk range stated by the European Food Safety Authority (0.3-8 μg/kg of body weight/day), although the possibility of a risk to the population with high rice consumption cannot be excluded.
无机砷 (iAs) 被认为是一种人类致癌物。在本文中,通过电感耦合等离子体质谱法定量测定了加泰罗尼亚(西班牙)市场上 215 种食品和饮料(即海鲜、水果和蔬菜、肉类产品、油脂、大米和大米制品、调味料和酒精饮料)中的总砷 (As) 和 iAs 含量。该分析方法可用于不同的食品,无需将 LC-ICP-MS 用于 iAs 即可获得可行的结果。使用加泰罗尼亚营养调查 (ENCAT) 的消费数据,估计普通成年加泰罗尼亚消费者的每日砷和 iAs 摄入量分别为 354μg/天/人和 6.1μg/天/人。海产品的砷含量最高,占膳食砷摄入量的 96%,而大米的 iAs 含量最高,占膳食 iAs 摄入量的 67%。由于烹饪过程可能会影响 iAs 含量,因此评估了煮米饭,当使用比以往研究更高的水量(水/米比为 30:1)时,iAs 含量会降低(最高可达 86%)。这一 iAs 暴露水平略低于欧洲食品安全局规定的暴露风险范围(0.3-8μg/kg 体重/天),尽管不能排除高摄入量人群面临风险的可能性。
