2017年，在加泰罗尼亚（西班牙）进行了一项监测研究，以分析广泛消费的食品中砷（As），镉（Cd），汞（Hg）和铅（Pb）的浓度，以及无机As（InAs）和甲基汞（MeHg）的浓度。对按年龄分类的不同人口群体的健康风险进行了估计。在比较过去17年中进行的当前和以前的研究结果时，观察到这些元素的饮食暴露持续减少。这种减少与食物中As、Cd、Hg和Pb浓度的降低以及饮食习惯的改变有关。没有一个成人组超过了欧洲食品安全局建立的安全阈值，但幼儿、婴儿和儿童超过了镉和甲基汞的PTWI。最大的镉和甲基汞的摄入量对应于婴儿，是由于消费的墨鱼和鳕鱼。这些物种的消费量应减少到每周两到三次，并与其他非捕食性物种的摄入量相结合。总之，目前的结果表明，有必要进行进一步的定期调查，特别是注意镉和甲基汞的摄入量的趋势。
In 2017, a monitoring study was conducted in Catalonia (Spain) to analyse, in widely consumed foodstuffs, the concentrations of arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb), as well as those of inorganic As (InAs) and methylmercury (MeHg). Health risks were estimated for various population groups, classified according to age. A continued reduction of dietary exposure to these elements was observed when comparing the results from the current and previous studies performed during the last 17 years. This reduction would be associated to a decrease of As, Cd, Hg and Pb concentrations in food, as well as by changes in dietary habits. None of the adult groups exceeded the safety threshold established by the EFSA, but toddlers, infants and children exceeded the PTWI for Cd and MeHg. The greatest intake of Cd and MeHg corresponded to infants, being due to the consumption of cuttlefish and hake. The consumption of these species should be reduced to two or three weekly portions, being combined with the intake of other non-predator species. Anyhow, the current results indicate that is necessary to conduct further periodical surveys, paying special attention to the trend in the intake of Cd and MeHg.
