自1998年以来，定期进行监测计划，以评估位于Constanti（加泰罗尼亚，西班牙）的危险废物焚烧炉（HWI）可能排放的空气化学品对环境和人类健康的影响。2017年，从居住在附近的94名学童（10-13岁）中采集了头发样本，并测定了11种微量元素（As，Be，Cd，Cr，Hg，Mn，Ni，Pb，Sn，Tl和V）的水平。结果表明，土壤中Pb、Hg、Ni、Sn、Mn、Cr的含量顺序为：Pb > Hg > Ni > Sn > Mn > Cr。反过来，As，Be和Tl未被检测到，而Cd和V仅在少数样品中被发现。一些金属水平显着，正相关。根据性别和居住地区的不同，也注意到了一些显著差异。最后，微量元素的水平随着时间的推移而波动。与基线研究（1998年）中获得的浓度相比，铬和铅显示出显著下降。根据目前的结果，从人类健康影响的角度来看，HWI的金属排放并不相关，因为其水平与其他污染地区报告的水平相似，甚至更低。
Since 1998, a monitoring program is periodically performed to assess the environmental and human health impact of air chemicals potentially emitted by a hazardous waste incinerator (HWI) located in Constanti (Catalonia, Spain). In 2017, samples of hair were collected from 94 schoolchildren (aged 10-13 years) living nearby and the levels of 11 trace elements (As, Be, Cd, Cr, Hg, Mn, Ni, Pb, Sn, Tl and V) were determined. The concentrations showed the following descending order: Pb > Hg > Ni > Sn > Mn > Cr. In turn, As, Be and Tl were not detected, while Cd and V were found only in a few samples. Some metal levels were significantly, positively correlated. Some significant differences were also noticed according to the gender and the specific zone of residence. Finally, the levels of trace elements showed fluctuations through time. Cr and Pb showed a significant decrease in comparison to the concentrations obtained in the baseline study (1998). According to the current results, metal emissions from the HWI are not relevant in terms of human health impact since their levels were similar and even lower than those reported in other contaminated areas.
