The present paper provides an overview of mercury studies performed in the Mediterranean Sea region in the framework of several research projects funded by the European Commission and on-going national programmes carried out during the last 15 years. These studies investigated the temporal and spatial distribution of mercury species in air, in the water column and sediments, and the transport mechanisms connecting them. It was found that atmospheric concentrations of Hg compounds, particularly oxidised Hg species observed at five coastal sites in the Mediterranean Sea Basin, are significantly higher compared with those recorded at five coastal sites distributed across N Europe, most probably due to natural emissions. Hg levels in water are comparable to other oceans. Anthropogenic and natural point sources show locally limited enrichments, while natural diffusive sources influence Hg speciation over larger areas. Results and statistic comparison of mercury species concentrations within Mediterranean compartments will be presented and discussed.
本论文概述了在过去 15 年中，由欧盟委员会资助的几个研究项目和正在进行的国家计划框架内在地中海地区进行的汞研究。这些研究调查了汞物种在空气、水柱和沉积物中的时空分布以及连接它们的传输机制。结果发现，与分布在北欧的五个沿海地点记录的相比，地中海盆地五个沿海地点观测到的 Hg 化合物，特别是氧化态 Hg 物种的大气浓度要高得多，这很可能是由于自然排放造成的。水中的 Hg 水平与其他海洋相当。人为和自然点源显示局部有限的富集，而自然扩散源则在更大的区域内影响 Hg 的形态。将介绍和讨论地中海各隔室中汞物种浓度的结果和统计比较。
