摘要

地热喷口可能是当地环境中重要的汞(Hg)来源。布扬特(小安的列斯群岛瓜德罗普岛)的地热发电厂人为地增加了海湾浅水区热液的释放量。为了评估这种释放对环境中汞转移的影响,对布瓦兰特海湾和远处对照地点的沉积物、硫氧化细菌和六种不同食性和营养级的动物(海胆、海绵和鱼)体内的汞浓度进行了评估。布伊兰特湾所有样本中的汞浓度都高于对照地点的样本(高出 2-627 倍)。与文献中报道的类似样本类型的汞浓度进行比较后发现,布依兰特大部分样本中的汞浓度异常高,这表明当地受到汞污染,可能是由于热液水释放汞造成的。浅层排放通道的岩石鹅卵石上覆盖着硫氧化细菌垫,这些细菌垫的汞含量很高(13 微克/克)。通过对不同食性的物种进行分析,强调了汞融入布依兰特食物网的两种途径。首先,滤食动物(海绵×3 和双壳贝类×10)不食用细菌垫,鱼类的肝脏/肌肉比率较高,这表明排放水域增加了海洋生物接触溶解无机汞的机会(即水传播途径)。其次,已知摄取排放通道硫细菌垫的机会性动物,如巴氏鱼(Acanthurus bahianus)(×49)和海胆(Diadema antillarum)(×50)体内的汞浓度较高,表明这些化合细菌在当地生物群的汞整合(即膳食途径)和转移中发挥了作用,这为考虑将喷口区作为汞的天然来源提供了启示。

Mercury Accumulation and Transfer in Hydrothermal Coastal Environment: The Case of the Geothermal Plant of Bouillante

Geothermal vents can constitute local significant sources of mercury (Hg) in the environment. The geothermal power plant of Bouillante (Guadeloupe, Lesser Antilles) artificially enhances the release of hydrothermal water in shallow areas of the bay. To assess the impact of this release on the Hg transfer in the environment, Hg concentrations were assessed in sediments, sulphur-oxidising bacteria and six animal species (urchin, sponges and fish) with various diets and trophic levels from the Bouillante Bay and a distant Control Site. Concentrations of Hg in all samples from Bouillante were greater than those from the Control Site (2–627 times higher). A comparison with the Hg concentrations reported in the literature for similar sample types reveals that they are abnormally high in most Bouillante samples suggesting a local Hg contamination imputable to the release of Hg hydrothermal water. Rocky pebbles of the shallow discharge channel are covered by a mat of sulphur-oxidising bacteria presenting high concentration of Hg (13 µg g−1). Through analysis of species with various diet, two pathways of Hg integration into Bouillante’s food webs were emphasised. First, greater Hg concentrations in filter feeders (sponges ×3 and bivalves ×10) not consuming bacterial mats and liver/muscle ratios in fishes suggest that discharge waters enhance the exposure of marine organisms to dissolved inorganic Hg (i.e., waterborne pathway). Second, greater Hg concentrations in opportunistic animals such as the fish Acanthurus bahianus (×49) and the sea urchin Diadema antillarum (×50) known to ingest sulphur-bacterial mats from the discharge channel suggest that these chemosynthetic bacteria play a role in the integration (i.e., dietary pathway) and transfer of Hg in local biota, which enlightens the consideration of vent fields as natural sources of Hg.

期刊介绍: Archives of Environmental Contamination and Toxicology provides a place for the publication of timely, detailed, and definitive scientific studies pertaining to the source, transport, fate and / or effects of contaminants in the environment. The journal will consider submissions dealing with new analytical and toxicological techniques that advance our understanding of the source, transport, fate and / or effects of contaminants in the environment. AECT will now consider mini-reviews (where length including references is less than 5,000 words), which highlight case studies, a geographic topic of interest, or a timely subject of debate. AECT will also consider Special Issues on subjects of broad interest. The journal strongly encourages authors to ensure that their submission places a strong emphasis on ecosystem processes; submissions limited to technical aspects of such areas as toxicity testing for single chemicals, wastewater effluent characterization, human occupation exposure, or agricultural phytotoxicity are unlikely to be considered.
