“…For example, it has been shown that multiple Hg-binding proteins (e.g. metallothionein), which is one of the detoxification strategies along with Hg elimination in fish (Pan & Wang, 2012), are less efficient in carnivorous than in herbivorous fish species (Vieira et al, 2017).…”

The hydrothermal compounds massively released into the sea by the geothermal power plant of Bouillante (Guadeloupe, Lesser Antilles) support the growth of sulphur-oxidising bacteria like around black smokers. Opportunistic animals of the bay were previously shown to actively seek and consume the bacterial biofilm. To investigate the role of these bacterial mats in enhancing the transfer of Hg, a highly toxic heavy metal, its concentrations were assessed in sediments, bacteria, and 6 low trophic levels animals from the Bouillante Bay and a Control Site nearby containing only natural sources of Hg. Concentrations of Hg in all samples from Bouillante were greater than those from the Control Site (2 to 627 times higher). A comparison with the Hg concentrations reported in the literature for similar samples types reveals that they are abnormally high in most Bouillante samples. Although bacterial biofilm contained high levels of Hg, the link between bacteria contribution to diet and Hg concentration was more complex than expected, which might be due to interspecific differences in Hg uptake and elimination rates. Species not consuming bacteria (i.e. filter feeders) still presented higher levels of Hg, suggesting that significant amounts of Hg are released along with discharge waters from the Bouillante geothermal plant, and are integrated through diffusion. Differences in Hg concentrations between tissues do not indicate that Hg contained in samples from animals was under the form of MeHg, lowering the biomagnification potential of Hg in the Bouillante Bay trophic food web. Overall, the Bouillante case study emphasises for the first time an important role played by sulphur bacteria mats as a vector of hydrothermal inorganic Hg, and potentially other trace metals emitted in vents area, through dietary pathways.

T HE survival of organisms is threatened with a variety of pollutants and chemical compounds and population growth. Natural phenomena and human activities, especially industrial activities increase contamination of water, soil and air. Population growth leads to increased exploitation of the sea and oceans, thus the consumption of seafood increases. In addition, the main food of the people in some areas is fish. Consumption of fish has numerous benefits to healthy for humans, but the existence of some heavy metals including lead, cadmium, and etc. may cause toxicity to marine organisms. The degree of heavy metal toxicity depends on their chemical form of metals. Some forms of metals are rapidly excreted and do not have the opportunity to be absorbed and stored in body tissues, accordingly they are not very toxic, while some forms of metals are highly toxic and lethal. These forms are slowly excreted from metals and have the ability to be absorbed and accumulated in fish muscles and other organs. Heavy metals cause harmful effects such as carcinogenesis, malformations, damage to the nervous system, damage to the reproductive system and infertility in men, liver failure and cardiovascular disease and so on. Therefore, in this review focused on concentration of heavy metals in fish muscle is essential to ensure the safety of this type of food.

“…The species of fish that are most consumed by the population of this region include: dourada (Brachyplatystoma rousseauxii), filhote (Brachyplathystoma filamentosum), tucunaré (Cichla spp. ), tambaqui (Colossoma macropomum), pirarucu (Arapaima gigas), piranha preta (Serrasalmus rhombeus), and barba chata (Pinirampus pirinampu) [4]. Among these species, dourada, filhote, tucunaré, pirarucu, piranha preta, and barba chata feed mainly on smaller fish, while the tambaqui is omnivorous, feeding principally on aquatic plants but also on small fish [2].…”

This paper presents a slurry sampling method for total mercury determination by graphite furnace atomic absorption spectrometry (GFAAS) in tissue of fish from the Amazon. The tissue samples were lyophilized and macerated, and then the slurry samples were prepared by putting 20 mg of tissue, added to a solution containing Triton X-100, Suprapur HNO 3 , and zirconium nitrate directly in sampling vials of a spectrometer. Mercury standard solutions were prepared under the same conditions as the slurry samples. The slurry samples and the mercury standard solutions were sonicated for 20 s. Twenty microliters of slurry samples were injected into the graphite tube, which contained an internal wall lined with tungsten carbide. Under these conditions, it was possible to thermally stabilize the mercury up to an atomization temperature of 1700 °C. The method was validated by mercury determination in reference materials DORM-4 and DOLT-4. The LOD and LOQ were 0.014 and 0.045 mg kg −1 , respectively, and recovery percentages in relation to the concentration values were certified in the order of 98%.
