“…Coasts, bays and semi-closed basins, especially those influenced by large rivers flowing through highly industrialised sites, represent priority marine areas subjected to risk of Hg pollution (Sprovieri & Pirrone 2007). In particular, as discussed by Covelli et al (2007), fluvial suspended particulate matter (SPM) plays an important role in the transport and dispersion of trace metals in marine environments. Data published by Pirrone et al (2001) on total anthropogenic mercury emissions in the Mediterranean region show that France is the leading Hg emitter with 21.4%.…”

“…On the other hand, in the Adriatic Sea, a number of industrial sites, located on the coastal zone, produced evident rise of atmospheric mercury levels (Sprovieri & Pirrone 2007). Also, Rajar et al (2007) and Covelli et al (2007) reported that mainly the rivers Po and Isonzo are responsible for significant input of particulate Hg in Adriatic seawaters. Moreover, as discussed by Foucher et al (2009), the well-known Idrija mercury mine (western Slovenia), which closed in 1995 after a long period of activity, has been one of the largest Hg mining area worldwide.…”

Concentrations of Hg were determined in tissues (muscle, heart, kidney, lung and liver) of two cetacean species (Stenella coeruleoalba and Tursiops truncatus) stranded along the Italian coasts during the period 2000-2009 and compared with those previously reported by other authors from different areas of the Mediterranean basin. The highest concentrations of Hg were found in liver samples of both species (8.4-1752 mg·kg −1 dry weight for S. coeruleoalba and 9.6-1404 mg·kg −1 d.w. for T. truncatus). Statistically significant dissimilarities of Hg concentrations were recorded in muscle and liver tissues of S. coeruleoalba stranded in different geographical areas of the Mediterranean Sea as apparent direct response to uneven impacts of Hg pollution in the basin. A noteworthy outcome was that cetaceans stranded on the French coasts showed significantly higher levels of Hg contamination than those from other Mediterranean areas while the eastern part of the basin evidences the lowest Hg concentrations in the studied organisms. Moreover, the results of this study tentatively suggest the existence of different sub-populations of the two species in the basin.

“…The Idrija Hg mine operated for nearly 500 years, until it definitively closed in 1996. Nevertheless, Hg is still being delivered through river flow to the Gulf of Trieste and the adjacent Marano and Grado Lagoon (Covelli et al, 2007). Within the lagoon Hg contents range from 2.34 to 10.6 µg g -1 and progressively decrease westwards.…”

In the pres ence of metal stress, plants can resort to a series of tol er ance mech a nisms. There fore field studies should be under taken in order to eval u ate the real role of these mech a nisms in stress cop ing. The aim of this paper was to clar ify the bio chem i cal pro cesses behind mer cury tol er ance in Ha lim i one por tu la co ides (L.) Ael len (Caryo phyll ales: Cheno po di a ceae) col lected in a mer cury con tam i nated salt marsh. Dif fer ent frac tions of mer cury were sep a rated: buffer-sol u ble (mainly cyto solic) and insol u ble mer cury (mainly asso ci ated with mem branes and cell walls). The amounts in each frac tion of metal were com pared and related to metal dis tribu tion within plant organs. Pro tein-mer cury com plexes were iso lated and ana lysed for their thiol con tent in order to assess wether the tol er ance of this salt marsh plant was asso ci ated with the induc tion of metal che lation by phy to chel a tins. Over all, the mer cury tol er ance strat e gies of the plant are likely to involve root cell wall immo bi li za tion as a major mech a nism of metal resis tance, rather than metal che la tion in the cyto solic fraction. Nev er the less, phy to chel a tins were dem on strated to che late mer cury under envi ron men tal expo sure.
