“…Labile Cd in sediment was below detection limit in all cases. This finding is in agreement with Mohamed (2008) and also with other researches made in Patagonia (Gil et al, 1999;Vá zquez et al, 2007). Labile Zn, Cu, Pb and Cd values measured in present study were within the range reported for sediments from Nueva Bay by Gil et al (1999), who considered it as slightly polluted.…”

“…Only Cu results were superior to those previously reported by Mohamed (2008) and also to those measured in San Jorge Gulf (Marinho, 2011). In the particular case of Pb, concentrations were similar or even lower than the values reported by Gil et al (1999) and Mohamed (2008). Zn was similar in both studied sites and in the same range found by Mohamed (2008), but higher than the value reported by Gil et al (1999) and Marinho (2011).…”

“…Seawater physico-chemical characteristics and the levels of trace metals in sediment and mussels were also evaluated. Previous studies involving bioaccumulation of trace metals in the ribbed mussel A. atra atra from Nueva Bay have been reported (Gil et al, , 2006Mohamed, 2008) and also levels of trace metals in sediment (Gil et al, 1999;Harvey and Gil, 1988). It is important to remark that not all the sampling sites, the analyzed metals or the employed sediment fraction studied in present work coincide with those monitored in existing literature and/or the methodology is not the same, making difficult direct comparisons.…”

Seasonal variations of trace metals did not appear to influence those of biochemical parameters, which generally showed an opposite trend with higher enzymatic activities in summer when trace metal concentrations were lower. Organisms from Punta Cuevas (control site) showed higher induction of reactive oxygen species production than those from both considered impacted sites, suggesting the possibility of some biochemical adaptation in organisms or a higher modulation of environmental and physiological factors on antioxidant responses than levels of trace metals. This study, which is the first in the area in this matter, showed that seasonal variations of potential biomarkers should be incorporated into interpretation of long-term biomonitoring studies in this marine coastal ecosystem.

“…1). The first report to detect the presence of a point source of pollution and the distribution of metals levels within the bay were carried out between 1994 and 1995 (Gil et al 1997(Gil et al , 1999. The Gonzalito mine operated 107 km from San Antonio Oeste from its opening in the 1960s until its closure in the 1980s, and was involved in extraction of zinc, lead, silver and vanadium.…”
