Effect of seasonality on oxidative stress responses and metal accumulation in soft tissues of Aulacomya atra, a mussel from the South Atlantic Patagonian coast

Long‐ term effects of water quality on the freshwater bivalve Diplodon chilensis (Unionida: Hyriidae) caged at different sites in a North Patagonian river (Argentina)

“…This is in agreement with the increasing sewage disposal together with nutrient and pollutant resuspension during the rainy season, which affects water quality. SOD activity was induced at S2 and S3 compared with S1 in September, in coincidence with high levels of copper in both sites, as was previously observed in natural populations of bivalves from metal-polluted areas (Aulacomya atra: Di Salvatore et al, 2013;Scrobicularia plana: Ahmad et al, 2011) and in caged-bivalves transplanted to areas with multiple pollutants (e.g. metals, pesticides and hydrocarbons; Serafim et al, 2011;Turja et al, 2014).…”

“…In S3, the site with highest concentrations of copper and coliform bacteria, the GSH content was increased in July, coinciding with the peak in fecal bacteria. Increased GSH has been previously reported for bivalves exposed to trace metals (Di Salvatore et al, 2013;Irato, Santovito, Cassini, Piccinni, & Albergoni, 2003) or fecal bacteria . The posterior drop in GSH content registered in September in S2 and S3 could be related to the increase of GST activity in the same period.…”

Biomonitoring Climate Change and Pollution in Marine Ecosystems: A Review onAulacomya ater

“…Furthermore, A. ater has also been used for assessing the presence of cadmium in polluted marine environments on a more than 2000-kilometer-long coastline that extends from Walvis Bay in Namibia to Port Alfred on the coastline of South Africa [37]. In Chile and Argentina, A. ater is often used as a sentinel species to detect the bioaccumulation of pollutants, such as copper or cadmium, or toxic chemicals at different sites or following seasonal variations [14,[41][42][43][44]. It has also been used to study the disruptive effect of the natural estrogen E2 on male and female bivalves [45].…”

“…Up to now, however, most of the biomarkers have been developed using M. edulis as the sentinel species. In the case of A. ater, most of the stress biomarkers have been focused on cellular (phagocytosis, apoptosis, oxygen consumption, oxidative damage, ammonia excretion, and lipid radicals) or enzymatic (acetylcholinesterase, superoxide dismutase, catalase, and glutathione S-transferase) activities [14,33,38,51,52]. Our knowledge of its immune functions also remains limited.…”

Physiological perturbations in juvenile cuttlefish Sepia officinalis induced by subchronic exposure to dissolved zinc

“…Brereton et al, 1973;Watling, 1982;Nadella et al, 2013;Tellis et al, 2014). In the English Channel, Zn is one of the most concentrated dissolved metals, regularly measured at 10 lg l À1 (Lachambre and Fisson, 2007;Sheahan et al, 2007), and worldwide, some studies reported concentrations reaching several hundred lg Zn l À1 in anthropically impacted bays, gulfs and estuaries of South Asia (Srinivasa Reddy et al, 2005;Liu and Wang, 2013) and South America (Amado Filho et al, 1997;Di Salvatore et al, 2013). Moreover, the majority of dissolved Zn in seawater is in a bioavailable physico-chemical form (i.e.…”
