“…Although metals have a natural origin, they can also have anthropogenic origins, such as mining and smelting operations, refining and electroplating, dye and paint manufacture, and fossil fuel burning [ 12 ]. Organisms that are both in contact with sediment and water, such as polychaetes, are more conducive to accumulating these elements and suffering from the physical and chemical changes that occur in their environment [ 13 ]. Increased reactive oxygen species, the inhibition of antioxidant enzymes, and decreased fecundity and mortality are some of the various impacts that metals have on these organisms [ 14 , 15 , 16 ].…”

“…Bouraoui et al [ 18 ] also observed the induction of oxidative stress biomarkers in different body regions of the polychaete Hediste diversicolor when exposed to Cu. A field study carried out along Ria de Aveiro demonstrated that various metals (chromium (Cr), nickel (Ni), copper (Cu), lead (Pb), cadmium (Cd), mercury (Hg)), and Arsenic (As)) accumulated in D. neapolitana, leading to cellular damage and increased antioxidant and to the biotransformation of enzyme activity [ 13 ]. The same study revealed that the elements that were analysed predominantly bioaccumulated in the insoluble fraction present in the precipitated form or in the fraction that is bound to membranes, thus not causing toxicity to organisms [ 19 ].…”

Polychaetes are known to be good bioindicators of marine pollution, such as inorganic contamination. Major and trace elements are commonly present in sediment and may be accumulated by polychaetes such as the tubiculous Diopatra neapolitana. In this study, D. neapolitana individuals were collected in the autumn, winter, spring, and summer of 2018/2019 from the Ria de Aveiro lagoon (western Portugal) to understand how seasonality influences element accumulation. The impact of the interaction of seasonality and elements on oxidative status, energy metabolism, and oxidative damage was also assessed. The obtained results showed that the activity of the antioxidant enzymes catalase, glutathione S-transferases, and non-protein thiol levels were higher in summer and that superoxide dismutase, lipid peroxidation, and electron transport system activity increased in winter. The lowest glycogen levels were observed during spring, and protein carbonylation was the highest during autumn. These results could mainly be related to high temperatures and the bioaccumulation of Al, As, Mn, and Zn. Energy-related parameters increased during spring and autumn, mainly due to the bioaccumulation of the same elements during spring and summer. Lipid damage was higher during winter, which was mainly due to salinity and temperature decreases. Overall, this study demonstrates that seasonality plays a role in element accumulation by polychaetes and that both impact the oxidative status of D. neapolitana.

“…In the Ria de Aveiro, metal(loid) bioaccumulation has been investigated in many taxa above bivalves, such as foraminifera (Martins et al, 2010;), polychaetes (Freitas et al, 2012bPires et al, 2017), gastropods (Cardoso et al, 2013) and crustaceans (D'Ambrosio et al, 2013); among vertebrates, several fish species and their parasites have been studied (as examples Cid et al, 2001;Eira et al, 2009;Araujo et al, 2015). No data are currently available for bird species.…”

The present work was carried out in the Ria de Aveiro Lagoon (Portugal) to better understand the dynamics driving the bioaccumulation processes in edible bivalves, namely in the Manila clam Ruditapes philippinarum. For the first time, a holistic approach was applied, collecting data on sediment physico-chemical characteristics and its contamination, geochemical speciation and metal(loid) bioaccumulation in clams, from three exploited areas of the lagoon (Costa Nova, Torreira, Ílhavo). The Ria de Aveiro Lagoon is part of the Natura 2000 network, has the designation of Special Protection Area (SPA), contains Sites of Community Importance (SCI), it is protected by the EU Birds Directive (79/109/CEE) and includes a natural reserve in its northern part. Specifically concerning the metal(loid) occurrence, the monitoring and the identification of contaminated sites in protected areas are priorities, to improve the biodiversity conservation efforts and to ensure the correct management of natural resources. Results showed that multiple driving forces interacted together to determine site-specific impacts, resulting in different risks at local scale for the transferring of the metal(loid)s to the trophic chain. Hydrodynamics played a major role driving the occurrence of depositional or ablative sites, influencing the granulometric composition of sediments and their contamination; metal(loid) chemical forms were then determinated by multiple factors like pH, redox potential and organic matter content. The geochemical speciation data showed that the Ílhavo area should be considered the most dangerous in terms of clam consumption, since in case of environmental changes, possible conversion of the elements from the potentially bioavailable forms to the bioavailable ones can occur. Moreover, bioaccumulation processes in Manila clam were observed for Cd, Zn and especially As, the latter representing serious risk for consumer safety throughout clam consumption.

“…Such enrichment can also lead to sulphide accumulation, altering infaunal communities through toxicological effects and exacerbation of hypoxia (Heilskov and Holmer 2001;Wu 1995). Furthermore, sediment contamination is not restricted to organic enrichment and occurs through pollution and industrial effluents containing polycyclic aromatic hydrocarbons, sulfides, coppers and other chemicals (Hoos 1975;Turner 2019;Yunker et al 2002), with negative impacts on infaunal communities (Pires et al 2017;Pocklington and Wells 1992;Waldichuk 1966).…”

“…Invertebrates have been used to develop ecological theories on organismal responses to disturbance (Cowie et al 2000;Gerwing et al 2017a;Pearson and Rosenberg 1978), and are employed in both monitoring and assessing human impacts on natural ecosystems (Borja and Muxika 2005;Gerwing et al 2018a;Hereward et al 2017;Muxika et al 2005;Pearson and Rosenberg 1978). In addition to monitoring applications, marine benthic invertebrates support commercial fisheries, both by serving as dietary sources for fish and as industrial bait (Davis et al 2014;Kritzer et al 2016;Pires et al 2017). Therefore, studying invertebrates is a pro-active strategy to detect disturbances before productivity of commercial fisheries is impaired (Ozdemir et al 2011;Pinto et al 2009).…”

Estuarine ecosystems are degraded through anthropogenic development, leading to reduced habitat suitability for biological communities. The Skeena River estuary (British Columbia, Canada) is undergoing passive reclamation from historical salmon canneries and pulp mills, while localized disturbances continue at present. To reveal both current impacts and the trajectory of passive reclamation from historical activities, the intertidal mudflat surrounding the longest operating salmon cannery, Cassiar Cannery, within the Skeena estuary was surveyed. Nutrient availability (chlorophyll a concentration/organic matter content), sediment variables (particle size, water content, penetrability, woody debris/macroalgae cover, apparent redox potential discontinuity depth), and infaunal community composition varied spatiotemporally, and suggest that an old dock may be influencing the infaunal community given the abundance of disturbance indicating taxa below the dock. However, with populations of amphipods, mobile polychaetes, and a complex community structure, the mudflat as a whole appears to be relatively healthy. Therefore, cessation of historic activities has allowed for passive reclamation to a reasonably unstressed state, though a threshold of recovery may exist for intertidal mudflats beyond which passive reclamation will not be effective.
