“…This process could represent a risk to the marine community (benthonic and pelagic) and potentially to people when these sediments are highly contaminated. In 1998, the Popular beach was filled with 1.670,000 m 3 of dredged sediments from MDPP and, consequently, high TBT concentrations were found there (240 ng Sn g -1 in 2001 - Goldberg et al 2004, and 175 ng Sn g -1 in 2007-de Waisbaum et al 2010. The results of the present study indicate that 14 years after these activities much of the contaminants have dissipated with very low BT and PAH contamination still present at Popular and adjacent beaches.…”

“…It is surrounded by several sandy and rocky beaches where many intertidal benthic communities can be found and human recreational activities take place. Although BTs Plata port (Goldberg et al 2004;Cledón et al 2006;Bigatti et al 2009;De Waisbaum et al 2010;Albano et al 2013), they have never been measured in the surrounding beaches (except Popular beach for TBT). In addition, TBT contamination have not been assessed in the area since its banning in 2008.…”

The distribution of butyltins (BTs) and polycyclic aromatic hydrocarbons (PAHs) were studied in surface sediments to assess how relevant is Mar del Plata port (Argentina) as a source of contamination to the surrounding environments. Within the port, TBT concentrations ranged from 24.2 to 150 ng Sn g(-1) and PAHs (Σ16) from 180 to 17,094 ng g(-1). At the surrounding beaches, PAHs were detected at low concentrations and TBT concentrations reached 10.9 ng Sn g(-1). Although those low levels indicate that the Port might not be an important source of contamination to the surrounding beaches, the very low TOC content and the coarse grain size of the beaches sediments could explain the sedimentary levels. The results show a reduction in TBT levels in Mar del Plata port after national and international use restrictions of TBT-based antifouling paints.

“…(Jong-Rok et al 2016); hence it is expected to find high bacterial load associated with such contaminants. In fact, in MDPP the above contaminants were historically found in high concentrations (Goldberg et al 2004;Cledón et al 2006;Bigatti et al 2009;De Waisbaum et al 2010;Albano et al 2013;Laitano et al 2015) as well as bacterial load (Pérez Guzzi et al 2006). Thus, it is probable that PO activity is stimulated in barnacles of the port due to pathogens abundance.…”

“…This port can be considered chronic contaminated; many studies report high levels of different contaminants (such as polychlorinated biphenyls, polycyclic aromatic hydrocarbons (PAHs), tributyl tin, etc.) in its sediments over many years (Goldberg et al 2004;Cledón et al 2006;Bigatti et al 2009;Waisbaum et al 2010;Albano et al 2013;Laitano et al 2015). On the other hand, PC, located 3.5 km south from the port, is a quartzite outcrop emerging on a beach that can be considered free of such pollution.…”

Are Mussels Always the Best Bioindicators? Comparative Study on Biochemical Responses of Three Marine Invertebrate Species to Chronic Port Pollution

Bivalves have traditionally been considered good bioindicators due to their sensitivity to pollution, among other features. This characteristic is shared by several other non-bivalve species as well, though studies in this respect remain scarce. This work aims to compare biomarker sensitivity to chronic port pollution among three intertidal invertebrate species with good bioindicator characteristics. Mussels' immunological (phenoloxidase and peroxidases) and biotransformation (glutathione-S-transferase) responses were contrasted against those of limpets and barnacles. The three species under study evidenced activity of all the enzymes measured, although with differences. Barnacle Balanus glandula was the most sensitive species showing pollution modulation of the three enzymes, which suggests that mussels would not always be the best bioindicator species among marine invertebrates depending on the responses that are assessed.

“…This has resulted in the use of toxic paints that have led to serious environmental problems (e.g. tributyltin, TBT; Alzieu 2000, Champ 2000, Goldberg et al 2004). Biofilm formation also plays an important role in bacterial pathogenesis.…”

Many organisms naturally defend themselves against microbial attachment and biofouling in the marine environment. In this study, we investigated microbial fouling on 2 molluscan egg capsules using scanning electron microscopy (SEM), two-photon laser scanning microscopy (TPLSM) with bacterial viability staining and bacterial attachment experiments with the biofilm-forming Pseudoalteromonas sp. S91 in flow chambers. Results indicated that early stage egg capsules of Dicathais orbita (Neogastropoda) are relatively free of surface microorganisms. Egg capsules during the trocophore stage had a regularly ridged microtexture, but as capsules matured, shedding of the outer wall was observed, followed by the extrusion of unidentified droplets, which then accumulated on the capsule surface in association with bacteria. By comparison, the egg capsules of Sepioteuthis australis (Cephalopoda) were found to have an irregular surface with many hills and valleys that accommodate colonization by a variety of microorganisms. At the later stages of development these squid egg capsules become heavily colonized by algal spores. Cross sections of egg capsules revealed that S. australis capsule walls were about 12 times thicker than D. orbita egg capsules. Staining the egg capsules with BacLight™ also revealed a significantly thicker biofilm, with more live and dead bacteria on S. australis capsules than on those of D. orbita (p < 0.05). Flow chamber experiments indicated that the surface of S. australis capsules provided a suitable substrate for colonization by Pseudoalteromonas sp. S91, whereas colonization was significantly less on D. orbita egg capsules after 24 and 72 h (p < 0.01). These experiments indicated that D. orbita egg capsules are better defended against fouling microbes than are the eggs of S. australis. D. orbita appears to use a combination of physical, mechanical and possibly chemical defense mechanisms to reduce fouling on their egg capsules.KEY WORDS: Biofilm · Egg capsules · Mollusc · Scanning electron microscopy · Two-photon laser scanning microscopy · Bacterial attachment Resale or republication not permitted without written consent of the publisherAquat Microb Ecol 47: [275][276][277][278][279][280][281][282][283][284][285][286][287] 2007 an estimated density of 5 × 10 5 prokaryotic cells ml -1seawater (Whitman et al. 1998), sessile invertebrates and algae are exposed to a constant onslaught of potentially detrimental microbes. These include biofilm-forming bacteria along with single-cell diatoms that rapidly settle, attach and form colonies on any surface placed in the marine environment (Davis et al. 1989). The formation of a microbial biofilm promotes the attachment of algal spores, protozoa, barnacle cyprids and marine fungi, followed by the settlement of other marine invertebrate larvae and macroalgae (Maki 2000, Callow & Callow 2002.
