“…Mn as a trace metal essential for life showed the same seasonal evolution as other trace metals, which are more involved in biochemical activities and required by biota for various biochemical processes [45]. Mn concentrations of all DSP positive samples showed a similar decreasing trend from January to June, which is in accordance with the seasonal pattern demonstrated in concentrations of Cd, Pb, Zn, Cr, Cu, and Ni investigated in the first six months of 2011 during DSP toxicity of mussels from the Bay of Mali Ston by Ujević et al [50].…”

“…As the comparison of Mn concentrations measured in DSP positive and DSP negative samples of mussels from the Bay of Mali Ston revealed higher Mn concentrations in 87% of DSP positive samples, it could be assumed that there is a connection between the measured Mn levels and the occurrence of biotoxins GYMs and SPXs. Mn showed the same connection with the occurrence of phycotoxins GYMs and SPXs in DSP positive samples of blue mussels from the Bay of Mali Ston during DSP toxicity episodes in 2011, just as did Zn, Cu, Cd, and Ni, which showed higher levels in more than 70% of DSP positive samples as it was reported in the study of Ujević et al [50].…”

“…The possible explanations for the role of Mn in the occurrence of GYMs and SPXs in analysed DSP positive samples from the Bay of Mali Ston may be that the increase of Mn content in the seawater could have either affected metabolic pathways in phytoplankton cells and enhanced the production of marine biotoxins [4], or that when bioaccumulated in shellfish tissue, it could have facilitated the transport of biotoxins and their accumulation in shellfish cells [50].…”

Diarrhetic Shellfish Poisoning (DSP) toxicity was revealed in the Mediterranean blue mussel (Mytilus galloprovincialis) from the Bay of Mali Ston, in the south part of the Eastern Adriatic Sea, through the Croatian National Monitoring Programme in the period from January until June of 2011. A survey of DSP toxicity within the frame of regular controls carried out through the mouse bioassay (MBA, at the time the official method for DSP toxins) demonstrated that in some incidents, positive MBA, which manifested by the atypical symptomatology of the animals, dominated. Additional studies were done to explain the atypical results of the conducted biological tests at the time. In the current study, the bioaccumulated manganese concentration in the soft tissues of mussels was measured to investigate its influence on the MBA results. In both DSP negative and DSP positive samples, which were prepared for the analysis according to the modified US EPA 3052 method, the concentration of the bioaccumulated manganese was performed on the atomic absorption spectrometer using flame atomic absorption spectroscopy technique. The analysis revealed higher concentration of manganese in 87% of DSP positive samples and the expressed per wet weight ranged from 0.15 to 5.38 mg kg−1. The mean concentration of manganese for all DSP positive samples was 1.78 mg kg−1, while for DSP negative samples, it was 48% lower (0.93 mg kg−1). The highest concentration of manganese in DSP positive samples was measured in February 2011. Since the low concentrations of lipophilic biotoxins gymnodimines (GYMs) and spirolides (SPXs) were also detected in the analysed DSP positive samples in the parallel studies, the results obtained in this study suggest future investigations of the connection between the concentration of manganese and lipophilic biotoxins.

“…These molluscs are widely used in coastal monitoring programmes and pollution assessment studies as they are sessile organisms with a worldwide geographical distribution. They are filter-feeders with a slow rate of detoxification and they have an ability to accumulate many different toxic contaminants (Bogdanović et al, 2014;Ujević et al, 2015). EC regulation 854/2004 and directives issued by the EPCEU (EPCEU, 2004b) on 29 April 2004 stipulate specific rules for the organisation of official controls on products of animal origin intended for human consumption.…”

The European Commission (EC) regulation no. 854/2004 requires a systematic monitoring of chemical and microbiological contaminants in live bivalve molluscs, live echinoderms, live tunicates and live marine gastropods for human consumption through surveillance plans to be implemented in all European Union (EU) countries.A consortium of five Adriatic countries was set up in the framework of the Instrument of Pre-accession Assistance Adriatic Cross-border Cooperation Programme (IPA Adriatic CBC) 2007- 2013 with the aim of collecting data and distribute information on harvesting and production in mollusc areas. A web-based geographical information system (GIS) application was developed to support the partners to manage data and to make these data available to final users, policy makers and to risk assessors. The GIS for the Strengthening of Centres for Aquaculture Production and Safety surveillance in the Adriatic countries (CAPS2) is divided into two levels, the national and the supranational one, and it distributes spatial and epidemiological information coming from various data acquisition and management sites. The great innovation is the possibility for each country to use online drawing, modifying and change of the geographic areas according to national surveillance needs. Currently it hosts data coming from about 230 production and relay areas with more than 29,478 laboratory tests performed on collected samples since August 2014. Data collected are used by each national competent authority to classify production or relay areas according to the EC regulation mentioned and to conduct risk assessment studies to evaluate the level of consumers’ exposure to contaminants in the consumption of bivalve mollusc products.

“…Currently, few studies are available regarding the concentrations of PTE in the various organisms of the Adriatic Sea (Gavrilović et al , 2004; Kljaković-Gašpić et al , 2004, 2007; Bogdanović et al , 2014; Bille et al , 2015; Ujević et al , 2015). Our recent papers (Komar et al , 2014, 2015a, b) mainly focused on PTE accumulation and their speciation in recent marine sediments in Makirina Bay (Central Adriatic).…”

The presence of potentially toxic elements (PTE) was determined in different tissues of five selected marine organisms. The As, Cd, Cu, Mn, Mo, Ni, Pb and Zn concentrations were measured in the seagrass Cymodocea nodosa, the green alga Cladophora echinus, the red alga Gelidiella lubrica, the marine topshell Phorcus turbinatus and the littoral crab Carcinus aestuarii, as well as in seawater from Makirina Bay. The levels of As, Cd, Cu, Mn and Zn in the biota were found to exceed those in previously analysed sediments, indicating the bioaccumulation of these PTE. The biota-sediment accumulation factor (BSAF) and concentration factor (CF) varied among different organisms. As regards the five selected species, C. nodosa, C. echinus and G. lubrica proved to be the strongest accumulators of Mn, while P. turbinatus and C. aestuarii showed a high capacity to accumulate As, Cd, Cu and Zn. These species can be considered as good ecological indicators in the assessment of PTE pollution in marine littoral environments.
