“…contrasts with the one found by other authors (Mosteo et al, 2016;Bighiu et al, 2019), questioning the possible use of the mollusc as an indicator of water pollution, but it reinforces the option of its possible use in the detection of past discharges. On the other hand, it is possible that some of the bacteria identified as mussel-accumulated bacteria are located inside the amoebas.…”

“…The correlation analysis between total bacterial accumulation in mussels and water showed a moderate correlation ( r = 0.74, p < 0.01) for the Sobrón Reservoir and a low correlation ( r = 0.40, p = 0.06) for the Rimer Channel. This contrasts with the one found by other authors (Mosteo et al ., 2016; Bighiu et al ., 2019), questioning the possible use of the mollusc as an indicator of water pollution, but it reinforces the option of its possible use in the detection of past discharges.

“…The microorganisms accumulated inside the mussels include bacteria, viruses and some pathogenic protozoa (Selegean et al ., 2001; Graczyk et al ., 2004; Palos Ladeiro et al ., 2014; Kerambrun et al ., 2016; Mezzanotte et al ., 2016; Mosteo et al ., 2016; Bighiu et al ., 2019). Free‐living amoebas (FLAs) have been found on the shell of the mussel (Bischoff and Wetmore, 2009), and also in extracts of freshwater bivalves from the Ebro River basin using microscopy techniques, but the genus of the FLA was not identified (Mosteo et al ., 2016).…”

Summary To identify the free‐living amoeba (FLA) and amoeba‐resistant bacteria (ARB) accumulated in zebra mussels and in the water in which they are found, mussels were collected at two locations in the Ebro river basin (North East Spain). FLAs and bacteria were isolated from mussel extracts and from natural water. PCR techniques were used to identify the FLAs and endosymbiont bacteria (Legionella, Mycobacterium, Pseudomonas and cyanobacteria), and to detect Giardia and Cryptosporidium. The most frequently found FLAs were Naegleria spp. The presence of Legionella, Mycobacterium and Pseudomonas inside the FLA was demonstrated, and in some cases both Legionella and Pseudomonas were found together. Differences between FLAs and ARB identified inside the mussels and in the water were detected. In addition, Escherichia coli, Clostridium perfringens, Salmonella spp. and Enterococcus spp. were accumulated in mussels in concentrations unconnected with those found in water. The results show the ability of the zebra mussel to act as a reservoir of potentially pathogenic FLAs, which are associated with potentially pathogenic ARB, although the lack of association between microorganisms inside the mussels and in the water suggests that they are not useful for monitoring microbiological contamination at a specific time.

“…Seafood harvested from microbially polluted seawater can expose consumers to these harmful agents, commonly causing gastrointestinal illness, as well as life-threatening conditions. Bivalve mollusks, like mussels and oysters, are particularly risky because as filter feeders, they bioconcentrate environmental pollutants, including antibiotic resistant bacteria in their tissues (Bighiu et al, 2019). Many such filter feeders are often consumed raw or lightly cooked; and consumers might be exposed to pathogenic resistant bacteria, like E. coli and Vibrio parahaemolyticus (Heuer et al, 2009).…”

The integrated study of ocean health and human health is an emerging area of increasing global importance. Growing evidences demonstrate that the health of the ocean and the health of humans have always been and will continue to be, inextricably linked. Our actions toward the oceans will significantly influence the future of the whole planet and, in turn, our own health. The current review of these issues arose from a summer school in San Sebastian (Spain), from 5th to 7th June, 2019. An interdisciplinary group of researchers discussed key risks (e.g., microbial pollution, pharmaceuticals, harmful algal blooms, plastic pollution) and benefits (e.g., bathing waters, recreation, tourism) of the seas and global ocean for humanity; and debated the future priorities and potential actions for a joint Oceans and Human Health research and governance programme in Europe. The aim of this review is to contribute to the emerging scientific agenda on ocean health and human health, as well as coordinate efforts with stakeholders, policy makers and the general public. This agenda operates within the larger context of the upcoming United Nations Decade of Ocean Science for Sustainable Development: 2021-2030, which strives to achieve the Sustainable Development Goals (SDG), including healthy (human) lives and well-being (SDG3) and conserving and sustainably using the oceans (SDG14), among others. In addition to summarizing some of the key risks and benefits, therefore, we describe the governance of oceans and health interactions (especially in Europe), and we finish by proposing a list of elements for potential future research priorities on oceans and human health.

“…Solution of water pollutants polluted by E coli can be treated using the photocatalyst method. The photocatalyst method has proven to be effective in describing heavy metal and bacterial waste in a relatively short and clean time [5][6][7][8]. Photocatalyst material generally used to decompose bacterial and heavy metal waste is Zinc oxide nanoparticles (ZnONPs) [9][10].…”

Synthesis of zinc oxide nanoparticles by pulse laser ablation method has been successed carried out. Synthesis was carried out in aquades medium with a repetition rate variation of 5 Hz, 10 Hz and 15 Hz pulse laser yielding brown colloids. The higher laser repetition rate, the colloidal color will be more dark brown. Characterization of zinc oxide nanoparticles includes UV-Vis, SEM-EDX, FTIR and XRD. The image of SEM shows that zinc oxide nanoparticles have a round shape. Measurement of particle distribution with imageJ software from SEM images showed that ZnO nanoparticles were 23.63 nm, 12.13 nm and 5.59 nm for 5 Hz, 10 Hz and 15 Hz shots. The EDX spectrum analysis results show that only Zn and O atoms in the ZnO nanoparticles colloid are synthesized. FTIR results showed that sprocket ZnO was formed at wave number 457 cm-1 and 545 cm-1. The XRD analysis results also show some peaks known as the ZnO phase. This indicates that ZnO nanoparticles have been formed. The testing of the antibacterial activity of ZnO nanoparticles using a liquid dilution method with nanoparticle concentrations of 40 ppm, 60 ppm and 80 ppm. The test results showed the percentage of degradation of Escherichia coli bacteria at concentrations of 40 ppm, 60 ppm and 80 ppm respectively at 89.60%, 97.76% and 98, 70%.
