“…to 49.1 (median=40 items/km², which corresponds to the lowest annual mean values for the areas investigated in the present study (GoL and CI). In comparison with other studies carried out in the Mediterranean region (Alvito et al, 2018;Ioakeimidis et al, 2014), the densities in the western basin were found to be in the same range as several areas of the eastern Mediterranean, such as the Aegean Sea (416 to 1.211 items/km²), the Black Sea (291 ± 237 items/km²) and above the densities found in the Levantin basin (24 ± 28 items/km²).…”

Seafloor litter has been studied both on the continental shelves (by trawling during 24 years) and in canyons (by ROV) of the French Mediterranean sea Water (FMW). On the continental shelf, mean densities range from 49.63 to 289.01 items/km2. The most abundant categories were plastic, glass/ceramics, metals and textiles. Trend analysis shows a significant increase in plastic quantities during the study period. Plastics accumulate at all depths, with heavier items being found in deeper areas, while the continental slope-break appears as a clean area. The spatial distribution of litter revealed the influence of geomorphologic factors, anthropic activities, shipping route, river inputs. All the canyons are affected by debris but coastal canyons (Ligurian Sea and Corsica) were more impacted than offshore canyons in the Gulf of Lion. The FMW appears to be highly polluted with regard to values found in other areas, but lower than those observed in the Eastern Mediterranean. Highlights ► Time series of 23 years of seafloor litter data collected from bottom trawl surveys. ► Use of three years of litter data collected in canyons from Remotely Operated Vehicle. ► Marine litter assessment for the Gulf of Lion and eastern Corsica areas. ► analyses allowing the identification of hot spots and temporal trends. ► On the continental shelf, annual mean densities range from 49.63 to 289.01 items/km 2. ► The most common litter categories are plastics, glass/ceramic, metals and textiles.

“…As with all the other studies performed in the Mediterranean Sea, plastic accounts for the largest part of sea floor litter (Alvito et al, 2018;García-Rivera et al, 2017). This threat originates mainly from single use plastics such as bags, food packaging and synthetic ropes and strapping, most of them of telluric origin.…”

“…During the 2015, the total fishery production accounted for 2964 tons with Italy as first country, catching the 52% of the total capture (http://appsso.eurostat.ec.europa.eu/nui/submitViewTableAc tion.do). In the Central Mediterranean Sea, the silver scabbardfish is the third species in term of contribution (%) to long-line fishery landings (Alvito et al, 2018). Indeed, this fish species is largely consumed at the local scale level and commonly commercialized as fresh fish in the Italian markets (Bottari et al, 2019).…”

First molecular detection of the parasites Molicola uncinatus and Hepatoxylon trichiuri (Cestoda: Trypanorhyncha) infecting the silver scabbardfish Lepidopus caudatus from the Central Mediterranean Sea: Implications for the seafood quality and safety

Trypanorhynch tapeworms are marine heteroxenous parasites, involving sharks and rays as definitive hosts, invertebrates (i.e. crustaceans) as first intermediate hosts, and various teleost fishes as intermediate/paratenic ones. The massive presence of Trypanorhyncha larval forms in the flesh or body cavity of the fish hosts reduces their market value, making them unappealing to consumers, or causing discards of fish products. The identification of merocercoids (N = 100) of Molicola uncinatus and plerocercoids (N = 46) of Hepatoxylon trichiuri parasitizing the silver scabbardfish, Lepidopus caudatus, from the Central Mediterranean Sea (off Malta coast), was obtained, for the first time, by using sequences analysis of the complete small subunit (ssrDNA) and the partial large subunit (lsrDNA) ribosomal RNA gene loci. The Bayesian Inference from the concatenated sequences obtained at the two gene loci showed that the individuals of M. uncinatus and H. trichiuri clustered, respectively, in two well distinct and supported phylogenetic lineages, corresponding to the two cestode species. High prevalence (P) and mean abundance (MA) values were observed in the infection with merocercoids of M. uncinatus (P = 100%, A = 28.81), with the ventral musculature of the silver scabbardfish as the most parasitized site. Plerocercoids of H. trichiuri were found to infect only the mesenteries, attached to various fish tissues, with a mean abundance rate of 1.28. Even if harmless to humans, a heavy parasitic load with larval stages of Trypanorhyncha, particularly in the edible part of the silver scabbardfish (as here reported for merocercoids of M. uncinatus), can compromise the appearance of the fish-food, making it repugnant and unappealing for the final consumer. It has been also discussed that when managing the risk related to parasites affecting the fish quality and safety of fisheries products, the fishing ground where the life cycle of those parasites takes place should be also taken into account, as it would include the ecological drivers of the infection with those parasites. This wider ecological approach would be of help to the Food Business Operators (FBOs), gathering knowledge useful to manage fisheries in a wide "One-Health" perspective, aware of sustainability, quality and consumer safety aspects of seafood production.

“…If continually left will be bad to the quality of the river. According to the Palar (1994) that if the amount of heavy metals enter into the human body to the amount of the excess, then it will turn out to be toxic to the body function and affect the life of the life that was in the river [12].…”

Systems of waste management in Padangsidimpuan City is an open dumping system. The location of the Padangsidimpuan City landfill is carried out at the Batu Bola TPA located in Batu Bola Village which is 120 meters from the Batang Ayumi river flow. Continuous landfill in the landfill produces pollutants in the form of leachate. Leachate contains organic materials and heavy metals. Heavy metals that are often found in leachate water are Iron (Fe) cadmium (Cd) and Zinc (Zn). This research aims to know the quality of the water of the Batang Ayumi river in terms of the content of heavy metals Cd, Zn, and Fe. This research uses descriptive exploratory method by conducting a survey first. The determination of the sampling location using purposive sampling method at four stations specified. River water sampling is carried out twice, before and after rain. This research uses an Atomic Absorption Spectrophotometer tool. The data obtained were analyzed by comparing research data with water quality standards based on PP. No. 82 of 2001 to look at the conditions of the heavy metal pollution of Cd, Zn and Fe. The results of this study showed that the average concentration of the metal content Cd, Zn and Fe werw below the specified quality threshold, namely the concentration of metal Cd of all stations is 0.0009 mg/l, a concentration of metal Fe is 0.03 mg/l, and concentration of Zn metal is 0.0002 mg/l.
