Protein, Essential Amino Acid, and Fatty Acid Composition of Five Target Fishery Species of Central Mediterranean Sea.

The protein, essential amino acid, and fatty acid composition of European pilchard (), European hake (), surmullet (), red mullet (), and deep water rose shrimp () from the central Mediterranean Sea were investigated. All the species showed an essential amino acid content of about 50% of total amino acids, while the protein and total fatty acids content varied from 19.9 to 24.

flour: An evaluation for dietary supplementation.

This study assesses the nutritional composition and safety of lab-produced snail flour derived from , an herbivorous pulmonated gastropod mollusc that occupies various trophic levels in food chains. Our analysis focused on key nutritional aspects, including moisture, ash, protein, and fat contents. Contaminant analysis on the powder showed levels below detectable limits for PAHs, PCBs, PBDEs.

Electrochemical remediation of synthetic and real marine sediments contaminated by PAHs, Hg and As under low electric field values.

To date, remediation, protection, and restoration of contaminated sites is a global concern. The current technologies to restore sediments characterized by heterogeneous characteristics, several pollutants, fine grains, and low hydraulic permeability are poorly effective; hence their remediation is still challenging. A promising approach for the sediment's remediation could be the electrochemical route since it is a not-expensive, effective and noninvasive in situ technology.

A chemical remediation technique for a nearly-total removal of arsenic and mercury from contaminated marine sediments.

After decades of industrial exploitation of the coast and consequent contamination of the sites and marine sediments, it became essential to recover the marine ecosystem by remediation methods to remove toxic contaminants. In this work, a remediation method was developed to clean marine sediments contaminated by arsenic (As) and mercury (Hg). The method can be applied to mobile platforms and is based on an environmentally friendly approach designed to minimise further contamination.

Chemical and biochemical responses to sub-lethal doses of mercury and cadmium in gilthead seabream (Sparus aurata).

Specimens of Sparus aurata were exposed to sub-lethal concentrations of Hg and Cd for 25 days and the levels of both metals were investigated in organs and tissues. Bioaccumulation of Hg decreased as follow: gills > kidney > liver > skin > muscle, while the order of Cd bioaccumulation was: liver > kidney > gills > skin > muscle. Immediately after exposure, both metals showed the highest bioaccumulation in gills and skin indicating that these organs are reliable targets for biomonitoring studies after short term exposure.

An integrated approach to characterize deep sediment toxicity in Genoa submarine canyons (NW Mediterranean).

The aim of this study was to evaluate deep sediment toxicity in Genoa submarine canyons (Northwestern Mediterranean), for the first time, by using an integrated approach that combined chemistry and ecotoxicology. Sediments were collected from the main submarine canyons in the Gulf of Genoa (Polcevera and Bisagno) and along the adjacent Western Open Slope. A multi-endpoint ecotoxicological approach was taken by exposing two crustacean larvae (Amphibalanus amphitrite and Artemia sp.

Heavy Metals and PAHs in Meat, Milk, and Seafood From Augusta Area (Southern Italy): Contamination Levels, Dietary Intake, and Human Exposure Assessment.

Heavy metals and PAHs were measured in animal foodstuffs from Augusta-Melilli-Priolo area in order to evaluate the potential human health risk associated to their consumption. All heavy metals were detected in seafood products while most of them were View Article and Find Full Text PDF

Pathways of inorganic and organic contaminants from land to deep sea: The case study of the Gulf of Cagliari (W Tyrrhenian Sea).

In continental margins, canyons appear to act as natural conduits of sediments and organic matter from the shelf to deep basins, providing an efficient physical pathway for transport and accumulation of particles with their associated land-produced contaminants. However, these mechanisms have not been yet sufficiently explored by geochemical markers. The continental slope of the south Sardinia has been used as a natural laboratory for investigating mechanisms and times of transfer dynamics of contaminants from land to sea and from shelf to deep sea through an articulated system of submarine canyons.

Synthesis of water suitable as the MEPC.174(58) G8 influent water for testing ballast water management systems.

Here, we describe the methodologies adopted to ensure that natural seawater, used as "influent water" for the land test, complies with the requirement that should be fulfilled to show the efficacy of the new ballast water treatment system (BWTS). The new BWTS was located on the coast of SW Sicily (Italy), and the sampled seawater showed that bacteria and plankton were two orders of magnitude lower than requested. Integrated approaches for preparation of massive cultures of bacteria (Alcanivorax borkumensis and Marinobacter hydrocarbonoclasticus), algae (Tetraselmis suecica), rotifers (Brachionus plicatilis), and crustaceans (Artemia salina) suitable to ensure that 200 m(3) of water fulfilled the international guidelines of MEPC.
