Title: Monitoring floating microlitter in offshore waters by manta-trawl (collaboration with iFADO project)
Responsible Partner: IEO Vigo
Date: September 2021
Download: Link 
Description: In collaboration with iFADO project 10 samples from Galician offshore waters (NW Iberian Peninsula) were collected by means of a manta-trawl net for microlitter categorization. The results obtained in this work suggest a moderate microlitter density in both coastal and offshore stations. The average of item density for the whole sample collection was 0.0089 ± 0.0091 item/m2 or 0.0446 ± 0.0455 item/m3. Fragments found were abundant in both coastal and offshore stations and were mainly composed by particles with sizes smaller than 1 mm and predominance of green colour.

Title: The role of cigarette butts as vectors of metals in the marine environment: Could it cause bioaccumulation in oysters?
Responsible Partner: IEO Vigo, CEDRE
Date: August 2021
Download: Link to publication
Description:Tobacco is a well-documented threat to human health. However, its environmental impact has only recently been considered. Metals can interact with cigarette butts (CBs) being transported in the marine environment and reaching organisms. To understand this mechanism, a series of metal(loid)s were analyzed in cigarette filters (virgin, artificially smoked, leached in seawater and aged in beach and harbour) as well as in artificially contaminated oyster tissues. Smoked filters showed higher levels of metals compared to the virgin ones showing enrichment factors up to 90, probably associated with tobacco metal content. Once the CBs are delivered to the environment, metals can be leached to seawater until reaching equilibrium, which may be dependent on initial metal levels in the water. Copper was the element with the highest percentage of desorption (91 ± 3%) while strontium showed the lowest percentage (40 ± 0%). CBs revealed a great capacity to accumulate metals from the environment when weathered in contaminated areas. A chemical impact derived from CBs contamination might exist as they serve as a carrier for metals in the marine environment. The release of metals from CBs or the ingestion of metal loaded CBs may pose a toxicological risk for marine organisms via accumulation in their tissues.


Title: Microplastic ingestion by pelagic and benthic fish and diet composition: A case study in the NW Iberian shelf
Responsible Partner: IEO Vigo
Date: March 2021
Download: Link to publication
Description: This study evaluated the incidence of microplastics in the digestive tract contents of four fish species: Engraulis encrasicolus, Sardina pilchardus, Callionymus lyra and Mullus surmuletus. Alkaline digestion (10% KOH) was used to degrade the organic matter. The percentage of fish with microplastics was 78% (88% fibres, 12% fragments). The main types of polymers identified by Raman spectroscopy were polyethylene and polypropylene. The diet of the four species was also studied and two feeding types were determined: plankton-feeders and benthic-feeders. The effect of a set of biological variables (Length, Fullness index, Fulton’s condition factor and Feeding type) on the number and size of microplastics ingested was studied using Generalised Additive Models (GAMs). A significant increase in the number of microplastics with increasing length was observed. No significant effect of trophic variables (fullness index and feeding type) on the number and size of microplastics was found.


Title: Ingestion of plastic debris (macro and micro) by longnose lancetfish (Alepisaurus ferox) in the North Atlantic Ocean
Responsible Partner: IEO Vigo
Date: January 2020
Download: Link to publication
Description: This study evaluates the ingestion of plastic marine debris (macro and micro plastics) by a piscivorous predator, Alepisaurus ferox Lowe (1833). A total of 27 specimens were captured in 2015 and 2016 in the North Atlantic (around 34º–36º N and 10º–16º W) and their stomachs were dissected and inspected for plastic elements. Macroplastic particles were found in 37% of fish, with an average weight of 0.46 ± 1.14 g with film being the most abundant category (60%). The main polymers characterized were Polypropylene (PP) and Polyethylene (PE). Microplastics were found in 74% of the stomachs, with item values per individual ranging from 0 to 16, with an average value of 4.7 ± 4.8 items per stomach. Only microfibers and fragments were observed, with microfibers (85 %) being the dominant type.


Title: Will COVID-19 Containment and Treatment Measures Drive Shifts in Marine Litter Pollution?
Responsible Partner: ARDITI, OSPAR and DRAAC
Date: August 2020
Download: Link to publication
Description: This opinion article underlines the authors’ concern about the mass use of disposable masks and other personal protective equipment without a concerted strategy for their recycling, which could result in an increase of litter entering the marine ecosystems. The paper intends to act as a call on policy makers and international organizations to maintain their goals in plastic reduction in the oceans and to adapt their litter monitoring programs so as to identify litter from the use and disposal of personal protective equipment.
