Could a mix of short- and long-term policies be the solution to tackle marine litter? Insights from a choice experiment in England and Ireland
Responsible Partner: CEFAS Date: November 2022 Download: English Description: This study specifically examines the preferences and willingness to pay of English and Irish respondents towards the removal and prevention of marine litter, and the trade-off between different short-term (e.g., beach clean-up) and long-term (e.g., ban on single use plastic) policy actions.
Microplastic occurrence in deep-sea fish species Alepocephalus bairdii and Coryphaenoides rupestris from the Porcupine Bank (North Atlantic)
Responsible Partner: IEO Date: August 2022 Download: English Description:In this study, bathydemersal species Alepocephalus bairdii and Coryphaenoides rupestris from the Porcupine Bank caught between 985 and 1037 m depth were inspected for microdebris. The stomach contents were digested by the alkaline method plus ethanol addition to avoid clogging. A filament of Polyethylene Terephthalate (PET) was found in the stomach of a specimen of A. bairdii, representing 4% of the total sampled specimens of this species (i.e. prevalence in n = 25). However, when considering potential microplastics, the prevalence increased to 28% in both, A. bairdii and C. rupestris. This work provides the first baseline study of microplastic items in fish from such depths in the Atlantic and suggests these species might be used as biomonitors in future research.
The role of cigarette butts as vectors of metals in the marine environment: Could it cause bioaccumulation in oysters?
Responsible Partner: IEO, 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.
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.
Microplastic ingestion by pelagic and benthic fish and diet composition: A case study in the NW Iberian shelf
Responsible Partner: IEO Date: March 2020 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.
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.
