Microplastic (MP) pollution has become a global concern due to its potential impacts on the environment, ecosystem services and human health. The goals of present study were document MP contamination in wild specimens Mytilus galloprovincialis sampled along Atlantic coast North region Portugal continental (NW Portuguese coast), estimate risk intake (HRI) through consumption local mussels as seafood. Mussels collected at four sampling sites NW (40 per site), whole soft body each mussel was analysed for content. HRI estimates based mean items wet weight tissue (MP/g) habits. A total 132 recovered from mussels. had diverse sizes (98 2690 μm) colours. most common shapes fibres (39%) pellets (36%). Five polymers identified MP: polyethylene (50%), polystyrene (15%), poly(ethylene vinyl acetate) (14%), polyamide (12%) polypropylene (9%). From 160 mussels, 55% MP. standard error ranged 0.206 ± 0.067 0.709 0.095 MP/g. For consumers study, decreasing order is MOL > CAB CAR EST. Compared other areas varied habits, relatively low.

Microplastics in marine mussels, biological effects and human risk of intake: A case study in a multi-stressor environment

Marine Pollution Bulletin, Journal Year: 2023, Volume and Issue: 197, P. 115704 - 115704

Published: Nov. 8, 2023

This study documented seasonal levels of microplastics (MPs) and biomarkers (condition index, neurotoxicity, energy, oxidative stress) in mussels (Mytilus galloprovincialis), water physico-chemical parameters the Douro estuary (NE Atlantic coast), estimated human risk MP intake (HRI) through mussels. Mussel stress was determined Integrated Biomarker Response (IBR). HRI from mussel concentrations consumer habits. MPs were mainly micro-fibres (72 %) with varied chemical composition. Seasonal means (±SEM) ranged 0.111 ± 0.044 (spring) to 0.312 0.092 MPs/g (summer). variations (IBR: 1.4 spring 9.7 summer) not related. MeO-BDEs, PBDEs, temperature, salinity other factors likely contributed variation. 2438 2650 MPs/year. Compared literature, contamination is low, as well their consumption.

Seasonal occurrence and distribution of microplastics in four different benthic suspension feeders from an Integrated Multi-Trophic Aquaculture (IMTA) facility: A bioremediation perspective

Marine Pollution Bulletin, Journal Year: 2024, Volume and Issue: 207, P. 116811 - 116811

Microplastics (MPs) are dangerous and ubiquitous in the environment. The urgency to contrast plastic pollution is prompting scientific community offer new proposals. Recently, bioremediation using filter feeders gaining consent as a nature-based solution. Herein four (Mytilus galloprovincialis Lamarck, 1819, Sabella spallanzanii Gmelin, 1791, Phallusia mammillata Cuvier, 1815, Paraleucilla magna Klautau, Monteiro & Borojevic, 2004), studied previous laboratory experiment MPs bioremediators, evaluated field conditions within 1-year.

Aquaculture in the crossroad of microplastic contamination

Marine Pollution Bulletin, Journal Year: 2025, Volume and Issue: 216, P. 117916 - 117916

Published: April 9, 2025

Plastic pollution threatens life and human health, with microplastics (MP) linked to seafood consumption. MPs enter aquaculture through the environment from gear. During production, plastic is used in nets sacks for growth process collecting processing so it becomes important expand knowledge about how much are present seafood. The aim was investigate presence of three bivalve's species; oysters (Crassostrea gigas), clams (Ruditapes decussatus), mussels (Mytilus galloprovincialis) produced offshore intertidal two different climate conditions. Water, bivalves sediments were collected each site abundance, size, colour, type composition polymers analysed. most common colour blue while black, fragments. Sixty per cent did not have their tissues. Bivalves less impacted by probably due hydrographic conditions distance coast. Most ingested related materials. Transformative solutions and/or procedures eliminate equipment needed, depuration might be a practical solution.

First Record of Microplastic Contamination in the Non-Native Dark False Mussel Mytilopsis leucophaeata (Bivalvia: Dreissenidae) in a Coastal Urban Lagoon

International Journal of Environmental Research and Public Health, Journal Year: 2023, Volume and Issue: 21(1), P. 44 - 44

Microplastic contamination is a global concern due to its conspicuous presence in aquatic ecosystems and toxic nature environmental human health. False mussels are among the most notable fresh- brackish water invaders. The invasive Mytilopsis leucophaeata Rodrigo de Freitas Lagoon-RFL (Rio Janeiro, Brazil) abundant macrofaunal invertebrate, widely established distributed throughout lagoon. This study aimed assess microplastic this filter feeder evaluate potential use as bioindicator. Agglomerates (~100 mussels) were manually collected using stainless-steel spatula ten sampling areas whole lagoon kept frozen. In laboratory, 60 individuals sorted by area for soft-tissue digestion. Each pool of 10 (n = 6 area) was wet-weighted then placed 150-mL decontaminated glass beaker with 50 mL 10% KOH. Samples heated (40 °C) 48 h, digested samples filtered glass-fiber membranes. Microplastics found all 60) from RFL; particles mostly lower than 100 µm mean concentration (±SD) 35.96 ± 47.64 MPs g wet-weight−1. distinguished seven shapes different occurrences (%): fiber (43.3%); fragment (34.3%); film (16.3%); sponge/foam (4.9%); pellet (0.57%), rope/filaments (0.17%); undefined (0.4%). Thirteen colors microplastics found, but transparent (54.94%), black (10.77%), white (9.36%) common. useful RFL might be preferentially used other invaded systems instead native often threatened bivalves. Our results confirm effective application bivalves an indicator coastal pollution.
