Microplastics in a mosaic of Marine Protected Areas from southeastern Brazil: An assessment based on filter-feeding bivalves
Researchers used filter-feeding bivalves as biological monitors to assess microplastic contamination across 28 marine protected areas along a heavily populated stretch of coastline in southeastern Brazil. They found microplastics in bivalves from all sites surveyed, demonstrating that protected status alone does not shield marine areas from plastic pollution. The study highlights how diffuse, transboundary plastic contamination reaches even designated conservation zones.

Chemical composition of microplastic in sediments and protected detritivores from different marine habitats (Salina Island)
This study characterized microplastics in sediments and sea cucumbers across different rocky-bottom habitats at Salina Island, Italy, finding that chemical composition varied by habitat type. Correlations were also found between microplastic composition and the diversity and coverage of benthic species at each site.
Identification and Quantification of Phthalate Pollution in Holothuria atra, a Sea Cucumber from the Persian Gulf (Iran)
Phthalate plasticizers were detected in sea cucumbers (Holothuria atra) collected from the Persian Gulf in Iran, indicating that these marine invertebrates accumulate plastic-derived chemicals from their environment. Sea cucumbers are consumed as food in many Asian countries, raising food safety concerns.
Detection of microplastics and phthalic acid esters in sea urchins from Sardinia (Western Mediterranean Sea)
Wild sea urchins from Sardinia in the western Mediterranean were found to contain microplastics in 9 of 22 specimens analyzed, with up to 4 particles per individual in the digestive tract. Phthalic acid esters were also detected in the gonads of 20 specimens, with an average concentration of 32 nanograms per gram.
Plastic litter transfer from sediments towards marine trophic webs: A case study on holothurians
Sea cucumbers collected from the seafloor around a Sicilian island were found to contain microplastics in their bodies, having ingested them while feeding on sediment. Since sea cucumbers are consumed as food in many cultures, this represents a direct pathway for microplastic exposure in humans.
High levels of microplastics and microrubber pollution in a remote, protected Mediterranean Cladocora caespitosa coral bed
Researchers discovered high levels of microplastic and microrubber pollution in sediments surrounding a protected Cladocora caespitosa coral bed in the northwestern Mediterranean Sea. The study suggests that even protected marine areas with coral communities are not immune to plastic contamination, raising concerns about the ecological impact on these already threatened reef ecosystems.
A global snapshot of microplastic contamination in sediments and biota of marine protected areas
A global snapshot of microplastic contamination in sediments and biota across marine protected areas (MPAs) found that microplastics are ubiquitous even in these conservation zones, undermining their protective function. The review synthesizes occurrence data and calls for microplastic monitoring to be integrated into MPA management plans.
Evaluation of microplastics isolated from sea cucumber Acaudina molpadioides in Pulau Langkawi, Malaysia
Researchers examined sea cucumbers from Langkawi, Malaysia and found over 1,600 microplastic particles in their digestive tracts, with fibers making up more than 99% of the contamination. The most common polymer types identified were polyethylene and polymethyl methacrylate, with the majority of particles falling in the smallest size ranges. The findings raise concerns about potential human exposure to microplastics through seafood consumption.
Evaluation of Microplastics Ingested by Sea Cucumber Holothuria Scabra from Pulau Jambongan, Sabah
Researchers found 7,403 microplastic particles in the digestive tracts of 30 sea cucumbers (Holothuria scabra) collected from a Malaysian island, with 99% being fibers and the dominant polymer being polymethyl methacrylate (PMMA). The high contamination level indicates significant marine pollution in the region and shows that bottom-dwelling sea cucumbers — which process large volumes of sediment — are especially exposed to microplastic accumulation. This is relevant to seafood safety since sea cucumbers are commercially harvested for human consumption.
An Analysis of Microplastics Ingested by the Mediterranean Detritivore Holothuria tubulosa (Echinodermata: Holothuroidea) Sheds Light on Patterns of Contaminant Distribution in Different Marine Areas
Researchers analyzed microplastic ingestion by the Mediterranean sea cucumber Holothuria tubulosa across different marine areas, revealing spatial patterns of contamination that reflect local pollution levels and the species' potential as a bioindicator.
Phthalates and organophosphate esters in surface water, sediments and zooplankton of the NW Mediterranean Sea: Exploring links with microplastic abundance and accumulation in the marine food web
Phthalate esters and organophosphate esters were measured alongside microplastics in surface seawater, sediment, and zooplankton from Marseille Bay in the northwestern Mediterranean Sea. Co-occurrence of microplastics and plastic additive chemicals in multiple environmental compartments including zooplankton confirmed trophic transfer of both particle and chemical contaminants.
Phthalate diester occurrence in marine feed and food (Mediterranean Sea)
Researchers detected phthalate diesters in Mediterranean Sea zooplankton, fish, and bivalves, with DEHP found in all zooplankton samples and 30% of fish, demonstrating how microplastics transport these endocrine-disrupting chemicals through marine food webs.
Microplastics occurrence in sea cucumbers and impacts on sea cucumbers & human health: A systematic review
This systematic review found that microplastics are ubiquitous in sea cucumber ecosystems, with high concentrations in coastal sediments where these deposit feeders live. Some studies report that microplastic ingestion reduces sea cucumber feeding efficiency, alters behavior, and causes tissue damage, raising concerns for both ecosystem health and human consumers of this seafood.
Microplastic Contamination in Protected Areas of the Gulf of Venice
Plastic pollution was found in nearly all seven protected marine areas studied in the Gulf of Venice, with microplastics dominating. The findings suggest that official conservation status does not shield coastal sediments from plastic contamination.
Human health risk assessment for consumption of microplastics and plasticizing substances through marine species
Researchers analyzed three seafood species from Ecuador and found microplastics along with plastic-derived chemicals including bisphenol-A and phthalates in all samples. The microplastics ranged in size from less than 1 micrometer to over 100 micrometers and included fragments, fibers, and films. The study assessed human health risks from consuming these contaminated species and found that estimated daily intake of certain plasticizers approached levels of concern.

Researchers used Mediterranean fish and invertebrates as bioindicators of plastic pollution, correlating microplastic ingestion levels with phthalate ester concentrations in their tissues to validate the use of combined biological monitoring for tracking spatial and temporal trends in marine plastic contamination.
Bioaccessibility of plastic-related compounds from polymeric particles in marine settings: Are microplastics the principal vector of phthalate ester congeners and bisphenol A towards marine vertebrates?
Researchers studied whether microplastics are a major pathway for delivering harmful plastic chemicals like phthalates and bisphenol A to marine animals during digestion. They found that while microplastics do release these compounds under simulated gut conditions, the amounts were relatively low compared to other environmental sources. The study suggests that microplastics may not be the primary route of chemical exposure for marine vertebrates, though they still contribute to the overall burden.
Microplastics ingestion by deep-sea decapod crustaceans from the Western Mediterranean
