ClearVerification of the existence of copper-based antifouling paint particles in the sea and their implications for marine microplastic degradation
Researchers collected marine debris near Nagasaki, Japan, and found copper-based antifouling paint particles alongside conventional microplastics at several sampling stations. These copper-based particles differ in chemical composition from typical plastic debris and may influence surrounding microplastic degradation patterns. The co-occurrence raises new questions about combined effects of paint particles and microplastics in marine environments.
Co-occurrence of microplastics and microparticles containing Cu and Zn and other heavy metals in sea-surface microlayer in Osaka Bay, Japan
Researchers analyzed tiny particles floating on the sea surface in Osaka Bay, Japan, and found microplastics containing heavy metals like copper and zinc from ship antifouling paints. Most of these metal-laden particles were made of acrylic resins commonly used in marine coatings, carrying copper concentrations up to 54,000 mg/kg. The study reveals that antifouling paint fragments are a significant and underrecognized source of toxic metal-containing microplastics in coastal waters.

These particles contain both plastic binder material and toxic metals like copper and zinc used as biocides. This study reveals an often-overlooked source of microplastic pollution in the ocean, where the released particles carry both plastic and heavy metal contamination into marine ecosystems.

A mass-based Py-GC/MS survey of microplastics in the German Bight (North Sea) found highly variable concentrations (2–1396 µg/m³) influenced by oceanographic conditions, with coastal samples showing packaging waste signatures and central areas revealing an unexpected signal consistent with marine antifouling paint.
Seawater copper content controls biofilm bioaccumulation and microbial community on microplastics
Researchers found that seawater copper concentration controls both the microbial community composition of biofilms on microplastics and the amount of copper bioaccumulated in those biofilms, demonstrating that metal pollution levels in seawater influence the ecological and chemical behavior of the 'plastisphere'.
The potential release of microplastics from paint fragments: Characterizing sources, occurrence and ecological impacts
This review examines paint fragments as a significant but often overlooked source of microplastic pollution, coming from deteriorating building coatings, road markings, and ship hulls. Beyond the plastic particles themselves, paint fragments can release toxic biocides and heavy metals that harm aquatic and terrestrial organisms. The findings highlight paint as a source of microplastics that people may encounter through water, air, and food, but which receives far less attention than packaging or textile sources.
Paint: a ubiquitous yet disregarded piece of the microplastics puzzle
This review found that microplastics from paint and coatings are a largely overlooked but major source of plastic pollution, with concentrations reaching up to 290,000 particles per kilogram of sediment near painted surfaces. Paint microplastics come from buildings, cars, boats, and industrial infrastructure. Of the toxic effects tested, 66% showed significant harm to organisms, particularly from antifouling paints, yet very few studies have examined this pollution source.
Paint particles in the marine environment: An overlooked component of microplastics
Researchers highlight that paint particles, which consist of polymers combined with additives, are frequently overlooked or misclassified in studies of marine microplastic pollution. They found that paint fragments from ships, buildings, and infrastructure represent a significant but underreported source of microplastic contamination in ocean environments. The study calls for paint particles to be consistently included in marine debris monitoring to provide a more accurate picture of plastic pollution.
Environmental micropaint: a primary review of sampling techniques and analytical approaches
This review synthesizes findings from 74 studies on micropaint particles, a class of environmental contaminants distinct from conventional microplastics that originate from degradation of coated surfaces and antifouling paints, and are enriched with heavy metals and biocidal additives. The authors identify critical gaps in standardized sampling protocols, analytical methods for differentiating micropaints from microplastics, and knowledge of their ecotoxicological effects particularly in coastal zones.
