Correlation between Polycyclic Aromatic Hydrocarbons in Wharf Roach (Ligia spp.) and Environmental Components of the Intertidal and Supralittoral Zone along the Japanese Coast
Researchers measured polycyclic aromatic hydrocarbon (PAH) concentrations in wharf roaches, mussels, and environmental media at 12 coastal sites in Japan, finding that wharf roaches accumulate PAHs primarily from food (drifting seaweed) and sediment, suggesting their utility as bioindicators of coastal PAH pollution.

Polycyclic aromatic hydrocarbons were quantified in surface sediments from the South Central Coast of Vietnam, characterizing sources, spatial distribution, and potential ecological risk from these hydrophobic persistent organic pollutants.
Association between PAH and plastic fragments on Brazilian coast beaches: a baseline assessment
Researchers conducted a baseline assessment of the association between polycyclic aromatic hydrocarbons (PAHs) and plastic fragments collected from beaches along the Brazilian coast, characterising how microplastics act as adsorption surfaces for these organic pollutants. The study found co-occurrence of PAHs and plastic fragments at sampled sites, establishing contamination baselines and informing understanding of the plastic-pollutant vector pathway.
Sorption of benzo(a)pyrene and of a complex mixture of petrogenic polycyclic aromatic hydrocarbons onto polystyrene microplastics
Researchers investigated the sorption of benzo(a)pyrene and a complex mixture of petrogenic polycyclic aromatic hydrocarbons onto polystyrene microplastics in aquatic systems, quantifying how the hydrophobic nature and large surface area of microplastics facilitate PAH accumulation and potential vector transport.
Colour spectrum and resin-type determine the concentration and composition of Polycyclic Aromatic Hydrocarbons (PAHs) in plastic pellets
Plastic pellets collected from beaches were found to contain polycyclic aromatic hydrocarbons (PAHs, which are carcinogenic compounds), with darker-colored pellets generally having higher concentrations. This shows that plastic pellets can accumulate toxic chemicals from the environment and carry them to beaches where they may be ingested by wildlife.
Sources, Occurrences, and Risks of Polycyclic Aromatic Hydro-Carbons (PAHs) in Bangladesh: A Review of Current Status
This review examines levels of polycyclic aromatic hydrocarbons (PAHs), toxic chemicals from burning fossil fuels, across water, soil, air, and seafood in Bangladesh, finding concentrations higher than in most other countries. Health assessments revealed both cancer and non-cancer risks to residents from eating contaminated seafood. While focused on PAHs rather than microplastics directly, the findings are relevant because microplastics can absorb and concentrate these same cancer-causing chemicals, potentially worsening human exposure.
Revisiting the analytical determination of PAHs in environmental samples: An update on recent advances
This review critically examines recent advances in sample preparation and instrumental methods for determining polycyclic aromatic hydrocarbons in environmental matrices including air, water, soil, and biota.
Toxicities of Polycyclic Aromatic Hydrocarbons for Aquatic Animals
This review examines the toxicity of polycyclic aromatic hydrocarbons (PAHs) in aquatic animals, including their effects on hormones, tissue damage, and cancer risk. Researchers highlight the growing concern about microplastics acting as carriers for these harmful chemicals in water environments. The study emphasizes the need to address PAH pollution in aquatic ecosystems, particularly as microplastics may increase organisms' exposure to these toxic compounds.
Assessment of cancer risk of microplastics enriched with polycyclic aromatic hydrocarbons
Researchers assessed the cancer risk of microplastics originating from e-waste that had adsorbed carcinogenic polycyclic aromatic hydrocarbons (PAHs). The study found that microplastics effectively captured PAHs through adsorption and estimated the probable cancer risk from human ingestion of PAH-enriched microplastics, suggesting this exposure pathway warrants further health risk evaluation.
Polycyclic aromatic hydrocarbons affiliated with microplastics in surface waters of Bohai and Huanghai Seas, China
Microplastics collected from surface waters of the Bohai and Huanghai Seas in China were found to carry polycyclic aromatic hydrocarbons (PAHs) at concentrations exceeding those in surrounding water, acting as concentrators of these carcinogenic compounds. The study documents that microplastics in heavily industrialized Chinese coastal seas accumulate PAHs that can be transferred to organisms that ingest them.
Accumulation of HOCs via Precontaminated Microplastics by Earthworm Eisenia fetida in Soil
Researchers incubated earthworms in soil amended with five types of microplastics precontaminated with polychlorinated biphenyls and polycyclic aromatic hydrocarbons to assess whether pre-contaminated MPs enhance HOC transfer to terrestrial organisms. Results showed that precontaminated microplastics significantly increased earthworm accumulation of PCBs and PAHs compared to controls, demonstrating that the contamination history of MPs entering soil is a critical but overlooked factor in risk assessment.
A review of human and animals exposure to polycyclic aromatic hydrocarbons: Health risk and adverse effects, photo-induced toxicity and regulating effect of microplastics
This review examines the health risks of polycyclic aromatic hydrocarbons (PAHs), toxic chemicals from burning fossil fuels, and how microplastics can change their behavior in the environment. Microplastics absorb PAHs on their surface, potentially carrying these cancer-causing chemicals into organisms that ingest the contaminated particles. The combined toxicity of PAHs attached to microplastics may be greater than either pollutant alone, increasing risks to both wildlife and human health.

Microplastic and POP contamination in rural waste-dumping sites, India
Researchers collected soil and water samples from unregulated waste-dumping sites in rural Tamil Nadu, India, finding microplastics in all samples, with polypropylene and polyethylene as the dominant polymers, raising concerns about contamination of drinking water and agricultural land.
Assessment of Health Risks from Agricultural Soils Contaminated with Polycyclic Aromatic Hydrocarbons (PAHs) Across Different Land-Use Categories of Bangladesh
Researchers assessed levels of polycyclic aromatic hydrocarbons (PAHs), a group of harmful chemical pollutants, in agricultural soils across Bangladesh. Industrial areas had the highest contamination levels, followed by coastal and market areas, with concentrations declining at greater soil depths. The study found that while current exposure levels pose low cancer risk, continued monitoring is needed since these persistent chemicals accumulate in soil and can enter the food chain.
Evaluation of the adsorption efficiency of carcinogenic PAHs on microplastic (polyester) fibers—preliminary results
Researchers found that polyester microfibers — the tiny plastic threads shed from clothing during washing — can absorb large amounts of cancer-linked polycyclic aromatic hydrocarbons (PAHs), accumulating up to 1,255 micrograms per gram of fiber, which means microplastics in sewage sludge may be concentrating toxic chemicals before they reach the environment.

Meta-Analysis of a New Georeferenced Database on Polycyclic Aromatic Hydrocarbons in Western and Central Mediterranean Seafood
This meta-analysis built a georeferenced database of polycyclic aromatic hydrocarbon (PAH) contamination in Western and Central Mediterranean seafood, finding that PAH levels vary significantly by species biology, habitat, and proximity to pollution sources. Filter-feeding organisms and those in coastal areas showed higher contamination levels. PAHs are among the hydrophobic organic pollutants that readily adsorb onto microplastic surfaces, making microplastics potential vectors for concentrating and transporting these carcinogens through marine food webs.
