ClearA 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.

This study examined the presence of phthalate esters (PAEs) and polycyclic aromatic hydrocarbons (PAHs) in various everyday plastic products and assessed their potential to leach into the environment. Plastic additives like phthalates are endocrine disruptors that can leach from microplastics into surrounding media, posing risks to organisms that ingest plastic particles or live in contaminated water.
Microplastics as a Modifier of Polycyclic Aromatic Hydrocarbon (PAH) Toxicity: A Review on Context-Dependent Effects Across Organisms
This review of 45 studies found that tiny plastic particles (microplastics) don't just add to the harm caused by toxic chemicals called PAHs—they can either make these chemicals more or less dangerous depending on the situation. The plastic pieces can either help chemicals get absorbed more easily into living things or trap the chemicals and reduce exposure. Since microplastics and these toxic chemicals are found together in our environment, this research shows we need better ways to understand how pollution mixtures affect human and environmental health.
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.
