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.
Sorption, Extraction, and Characterization of Polycyclic Aromatic Hydrocarbons in Environmentally Weathered Microplastics, Particulate Organic Matter, Sediment, and Fish Species in the Lavaca-Matagorda Bay System
Researchers studied how microplastics carry cancer-causing chemicals called polycyclic aromatic hydrocarbons (PAHs) in the Lavaca-Matagorda Bay system in Texas. They found PAHs attached to microplastics, sediment, and in the digestive systems of three commercially important fish species. This shows that microplastics can act as vehicles for toxic chemicals in coastal waters, potentially affecting the safety of fish that people eat.
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.
Health Risk Assessment of Packaging Materials and Chemical Contaminants in Grilled Foods in Ilorin, Kwara State Nigeria
This study measured concentrations of polycyclic aromatic hydrocarbons, nitrosamines, and acrylamide in grilled beef, chicken, and fish sold in Ilorin, Nigeria, and assessed associated health risks from packaging materials. PAH levels in some samples exceeded safe limits, and certain packaging materials contributed additional chemical contamination, posing cancer risk concerns.
Multibiomarker Responses to Polycyclic Aromatic Hydrocarbons and Microplastics in Thumbprint Emperor Lethrinus Harak from a South Pacific Locally Managed Marine Area
This study measured microplastics and cancer-linked PAH chemicals in emperor fish from Fiji's coastal waters, finding PAHs present in all samples tested. The results suggest that consuming seafood from these waters carries some chemical exposure risk.
A Review of Chemical Contaminants in Marine and Fresh Water Fish in Nigeria
This review compiled data on chemical contaminants including PAHs, persistent organic pollutants, heavy metals, and microplastics in freshwater and marine fish from Nigeria, finding that most contaminant levels fall below international food safety thresholds but identifying lead, iron, and smoked fish PAHs as potential health concerns in specific locations.
Evaluation of Polyciclic Aromatic Hydrocarbons in Water and Microplastics
Researchers measured five cancer-linked PAH compounds in water samples and found that microplastics can bind these chemicals, potentially concentrating them. This suggests microplastics may act as carriers of carcinogenic compounds in drinking water and aquatic environments.
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.
PM2.5-bound polycyclic aromatic hydrocarbons (PAHs): quantification and source prediction studies in the ambient air of automobile workshop using the molecular diagnostic ratio
Researchers measured cancer-causing polycyclic aromatic hydrocarbons (PAHs) bound to fine airborne particles near automobile workshops in Nigeria, finding concentrations well above safe levels in both dry and rainy seasons. Gasoline and diesel combustion were the main sources of these toxic compounds. While not directly about microplastics, PAHs are among the harmful chemicals that can stick to microplastic surfaces, and this study shows how airborne pollution creates chemical contaminants that microplastics can transport into water, soil, and the body.
Detection of Microplastic Pollutants and the Wellbeing of Clarias gariepinus (African Catfish) in Jama’are River, Bauchi State, Nigeria
Researchers detected multiple types of microplastics — including polyethylene, polypropylene, and PVC — in water and fish from a Nigerian river, and found that African catfish living there showed signs of tissue damage and altered blood markers, indicating that microplastic contamination is harming freshwater fish health in the region.
Occurrence of Polycyclic aromatic hydrocarbons (PAHs) in mullet (Liza aurata) from Bizerte and Ghar El Melh Lagoons (Tunisia) and associated human health risk assessment
Researchers measured concentrations of 15 priority polycyclic aromatic hydrocarbons (PAHs) in golden grey mullet (Liza aurata) muscle tissue from the Bizerte and Ghar El Melh Lagoons in Tunisia, finding PAH levels comparable to or lower than those reported globally for fish. Human health risk assessment indicated that PAH intake from mullet consumption does not pose a significant cancer risk to local consumers, though the detected compound profiles revealed both petrogenic and pyrolytic contamination sources.

Researchers surveyed microplastic contamination in surface water and sediment along two Bay of Bengal coastal beaches in India and found microplastics present at both sites. They also detected polycyclic aromatic hydrocarbons, a group of harmful chemicals, adsorbed onto the microplastic surfaces at concentrations that varied by particle shape. The study highlights that microplastics in coastal waters act as carriers for toxic organic pollutants, potentially increasing ecological risks in the marine environment.
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.
