ClearEstimation of Polycyclic Aromatic Hydrocarbons in Groundwater from Campania Plain: Spatial Distribution, Source Attribution and Health Cancer Risk Evaluation
Researchers measured concentrations of polycyclic aromatic hydrocarbons, a group of potentially cancer-causing chemicals, in over 1,100 groundwater samples from the Campania Plain in southern Italy. They found the highest contamination levels in the Caserta Province area and used diagnostic ratios to identify both combustion and petroleum sources. The health risk assessment indicated that lifetime cancer risk from ingesting contaminated groundwater exceeded acceptable thresholds in some locations.
Levels of Polycyclic Aromatic Hydrocarbons in the Water and Sediment of Buffalo River Estuary, South Africa and Their Health Risk Assessment
Researchers assessed polycyclic aromatic hydrocarbon (PAH) contamination levels in the water and sediment of the Buffalo River Estuary in South Africa over six months. They found total PAH concentrations well above target safety values in both water and sediment samples, with levels higher during summer. Health risk assessments indicated elevated carcinogenic risk for both adults and children from dermal exposure, with the contamination primarily attributed to pyrolytic sources such as combustion processes.

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.
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.
First assessment of Polycyclic Aromatic Hydrocarbons contamination and associated human health risk in Mullet (Liza aurata) from Tunisia: case of Bizerte and Ghar El Melh Lagoons
Researchers measured 15 priority polycyclic aromatic hydrocarbons (PAHs) in mullet (Liza aurata) muscle tissue from two Tunisian lagoons (Bizerte and Ghar El Melh) in the first assessment of PAH contamination in biota from these ecosystems. PAH levels were comparable to or lower than global fish specimens, with chemical profiles indicating both petrogenic and pyrolytic anthropogenic sources.
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 in Soil and Vegetation of Niger Delta, Nigeria: Ecological Risk Assessment
Researchers assessed polycyclic aromatic hydrocarbon contamination in soils and vegetation across Nigeria's Niger Delta, finding elevated PAH levels in both matrices near oil exploration sites with ecological risk indices indicating significant environmental concern.
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.
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.
Environmental Risk Assessment of Polycyclic Aromatic Hydrocarbons in Farmland Soils near Highways: A Case Study of Guangzhou, China
Researchers assessed polycyclic aromatic hydrocarbon (PAH) contamination in roadside farmland soils near highways in Guangzhou, China across seasons, finding that PAH levels near high-traffic roads were significantly elevated above background. Vehicle emissions and tire wear were identified as the primary PAH sources, with carcinogenic risk scores exceeding safe thresholds at several sites.
Biodegradation and Impact of Polycyclic Aromatic Hydrocarbons in the Environment: A Review
This review examines polycyclic aromatic hydrocarbons (PAHs) — toxic compounds produced by incomplete combustion of fuels — covering their environmental sources, biodegradation pathways, and health risks including cancer, which they pose to humans, animals, and ecosystems.
Profile distribution of polycyclic aromatic hydrocarbons in coastal soils of the Lower Don and Taganrog Bay, Russia
This study analyzed the distribution of polycyclic aromatic hydrocarbons (PAHs) — persistent toxic pollutants — through soil profiles in the coastal zone of the Lower Don River and Taganrog Bay in Russia. PAHs co-occur with microplastics in polluted coastal environments and pose overlapping risks to soil and aquatic ecosystems.
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.

Microplastics and associated polycyclic aromatic hydrocarbons in surface water and sediment of the Bay of Bengal coastal area, India: sources, pathway and ecological risk
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.

Researchers compared six cancer risk assessment models for PM2.5-bound polycyclic aromatic hydrocarbons in Shanxi, China, and found that the USEPA inhalation risk model (Model I) was the most reliable, with inhalation identified as the dominant exposure pathway and lung cancer as the primary risk.
Seasonal variation, source identification, and health risk assessment of atmospheric polycyclic aromatic hydrocarbons (PAHs) in Ulsan, South Korea
Researchers monitored air pollution at a residential site in South Korea over three seasons and found that cancer-causing polycyclic aromatic hydrocarbons (PAHs) — byproducts of coal and oil burning — were highest in winter and partly blew in from China and North Korea, with some lesser-studied PAH types posing underappreciated health risks.
