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.

POLYCYCLIC AROMATIC HYDROCARBONS (PAHs) IN INDRAMAYU COASTAL, WEST JAVA: DISTRIBUTION, SOURCE, AND ECOLOGICAL RISK ASSESSMENT

Researchers assessed the distribution, sources, and ecological risk of polycyclic aromatic hydrocarbons in seawater and sediment samples from Indramayu Coast in West Java, Indonesia. Low molecular weight PAHs dominated, and source analysis pointed to both petrogenic and pyrogenic origins.

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.

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.

Health risk-benefit assessment of the commercial red mangrove crab: Implications for a cultural delicacy

Researchers conducted a risk-benefit assessment of red mangrove crabs from Ecuador's Guayas estuary, finding that inorganic arsenic was the primary contaminant of concern and that safe consumption is possible in limited portions, underscoring how environmental pollution quality directly constrains the safety of culturally important seafood.

Assessment of Heavy Metal Contamination in Shrimp and Water from the Great Kwa River: Implications for Human Health and Aquatic Ecosystems

Researchers measured heavy metal concentrations in shrimp and water samples from Nigeria's Great Kwa River. The study found elevated levels of several toxic metals linked to oil exploration and industrial activities, with some metals in shrimp tissue exceeding safe consumption limits, raising concerns about health risks for local communities who rely on river shellfish as a food source.

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.

Estimation 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.

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.
