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.
Environmental Impact Of 2A 2B Carcinogenic Polycyclic Aromatic Hydrocarbons (PAHs) in Industrial Soil: Status, Profile, Concentration and Assessment to Humans Health Risk
Researchers collected surface soil samples from five industrial zones in Riyadh and quantified IARC Group 2A and 2B carcinogenic polycyclic aromatic hydrocarbons, assessing cancer risk to adults and children via ingestion, dermal contact, and dust inhalation pathways, finding that children faced elevated risk due to soil ingestion behavior.
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.
