ClearDistribution, Source Appropriation, and Human Health Risk Assessment of Polycyclic Aromatic Hydrocarbons due to Consumption of Callinectes amnicola from Woji Creek inSambreiro River
Researchers measured PAH contamination in crabs from a Nigerian river and assessed the cancer risk from eating them, finding elevated concentrations of harmful aromatic hydrocarbons. Children and young adults faced the highest calculated cancer risk from crab consumption at these levels.
Contamination Levels and Accumulation Profiles of Polycyclic Aromatic Hydrocarbons (PAHs) in Surface Sediments from South Central Coast of Vietnam
Polycyclic aromatic hydrocarbons were quantified in surface sediments from the South Central Coast of Vietnam, characterizing sources, spatial distribution, and potential ecological risk from these hydrophobic persistent organic pollutants.
Assessment of Heavy Metal Exposure in Soils of Ihwrekreka Communities, Delta State, Nigeria
Soil samples from crude oil-polluted communities in the Ihwrekreka area of Nigeria's Niger Delta were analyzed for heavy metal concentrations using inductively coupled plasma optical emission spectrometry. The study assessed potential health risks to residents from exposure to chromium, nickel, lead, cadmium, and other metals elevated by decades of petroleum contamination.
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.
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.
Radioactivity distributions and biohazard assessment of coastal marine environments of niger-delta, Nigeria
Researchers assessed radioactivity and pollution levels in the coastal marine environment of Nigeria's Niger Delta. They found that radionuclide concentrations in sediments and water exceeded recommended safety limits, with certain fish species accumulating higher levels of radioactive elements. The study recommends continuous monitoring of these polluted coastal waters to protect both ecological and human health.
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.
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.
Presence and Abundance of Microplastics in Benthic Organisms from Some Niger Delta, Nigeria Coastal Rivers
Researchers investigated the presence and abundance of microplastics in benthic organisms collected from coastal rivers in the Niger Delta region of Nigeria, documenting contamination levels in organisms from these ecologically significant waterways.
Environmental and Toxicological Perspectives of Soil Microplastics in Northern Nigeria
This study examined microplastic occurrence and toxicological implications in soils of Northern Nigeria, identifying agricultural plastics, industrial waste, and urban runoff as key sources. The research addressed a gap in African soil MP research and highlighted ecosystem and food safety risks in the region.
Effects of Polycyclic Aromatic Hydrocarbons on the Composition of the Soil Bacterial Communities in the Tidal Flat Wetlands of the Yellow River Delta of China
Researchers found that polycyclic aromatic hydrocarbons (PAHs) significantly altered soil bacterial communities in tidal flat wetlands of China's Yellow River Delta. The study suggests PAH contamination reduces bacterial diversity while shifting the relative abundance of key bacterial phyla, with soil properties like nitrogen, carbon, and phosphorus playing important roles in shaping microbial community responses.
Hazards Associated with Plastic Wastes in the Communities of Niger Delta, Nigeria
A field study in Niger Delta communities measured plastic waste contamination in water, fish, sediment, and human blood samples, linking physicochemical anomalies to plastic pollution from local improper waste disposal.
Health and Environmental Hazard of Plastic Waste in The Communities of Niger Delta
This study investigated plastic waste health impacts in Niger Delta communities by analyzing water, fish, sediment, and human blood samples for physico-chemical parameters and contaminants. Microplastics and associated chemical pollutants were detected, highlighting risks to residents in areas with poor waste management infrastructure.
Evaluation of the Effects of Heavy Metals on Water from Illegal Crude Oil Refineries: a Case Study of Three Selected Communities in the Niger Delta Region, Nigeria
This paper is not about microplastics; it measures heavy metal contamination (and associated health risk indices) in surface water near illegal crude oil refineries in three communities of Nigeria's Niger Delta region.
Microplastic Contamination and Its Impact on Soil Properties Across Different Land Uses in Cross River State, Nigeria
A survey of soils across four land-use types in southeastern Nigeria found microplastic concentrations up to 12 times higher in commercial areas than in forests, with contamination linked to changes in soil structure, nutrient availability, and water infiltration. This is the first large-scale assessment of microplastic distribution in Nigerian tropical soils, filling a major data gap for sub-Saharan Africa. The findings suggest that heavily contaminated commercial soils may have degraded agricultural and ecological functionality, with consequences for food security in the region.
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.
