Temporal Dynamics, Ecotoxicological Hazard Characterization, and Human Cancer Risk Assessment of Polycyclic Aromatic Hydrocarbons in Crude Oil-Contaminated Tropical Soils under Biochar Amendment and Bacterial Bioremediation

Remediation of Petroleum - Sludge Contaminated Soil Enhanced with Organic Wastes (Sterilized Cow Dung and Plantain Peel Biochar)

Petroleum sludge contamination remains a pressing challenge in oil-producing regions, posing risks to soil health, ecosystem and public safety due to the high concentrations of hydrocarbons such as Total Petroleum Hydrocarbons (TPH) and Polycyclic Aromatic Hydrocarbons (PAHs). This study investigated the remediation po...

Assessing coastal environmental impacts of polycyclic aromatic hydrocarbons in Alang-Sosiya Shipbreaking Yard sediments: Source distribution and human–ecological risk assessment

Kinetics and Microbial Population Dynamics of Leaf-Biostimulated Crude Oil Bioremediation in Contrasting Soils

Crude oil contamination remains a persistent environmental burden in petroleum-producing regions, and low-cost, locally sourced plant-leaf biostimulants offer a promising route to accelerate hydrocarbon-degrading microbial activity in impacted soils. This study evaluated the bacterial and fungal population dynamics a...

Characterization and Soil Remediation Performance of a Natural Polycyclic Aromatic Hydrocarbon-Degrading Bacterial Consortium (PD1).

Polycyclic aromatic hydrocarbons (PAHs) are persistent and toxic soil contaminants that pose significant risks to environmental and human health. In this study, a natural PAHs-degrading microbial consortium (PD1) was enriched from coal gangue backfill soil using phenanthrene as the sole carbon source. PD1 features Acid...

Effects of Garden Waste Biochar Amendment on TPH Removal and Bacterial Community Restructuring in Petroleum-Contaminated Soil

Petroleum hydrocarbon contamination poses a persistent threat to soil quality and ecosystem functioning, while conventional remediation approaches are often costly and difficult to sustain over the long term. This study evaluated garden waste biochar as a sustainable amendment for the remediation of petroleum-contamina...

Integrating Empirical Ecotoxicology and Predictive Modelling to Assess Ecological and Human Health Risks from Heavy Metals in Malaysia's Chini Lake UNESCO Biosphere Reserve.

Chini Lake, Malaysia's first UNESCO-designated biosphere reserve, exemplifies the growing challenge of safeguarding freshwater ecosystems exposed to legacy mining activities and ongoing land-use disturbance. Mining and other anthropogenic activities have contributed to persistent heavy metal contamination in freshwater...
