From Biological Activity to Flow Assurance: An Evidence-Qualification Framework for Biocatalytic and Bio-Derived Wax Control in Waxy Crude Oils

Wax accumulation and gel formation remain critical flow assurance obstacles in the extraction and conveyance of waxy crude oils, whereby precipitation, crystal development, aggregation, ageing, rheological behavior, and wall deposition are interrelated yet distinct processes. Tra...

Black carbon in urban atmospheres: source apportionment, mixing states, and implications for climate and respiratory health

Black carbon (BC) is a major urban pollutant affecting climate and health. This review examines studies published between 2018 and 2026 on BC sources, mixing state, and impacts. Traffic emissions dominate developed cities, while biomass and residential combustion are major source...

Polycyclic aromatic hydrocarbon levels and health risk assessment of sediment and shellfish from coastal communities in the Niger Delta, Nigeria

This study investigated the occurrence, distribution, and potential health risks of polycyclic aromatic hydrocarbons (PAHs) in sediment and shellfish collected from the Santa Barbara River (Nembe) and Sangana River (Brass), two coastal communities in the Niger Delta, Nigeria. Six...

CrayStack ensemble machine learning for predicting engine performance and emissions of multiple feedstock biodiesel blends with CaO-Al2O3 nanoparticles

Abstract The global transition toward sustainable energy has positioned multi-oil feedstocks (Garcinia gummi-gutta and Garcinia indica) to increase feedstock availability, which is vital to biodiesel production, thereby reducing fossil fuel dependencies and limiting harmful emiss...

Impact of particulate matter and heavy metals emissions from automotive painting booths on ambient air quality

This study investigated the particulate and heavy metal emissions arising from automotive paint applications. A total of 22 sampling locations, represented as AQ1 - AQ22 for this study. Concentrations of particulate matters were determined using Aerocet 831 particle counter while...

Integrated Assessment of Surface-Water Pollution, Human Health Risks, Oil-Spill Preparedness, and Community Resilience in Petroleum-Producing Communities of Delta State, Nigeria

Pollution of surface water in a petroleum-producing community has overlapping environmental, health, livelihood, and resilience challenges. Water-quality assessment, human-health risk modelling and socioeconomic analysis was incorporated into this study for 9 communities in Delta...
