                  abstract = {The Niger Delta region of Nigeria faces severe environmental degradation from petroleum refining activities and agro-industrial processing. This review synthesizes evidence from peer-reviewed studies on the characterization, toxicological risks, and remediation strategies for these dual pollution streams. Petroleum refining emissions, including volatile organic compounds and particulate matter, demonstrate total petroleum hydrocarbon concentrations reaching 42,200 µg/L in groundwater, far exceeding international safety limits. Artisanal refining contributes significantly to air pollution, with hydrocarbon emissions constituting 52-55% of total pollutants and carbon monoxide comprising 38-41% across processing units. Agro-industrial effluents, particularly cassava mill wastewater and palm oil mill effluent, introduce cyanide, heavy metals, and high organic loads into terrestrial and aquatic ecosystems. Health impacts include respiratory disorders affecting 35-45% of exposed communities, reproductive risks, and elevated cancer incidence with total mean cancer risk exceeding USEPA threshold of 1×10⁻⁴ in all studied samples. Technological advancements in emission characterization include emission factor determination for artisanal refineries and geospatial analysis of pollution dispersion. Sustainable remediation strategies encompass enhanced natural attenuation demonstrating successful soil restoration, biochar-based treatments achieving 87.76% total petroleum hydrocarbon removal, and hybrid bio-adsorbents from agricultural waste showing adsorption capacity of 21.4 mg/kg. Policy recommendations emphasize integrated pollution load control, strengthened regulatory enforcement, and community-based monitoring frameworks to safeguard environmental and public health in the region.},
