Current status and challenges of remediating petroleum‐derived PAHs in soils: Nigeria as a case study for developing countries

Abstract

Polycyclic aromatic hydrocarbons (PAHs) are among the world's most significant environmental organic contaminants because of their carcinogenic properties.PAHs are widely distributed globally as a result of releases from numerous natural and anthropogenic activities. Consequently, several PAH monitoring studies have been conducted and remediation approaches explored. This article aims to provide the current status of PAH distribution in Nigeria's oil and gas industrial region in relation to the technologies adopted for PAH remediation.Ideally, the findings will provide insight into the challenges in managing organic contaminants derived from petroleum exploration activities in developing countries with Nigeria as a case study.

Biofilm mediated degradation of commercially available LDPE films by bacterial strains isolated from partially degraded plastic

“…Moreover, these other physical processes, especially the chemical ones, produce intermediate chemicals that may be toxic (Manchola & Duss, 2014). Biological remediation (bioremediation), also referred to as microbial degradation, involves microorganisms degrading polymeric substances (Offiong, Etuk, & Essien, 2019). The plastic biodegradation process is dependent on the plastic colonizing ability of bacteria and their potential ability of degrading polyethylene (PE).…”

Metagenomic signature and total petroleum hydrocarbons distribution in a crude oil contaminated ultisol remediated with biochar–humus sediment slurry

“…Crude oil spills and subsequent contamination of surrounding environments pose serious long‐term threats to both environmental, social, and economic wellbeing of the affected societies (Loureiro et al, 2009; McCrea‐Strub et al, 2011; Offiong et al, 2019; Soares et al, 2020; Wang et al, 2020). Over the years, researchers have developed several strategies to prevent and manage oil spills.…”

Trace Metal Levels and Nutrient Characteristics of Crude Oil-Contaminated Soil Amended with Biochar–Humus Sediment Slurry

“…Soil pollution by crude oil spills still constitutes a major environmental problem in many countries where oil exploration is the mainstay of the economy [1]. The introduction of potentially toxic trace metals and organic contaminants into the environment is considered a threat to human and environmental health [2][3][4][5].…”
