“…Oxidized PAHs exhibit potential genotoxicity, causing damage to cells and DNA(Clerge et al, 2023b), and PAH contamination in sh products could potentially pose toxicity to human health through the food chain (de Pinho et al, 2023). In addition, during the bioremediation process, PAHs may generate toxic degradation products(Bonatti et al, 2023;Gou et al, 2023;Jimenez-Volkerink et al, 2023). However, current research is predominantly focused on the evaluation or degradation of LMW-PAHs, such as phenanthrene, anthracene, and naphthalene, with fewer detailed studies on the toxicity and degradation products of HMW-PAHs.…”

High-molecular-weight polycyclic aromatic hydrocarbons (HMW-PAHs) are an important group of persistent organic pollutants. Bioremediation has emerged as a cost-effective and environmentally friendly technique to remediate HMW-PAH contamination. In this study, we conducted a comprehensive bibliometric analysis using VOSviewer software on a dataset comprising 3009 relevant publications retrieved from the Web of Science database. Our analysis specifically focused on exploring the research landscape of bioremediation strategies for common HMW-PAHs, denoted as BC-HMW-PAHs. By employing cocitation analysis, co-occurrence analysis, and clustering analysis, we unveiled the knowledge foundation of BC-HMW-PAH bioremediation research, with notable contributions from renowned academic journals such as Applied and Environmental Microbiology, Chemosphere, and Environmental Science & Technology. The research in this field is interdisciplinary and includes the fields of environmental science, biotechnology, applied microbiology, microbiology, engineering, and toxicology. The key research themes identified encompass PAHs, biodegradation, benzo[a]pyrene, bioaugmentation, and degradation. Based on insights from our bibliometric analysis, we presented five research recommendations: in-depth exploration of degradation mechanisms for specific HMW-PAHs, thorough comprehension of microbial metabolic pathways, investigation into the toxicity and degradation products of HMW-PAHs, implementation of field experiments and scale-up applications, and establishment of long-term monitoring and assessment protocols.
