Abstract: Polycyclic aromatic hydrocarbons (PAHs) are an important class of persistent organic pollutants (POPs) that can be transported over long distances by atmospheric circulation and are endowed with low-temperature environments such as the North and South Poles and the Tibetan Plateau. Global warming accelerates the melting of snow and ice, leading to exposure to PAHs and affecting human health. Microorganisms are the main degraders of PAHs, and a large number of related studies have been reported, but the studies on PAHs-degrading microorganisms in low-temperature environments have mainly focused on the last 20 years. In this paper, the diversity of microorganisms degrading PAHs at low-temperature, the degradation mechanism and the response of biodegradation to low-temperature are systematically sorted out and reviewed, and the further research direction and prospect of microbial degradation of PAHs in low-temperature environments are envisioned, so that theoretical support can be provided for the prevention of the source and ecological remediation of PAHs contamination in low-temperature environments in the future.
