摘要：Produced water is an effluent from the oil and gas industry generated in large quantities. Its disposal without prior treatment can cause negative impacts not only to the environment but also to human health. This occurs due to the water's high salinity and composition that includes heavy metals, oil particles and chemical compounds with toxic properties. Among these compounds, polycyclic aromatic hydrocarbons (PAHs) are one of the most worrying groups. PAHs are recalcitrant, carcinogenic organic pollutants that, despite their toxicity, can be removed and degraded by microalgae and cyanobacteria through three mechanisms: phycoadsorption, phycosorption and phycodegradation. Based on the aforementioned, this review aims to provide an overview of the remediation mechanisms of polycyclic aromatic hydrocarbons (PAHs) by microalgae and cyanobacteria. This review takes into account the point of view of circular bioeconomy, where the biomass of microalgae and cyanobacteria is considered a potential source of essential elements for the generation of bioproducts such as biofuels and biopolymers.
