Microbial degradation and transformation of PPCPs in aquatic environment: A review

Can Lagoons Serve as a Quaternary Treatment for Micropollutants in Wastewater Treatment Plants? Recent Implications for Compliance with the New Urban Wastewater Treatment Directive

“…[12]. Specific enzymes play an important role in catalyzing the transformation of polluting compounds into less harmful substances or intermediate products [13], which can either be assimilated by other aquatic organisms or mineralized in the environment [12,41]. Notably, autotrophic ammonium-oxidizing bacteria play a significant role in the degradation of various micropollutants, such as trimethoprim, ibuprofen, and diclofenac, among others.…”

“…The efficiency of these processes varies depending on the nature of the compound, the environmental conditions, and the microbial community present. In some cases, micropollutants may be completely mineralized to carbon dioxide and water, while in others, they may be transformed into other compounds that could be less or more toxic than the original compound [12,13].…”

Comparative study of electro‐Fenton and photoelectro‐Fenton processes using a novel photocatalytic fuel cell electro‐Fenton system with g‐C3N4@N‐TiO2 and Ag/CNT@CF as electrodes

“…In recent years, there has been widespread concern because pharmaceutical and personal care products (PPCPs) have been continuously detected in the effluent of wastewater treatment plants and natural water bodies (Duan et al, 2022; Khan et al, 2022; Sengar & Vijayanandan, 2022). Even though most PPCPs are not refractory organic materials, it remains a challenge to completely remove them and make them environmentally safe (Narayanan et al, 2023; Shi et al, 2022; Singh & Suthar, 2021). Recently, researchers have obtained good results by constructing electro‐peroxone with a sacrificial iron anode to degrade PPCPs (Khavari Kashani et al, 2022).…”

Electro-Assisted Fe3+/Persulfate System for the Degradation of Bezafibrate in Water: Kinetics, Degradation Mechanism, and Toxicity

“…Since the 1970s, traces of pharmaceuticals and personal care products (PPCPs) have been detected in various water systems [1]. These substances are of increasing concern due to their potential adverse health and ecological effects on aquatic ecosystems [2].…”

“…The concentration levels of PPCPs in natural water range from ng/L to µg/L [3]. Their persistence, resistance to degradation, and potential for bioaccumulation raise concerns about the safety of aquatic and terrestrial life [1]. Among these PPCPs, fibrate pharmaceuticals are widely prescribed for lipid regulation, especially in developed countries, with an estimated annual consumption of hundreds of tons [4].…”
