Abstract Plastic debris is unavoidably released into the ecosystems, and their physicochemical mechanical qualities deteriorate when exposed to environment. This, ultimately, leads generation of tiny fragments plastic, which are known as nanoplastics (<1000 nm) microplastics (<5 mm). Over past few years, pollution synthetic polymers has been reported in almost all compartments environment across globe. It regarded a hazard both human health natural systems. In addition, act vectors for contaminants they can adsorb accumulate from seawater. The accumulation plastic waste its widespread presence have drawn attention policymakers public. This global issue led creation numerous remediation solutions by innovators previous decades, either clear up old or stop entering various matrices review focused on extensive scientific research available effective techniques removing promote positive action progress this important area. Despite challenges, these offer vital opportunities, increasing awareness enhancing environmental quality. Further, article enriched incorporating bibliometric data that illustrates widely used methods matrices. According analysis, developed date (2010 2024).

Organic pollutants like per- and polyfluoroalkyl substances (PFASs) exhibit persistence, bioaccumulation, resistance to degradation, high toxicity, garnering significant attention from scholars worldwide. To better address mitigate the environmental risks posed by PFASs, this paper employs bibliometric analysis examine literature on PFASs' concentrations collected in Web of Science (WoS) database between 2019 2024. The results show that overall trend pollution research is relatively stable increasing. In addition, study also summarizes status traditional PFASs across different media typical freshwater basins. It analyzes surface water, sediment, aquatic organisms, elucidating their distribution characteristics potential sources. While perfluorooctanoic acid (PFOA) perfluorooctane sulfonic (PFOS) levels water environments are declining annually, short-chain substitutes emerging as primary pollutants. Short-chain frequently detected whereas long-chain tend accumulate sediments. more likely concentrate protein-rich organs tissues. presence largely influenced human activities, such metal plating, fluoride industry development, industrial wastewater discharge. Currently, development China faces a complex dilemma, entangled policy legal constraints, production demands, use new alternatives, regulation restriction, creating vicious cycle. Breaking deadlock necessitates continuous active scientific particularly PFOS, with an emphasis detailed investigations sources sinks. Furthermore, ecological health risk assessments were conducted using Risk Quotient (RQ) Hazard (HQ) methods. Comprehensive comparison indicates (such PFOA) majority basins at low-risk level (RQ < 0.1 or HQ 0.2), PFOS some medium-risk (0.1 RQ 1), no basin high-risk level. adsorption removal approaches analyzed, revealing combination multiple treatment technologies novel integrated technology holds excellent prospects for PFASs.

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants that pose significant toxicity risks to humans ecosystems. Traditional advanced oxidation processes using boron-doped diamond (BDD) anodes degrade PFAS in wastewater effectively but suffer from slow kinetics high energy costs, limiting commercial application. This study introduces a hybrid process combining cathodic electro-Fenton (EF), anodic via BDD anode, membrane distillation (MD) improve perfluorooctanoate (PFOA) degradation efficiency reduce use. Increasing the current density 50 500 A/m2 significantly raised concentration of produced H2O2 0.25 mM 2.3 mM, accelerating PFOA mineralization. At A/m2, no mineralization occurred EF/BDD process, while EF/BDD-MD achieved 45% due increased electrolytic cell. 95% Findings reveal EF-generated •OH radicals assist degradation, BDD(•OH) anode was primary driver, driving 80% reaction. initiated by direct electron transfer at surface, followed homogeneous heterogeneous enhancing process. The also lowered consumption, making treatment feasible for large scales.
