A review of microplastics pollution and its remediation methods: Current scenario and future aspects

Global plastic production and its use have been omnipresent since the early 19th century. The disposal of plastics undergoes breakdown due to various physicochemical biological factors that trigger formation microplastics (MPs). Due their hydrophobic properties, structural stability, functional groups, it is difficult degrade in natural habitat. presence large surface area also helps resist decay MPs. This review summarizes recent trends development MPs degradation. method includes biodegradation, types advanced oxidation processes (AOPs) such as photocatalytic oxidation, photo-degradation, electrochemical discussed potential health risk degradation products. Most methods achieved nearly satisfactory performance degraded into CO2, H20, secondary microplastic particles with persistent organic pollutants (POPs) under laboratory conditions, which studied by researchers. It evident has many challenges, therefore finding a sustainable approach an urgent need deal issue global pollution. Some suggestions highlighted toxicity detection remaining after degradation, analysis metabolites microbes secreted during bioremediation may negative impact on environment. selective specific implementation photo-catalyst useful nontoxic components.
