Microplastics, which are small plastic particles, have become a growing environmental concern due to their prevalence in aquatic and terrestrial environments. They persist for decades potentially centuries resistance degradation can harm organisms release toxic chemicals. There has been increasing interest developing methods removal from the environment, particularly water. Catalytic processes shown promise as potential method microplastic elimination, including biological methods, advanced oxidation processes, hydrolysis. This review article focuses on recent advances catalytic of microplastics water, various types catalysts applications. It also discusses be integrated into real-world water treatment systems microplastics. The highlights challenges opportunities associated with environment aims contribute development more effective sustainable addressing this issue. Future research should focus hybrid catalyst that combine strengths multiple improved efficiency effectiveness. Additionally, explore use natural materials may offer environmentally friendly options. Collaboration between scientists, engineers, policymakers, public will critical implementation these systems. elimination requires multifaceted approach, continued collaboration necessary develop protect health our communities.

Toxicological impact of microplastics and nanoplastics on humans: understanding the mechanistic aspect of the interaction

Frontiers in Toxicology, Год журнала: 2023, Номер 5

Опубликована: Июль 14, 2023

Plastic is a pervasive material that has become an indispensable part of our daily lives and used in various commercial products. However, plastic waste significantly impacted the environment, accumulating water land ecosystems harming all forms life. When degrades, it breaks down into smaller particles called microplastics (MPs), which can further breakdown nanoplastics (NPs). Due to their small size potential toxicity humans, NPs are particular concern. During COVID-19 pandemic, production had reached unprecedented levels, including essential medical kits, food bags, personal protective equipment (PPE), generate MPs when burned. have been detected locations, such as air, food, soil, but understanding adverse health effects limited. This review aims provide comprehensive overview sources, interactions, ecotoxicity, routes exposure, mechanisms, detection methods, future directions for safety evaluation NPs. would improve impact on environment identify ways address this global crisis.

Microplastics are often found in the greatest quantities terrestrial environments, addition to those along coasts and oceans. They may get into water bodies from a variety of different sources such as deposition atmosphere, runoff polluted land, effluent municipal treatment plants. The objective this study is conduct comprehensive evaluation existing scientific literature related microplastics wastewater. Specifically, focus on investigating possible impacts wastewater containing both aquatic biota. Additionally, attempts identify any gaps current research, with intention informing future research priorities field. A selection over 200 papers subject microplastic pollution, covering years 2000–2023, has been selected prominent database. These encompass wide range topics, including recent advancements wastewater, their origins, behaviour potential adverse various organisms animals, soil microbial communities, plants, finally humans. results showed that using for irrigation can lead presence ecosystems facilitate transmission contaminants by interacting pollutants. findings also indicate although there significant investigation marine microplastics, prevalence contamination freshwater environments comparatively limited requires greater attention better understanding fate, transport, consequences relation water, qualities, polymer composition, forms, types land use.

Mineralization of polystyrene nanoplastics in water by photo-Fenton oxidation

Journal of environmental chemical engineering, Год журнала: 2023, Номер 11(5), С. 110755 - 110755

Опубликована: Авг. 16, 2023

Wastewater treatment plants (WWTPs) have been identified as hotspots for the spread of micro(nano)plastics (MPs/NPs) in water. Advanced oxidation processes (AOPs) emerged promising alternatives tackling MPs/NPs pollution, however, number studies on this topic remains quite limited and needs further research. In study, feasibility photo-Fenton process (UV/ H2O2/ Fe3+) carried out at ambient conditions using a broad-spectrum UV-Vis lamp was investigated degradation polystyrene (PS) NPs The impact main variables process, namely initial PS concentration, Fe3+ pH, H2O2 dose particle size, evaluated. Under optimized operating ([PS NPs]0 = 20 mg L-1; [Fe3+]0 1 [H2O2]0 130 pH0 3 T 25 ºC), complete mineralization (140 nm) achieved 40 min. outstanding performance mainly due to wavelength light intensity UV-lamp employed. To best our knowledge, is first study field photoassisted AOPs reporting fast water, under conditions. According results, can be applied higher loads larger sizes by adjusting supplied oxidant extending reaction time. Hence, displays great potential producing high-quality reclaimed water and/or combined with conventional separation treat concentrate streams mineralize WWTPs.
