Micro- and nanoplastic (MNP) pollution is a significant concern for ecosystems worldwide. The continuous generation extensive utilization of synthetic plastics have led to the widespread contamination water food resources with MNPs. These pollutants originate from daily-use products industrial waste. Remediation such essential protect human health since these ubiquitous contaminants pose serious biological environmental hazards by contaminating chains, sources, air. Various remediation techniques, including physical, chemical, sophisticated filtration, microbial bioremediation, adsorption employing novel materials, provide encouraging avenues tackling this worldwide issue. biotechnological approaches stand out as effective, eco-friendly, sustainable solutions managing toxic pollutants. However, complexity MNP presents challenges in its management regulation. Addressing requires cross-disciplinary research efforts develop implement more efficient, sustainable, scalable techniques mitigating pollution. This review explores various sources micro- resources, their impacts, strategies—including advanced approaches—and treating alleviate effects on health.

Plastic pollution is a significant environmental concern globally. Plastics are normally considered chemically inert and resistant to biodegradation. Although many papers have reported enzyme-induced biodegradation of plastics, these studies primarily limited enzymes microbial origin or engineered enzymes. This study reveals that poly(ethylene terephthalate) (PET, ∼6000 Da 100 kDa) particles plastic bottle debris (PBD, 24.9 can be efficiently degraded by mammal-origin natural phase II metabolic isozyme, glutathione S-transferase (GST), under mild conditions. The degradation efficiency PET plastics reached 98.9%, with rate 2.6 g·L–1·h–1 ambient physiological conditions at 1 atm. GST varying biological factors (i.e., temperature, light irradiation, pH, presence humic acid protein). We suggest novel mechanism for other than hydrolysis, i.e., the cleavage release monomers via nitridation oxidation. finding also function GST, previously thought only degrade small molecules (<1000 Da). method has been successfully applied in real human serum samples. Additionally, we tested confirmed ability digestive enzyme (trypsin) human-derived (CYP450). Overall, our findings provide potential new route control contribute understanding metabolism fate organisms.

Microplastics (MPs) and nanoplastics (NPs) have emerged as significant environmental pollutants with potential detrimental effects on ecosystems human health. Several studies indicate their interaction enzymes; this topic represents a multifaceted research field encompassing several areas of interest from the toxicological ecotoxicological impact MPs NPs humans wildlife to biodegradation plastics by microbial enzymes. This review aims provide critical analysis state-of-the-art knowledge enzyme carbonic anhydrase (CA), providing recent insights, analyzing gaps in field, drawing future perspectives its application. CA is widespread crucial various organisms; it for physiological processes animals, plants, bacteria. It catalyzes reversible hydration CO2, which essential respiration, acid–base balance, pH homeostasis, ion transport, calcification, photosynthesis. Studies demonstrate that can inhibit activity mechanisms including adsorption surface subsequent conformational changes. In vitro silico highlight role electrostatic hydrophobic interactions these processes. vivo present mixed results, are influenced factors like particle type, size, concentration, organism type. Moreover, potentiality esterase plastic degradation discussed. The complexity between MPs/NPs underscores need further fully understand ecological health impacts expression glimpses field.

One significant way that microplastics (MPs) are transported from the air into soil and water is through deposition. Nevertheless, little known about contributing causes geographical distribution of MPs in urban The present study determined spatial their potential ecological risk Malda City, West Bengal, India (from December 2023 to February 2024). average deposition fluxes were ranging 122.25 ± 76.96 387 89.23 n m −2 d −1 . Most found small-sized (50–100 µm) with transparent (35.51%) white (33.19%) color. dominant chemical compositions, such as PE (∼32%), PVC (∼24%), PET (∼20%), case shapes fragments (∼38%) films (∼29%) types found. geographic heterogeneity seen under investigation was mostly caused by human activity regions’ commercial nature. also affected rainfall wind speed. may provide a greater concern, according early evaluation. According this study, has major influence on source dispersion atmospheric deposited areas.
