Both zinc oxide nanoparticles (ZnO NPs) and microplastics (MPs) were extracted from one commercial sunscreen, while other ingredients removed based on the "like dissolves like" principle. MPs further by acidic digestion of ZnO NPs using HCl characterized as spherical particles approximately 5 μm with layered sheets in an irregular shape surface. Although stable presence simulated sunlight water after 12 h exposure, promoted photooxidation producing hydroxyl radicals, a 2.5-fold increase carbonyl index degree surface oxidation. As result oxidation, more soluble fragmented to shapes sharp edges. We then compared cytotoxicity primary secondary (25–200 mg/L) HaCaT cell line viability loss subcellular damages. The cellular uptake transformed was enhanced over 20%, caused higher pristine ones, evidenced 46% lower viability, 220% lysosomal accumulation, 69% reactive oxygen species, 27% mitochondrial loss, 72% superoxide at 200 mg/L. Our study for first time explored activation derived products revealed high MPs, providing new evidence effects human health.

Microplastics and nanoplastics (M-NPLs) are ubiquitous environmentally, chemically, or mechanically degraded plastic particles. Humans exposed to M-NPLs of various sizes types through inhalation contaminated air, ingestion water food, other routes. It is estimated that Americans ingest tens thousands millions particles yearly, depending on socioeconomic status, age, gender. have spurred interest in toxicology because their abundance, nature, ability penetrate bodily cellular barriers, producing toxicological effects cells, tissues, organs, organ systems. The present review paper highlights: (1) current knowledge understanding the detrimental mouse models human cell lines, (2) organelle localization M-NPLs, underlying uptake mechanisms focusing endocytosis, (3) possible pathways involved toxicity, particularly reactive oxygen species, nuclear factor-erythroid factor 2-related 2 (NRF2), Wnt/β-Catenin, Nuclear Factor Kappa B (NF-kB)-regulated inflammation, apoptosis, autophagy signaling. We also highlight potential role increasing incubation time, spread, transport COVID-19 virus. Finally, we discuss future prospects this field.

Plastic litter is on the rise where plastic waste ends up in undesignated areas such as coastal shorelines, exposed to environmental conditions. As a result, degradation and decomposition of plastics occur, leading formation smaller fragments plastics, termed microplastics. Microplastics have recently been considered an emerging class contaminants due their ecotoxicological impact aquatic environment well soil matrix. are size less than 5 mm produced from either primary source (such pellets, beads makeup products) or secondary wear tear normal-use washing clothes textiles). Microplastic pollution spread across hydrosphere, pedosphere, atmosphere, these zones being studied for microplastic accumulation individually. However, there exists source–sink dynamic between compartments. This study reviews available literature research discusses current state fate transport explores microplastics communities, provides prospective future directions management strategies control pollution. While hydrosphere well-documented researched, studies understanding mechanism pedosphere atmosphere remain poorly understood.

Microplastics are small pieces of plastic that less than 5 mm in size and can be found most environments, including the oceans, rivers, air. These particles have negative impacts on wildlife environment. In this review literature, we analyze presence microplastics various species wildlife, fish, birds, mammals. We describe a variety analytical techniques, such as microscopy spectrometry, which identify quantify samples. addition, techniques sample preparation discussed. Summary results show present all studied, with highest concentrations often fish birds. The literature suggests widely distributed environment potential to affect wide range species.

During the first year of COVID-19 pandemic, facemasks became mandatory, with a great preference for disposable ones. However, benefits face masks health safety are counteracted by environmental burden related to their improper disposal. An unprecedented influx entering environment has been reported in last two years along implications natural environments terms biodegradability, released contaminants and ecotoxicological effects. This critical review addresses several aspects current literature regarding (bio)degradation (eco)toxicity contaminants, identifying uncertainties research needs that should be addressed future studies. While it is indisputable mask contamination contributes already alarming plastic pollution, we still far from determining its real contribution issue. The paucity studies on biodegradation ecotoxicity uncontrolled variables involved during experimental procedures, compromising eventual comparison conventional debris. Studies abundance composition mask-released (microplastics/fibres/ chemical compounds) under pre- post-pandemic conditions should, therefore, encouraged, tests considering environmentally relevant settings. To achieve this, methodological strategies developed overcome technical difficulties quantify characterise smallest MPs fibres, adsorbents, leachates increase relevancy conditions.
