Toxicity of airborne nanoparticles: Facts and challenges

Environment International, Journal Year: 2024, Volume and Issue: 190, P. 108889 - 108889

Published: July 18, 2024

Air pollution is one of the most severe environmental health hazards, and airborne nanoparticles (diameter <100 nm) are considered particularly hazardous to human health. They produced by various sources such as internal combustion engines, wood biomass burning, fuel natural gas combustion, their origin, among other parameters, determines intrinsic toxicity for reasons that not yet fully understood. Many constituents toxic or at least hazardous, including polycyclic aromatic hydrocarbons (PAHs) heavy metal compounds, in addition gaseous pollutants present aerosol fraction, NOx, SO2, ozone. All these compounds can cause oxidative stress, mitochondrial damage, inflammation lungs tissues, cellular organelles. Epidemiological investigations concluded may affect respiratory, cardiovascular, nervous systems. Moreover, particulate matter has been linked an increased risk lung cancer, a carcinogenic effect related DNA but inflammatory response pollutants, which release cytokines promotes proliferation pre-existing mutated cancer cells. The mechanisms behind be investigated experimentally using cell cultures animal models. Methods gathering have explored, standardized protocols needed ensure samples accurately represent chemical mixtures environment. Toxic studied models, designing realistic exposure settings challenging. air–liquid interface (ALI) system directly exposes cells, mimicking particle inhalation into lungs.

Preferential Emission of Microplastics from Biosolid-Applied Agricultural Soils: Field Evidence and Theoretical Framework

Environmental Science & Technology Letters, Journal Year: 2024, Volume and Issue: 11(2), P. 136 - 142

Published: Jan. 17, 2024

Land application of wastewater biosolids on agricultural soils is suggested as a sustainable pathway to support the circular economy; however, this practice often enriches microplastics and associated contaminants in topsoil. Wind could transport these contaminated microplastics, thereby increasing their inhalation health risks. Analyzing wind-borne sediments collected from wind tunnel experiments biosolid-applied fields, we show enrichment wind-blown sediments. We explain preferential by using theoretical framework. This framework reveals how combined effects low density weakened wet-bonding interparticle forces between soil particles lower threshold velocity, minimum velocity necessary for erosion occur. Our calculations indicate that be emitted at speeds than characteristic background soil. windspeed distribution 3 months events over bare surface, showed more 84% exceed size 150 μm, while only 23% Thus, current models fugitive dust emissions may underestimate microplastic emission potential biosolid-amended soils.

Plastics pollution exacerbates the impacts of all planetary boundaries

One Earth, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 1, 2024

SummaryPlastics are an international governance priority because of extensive and resource-intensive production, uncontrolled environmental releases, failure to control the chemicals within materials. We examine evidence that plastics have exceeded planetary safe operating space, discussing how pollution affects multiple Earth system processes along impact pathway from resource extraction production release fate impacts. Multiple lines capture complex reality these novel entities; a single boundary quantification would be detrimental. demonstrate causal links between other problems, exacerbating consequences breaching boundaries. propose biophysically defined variables for boundaries framework as way measure, monitor, mitigate global pollution. call urgent action, recognizing not only waste management problem but integrative part climate change, biodiversity, natural-resource-use policy.

Involvement of Microplastics in the Conflict Between Host Immunity Defense and Viral Virulence: Promoting the Susceptibility of Shrimp to WSSV Infection

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(31), P. 11634 - 11642

Published: July 27, 2023

As the concentration of microplastics/microspheres (MPs) in coastal and estuarine regions increases, likelihood disease outbreaks epidemics also rises. Our study investigated impact polyvinyl chloride MPs (PVC-MPs) on white spot syndrome virus (WSSV) infection shrimp. The results revealed that PVC-MPs obviously increased WSSV replication vivo, leading to a high mortality rate among larvae facilitating horizontal transmission WSSV. Furthermore, data loads detected together with qPCR, agarose gel electrophoresis, flow cytometry approaches indicated could interact prolong survival maintain virulence at different temperatures pH values. In terms host resistance, metabolomics transcriptomics analysis demonstrated exposure upregulated metabolic concentrations gene expressions associated phospholipid metabolism were innate immunity responses. Particularly, stimulated synthesis phosphatidylcholine (PC) induced lipid peroxidation. inhibition PC Stimulator Interferon Genes (STING) translocation from endoplasmic reticulum Golgi apparatus reduces expression genes (IFN-like Vago4 Vago5) regulated by STING signaling pathways, resulting significant decrease shrimp's resistance infection. Notably, recovery operation which exposed transferred MPs-free aquatic environment led decreased infectivity over time, indicating restoration antiviral properties Overall, these findings highlight promote shrimp susceptibility two aspects: immune defense viral virulence.
