Plastic production and plastic pollution have a negative effect on our environment, environmental justice, climate change. Using detailed global regional plastics datasets coupled with socioeconomic data, we employ machine learning to predict that, without intervention, annual mismanaged waste will nearly double 121 million metric tonnes (Mt) [100 139 Mt 95% confidence interval] by 2050. Annual greenhouse gas emissions from the system are projected grow 37% 3.35 billion CO 2 equivalent (3.09 3.54) over same period. The United Nations treaty presents an opportunity reshape these outcomes. We simulate eight candidate policies find that just four could together reduce 91% (86 98%) gross plastic–related one-third.

Human biomonitoring of microplastics and health implications: A review

Environmental Research, Journal Year: 2023, Volume and Issue: 237, P. 116966 - 116966

Published: Aug. 25, 2023

Microplastics (MPs) are plastic particles (<5 mm) ubiquitous in water, soil, and air, indicating that humans can be exposed to MPs through ingestion of water food, inhalation.This review provides an overview the current human biomonitoring data available evaluate exposure health impact MPs.We compiled 91 relevant studies on matrices toxicological endpoints provide evidence distribution different tissues implications this have from a perspective.Human has been corroborated by detection biological samples including blood, urine, stool, lung tissue, breast milk, semen placenta. Although clearance mechanisms protecting them potentially harmful substances, risks associated include onset inflammation, oxidative stress, DNA damage, leading cardiovascular respiratory diseases, as well cancer, suggested vitro vivo studies.Based data, recurrently identified fluids, suggesting inhalation ingestion. Despite differences concentrations appear non-exposed people, accumulation pathways potential hazards is still at infant stage. Human enables assessment risks, information contribute draw management actions guidelines minimize MP release environment, thus, reduce uptake.

Drones for litter monitoring on coasts and rivers: suitable flight altitude and image resolution

Marine Pollution Bulletin, Journal Year: 2023, Volume and Issue: 195, P. 115521 - 115521

Published: Sept. 13, 2023

Multirotor drones can be efficiently used to monitor macro-litter in coastal and riverine environments. Litter on beaches, dunes riverbanks, along with floating litter river waters, spotted mapped from aerial drone images. Items detection classification are prone image resolution, which is expressed terms of Ground Sampling Distance (GSD). The GSD determined by flight altitude camera properties. This paper investigates what a suitable value for survey. Drone setup should chosen obtain between 0.5 cm/px 1.25 cm/px. Within this range, the lowest allows categorization classification, whereas highest adopted coarser census. In vision drawing up global protocol drone-based surveys, work sets ground homogenizing data collection assessments.

Microplastics dysregulate innate immunity in the SARS-CoV-2 infected lung

Frontiers in Immunology, Journal Year: 2024, Volume and Issue: 15

Published: May 13, 2024

Introduction Global microplastic (MP) pollution is now well recognized, with humans and animals consuming inhaling MPs on a daily basis, growing body of concern surrounding the potential impacts human health. Methods Using mouse model mild COVID-19, we describe herein effects azide-free 1 μm polystyrene MP beads, co-delivered into lungs SARS-CoV-2 omicron BA.5 inoculum. The effect host response to infection was analysed using histopathology RNA-Seq at 2 6 days post-infection (dpi). Results Although reduced clearance from lung, virus titres viral RNA levels were not significantly affected by MPs, overt MP-associated clinical or histopathological changes observed. However, infected revealed that exposure suppressed innate immune responses dpi increased pro-inflammatory signatures dpi. cytokine profile showed significant correlation ‘cytokine release syndrome’ signature observed in some COVID-19 patients. Discussion findings are consistent recent finding can inhibit phagocytosis apoptotic cells via binding Tim4. They also add literature suggesting dysregulate inflammatory processes specific disease settings.

Characterization of three plastic forms: Plasticoncrete, plastimetal and plastisessiles

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 895, P. 165073 - 165073

Published: June 22, 2023

Plastic forms, including plastiglomerate, pyroplastic, plasticrusts, anthropoquinas, plastistone and plastitar, were recorded worldwide. These plastic forms derive from geochemical or geophysical interactions such as heat-induced fusion with rock in campfires, incomplete combustion, water motion-driven abrasion the rocky intertidal zone, deposition hardened sediments bonding tar. Thereby, these can profoundly influence fate of plastics environment. This study characterized three novel (plasticoncrete, plastimetal plastisessiles) discovered on Helgoland island (North Sea). Plasticoncrete consisted common polyethylene (PE) polypropylene (PP) fibers concrete. Plastimetal included PE rusted metal. Plastisessiles attached to benthic substrates by sessile invertebrates (oysters polychaetes). are first composed two man-made materials. show that not only result human- environment-mediated but also biological between plastic.

In the context of marine litter monitoring, reporting weight beached can contribute to a better understanding pollution sources and support clean-up activities. However, scaling task requires considerable effort specific equipment. This experimental study proposes evaluates three methods estimate from aerial images, employing different levels categorization. The most promising approach (accuracy 80 %) combined outcomes manual image screening with generalized mean (14 g) derived studies in literature. Although other two returned values same magnitude as ground-truth, they were found less feasible for aim. represents first attempt assess using remote sensing technology. Considering exploratory nature this study, further research is needed enhance reliability robustness methods.
