Microplastics issue have raised public concern. However, people are not very aware of the threat in their living space, urban environment. Road dust is one main sources environmental microplastics, and thus an ideal window to reveal occurrence pattern. The differences function zones, infrastructure, natural condition may pose complex effects driving characteristics microplastics road simultaneously, but rare reports studied these features at a city scale. In this study, we used Nanjing, super-large eastern China, as research area, conducted two-seasons investigation explore spatiotemporal pattern dust. abundance Nanjing reached 143.3 ± 40.8 n/m2, fragments tire wear particles whose size < 100 µm dominated morphology. temporal variation was smooth, whereas spatial distribution showed significant among different types functional zones. commercial zones heavy industrial suffered heaviest pollution dust, following residential educational & cultural 29 polymer were identified, polystyrene (PS), polyamide (PA), polyvinylidene difluoride (PVDF), cellophane predominate. light zone unexpectedly exhibited slight contamination still contained components type.

Microplastic and microfibre pollution is a global concern, however, karst areas remain understudied. Because of their properties, these anthropogenic microparticles are particularly hazardous, easily transportable, reaching also remote areas. The underground world, called dark continent, treasure information, remained the last frontier terrestrial exploration: many parts world have not yet been accessed. In hypogeal environments, closely linked to connections between surface subterranean habitats, hydrodynamics aquifer, geology, local environmental conditions. This study aims investigate, for first time, presence microplastics microfibres in unexplored caves, revealing how human activity could indirectly impact even uncontaminated environments continent. Together with speleologists, we collected investigated sediment samples from caves Abruzzo Region, Italy. Examined were counted characterized by composition, size, shape, fluorescence, colour, via microscopy spectroscopy. concentrations resulted low or absent, moreover, natural regenerated ones higher. Fibre-shape was most common. Most clear fluorescent under UV light. Pollution sources this area likely include atmospheric deposition, nearby activities, roads, garbage. These results highlight microparticle exists which species, water resources. Given link more monitoring protection needed. work encourages speleologists collect during explorations too, as rarely studied offer crucial insights into systems, potential threats, conservation needs. Future long-term studies will clarify pollutant sources, transport, effects on ecosystems.

Reliable traffic lane recognition plays a crucial role in automated vehicles, permitting precise positioning, which is critical for appropriate trajectory planning. Light Detection and Ranging (LiDAR), because of its proficient depth-estimation capabilities independence from external lighting, serves as common tool recognition. However, the efficacy LiDAR-based detection notably affected by both road marking’s conditions varying meteorological conditions.

While is known microplastics, little on the contribution wear. This two-year field study with complementary lab testing evaluates effects degradation microplastic generation in stormwater from different types: asphalt, concrete, recycled rubber pavers. Pavement specimens each site were collected underwent testing. We directly demonstrated separate showed released most testing, suggesting formulation such novel recycled-tire pavers must undergo thorough before wide application. The asphalt was susceptible rutting field, including large proportion particles. Both land-use surface characteristics influenced generation.

Microplastics (MPs) are omnipresent particles that receive special attention because of their persistent nature and potential impact on human disease the environment. Most MPs generated by degradation larger plastic items such as clothing, car tires, discarded materials. In indoor environments, where beings spend most time, aerial MP levels higher, majority fibers produced from textiles. Airborne indoors a greater danger to humans than ingested in food drink. Fragments small enough remain substantially suspended air column, airborne microparticles measured PM10 PM2.5, become available for assimilation through respiration, potentially producing various health problems. Larger act ingestion skin contact. can carry microorganisms micropollutants adsorbed surfaces, facilitating uptake survival within body.
