Although the presence of nanoplastics in aquatic and terrestrial ecosystems has received increasing attention, little is known about its potential effect on ecosystem processes functions. Here, we evaluated if differentially charged polystyrene (PS) (PS-NH2 PS-SO3 H) exhibit distinct influences microbial community structure, nitrogen removal (denitrification anammox), emissions greenhouse gases (CO2 , CH4 N2 O), multifunctionality soils with without earthworms through a 42-day microcosm experiment. Our results indicated that significantly altered soil structure functions, more pronounced effects for positively PS-NH2 than negatively H. Ecologically relevant concentration (3 g kg-1 ) inhibited both denitrification anammox rates, while environmentally realistic (0.3 decreased rate enhanced rate. The O flux was always 6%-51% by types nanoplastics, whereas CO2 were most cases. Significantly, although global warming total increased 21%-75% earthworms. Moreover, 4%-12% 0.3 but 4%-11% 3 nanoplastics. findings provide only evidence to date rapid increase altering not also multifunctionality, it may emission their some extent.

Smart polarization and spectroscopic holography for real-time microplastics identification

Communications Engineering, Journal Year: 2024, Volume and Issue: 3(1)

Published: Feb. 17, 2024

Abstract Optical microscopy technologies as prominent imaging methods can offer rapid, non-destructive, non-invasive detection, quantification, and characterization of tiny particles. However, optical systems generally incorporate spectroscopy chromatography for precise material determination, which are usually time-consuming labor-intensive. Here, we design a polarization spectroscopic holography to automatically analyze the molecular structure composition, namely smart (SPLASH). This approach improves evaluation performance by integrating multi-dimensional features, thereby enabling highly accurate efficient identification. It simultaneously captures states-related, holographic, texture features spectroscopy, without physical implementation system. By leveraging Stokes mask (SPM), SPLASH achieves simultaneous four states. Its effectiveness has been demonstrated in application microplastics (MP) With machine learning methods, such ensemble subspace discriminant classifier, k-nearest neighbors support vector machine, depicts MPs with anisotropy, interference fringes, refractive index, morphological characteristics performs explicit discrimination over 0.8 value area under curve less than 0.05 variance. technique is promising tool addressing increasing public concerning issues MP pollution assessment, source identification, long-term water monitoring.

Conceptual model of global plants entrapping plastics

Environmental Reviews, Journal Year: 2024, Volume and Issue: 32(4), P. 470 - 484

Published: May 11, 2024

Aquatic plants, seagrasses, macrophytes, mangroves, and riparian vegetation are responsible for some of the most important ecosystem services provided on Earth. Given their role in trapping plastics along rivers, we propose a new service plastic entrapment by global plants. Although research started recently to study plastics, little is known about patterns retention remobilization through different habitats. those gaps, synthesize data plants providing conceptual model describe processes vegetation. Our results demonstrate how has pivotal entrapping across spatial temporal scales, finding higher density rather than adjacent water area. Furthermore, proposed (i.e., Plant Plastic Pathway) highlighting scales release Thus, anticipate our be starting point more sophisticated future studies, putting effort into looking at plastic–vegetation dynamics. may have crucial effect if applied hotspot area detection with clean-up mitigation actions riverine ecosystems.
