Опубликована: Янв. 16, 2023

Abstract Carbon neutrality by the mid-twenty-first century is a grand challenge requiring technological innovations. Biochar, traditional soil amendment which has been used for fertility improvement and contaminant remediation, revealed new vitality in this context. In review we highlight huge potential of biochar application different fields to mitigate as high 2.56 × 10 9 t CO 2 e total greenhouse gas (GHG) emissions per year, accounting 5.0% global GHG emissions. Soil applications either controlled-release fertilizer or an immobilization agent offer improved health while simultaneously suppressing CH 4 N O. Non-soil also contribute carbon unique ways. Firstly, ruminant feed decreases via physical sorption enhanced activities methanotrophs. Secondly, can be green catalyst biorefinery. Besides, additive Portland cement low impact development (LID) infrastructure lowers footprint builds resilience climate change. Furthermore, novel batteries supercapacitors energy storage purposes. Finally, adsorption capacity makes it possible being sorbent capture, utilization, (CCUS). We advocate that future research should further explore effectiveness systems change mitigation large scale applications, assess economic social viability local combat Graphical

Concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in the road environment

Environment International, Год журнала: 2022, Номер 170, С. 107618 - 107618

Опубликована: Ноя. 3, 2022

Tire wear particles (TWP) are assumed to be one of the major sources microplastic pollution environment. However, many previously published studies based on theoretical estimations rather than field measurements. To increase knowledge regarding actual environmental concentrations, samples were collected and analyzed from different matrices in a rural highway environment characterize quantify TWP other traffic-derived non-exhaust particles. The sampled included road dust (from kerb in-between wheeltracks), runoff (water sediment), air. In addition, airborne deposition was determined transect with increasing distance road. Two sieved size fractions (2-20 µm 20-125 µm) by automated Scanning Electron Microscopy/Energy Dispersive X-ray spectroscopy (SEM/EDX) single particle analysis classified machine learning algorithm into following subclasses: TWP, bitumen (BiWP), markings, reflecting glass beads, metals, minerals, biogenic/organic relative number concentrations (%) showed that contained highest proportion (up 38 %). share tended higher BiWP. seasonal BiWP observed coarse (20-125 during winter, most likely studded tire use. concentration subclasses within PM80-1 decreases road, evidencing traffic as main emission source. results confirm surrounding contain microplastics both fractions. finer fraction dominated (by mass, volume, number) all sample matrices. These have high potential transported water air far away source can contribute inhalable (PM10) This highlights importance including also future investigations.

Wastewater-treatment plants (WWTPs) are considered significant point sources of microplastics (MiP) in the receiving waters; MiP release is poorly estimated developing countries. abundance, recovery efficiency and daily load to waters were explored treatment stage facilities four WWTPs Vietnam, located Ho Chi Minh City, Thu Dau Mot, Da Lat. abundance varied from 1860 items m−3 125,000 influents between 140 813 final effluents. The MiP-removal was highest Lat wastewater-treatment plant (DL WWTP), a tertiary using trickling filters followed by aerated lagoon maturation ponds for BOD nitrogen removals. lowest observed Binh Hung (BH combined sewer system conventional activated sludge processes as secondary treatment. total environment 1,840,000 d−1 at DL WWTP 77,127,000 BH WWTP.

Desalination and Water Treatment, Год журнала: 2024, Номер 317, С. 100138 - 100138

Опубликована: Янв. 1, 2024

In this study, the literature has been reviewed for following purposes: (1) to summarize land-based and marine-based sources of microplastics (MPs) in marine environment, (2) evaluate abundance MPs waters factors affecting MP waters, (3) review general polymer types, shapes, sizes colors determine dominant characteristics (4) reveal negative effects on various organisms (phytoplankton, zooplankton, corals, fish, sea turtles, seabirds). This present provides an overview sources, abundance, which may guide future plastic/MP pollution management strategies improvement removal methods from waters. Additionally, highlights presence organism environment organisms.

A Systematic Review on Microplastic Contamination in Fishes of Asia: Polymeric Risk Assessment and Future Prospectives

Environmental Toxicology and Chemistry, Год журнала: 2024, Номер 43(4), С. 671 - 685

Опубликована: Фев. 14, 2024

Microplastics (MPs) have attracted global concern because of their harmful effects on marine biota; toxic properties can negatively impact aquatic ecosystems. Fish is an essential source protein for humans, playing a crucial role in daily food intake. Until recently, MPs were addressed primarily as environmental pollutants, but they are now increasingly recognized contaminants the supply. The present review has comprehended current knowledge MP contamination freshwater and fishes Asia, including 112 peer-reviewed sources from 2016 to 2023. recorded 422 Asian (345 77 freshwater) be contaminated with MPs. Clarias gariepinus Selaroides leptolepi shown maximum environments respectively. Omnivorous carnivorous exhibited higher susceptibility ingesting Benthopelagic, demersal, reef-associated habitats identified more prone accumulation. In both environments, China highest number species among all countries. Pollution indices indicated high environments. A prevalence fibers was fishes. Black- blue-colored <500 µm-1 mm size found dominantly. Polyethylene terephthalate polyethylene prevalent plastic polymers fish, Overall, served comprehensive understanding concentrations variations between species, feeding habits, geographic locations, which pivotal addressing pressing challenges, protecting human health, fostering sustainability efforts face escalating pollution.
