Environmental context Plastics production has increased considerably in recent years, leading to pollution by plastics, including microplastics (comprising particles smaller than 5mm). This work addresses the issue of from urban sources and receiving waters Greater Paris. Microplastics were found all compartments investigated, namely atmospheric fallout, waste- treated water, surface water. Abstract study investigates microplastic contamination both (wastewater total fallout) water a...
Microplastic contamination of aquatic ecosystems is a high priority research topic, whereas the issue on terrestrial has been widely neglected. At same time, under human influence, such as agroecosystems, are likely to be contaminated by plastic debris. However, extent this not determined at present. Via Fourier transform infrared (FTIR) analysis, we quantified for first time macro- and microplastic an agricultural farmland in southeast Germany. We found 206 macroplastic pieces per hectare...
Environmental context Microplastics in freshwater ecosystems are an increasingly important environmental issue, with the few available studies suggesting high contamination worldwide. Reliable data on concentrations, fluxes and polymer types continental aquatic environments, including urban water systems, needed. High ecological risk polymers associated or adsorbed chemicals have to be identified, as well their effects both organisms ecosystems. Abstract Massive accumulation of plastic...
Pyrolysis-GC/MS is increasingly used to quantify microplastics (MP) in environmental samples. In general, prior analysis, purification steps are carried out reduce the matrix sediment The conventionally protocol of density separation followed by digestion organic matter does not allow for complete isolation MP from associated and mineral matter. Among pyrolysis products as indicator compounds plastic polymers, some may originate other substances present this paper, reviewed most common...
Here, microplastic atmospheric deposition data collected at an urban site during the French national lockdown of spring 2020 is compared to from same in a period normal activity. Bulk was on vegetated roof suburban campus Greater Paris and analysed for microplastics using micro-FTIR imaging methodology. Significantly lower rates were measured overall (median 5.4 MP m−2.d−1) than activity 2021 29.2 m−2.d−1). This difference however not observed smallest size class. The dominant polymers...
Global estimations state that between 0.5 and 12.7 million metric tons of plastic enter the oceans each year. They are however associated with great uncertainties due to methodological difficulties accurately quantify land-based fluxes into oceans. New studies at basin scale thus needed for better model calibrations. Here, a modelling approach based on Jambeck's statistical method field compared in order (i) Seine River (ii) characterize constrain both approaches. Despite simplicity rough...
Microplastics (MP) have been detected in almost all matrices, including drinking water, and assessing the contamination of water with this type pollution is utmost sanitary importance. This study aims to evaluate MP inlet river at three treatment plants (DWTPs) Paris region France. Each plant performs processes that are efficient for particulate matter removal such as coagulation-flocculation, sand filtration, granular activated carbon filtration. One also has a parallel file uses...
The contamination of freshwater with microplastics (MPs) has been established globally. While the analysis MPs predominantly involved spectroscopic methods for revealing particle numbers, potential employing spectroscopy mass estimation underutilized. Consequently, there is a need to enhance our understanding loads and ensure complementarity comparability various techniques accurate quantification. This study presents first comparative results on urban water samples using micro...
Microplastics contaminating drinking water is a growing issue that has been the focus of few recent studies, where major bottleneck time-consuming analysis. In this work, micro-optofluidic platform proposed for fast quantification microplastic particles, identification their chemical nature and size, especially in 1-100 µm size range. Micro-reservoirs ahead micro-filters are designed to accumulate all trapped solid particles an ultra-compact area, which enables imaging optical spectroscopy...
Recent studies have investigated the effects of hydrological conditions on dynamics microplastics (MPs) in rivers. However, no clear correlation is consistently observed. In addition, these focus sampling before and after event, neglecting MPs over course event. Given increased intensity extreme events related to climate change, an understanding fine temporal MP rivers required better estimate fluxes their contribution downstream contamination. To address this gap enhance impact...
The Seine River basin, home to a quarter of the French population, faces generation around one million tons plastic waste each year in Paris region. Despite efficient management, some it escapes systems and ends up River, contributing its pollution. Recent studies show that debris remains river due tides. This promotes accumulation on riverbanks, particularly during floods, creating historical zones areas. In this way, these plastics along with their chemical substances, pollute all...
