Humans are potentially exposed to microplastics through food, drink, and air. The first two pathways have received quite some scientific attention, while little is known about the latter. We address exposure of humans indoor airborne using a Breathing Thermal Manikin. Three apartments were investigated, samples analysed FPA-µFTIR-Imaging spectroscopy followed by automatic analyses down 11 µm particle size. All contaminated with microplastics, concentrations between 1.7 16.2 particles m-3....
While it seems indisputable that potable water contains microplastics (MP), the actual concentrations are much debated and reported numbers vary many orders of magnitude. It is difficult to pinpoint cause these differences, but might be variation between waters, quantification methods, some studies did not live up rigorous analytical standards. Despite urgent need understand human exposure by drinking water, there a lack trustable methods generating reliable data. Essentially, proper MP...
Microplastics (MP) are ubiquitous within the environment, but approaches to analysis of this contaminant currently quite diverse, with a number analytical methods available. The comparability results is hindered as even for single method such Fourier transform infrared spectroscopy (FT-IR) different instruments available do not allow harmonized analysis. To overcome limitation, new free charge software tool, allowing systematic identification MP in environment (siMPle) was developed. This...
Urban and highway surfaces discharge polluted runoff during storm events. To mitigate environmental risks, stormwater retention ponds are commonly constructed to treat the water. This study is first quantify of microplastics in sediments such ponds. It applied state-of-art FTIR-methods analyse composition, size, shape, mass range 10–2000 μm. Seven serving four land uses were investigated, results related catchment characteristics, sediment organic matter content, hydraulic loading. We have...
Plastics are a recent particulate material in Earth’s history. Because of plastics persistence and wide-range presence, it has great potential being global age marker correlation tool between sedimentary profiles. In this research, we query whether microplastics can be considered among the array proxies to delimit Anthropocene Epoch (starting from year 1950 above). We present study deposition history inferred sediment profiles lakes northeastern Europe. The sediments were dated with...
In this paper, we evaluate the performance of a disc filter that retains microplastic (MP) particles from treated wastewater. A focal plane array-based Fourier transform infrared imaging technique enabled MP quantification and an in-house-built software (MPhunter) facilitated automatic analysis obtained spectra. The retained 89.7% particles, 75.6% their mass. This removal efficiency is comparable to rates reported by previous studies. However, presence unexpectedly large number whose size...
Abstract We describe a simple single‐pot method for collection and preparation of natural water microplastic analyses. The prepares samples in the same vessel (mason jars) that they are collected right up until microplastics transferred onto filters or spectroscopic windows minimized contamination, degradation, losses, while increasing recoveries throughput when compared with conventional sieving. applied it to surface grab from Mississippi River its major tributaries during after historic...
The seafloor is the major sink for microplastic (MP) pollutants. However, there a lack of robust data on historical evolution MP pollution in sediment compartment, particularly sequestration and burial rate small MPs. By combining palaeoceanographic approach state-of-the-art analytical methods identification down to 11 μm size, we present first high-resolution reconstruction from an undisturbed core collected NW Mediterranean Sea. Furthermore, investigate fate MPs once buried sediments by...
Microplastics (MPs) were quantified in Danish marine waters of the Kattegat and southernmost part Skagerrak bordering to it. is a waterbody between Denmark Sweden that receives inflow from Baltic Sea direct urban runoff metropolitan area Copenhagen Malmö. MPs measured 14 continuous transects while steaming monitoring stations. MP levels tended be highest close Copenhagen-Malmö area, albeit this was more obvious abundance particles rather than mass. The outcome measurements allowed rough...
Microplastics (MPs) overlap in size with phytoplankton and can be ingested by zooplankton, transferring them to higher trophic levels. Copepods are the most abundant metazoans among zooplankton main link between primary producers Ingestion of MPs has been investigated laboratory, but we still know little about ingestion natural environment. In this study, determined concentration characteristics down 10 μm samples, sorted calanoid copepods, fecal pellets collected Kattegat/Skagerrak Sea...
The widespread presence of microplastics (MPs) in the air and their potential impact on human health underscore pressing need to develop robust methods for quantifying presence, particularly breathable fraction (<5 μm). In this study, Raman micro-spectroscopy (μRaman) was employed assess concentration indoor airborne MPs >1 μm four environments (a meeting room, a workshop, two apartments) under different levels activity. MP spanned between 58 684 per cubic meter (MP m
High concentrations of microplastic (MP) particles have been reported in the Arctic Ocean. However, studies on high-resolution lateral and vertical transport MPs from European waters to are still scarce. Here, we provide information about compositions surface, subsurface, deeper (< 1 m, ~ 4 17–1679 m) collected at 18 stations six transects along Norwegian Coastal Current (NCC) using an improved Neuston Catamaran, COntinuos MicroPlastic Automatic Sampling System (COMPASS), situ pumps,...
The abundance and distribution of microplastics (MP) were evaluated in six “clean” sites (Italian minor islands) two “polluted” areas (near the mouth major Italian rivers). Samples MP, plankton persistent organic pollutants (POPs) collected using a manta trawl (MA) net (WP2), both lined with 333 µm mesh net. MP have been confirmed to be ubiquitous since they found at each site, showing an average density 0.3 ± 0.04 items/m3 (values ranged from 0.641 0.119 ). When comparing clean polluted...
Microplastics (MPs) are ubiquitous pollutants in the ocean, and there is a general concern about their persistence potential effects on marine ecosystems. We still know little smaller size-fraction of MPs (MPs <300 μm), which not collected with standard nets for monitoring (e.g., Manta net). This study aims to determine concentration, composition, size distribution down 10 μm Kattegat/Skagerrak area. Surface water samples were at fourteen stations using plastic-free pump-filter device (UFO...
Microplastic pollution has been confirmed in all marine compartments. However, information on the sub-surface microplastics (MPs) abundance is still limited. The vertical distribution of MPs can be influenced by water column stratification due to masses contrasting density. In this study, we investigated relation structure at nine sites Kattegat/Skagerrak (Denmark) October 2020.A CTD was used determine and pycnocline depth before sampling. Plastic-free pump-filter sampling devices were...
Hyperspectral imaging of environmental samples with infrared microscopes is one the preferred methods to find and characterize microplastics.
Microplastics prepared from commercial marine antifouling paints were weathered by UV-C irradiation representing between 25 and 101 days of real-time, outdoor exposure. Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) spectroscopy the degraded paint particles showed that weathering induced chemical changes in material, including release volatile components formation hydrophilic groups. The increased reactivity binder associated with alterations their physical properties...
Shape matters for microplastics, but its definition, particularly hyperspectral imaged remains ambiguous and inexplicit, leading to incomparability across data. Hyperspectral imaging is a common approach quantification, yet no unambiguous microplastic shape classification exists. We conducted an expert-based survey proposed set of clear concise shapes (fiber, rod, ellipse, oval, sphere, quadrilateral, triangle, free-form, unidentifiable). The categories were validated on images 11,042...
Estuarine sediments intercept and temporarily retain microplastics before they reach the marine seafloor, impacting various organisms, including key commercial species. This highlights critical need for research on microplastic exposure in these transitional environments. study provides a detailed assessment of pollution sediment compartment Limfjord, 1500 km2 large Danish fjord, introduces Polymer Hazard Index (PHI) as tool evaluating polymer-specific risks. Thirteen samples were collected,...
