Atmospheric microplastic pollution
… field of research on theatmospheric transport of microplastic and its potential terrestrial and oceanicsource. Taking atmospheric deposition samples from the French Pyrenees Iwas able to illustrate the first atmospheric transport of microplastics of at least95km using hysplit4 back trajectory …

Evaluating non-point source microplastic pollution and its impact on biota in the Huron River
<p>Contaminants of emerging concern (CECs), like microplastics and pharmaceuticals, are a growing threat to aquatic ecosystems across the globe. Microplastics can be transported into waterways through a myriad of sources, including point sources such as wastewater treatment plants (WWTPs) and …

Microplastic pollution in the deep sea ecosystem: a study from the Rockall Trough, North East Atlantic Ocean
… has been growing environmental concern regarding microplastics. Despite the continued and increasing inputs of plastics into the environment, studies reveal lower than expected concentrations in surface waters. More recently reports have emerged documenting high concentrations of microplastics on …

Southeast Michigan wastewater treatment plants as potential sources of microplastic pollution in the Rouge River and Huron River
<p>Plastic pollution is a global issue affecting the health and stability of freshwater and marine environments. Microplastics can be introduced into waterways from a variety of sources, such as agricultural runoff, anthropogenic litter, and wastewater treatment plants (WWTPs). To determine whether …

The fate and impacts of microplastics in marine systems
Microplastic pollution prevails in marine habitats globally and is now regarded as one of the leading threats to marine biodiversity. Despite the recent increase in microplastic studies, there are a number of key areas that remain largely understudied. Furthering our knowledge of where and why …

Microplastics chemical characterization, regional distribution, and effects on biota
… analysis of the environmental effects of microplastics, with a focus on nurdles (pre-production microplastics) and microfibers . The opening section provides an overview of the pervasive nature of microplastic, and the current methodology used to describe its environmental impact. Chapter …

Abundance and composition of microplastics in surface waters and sediments of five south-central Lake Ontario tributaries
… the Great Lakes every year. Most of this is microplastic, tiny plastic particles less than five millimeters in length or diameter. Microplastic pollution is a growing environmental concern in the Great Lakes where these particles can affect aquatic life as well as humans if ingested. To …

Effects of anthropogenic change on animal cognition and emotion
… of human-induced environmental change: oceanic microplastic pollution. Microplastic exposure prevented hermit crabs from approaching and entering a new shell, which was better than their current shell. These results suggest that microplastics disrupt animal cognition (resource assessment and …

Microplastics in saltmarshes: developing extraction methods and examining past accumulation
… biota. However, the sources and accumulation of microplastics on saltmarshes have not yet been subject to detailed research. These environments have the potential to resolve the temporal evolution of plastic pollution since production began, and improve understanding of their fate in the coastal …

Estimating microplastic concentrations in surface water using satellite-based turbidity measurements: a case study on the New River, VA
Microplastic (<5 mm) pollution in rivers poses a threat to ecosystems and human livelihood around the world, yet the methods used to quantify and monitor their occurrence, distribution, and transport are highly limited. A substantial portion of plastics make their way into rivers through a variety …

Downstream Dilemma: Navigating Microplastic's Impact on Freshwater Symbiosis in the Anthropocene
… of miniscule plastic particles known as microplastics. Due to the inherent proximity to sources of anthropogenic waste, concerns of microplastic pollution and its impact on freshwater ecosystems have recently increased. Until recently, microplastic research has primarily been focused on …

Determining the spatial and temporal distribution of macro- and microplastics in soil and their impact on soil function.
Microplastics are long-term anthropogenic terrestrial ecosystem stressors that are ubiquitous in the natural environment, found in all ecological niches including aquatic and terrestrial environments. Consequently, microplastics have been found within organisms and plants, where they have the …

Occurrence, characterisation and variations of microplastics and cellulose fibres in the Scottish Atlantic coastal marine environment
Over the past decade, microplastics have proven to be globally ubiquitous and<br/>widespread, and as a result are considered one of the major threats for the<br/>environment and potentially human health. In the marine coastal environment,<br/>microplastics have been widely studied. However, …

Applications of yeast display in synthetic biology with a focus on biological synthesis and recycling of plastics
… its non-biodegradable nature and the resultant microplastic pollution. Enzymes such as LC-cutinase and MHETase, as well as hydrophobin, a protein that facilitates yeast attachment to hydrophobic surfaces, were successfully co-displayed, achieving notable degradation of low-crystallinity PET. …

Studies of microplastics present in sewage sludge, effects on amended agricultural soils
… alarm and social sensitivity revealed that microplastics (MPs) are the most notable type of plastic degradation and pollution that has attracted much attention among researchers, who have detected MP traces in marine and terrestrial environments. Facing the problem of MPs accumulation that …
