Microplastics in Urban Environments: Distribution, Fate, and Transport
Microplastics (MPs) have become a growing environmental concern, particularly in urban areas where anthropogenic activities intensify their presence in ecosystems. This research investigates MPs’ distribution, fate, and transport in urban environments, focusing on stormwater retention (SWR) ponds, …

Investigating sources of microplastics and effects of plastic pollution on biofilm function in the Huron River
… effects of plastic pollution in the environment. Microplastics (MPs) are plastic particles less than 5 mm in size, and they have become ubiquitous in aquatic ecosystems. MPs enter aquatic ecosystems through non-point sources such as urbanization, runoff, or atmospheric fallout or through …

Experimental Investigation on Microplastics Biofouling Rate in an Aquatic System
Microplastics (MPs), small plastic particles under 5 millimeters, are a growing environmental concern in freshwater and marine ecosystems. They originate from numerous sources, can easily move due to their small size, and hold the potential to transport pollutants through their movements in marine …

Adsorption of Organic Pollutants onto Microplastics
<p>Microplastics (MPs) are small plastic pieces with sizes ranging from 1 mm to 5 mm in diameter. Polyethylene (PE) is a common polymer used in plastic material and eventually breaks down to MP size overtime in the environment through a process called weathering. Weathering of MPs alters their …

Investigating optical microplastic detection methods using fluorescent staining through Nile Red
Microplastics (MPs) are small pieces of plastic debris typically defined as smaller than 5mm. Given that the global environment faces a growing plastic pollution crisis, an urgent need exists for rapid, low-cost microplastic detection systems to characterize the health and environmental risk posed …

Evaluating the Dual Role of Municipal Wastewater Treatment Plants in the Removal Efficiency and Environmental Emission of Microplastics
… fate, and environmental implications of microplastics (MPs) in municipal wastewater treatment plants (WWTPs), highlighting their dual role as pollutants and vectors for hazardous contaminants. The research develops and applies a comprehensive analytical framework that integrates …

Microplastic ingestion by two estuarine-associated mullet species, Chelon richardsonii and Chelon dumerili in the Breede Estuary, South Africa
… effects to both organisms and the environment. Microplastics (MPs) are defined as solid plastic particles ≤ 5mm in size. The small size of MPs makes them extremely hazardous, as they imitate a range of food items on which organisms feed. Rivers and estuaries are links between terrestrial and …

DETERMINATION OF CONTAMINANTS IN FISHERY PRODUCTS TO SUPPORT FOOD SAFETY
… Substances (PFASs) some of which are POPs and Microplastics (MPs); these two classes have been particularly considered due to their condition of contaminants of emerging interest. The study employs advanced analytical techniques, such as Liquid Chromatography coupled to High-Resolution Mass …

Microplastics as Contaminant Vectors: Influencing the Bioaccessibility of Naphthalene from Freshwater
Microplastics (MPs) are found throughout the environment and pose risks to human health as particulate pollutants. In addition, they have the potential to transfer environmental contaminants to humans and other sensitive receptors. However, there is a paucity of information on the vector effects of …
