Urban regions are suggested to be the main source of microplastic pollution in rivers. Thus, we investigated the spatiotemporal distribution of microplastics in the surface water of the Lanzhou section of the Yellow River in a semiarid region and the contributions of typical sources. The average ...
Microplastics (MP) in the environment has attracted extensive attention due to their ubiquitous occurrence and potential toxic effects; but less attention has been given to the removal technologies of MP in different environmental media. This review covers the sources, ecotoxicities, and removal technol...
Here we present the source, type, and pathways of microplastics (MPs) in water (n=10) and sediment (n=17) samples collected from 17 critical locations along the Hooghly River —an eastern distributary of River Ganga in the State of West Bengal—downstream from the megacity of Kolkata up ...
microplastics primarily pose serious threats to freshwater ecosystems, causing physical and histophysiological damage similar to that in marine environments. The sources, fates, and toxicities of microplastics in freshwater ecosystems are detailed in this review. Additionally, microplastics ...
respectively. Microplastics in both surface and bottom waters were predominantly in the form of fragments, and mostly in green. The composition of microplastics in surface water was primarily poly (methyl methacrylate) (PMA), whereas in bottom water, polyethylene (PE) dominated. Positive matrix facto...
adverse effects, and quantification of emerging contaminants that have polluted the environment, such as chemical elements employed in medicine (antimony, barium, and gadolinium), microplastics in water bodies, in addition to pharmaceutical, illicit drugs, and their metabolites in wastewater and sewage ...

Methods to sample, process and analyse microplastics in the environment A number of methods to sample, isolate, characterise, identify and quantify microplastics have been developed for water and sediment. In the following sections, the most relevant methods are briefly presented. In view of the com...
Municipal wastewater has been considered as one of the largest contributors and carriers of microplastics to the aquatic environment. However, the various residential activities that generate municipal wastewater are equally significant whenever the source of microplastics in aquatic system is accounted. Howe...
For water samples, the mean microplastic abundance at KVCR mangroves was significantly higher than at Kappad (p < 0.001), Pulimudu (p < 0.001), Elathur (p < 0.001) and Ariyallur (p < 0.05). Discussion The spatial patterns of microplastics in water and sediment demonstrated significant ...
