TLDR
It is concluded, that surface sampling is more efficient than sampling in a deeper layer of the water column and validating the efficiency of the whole sampling process from the environment is more important than measuring only the filtration device's recovery.About:

Wastewater treatment plants act as essential sources of microplastic formation in aquatic environments: A critical review.
TL;DR: In this article , the formation mechanism of aged microplastics in wastewater treatment plants (WWTPs) is investigated and the results highlight that MPs are prone to undergo physical abrasion, biofouling, and chemical oxidation-associated weathering in WWTPs at different treatment stages and can be further decomposed into smaller secondary MPs, including in nanoplastics.

TL;DR: In this article , a microwave assisted "one-pot" matrix removal and microplastic extraction protocol was used to identify and physically characterize suspended particulate matter in the tropical Indian Ocean by means of a quantum cascade laser-based imaging routine.

TL;DR: In this paper, the Small Volume Glass Separator (SVMGS) is proposed to isolate microplastics from freshwater samples and concentrate the treated sample in a small volume, thus reducing the brine solution use and the sample transfer steps.

Transport of emerging organic ultraviolet (UV) filters in ceramic membranes: Role of polyethylene (PE) microplastics.
TL;DR: In this paper , the adsorption behavior of organic UV filters, which are commonly contained in personal care products to preserve the skin against UV radiation, onto polyethylene (PE) microplastics were systematically studied to investigate their combined effects.

TL;DR: It is suggested that WWTPs could be a sink but also a source of MP and thus can be considered to play an important role for environmental MP pollution.

Correction: Corrigendum: Ion concentration polarization-based continuous separation device using electrical repulsion in the depletion region
TL;DR: In this article, an ion concentration polarization (ICP) was used to separate micro-and nano-sized particles based on their electrophoretic mobilities, which was performed using a strong electric field in the depletion region without the use of internal electrodes.

Wastewater treatment plants as a pathway for microplastics: Development of a new approach to sample wastewater-based microplastics.
TL;DR: It is suggested that although low concentrations of microplastics are detected in wastewater effluent, WWTPs still have the potential to act as a pathway to release microplastic given the large volumes of effluent discharged to the aquatic environment.
Journal ArticleDOI
Isolation of microplastics in biota-rich seawater samples and marine organisms
TL;DR: The efficacy of using acid, alkaline and enzymatic digestion techniques in mineralizing biological material from marine surface trawls to reveal any microplastics present is investigated and it is illustrated that enzyme digestion can aid the detection of microplastic debris within seawater samples and marine biota.

Suspended microplastics in the surface water of the Yangtze Estuary System, China: First observations on occurrence, distribution
TL;DR: Wang et al. as mentioned in this paper extracted suspended microplastics from the Yangtze Estuary and East China Sea via a floatation method and classified them according to shape and size under a stereomicroscope.
