This work presents alternative extraction and analysis techniques to identify microplastics in the environment. This study aims to address previously noted issues with methods that use aggressive extraction treatments or optical microscopy identification techniques alone. Pulsed ultrasonic extraction with ultrapure water was used to remove microplastics from fish stomachs without dissolving the stomach tissues or microplastics. The technique is relatively simple and minimizes issues with…

Microplastics, an Emerging Concern: A Review of Analytical Techniques for Detecting and Quantifying Microplatics
Microplastics are ubiquitous tiny plastic particles (< 5 mm) nonbiodegradable and have large surface area in the environment or the body of living things from anthropogenic activities or
A new method for microplastic extraction from fish guts assisted by chemical dissolution.
The chemical dissolution step enables direct filter analysis for microplastics, thereby minimizing the potential loss of microplastic particles associated with manual particle transfer and enabling faster processing and subsequently a cleaner sample compared to methods involving digestion of the entire organism.
Identification of microplastics in wastewater samples by means of polarized light optical microscopy
The presented sample preparation technique with further polarized light optical microscopy (PLOM) observation positively identified the vast majority of MP particles occurring in wastewater samples of Montevideo, Uruguay, in the 70–600 μm range.

Methodology Used for the Detection and Identification of Microplastics—A Critical Appraisal
Microplastics in aquatic ecosystems and especially in the marine environment represent a pollution of increasing scientific and societal concern, thus, recently a substantial number of studies on
Isolation of microplastics in biota-rich seawater samples and marine organisms
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.
