Fourier transform infrared spectroscopy, and Raman spectroscopy are currently the main technologies for MP identification. Units prevalently used to express MP abundance in water, sediment, and biota are “particles per m3,”“particles per m2,” and “particles per individual,” respectively. ...
(1)C.细节理解题。根据第二段中的"Measuring 50 to 500 microns in length, microplastics come from a variety of sources, including large plastics that break down into smaller and smaller pieces. Therefore, much remains unknown about the common exis
As the number of particles per imaged wafer was not constant, measured values of counts and particle area are reported as relative changes. In counts (n) they are calculated from the number of particles in a pre-treatment image which could be matched to a particle present in the corresponding...
Polystyrene microplastics induce microbial dysbiosis and dysfunction in surrounding seawater 2021, Environment International Citation Excerpt : However, the limitations of 16S rRNA gene sequencing remain noteworthy, and related deficiencies may lead to bias in the interpretation of microbial composition and fun...

(400) installed in the middle of the supply hose (310) or discharge hose (320);By proposing an underwater microplastic pollution measurement device, its features include:The survey results are highly reliable and reproducible.This is a device specifically designed for measuring microplastics.Plastic ...
[18] reported on microplastic removal from water using magnetic extraction method. The method operated by magnetizing the plastics with Fe-coated nanoparticles which allowed the extraction of microplastics when an external magnetic field was exerted. Show abstract An improved mathematical model for a ...
The World Health Organization, WHO, already reported that microplastics (MPs) are found everywhere, in waste and fresh water, and in the air and soil. Regarding water effluents, waste-water treatment plants only minimize the problem, trapping only larger size particles. In contrast, smaller ones...
In this paper, we present a stylized dynamic interdependent multi-country energy transition model. The goal of this paper is to provide a starting point for examining the impact of uncertainty in such models. To do this, we define a simple model based on the standard Solow macroeconomic growth...
