surface water and sediments, the quantity of particle is generally taken as the basic
unit, i.e., the distribution of microplastics in surface water is usually described as
items m
−3 , items L
−1 , and items Km
−2 , while items kg
−1 , items m
−2 are usually
used to describe the microplastics detected in the sediment.
1.2 Sources of Microplastics
Microplastics can be divided into two categories according to their source, namely
primary microplastics and secondary microplastics [6]. The former refers to the
plastic particles that are intentionally created for some specific purposes [11], which
mainly include resin particles and microbeads [12]; the latter refers to small pieces
