Abstract
<p class="first" id="d9704084e91">Microplastic pollution has become an emergency issue
in the global environment. However,
little is known about the occurrence and distribution of microplastics in agroecological
system. In this study, we investigated the pollution of microplastics in vegetable
farmlands in suburb of Wuhan, central China. Results showed that the abundance of
microplastics ranged from 320 to 12,560 items/kgdw. Microplastic pollution adjacent
to the suburban roads was about 1.8 times as serious as that in the residential areas.
Microplastics with size less than 0.2 mm were dominated, reaching 70% in total. The
main types of microplastics were fibers and microbeads. Moreover, polyamide (32.5%)
and polypropylene (28.8%) were the main types of polymer. This study proclaims the
occurrence and characteristics of microplastic pollution in typical farmland soils
of suburb land. It may provide significant basis for subsequent research about microplastics
contaminant in the terrestrial ecosystem.
