摘 要：Municipal solid waste（MSW） is an important destination for abandoned plastics. During the waste disposal process, large plastic debris is broken down into microplastics（MPs） and released into the ***, current research only focuses on landfill leachates, and the occurrence of MPs in other leachates has not been studied. Therefore, herein, the abundance and characteristics of MPs in three types of leachates, namely, landfill leachate, residual waste leachate, and household food waste leachate, were studied, all leachates were collected from the largest waste disposal center in China. The results showed that the average MP abundances in the different types of leachates ranged from（129 ± 54） to（1288 ± 184） MP particles per liter(particles.L-1) and the household food waste leachate exhibited the highest MP abundance（p 80%） of small MPs（20–100 μm） in landfill leachates compared to other leachates. To the best of our knowledge, this is the first study discussing the sources of MPs in different leachates, which is important for MP pollution control during MSW disposal.
