AB  - A large amount of plastic waste is generated yearly worldwide, and landfills are 
      commonly used for the disposal of plastic waste. However, burying in landfill 
      does not get rid of the plastic waste but leave the problem to the future. 
      Previous works have showed that microplastics are presented in the landfill 
      refuse and leachate, which might be potential sources of microplastics. In this 
      work, characteristics of microplastic pollution in an informal landfill in South 
      China were studied. Landfill refuse, underlying soil, leachate, and groundwater 
      samples were collected from different sites within and around the landfill. 
      Results show that microplastics in the landfill refuse and underlying soil varied 
      from 590 to 103,080 items/kg and from 570 to 14,200 items/kg, respectively. Most 
      of the microplastics are fibrous, small sized, and transparent. Polyethylene 
      (PE), polypropylene (PP), and polyethylene terephthalate (PET) are major polymer 
      types. Scanning electron microscope (SEM) images and Fourier Transform Infrared 
      (FTIR) spectra of the microplastic samples indicate varying degree of weathering. 
      Microplastic abundances in the landfill leachate and groundwater ranged from 3 to 
      25 items/L and from 11 to 17 items/L, respectively. Microplastics detected in the 
      landfill leachate and groundwater are even smaller compared with those in the 
      refuse and underlying soil and their polymer types are more diverse. This work 
      demonstrated that microplastics presented in an informal landfill without 
      sufficient protection can leak out to the surrounding environment. The 
      microplastic pollution originated from informal landfills should receive more 
      attentions.
