AB  - The potentially negative effects of microplastics (MP) on agroecosystems have 
      raised worldwide concerns. However, little is known about the negative effects of 
      MP exposure on the soil-plant system. To fill up this knowledge gap, a pot 
      experiment was set up, and two different MP types [high density polyethylene 
      (HDPE) and general purpose polystyrene (GPPS)] were used, which had four particle 
      sizes (<25, 25-48, 48-150, and 150-850 microm) at four application rates (2.5, 5, 10, 
      and 20 g MP kg(-1) soil). Some soil properties and the growth of Chinese cabbage 
      (Brassica chinensis L.) were monitored. The results showed that (1) MP 
      application with high application rates and relatively small particle sizes 
      significantly enhanced the soil urease activity, which accompanied with enhanced 
      soil pH and decreased soil available concentrations of phosphorus and potassium 
      in some cases. (2) The exposure of MP did not significantly affect the activity 
      of soil catalase regardless of their application rates and sizes. MP with 
      different application rates and small sizes significantly reduced the soil 
      sucrase activity, but the largest size of MP enhanced the activity of soil 
      sucrase. (3) GPPS at 10-20 g kg(-1) or with the sizes of <25 and 48-150 microm 
      significantly reduced the fresh weight of Chinese cabbage, but the addition of 
      HDPE had no remarkable effects on the fresh weight regarding of its application 
      rates or sizes. (4) MP with high application rates and large sizes enhanced but 
      small sizes of MP reduced the leaf soluble sugar concentration. The increasing 
      application rates of MP and small size HDPE significantly reduced the starch 
      concentration in the leaves of Chinese cabbage, however, the different sizes of 
      GPPS showed limited effects on the leaf starch. The addition of MP with 
      increasing application rates and different sizes always reduced the concentration 
      of leaf chlorophyll. These parameters regarding to plant and soil could be used 
      to assess the risks of MP pollution in the soil-plant systems. We found that the 
      risks resulting from MP pollution were MP type-dependent and particle 
      size-dependent. These findings indicate that overaccumulation of MP in the 
      agriculture may possess an ecology risk and will negatively affect the 
      agricultural sustainability and the food safety.
