AB  - Available information about the passivation effect on heavy metals (HMs) through 
      adsorption and humification during zeolite-amended composting remains limited. 
      Thus, this study explored the dynamic changes in HM-fractions (Zn, Cu, Cd, Cr and 
      Pb) during aerobic composting added with different grain-size zeolite (Fine 
      zeolite, < 0.1 mm, ZF; Coarse zeolite: 3-5 mm, ZC). Compared to the control 
      (without zeolite, CK) and ZF treatments, ZC treatment got the highest temperature 
      in the thermophilic phase, and significantly reduced the bioavailability factor 
      (BF) of HMs, especially for Cu (45.13%), Cd (16.11%) and Pb (25.49%). Redundancy 
      analysis (RDA) and structural equation models (SEMs) indicated that zeolite 
      accelerated the passivation effect on Cd and Pb through regulating the electrical 
      conductivity (EC) as a result of surface adsorption, and on Cu by influencing 
      total carbon (TC) under the function of humification. These results increase our 
      understanding of the passivation mechanisms of HMs during aerobic composting.
