AB  - The study on micro/nanoplastic pollution should embrace complexity. Here, we aim 
      to develop an aquatic environmental system-based comprehensive assessment 
      approach of micro/nanoplastic impacts (ACAM) to evaluate the effects of 
      micro/nanoplastics on aquatic ecosystems from the global environmental change 
      (GEC) and systematic perspective. A case study for freshwater systems in 
      Saskatchewan, Canada was conducted to evaluate the comprehensive effects of 
      multiple GEC factors (polystyrene-nanoplastics (PS-NPs), N, P, salinity, 
      dissolved organic matter (DOM), pH, hardness) on Asterococcus superbus based on 
      ten ecologically relevant endpoints. It is found that at the cellular level, 
      PS-NPs and N had an antagonistic interaction on microalgal growth in the 
      Saskatchewan freshwater ecosystem; at the molecular level, the PS-NP-induced 
      changes in lipid composition in microalgae were regulated by P, DOM, and pH. The 
      significance ranking of factor effects suggested that instead of PS-NPs 
      pollution, the fluctuations in pH level, DOM and N concentrations should be paid 
      attention to first in Saskatchewan. Under the combined impact of PS-NPs and other 
      GEC factors, microalgae at station 14 (Qu'Appelle River near highway 56) might 
      have the minimum growth rate with [-0.048, 0.094] d(-1) in Saskatchewan. These 
      findings demonstrate the efficacy of the developed ACAM in a more comprehensive 
      and context-specific assessment of MNP risks, providing new insight for the 
      management of MNP pollution.
