a The design of the multiple factor experiment. There were 20 replicates for the control; 10 replicates for water control (without adding organic solvents); 8 replicates for single GCFs; 50 replicates for each factor level in the multiple factor group; the total number of experimental units = 20 + 10 + 8\(\times\)12 + 3\(\times\)50 = 276. Factor combinations in 2, 5, and 8 levels are randomly selected from the full combinations by drawing 2, 5, and 8 factors from the 12 factors pool without repetition. b Analysis workflow. The normalized dissimilarity index for each multi-factor treatment is calculated based on the Euclidean distances among single factors and the randomly selected factor combinations. c Experimental microcosm and response variables measured.
