Clusters derived from cluster analysis and factor loadings of two factors identified from factor analysis for metals on leaves during the entire sampling period. Varimax rotation was applied to factor analysis.
| Cluster | Factor 1 | Factor 2 | |
|---|---|---|---|
| Cd | 2 | 0.25 | 0.83 |
| Cu | 1 | 0.97 | 0.09 |
| Ni | 1 | 0.96 | 0.01 |
| Pb | 2 | −0.02 | 0.89 |
| Zn | 2 | 0.88 | 0.28 |
