  1. Note: The aluminum concentration was categorized as negative, 0.05-2.0 mg/ kg and ≥ 2.0 mg/ kg according to the three-tiered percentile distribution of the raw data. *Aluminum detection threshold for the GF-AAS was set at 0.05 mg/kg; ** In this column, the p values refer to the comparison of the mean Aluminum concentrations in each strata, using independent samples t-tests with the log-transformed (to base e) data; ***In this column, the p-values refer to the Chi-squares for trends; i.e. if p ≤ 0.05, there is a significant trend in Aluminum concentration related to the specified characteristic (see statistics for more details).
