^a-c

The Tukey test indicates significant differences (ρ < 0.05) between cities for each extraction method in columns where different letters indicate significantly different means. A p-value of less than 0.05 indicates statistically significant differences. Acidity: free fatty acids; PV: peroxide value; K237/K270: specific extinctions at 232 and 270 nm.
