Values are Mean±S.D, (n=15), ND= not detected.
Duncans Multiple Range test was used to test the significance among the means.
Means with similar letters (a, b, c, d,e, f) in a column and row are statistically similar at p < 0.01.
*Superscripts indicate accumulation of different heavy metals (mgKg^-1.dry weight) in particular organs.
**Subscripts indicate accumulation of a heavy metal (mgKg^-1.dry weight) in various organs.
