Table 1 Series of metals ordered according to decreasing transfer coefficients (TC), translocation (TF) and bioaccumulation (BAF) factors

Treatment	TC	TF	BAF
Aminopielik	Zn > Cd > Cu > Pb > Co > Mn	Mn > Cu > Zn > Pb > Cd > Co^a	Zn > Cu > Mn > Cd > Pb > Co^a
2,4-D	Zn > Cd > Cu > Pb > Co > Mn	Mn > Cu > Zn > Cd > Co > Pb	Zn > Cd > Cu > Mn > Pb > Co
Chwastox	Zn > Cd > Cu > Pb > Co > Mn	Mn > Cu > Pb > Zn > Cd > Co^a	Zn > Mn > Cu > Cd > Pb > Co^a
MCPA	Zn > Cd > Cu > Co > Pb > Mn	Mn > Pb > Cu > Zn > Cd > Co	Zn > Cd > Cu > Pb > Co > Mn
Reference	Zn > Cd > Cu > Pb > Co > Mn	Mn > Pb > Cu > Cd > Zn > Co	Cd > Zn > Cu > Pb > Mn > Co

^aCo content in shoots was below the detection limit (1 ppb); therefore, it was assumed that respective TFs and BAFs are zero
Results for untreated reference sample, 2,4-D and MCPA [13] are included for comparison
