Brassicaceae family members often accumulate metals

• relatives like Thlaspi species are hyperaccumulators, particularly of lead

Note: they do not form mycorrhizal associations

Known to tolerate and sometimes accumulate Pb, Zn, and Cd       

Common in urban polluted sites

Used in phytoremediation studies

Limited data: related species tolerate Cu and Pb     

Considered tolerant of urban pollution

Tolerates Zn, Pb and found often in contaminated soils

Possible accumulator

Not a known hyperaccumulator

Some tolerance reported

Tolerant of Cu, Zn

Some studies show moderate metal uptake
