Enrofloxacin (EF) and cadmium (Cd) were independently adsorbed in soils.
EF accelerated and increased Cd bioaccumulation in earthworms.
At high concentration EF (10 mg kg−1) was toxic to earthworms.
EF enhanced Cd induced oxidative stress, and increased burrowing and respiration.
EF did not affect the Cd induced increase in metallothionein in earthworms.
