•Subcellular distribution and chemical forms of Cd in P. yezoensis is little known.•The majority of Cd was localised in cell walls for both control and treatment groups.•Most Cd was found dominant in 1M Nacl extractable fractions for the control group.•Most Cd was found dominant in 2% HAC extractabl...
