and
Arsenic mobility and bioavailability in paddy soil under iron compound amendments at different growth stages of rice
The first article has been posted by the authors as public full text on RG, so you can freely download it as pdf file. Please find attached a pdf file of the second paper.
Good luck with your work and best wishes, Frank Edelmann
