In the paper titled “Water management practices affect arsenic and cadmium accumulation in rice grains,” the “Cd and As concentration in grains in a field experiment” data of Figure 2 in page 4 appeared incorrectly in this paper. For that particular bar chart, the authors accidentally calculated the “Cd and As concentration in milled grains” as “Cd and As concentration in grains.” So the grain Cd and As concentrations were reanalyzed. And the results showed that the original data were quite different from the reanalyzed data. The trends of Cd and As concentration in rice grains among various water management practices are not affected by this. Please see the corrected Figure 2.
