The transportation and accumulation of arsenic, cadmium, and phosphorus in 12 wheat cultivars and their relationships with each other

[Display omitted] •As and Cd concentrations in wheat grain differed significantly among 12 cultivars.•As and Cd in wheat grains were correlated with P in straw and grain.•A significant positive correlation was observed between root As and Cd.•Rachis may play a key role in the difference between As and Cd transport to grains. Pot experiments were conducted to investigate the difference in arsenic (As), cadmium (Cd), and phosphorus (P) uptake, accumulation, and translocation among 12 wheat cultivars and their relationships with each other in soil “naturally” contaminated with both As and Cd. As, Cd, and P concentrations in wheat grain, straw, and root differed significantly (p
