“…By increasing As concentration in the soils As root concentrations ranged from 0.28 to 3.50 in P2 plants and from 0.30 to 6.2 mg As kg -1 in P0 plants (Figure 1). Similar results were found in other studies investigating the influence of P on As accumulation by wheat (Tao et al, 2006). Shoot As concentrations also rose with increasing As concentration in soil, more so for the P0 treatment.…”

“…The work that has been conducted on wheat is less extensive (Tao et al, 2006;Zhao et al, 2007), with limited information regarding soil-root, root-shoot and shoot-grain assimilation and translocation (Williams et al, 2007). In Tuscany, Italy there is extensive soil contamination with As due to base mining and processing activities (Costagliola et al, 2004).…”

In this study we have examinated the results of two experiments on the uptake and distribution of arsenic (As) in roots, shoots, and grain of wheat grown in As-polluted soils and in an unpolluted soil irrigated with As-contaminated water in absence or presence of phosphorus (P) fertilization. Arsenic concentrations in wheat samples of the two experiments are higher than those in the plants grown on uncontaminated soil. In the experiments showed in this work, it is highlighted the role of P fertilization in preventing As uptake and translocation in wheat plants. These findings could have important implications to reduce the potential risk posed to human health by As entering the food-chain.

“…Phosphate addition may either enhance [14][15][16] or suppress [10,17,18] the As uptake by plants, or even does not affect the accumulation of As compounds in plants [19][20][21][22]. Peterson et al [23] supposed that phosphate can enhance or reduce the As phytoavailability, which is dependent on the phosphate level.…”

Roxarsone (ROX) is widely used as a feed additive in intensive animal production. While an animal is fed with ROX, the As compounds in the manure primarily occur as ROX and its metabolites, including arsenate (As[V]), arsenite (As[III]), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA). Animal manure is commonly land applied with phosphorous fertilizers in China. A pot experiment was conducted to investigate the phytoavailability of ROX, As(V), As(III), MMA, and DMA in water spinach (Ipomoea aquatica), with the soil amended with 0, 0.25, 0.50, 1.0, and 2.0 g PO(4)/kg, respectively, plus 2% (w/w manure/soil) chicken manure (CM) bearing ROX and its metabolites. The results indicate that this species of water spinach cannot accumulate ROX and MMA at detectable levels, but As(V), As(III), and DMA were present in all plant samples. Increased phosphorous decreased the shoot As(V) and As(III) in water spinach but did not affect the root As(V). The shoot DMA and root As(III) and DMA were decreased/increased and then increased/decreased by elevated phosphorous. The total phosphorous content (P) in plant tissue did not correlate with the total As or the three As species in tissues. Arsenate, As(III), and DMA were more easily accumulated in the roots, and phosphate considerably inhibited their upward transport. Dimethylarsinic acid had higher transport efficiency than As(V) and As(III), but As(III) was dominant in tissues. Conclusively, phosphate had multiple effects on the accumulation and transport of ROX metabolites, which depended on their levels. However, proper utilization of phosphate fertilizer can decrease the accumulation of ROX metabolites in water spinach when treated with CM containing ROX and its metabolites.
