Several industrial by-products may be used as amendments to reduce arsenic availability in contaminated areas, hence contributing to phytoremediation processes. This study was conducted aiming to evaluate red mud (RM) and a mixture containing 75% of RM + 25% of phosphogypsum (PG) (hereafter, RMPG) a...
