Abstract: This paper aims to evaluate ecological benefits of maize harmful and beneficial elements in Hetao agricultural economic zone. Maize rhizosphere soil, seed, stem and leaf samples are collected from Hetao agricultural economic zone in Inner Mongolia, and the content of poisonous, harmful and beneficial elements is analyzed. The main harmful elements account for a small proportion in maize seeds and stems, and most of them are at low enrichment level; most of the beneficial elements are at low enrichment level, and only N is at high enrichment level. The content of As, Pb, Cd, Hg, Cr, Cu and As in maize rhizosphere soil is lower than the national standard, in line with the green standard, and the environment conditions of producing area are excellent. Maize in the study area is pollution-free food, which can be used as sustenance for human and animal.
