Abstract

All kinds of industries can produce a large amount of the heavy metal Mn emission, especially in the Mn steel plant production process. The assessment of Mn pollution in industrial areas is vital to human health and soil conservation. First, there are 120 samples of 0–5 cm and samples 9 of 0–40 cm of the surface soil collected from outside. Next, the soil column test is applied to study the migration and speciation regularity of Mn in 0–40 cm of soil layer, and then a forecasting model is established to verify and evaluate the Mn pollution in the study area. After the exogenous Mn enters the soil, Mn soon transforms into a more stable form in soil at 0–20 cm depth. But the residual amounts of Mn in deep soil increases with the increase of exogenous Mn. The main speciation of Mn in surface soil includes residual, oxide-bound, and organic-bound forms. Carbonate-bound form is sensitive to the increase of exogenous Mn. The exogenous Mn content has less influence on the content of oxide-bound and organic-bound forms in soils below 20 cm. The prediction model can be used to evaluate the degree of pollution of Mn in surface soil of the study area. © 2018, © 2018 Taylor & Francis Group, LLC.
