APPLICATION OF STABILIZING AGENTS IN CONTAMINATED SOILS OF OLD MINING AREAS
Abstract
Soil pollution by potentially toxic elements (As, Sb, Cu, Zn, Pb) near the mining areas has become a serious environmental problem. These risk elements can be released into the environment, causing a risk to human health. Stabilized pollution in various materials may constitute an additional risk in the long term. Organic acids play an important role in mobilizing contaminants. In the present work, various stabilizing agents (iron nanoparticles - nanoscale zerovalent iron (nZVI), amorphous manganese oxide (AMO), biochar (BC), natural and synthetic zeolites) were investigated in terms of their stabilizing potential under simulated rhizosphere conditions and their consequences in the mineral composition of samples. One of the aims of this work was to understand the reactivity of potential sorbents in contaminated soils of the abandoned Sb-deposit and subsequent mobility of arsenic and antimony by one-step pot experiments using citric and acetic acid. Another goal of this work was to determine the effectiveness of Aspergillus niger and Neosartorya fischeri strains producing organic acids (citric acid, oxalic acid, acetic acid) in bioleaching and bioaccumulation of Cu, Zn and Pb from mining waste from tailings pond.
