TL;DR: The improvement of industrial processing technology reducing the metal dispersion rate, the recycling of metal-containing outdated products, by-products and wastes, and the development of new substitute materials for heavy metals are possible strategies to minimize the effects of heavy metals on the authors' environment.

TL;DR: In this article, the authors studied the phytotoxicity of Brassica juncea in Cr(III)- and Cr(VI)-contaminated soils using chemical, light microscopy, scanning electron microscopy (SEM) and transmission electron microscope (TEM) analyses.

TL;DR: Investigation of potential transformation, distribution, and plant uptake of mercury compounds in soils shows that the H(2)O(2)-oxidizable mercury fraction (organically bound mercury) was the major solid-phase fraction in soils freshly contaminated with soluble mercury compounds, while cinnabar fraction was themajor solid phase fraction in soil contaminated with HgS.

TL;DR: Physiological and morphological changes of Zn-treated plants included a significant decrease in relative water content, dry weight and plant height, while Cd at higher concentrations resulted in structural changes only in stems and roots, and higher Zn (ZnT3 and ZnT4), Cd (CdT4) and Cd

TL;DR: The development of substitute materials for arsenic applications in the agricultural and forestry industries and controls of arsenic emissions from the coal industry may be possible strategies to significantly decrease arsenic pollution sources and dissipation rates into the environment.
