type of plant and soil physicochemical properties (Shahid et al. 2017). Cr does not have a specialised transporter; therefore, it enters plants mostly through ion channels of essential ions (specic and non-specic). It accumulates mainly in plant roots with only a minor amount translocat-ing to shoots (Shahid et al. 2017).
