Soil chromium is below 100 ppm, except for the serpentinous rocks and soil near leather and metal processing industry. Irrespective of soil content, chromium is in most part inavailable to plants due to its insoluble form. Most of the chromium taken upon plants is retained in roots, minute amounts are translocated to upper plant parts, and generally no chromium can be detected in seed and fruit. Harmful effects are recorded at increased chromium concentrations. Visible observed symptoms are a nonspecific chlorosis while structural and ultrastructural changes are also possible. In certain plant species, a growth stimulating effect of chromium is observed at very low concetrations while no data are available on chromium as an essential element
