Toxic Heavy Metals in Farm Soil | Small Farms Programs

Heavy metals such as lead are also good industrial ingredients e.g. used in car batteries. However, these heavy metals become toxic when they do not get metabolized by the body and end up accumulating in the soft tissues. Ingestion is the most common route of exposure to heavy metals. In plants, uptake of heavy metals depends on the plant species and bio-availability of the metal in the …
