Arsenic Uptake in Plants - Bethel College

Plant samples were harvested and washed with deionized water to remove the soil, followed by a washing of 0.01 M ethylenediaminetetraacetic acid (EDTA) to complex the arsenic ions present on the surface. Cleaned plants were then separated into the root, stalk, and leaf sections to allow for tracking of the arsenic throughout the plant.

Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.
