Low-level arsenic exposure in wood processing plants.

Low-level arsenic exposure in wood processing plants. Rosenberg MJ, Landrigan PJ, Crowley S. In October 1978, seven construction workers building a pier in Monterey, California, developed symptoms consistent with arsenic intoxication and had elevated urinary levels of arsenic. The wood used for the pier had been pressure-treated with an arsenic ...

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.

Arsenic in plants and soil

Arsenic in Soil and Plants. Arsenic naturally occurs in the soil and elsewhere in the environment and it is the 20th most common element on Earth. Industrial activity (such as mining) can increase natural levels. Arsenic is also found in CCA treated timber, termite control products and some herbicides designed for use on lawns.

ARSENIC IN GOLD LEACHING - 911 Metallurgist

May 05, 2017  Environmentally; during or after detox, the arsenic can be precipitated via ferric sulphate leaching to produce the highly insoluble ferric arsenates which will settle, sometime requires the use of flocculant, in the tailings pond. Leaching at lower pH values (10 rather than 11) will reduce the solubility of these minerals in a cyanide solution.
