| Abstract/Contents: | "The herbicide picloram (commonly sold under the trade names Tordon and Grazon) is typically used to kill unwanted broad-leaved plants on rangeland and pastures, in forestry, and along rights-of-way. In laboratory tests, picloram causes damage to the liver, kidney, and spleen. Other adverse effects observed in laboratory tests include embryo loss in pregnant rabbits, and testicular atrophy in male rats. The combination of picloram and 2,4-D causes birth defects and decreases birth weights in mice. Picloram is contaminated with the carcinogen hexachlorobenzene. Hexachlorobenzene, in addition to causing cancer of the liver, thyroid, and kidney, also damages bones, blood, the immune system, and the endocrine system. Nursing infants and unborn children are particularly at risk from hexachlorobenzene. Picloram is toxic to juvenile fish at concentrations less than 1 part per million (ppm). Concentrations as low as 0.04 ppm have killed trout fry. In Montana, roadside spraying of Tordon killed 15,000 pounds of fish in a hatchery 1/4 mile downstream from the Tordon treatment. Picloram is persistent and highly mobile in soil. It is widely found as a contaminant of groundwater and has also been found in streams and lakes. It is also extremely phytotoxic, and drift and runoff from picloram treatments have caused startling damage to crops, particularly tobacco and potatoes. Because of these characteristics, both the Ecological Effects Branch and the Environmental Fate and Ground Water Branch of the U.S. Environmental Protection Agency (EPA) recommended that use of picloram not be continued. These recommendations were not accepted by EPA when it evaluated picloram in 1995." |
