毒性Pentachlorophenol (PCP) is very toxic to plants and are used as preharvest defoliants and general herbicides. Their use as herbicides is currently restricted to nonagricultural uses along drainage ditches, driveways, and fencerows.
Commercial (technical) grades of PCP commonly contain manufacturing by- products, such as dioxin (HxCDD), which can be more toxic than the PCP itself. Another contaminant in PCP is HCB (Hexachlorobenzene). The use of PCP is being phased out because of the discovery of these highly toxic contaminants (9). PCP is a Restricted Use Pesticide (RUP). Restricted Use Pesticides may be purchased and used only by certified applicators.
In 1988 the EPA announced further restrictions on the use of PCP as in the pulp and paper industry where it is used in paper coatings, sizing, adhesives and in inks. Registration for use in cooling towers and for certain oil well operations was also cancelled. The 1988 regulations also required compliance with dioxin (HxCDD) concentration limits in the final product.
