Project at a Glance

Title: Inventory of chlorophenol use in the forest products industry and investigation of related emissions of chlorinated dibenzodioxins and dibenzofurans

Principal Investigator / Author(s): Chinkin, Lyle R

Contractor: Systems Applications, Inc.

Contract Number: A5-125-32

Research Program Area: Emissions Monitoring & Control

Topic Areas: Stationary Sources, Toxic Air Contaminants


Polychlorinated dibenzodioxins and polychlorinated dibentofurans are chemical species known to be highly toxic and a potential threat to public health. These chemicals are both contaminants in and combustion products of chlorophenols, which are used in the forest products industry as fungicides and wood preservatives. Therefore, extensive efforts have been made by the California State Water Resources Control Board and Regional Water Quality Control Boards to document releases of chlorophenols, dioxins, and furans from forest products industrial sites to ground and surface waters. However, no formal study has been performed to assess potential releases of these substances to the atmosphere. In 1986 the California Air Resources Board (ARB) contracted with Systems Applications, Inc. to perform a thorough survey of statewide emissions of chlorophenol, dioxins, and furans to the atmosphere from forest products industrial operations. This report documents that study.
