摘要

The report assesses potential worker exposures and risks to 2378 TCDD and 2378 TCDF in the production, processing, and commercial use of pulp, paper, and paper products. The report identifies the job categories in each operation and examines worker exposure via the following three exposure pathways: (1) inhalation of volatilized 2378 TCDD/2378 TCDF, (2) inhalation of particulates containing 2378 TCDD/2378 TCDF, and (3) dermal contact with pulp, paper, or sludge. Since no available personnel exposure monitoring data is available, various modeling techniques and assumptions are used to estimate exposures. A range (low and high values) of exposure and risk estimates are presented for each industry/worker scenario and exposure route. The 'low' and 'high' exposures and risks are estimated based on the lowest and highest dioxin TEQ concentrations, as reported in the 104-Mill Study, and typical to reasonable worst-case assumptions, respectively.
