Abstract
The purpose of this assessment was to determine the relative importance of plant design and waste physicochemical variables on human inhalation exposure and health risk resulting from hazardous waste incineration. A hypothetical waste incineration site in the northern Midwest was chosen as the primary site for analysis. This site has a population of 0.45 x 10/sup 6/ persons, with the closest individuals residing 1500 m from the incineration site. Two facility designs (liquid injection and rotary kiln) of three sizes (1, 10, and 150 x 10/sup 6/ Btu/h), each burning three generic wastes, were selected. Three levels of destruction and removal efficiency (DRE) were considered (99.0, 99.9 and 99.99% DRE). The three waste groups selected for study, in order of increasing incinerability were: (1) pesticide-related chemicals (chloroform, ethylene dichloride, hexachlorobutadiene, and 1,1,2,2-tetrachloroethane); (2) API separator sludge chemicals (arsenic, chromium, lead, and phenol) and (3) phenol/acetone distillation chemicals (toluene, pyridine, phthalic anhydride, and methyl styrene). Annual-average ground level air concentrations of representative chemical pollutants were estimated using IEM, an automated inhalation exposure methodology. Air concentrations were estimated for both stack and fugitive emissions using region-specific meteorological and climatological data. Estimates of individual and total population exposure resulting from incineration of hazardousmore » materials were calculated and estimates of risk obtained. 31 references, 36 tables.
