Abstract
Objectionable odors of stack emissions from pulp mills have been traditionally associated with sulfur compounds. Concentrations of identified sulfur compounds are not considered dangerous to health of the community. In this study of stack gases, qualitative identification has been made of the presence of: benzo[a]-anthracene, benzo[a] pyrene, benzo[e]pyrene, benzo[g, h, i] perylene, chrysene, coronene, fluoranthene, and pyrene. Tentatively identified were: anthanthrene, anthracene, phenanthrene and vanillan.
