the United States do. In the case of the work by McKague et al., the materials that “show weak mutagenicity but are chemically unstable and decompose under receiving water conditions” would also likely decompose in effluent treatment systems.
Literature Cited
SIR: The article by McKague et al. (1) contained important information on chlorinated organic materials produced from pulp bleaching and was rightfully published. A number of reports of Scandinavian studies of pulp mill effluents have appeared in the scientific literature, and it is always important to keep in mind that whereas pulp mills in Scandinavian countries generally do not have secondary biological treatment systems, those in
