[Evaluation of the effects of chlorophenol-free wood antiseptics in experimental animals]

The authors report on creation of domestic chlorophenol-free preservatives for wood (EOK, K-12, Katan) in Arkhangelsk Research Institute. Application of those chemicals is cheaper than that of foreign analogs. Toxicity of the preservatives was evaluated according to morphologic and functional changes in various organs and systems of experimental animals which faced long exposure to the preservatives. The experiments proved K-12 to be the most pathogenic among others. EOK preservative fails to induce severe pathologic changes in experimental animals, demonstrated no cumulation and allergy. Katan takes intermediate place between those two.
