Transport and degradation of water-soluble creosote-derived compounds

Abstract

Creosote is the most extensively used insecticide and industrial wood preservative today. It is estimated that there are more than 600 wood-preserving plants in the United States, and their collective use of creosote exceeds 4.5xl0 6 kg/yr (von Rumker et al ., 1975). Creosote is a complex mixture of more than 200 major individual organic compounds with differing molecular weights, polarities, and functionalities, along with dispersed solids and products of polymerization (Novotny et al ., 1981). The major classes of compounds previously identified in creosote show that it consists of ∼85% (w/w) polynuclear aromatic compounds (PAH), ∼12% phenolic compounds, and ∼3% heterocyclic nitrogen, sulfur, and oxygen containing compounds (NSO).
