The purpose of this paper is to review the toxicological, environmental and physical properties of TCMTB and Busan 1030. They are an active ingredient and antisapstain product, respectively, produced by Buckman Laboratories for the wood protection industry. The toxicity of TCMTB and Busan 1030 has been assessed in a few species of mammals, birds, and aquatic animals. While TCMTB and Busan 1030 appear to be effective antisapstain agents, a critical evaluation of their toxicological and environmental impacts is hindered by a lack of access to full research reports. The evaluation in this paper has been based almost solely on information received in summary form from Buckman Laboratories.
In addition, there are a variety of important data gaps in the toxicological evaluation of these materials. No information was located on their carcinogenic, teratogenic, mutagenicity or long term feeding effects. In addition, the fate of these substances in air, water, soil and biota was not available. Finally, the solvents, surfactants, emulsifiers and impurities in TCMTB and Busan 1030 could not be confidently characterized. Without this information, the original of the toxic effects of TCMTB and Busan 1030 cannot be properly assessed.
