Use of Wood Preservative and Environment Safety

The progress of wood preservative research and environment safety at home and abroad were breifly described. The toxicity of most wood preservatives and routes of intoxication were discussed. The toxicity in polluted environment brought by preparation and application processes of wood preservative, the treatment of trash antiseptic wood, and biological enrichment and food chain cycling were analyzed. Standards and safety criteria of wood preservative in American Wood Preservers' Association(AWPA)were introduced. Progress in wood preservative of low toxicity and hazardless in environment was breifly discussed. Referring to the progress in development of new preservatives, how to develop in China is suggested.
