Increasing environmental pressures on the use of pesticides throughout the world will impact more on the use of all wood preservatives. In particular the use of traditional wood preservatives and methods of application are under close scrutiny. The industry is responding to the challenge of developing alternative products and systems but faces great problems due to the excellent performance and safety record of traditional preservatives. Current research in preservation is aimed at producing more so-called "environmental friendly" preservatives. Developments to date have not produced alternatives which are as effective for long term performance and still have their own associated health and environmental hazards when compared to traditional products. The problems encountered in the introduction of new preservatives are illustrated by reference to case histories. The changes in standards and improvements in processing techniques for established preservative treatments are described. The need for effective handling and containment procedures to minimise risk with new as well as traditional preservatives is discussed.
