The importance of debarking in mitigating the leaching of pollutants from common Swedish tree species submerged in water

Abstract

Sprinkling wood with water is a common method for protecting wood during storage, yet the polluted runoff generated by the log yard is a major drawback. To study bark's ability to leach pollutants from logs, the Picea abies, Pinus sylvestris, and Betula pubescens wood species were submerged with and without bark for 6 weeks. The water was analysed during the study for total organic carbon, phosphorus, nitrogen, colour, pH, and distillable phenols. The results showed that the leaching from carefully debarked wood is lower than that of both gently debarked wood and intact wood. Storing carefully debarked logs is a viable method for reducing pollutants in log yard runoff. © 2011 The Japan Wood Research Society.
