Bactericidal effect

According to Schönwälder et al in 2002 and Milling et al in 2005, the wood structure is not the only criterion of differentiation in their response to pollution, since the presence of certain molecules and the chemical composition, are even more than a factor in this differentiation.

For instance, Scots pine show a strong antibacterial power (Välimaa et al in 2007), even higher than other wood and plastic. In spruce, beech and poplar similar properties are observed, and slightly above or equal to polyethylene. This makes it important to consider the combination of the undifferentiated structure of wood next to the antibacterial properties of each species.
