1      Links to Cancer

Wood dust has been linked to cancers, particularly of the nose.  Additionally, wood dust occupational exposure in carpenters, joiners, wood mill workers, etc. has been linked to asthma. Wood dust from hard wood species such as Oak and Beech are known carcinogens. No epidemiological data is currently available on wood dust from Australian wood species. Often wood dust exposure is accompanied by exposure to other wood treatments such as formaldehydes, pesticides and solvents which are known to cause various cancers.

2      Wood Dust Control

There are no epidemiological studies conducted on Australian wood species. Australian exposure standards are based on American species.
