||A fraction of beech wood mutagenic in the Salmonella/mammalian microsome assay
||1986, Vol.58, No.3, p.227-234. 34 ref.
||Base-pair substitition mutagens were isolated from the dusts of several untreated samples of beech wood and tested for mutagenicity in the Salmonella/mammalian microsome assay. These compounds reverted Salmonella typhimurium his-TA100 in the presence of Aroclor-induced rat S9 liver extract. These mutagens were toxic to the cells when tested in a histidine-rich medium (complete medium). Mutagenicity of the non-fractionated wood-dust extracts could not be confirmed due to the presence of some inhibitory compounds. These inhibitors counteracted the reversion of bacteria when known mutagens, such as benzo(a)pyrene, aflatoxin B1 and ethyl methanesulfonate, were tested. The results indicate that beech wood-dust contains (a) mutagenic constituent(s) which may contribute to nasal cancer among woodworkers, especially in the furniture industry.
