Toxicologic Review of Selected Chemicals - 526
Now, clearly wood dust has some hazards......a small increase in an uncommon cancer (nasal adenocarcinoma), a risk for some reduction of lung function over decades of high level exposure, and some allergenic issues. True also, that an occasional unlucky individual could have an idiosyncratic severe reaction to almost any inhaled substance. It is not, however, a grotesque biohazard and nowhere near as dangerous to our health as the diet most of us eat or the polluted air we breathe daily, never mind driving an hour in your car. The extra inches on our waistlines are far more likely to kill us than a hobby based dust exposure. Clearly, some precaution is warranted and wise, and getting rid of dust certainly makes the hobby more enjoyable. Obsessing over the risk of inhaling a single dust particle, as Mr Pentz does, is a bit overdone, I think. To each their own.
