| Abstract |
I. There was no difference in the emission compositions and levels of different brands of chain saws, and none between new and used saws. Lean fuel-air mixtures gave higher proportions of aldehydes and nitrogen oxides and lower proportions of carbon monoxide (CO) and hydrocarbons than did rich mixtures. Methanol containing fuel gave twice as much formaldehyde as did normal gasoline, and methanol was a major component of the exhaust. II. Lumberjacks complained of cough and irritation of the eyes, nose and throat. Complaints and exposure levels were aggravated by deep snow, thick stands of timber and calm weather. Felling gave higher exposure than did limbing or cutting. Exposure can be reduced by improved working methods, which are described. III. Clinical and field studies confirmed the observations of Part II. Average exposures were well below Swedish TLVs. The correlation of carboxyhaemoglobin concentration with CO exposure was too poor to permit its use as an indicator of exposure. |
