Research of formaldehyde concentration in indoor air surrounding woodworking places

Formaldehyde (HCHO) is classified as a ?probable human carcinogen? under condition of unusually high or prolonged exposure. The objective of this study was to measure formaldehyde mass concentrations in the air surrounding different woodworking places during machining of board-like materials. The research results have shown that formaldehyde mass concentrations in the observed furniture factory and carpentry do not exceed the allowed limit values of 0.6 mg/m3. The highest formaldehyde mass concentration was measured in the furniture shop as a consequence of indoor air conditions: high temperature, small volume and low indirect air velocity. The formaldehyde concentration in different woodworking rooms is not affected by indoor air dustiness.
