Abstract

In the period of 1958-1979 in the files of National Cancer Register (NCR) of GDR 1,313 patients with nasal cancer (ICD 160) were registered in seven districts of the GDR. In collaboration with NCR the occupational history of 1,160 patients with nasal cancer was recorded by a questionnaire. The results suggest an increased number of tumors in several professions. Compared to about 19 expected tumors in male woodworkers the number of the observed was 70. This is a statistical significant risk of 3.6.

Abstract

68 mean values of airborne shift concentration of total dust were measured at 9 factories of woodworking industries. The values varied from 0.18 to 59.3 mg/m3 for area sampling. But at 63% of the woodworking machines with exhaustion the area sampling shift concentration of total dust reached fewer values than 5 mg/m3. This is a significant decrease of dust concentration in the last ten years.
