A mortality study was conducted in a cohort of 2,283 plywood mill workers employed for at least one year between 1945 and 1955 in this industry. There were 570 deaths in this cohort, which was only 74% of the number expected based on comparable U.S. mortality figures. A statistically nonsignificant excess of deaths was observed for lymphatic and hematopoietic cancer excluding leukemia (standard mortality ratio (SRM)=156). The greatest excess was for multiple myeloma (SRM=333). The excess mortality due to lymphatic and hematopoietic cancer excluding leukemia was highest after 20 years duration of employment and latency. The workers were potentially exposed to formaldehyde (50000), but there were no deaths due to nasal cancer. A subcohort of 818 workers involved in drying or gluing operations and exposed to formaldehyde and pentachlorophenol (87865) was also studied. Based on small numbers, statistically nonsignificant increased risks of death from Hodgkin's disease (SRM=333) and lymphosarcoma (SRM=250) were observed. The authors recommend further surveillance of the plywood mill worker cohort.
