[The retrospective survey of malignant tumor in weapon workers exposed to 2,4,6-trinitrotoluene].

Objective: To investigate the occupational health risk level of workers exposed to 2,4,6-trinitrotoluene (TNT) in arms industry, so as to provide basis for revising the standard of diagnosis for chronic TNT poisoning, and making protective measures for workers.

Methods: The retrospective study about the morbidity of total malignant tumor was taken on the male workers exposed to TNT over one year from eight military factories during 1970 to 1995.

Results: The morbidity of total malignant tumor in male TNT exposed workers were markedly higher than that of controls, and the relative risk (RR) was 2.
