Abstract

The cohort method was used in the study. A retrospective observation covered 4.556 males with occupational disease, manifested by lead poisoning, diagnosed during the years 1970-1992. Mortality risk analysis by causes was based on standardized mortality ratios (SMRs) calculated by person-years method. Their statistical significance was assessed by means of the test based on Poisson distribution. The general adult male population was adopted as the reference population. The state of the cohort as of 31 December 1992 was considered. The cohort accessibility was 95.6%. The study revealed increased total mortality among lead poisoned males (670 deaths; SMR = 108; 95% CI: 100-116). Significant excess mortality was observed in diseases of the digestive system (37 deaths; SMR = 148; 95% CI: 104-204), including chronic hepatitis and cirrhosis (19 deaths; SMR = 173; 95% CI: 104-270); malignant neoplasms of respiratory and intrathoracic organs (82 deaths; SMR = 135; 95% CI: 107-168), including malignant neoplasm of larynx (13 deaths; SMR = 213; 95% CI: 113-364). In the subcohort with high exposure, death risk was significantly enhanced in comparison to the general population (153 deaths; SMR = 129; 95% CI: 109-151). In addition, significant excess of malignant neoplasms was observed (43 deaths; SMR = 151; 95% CI: 109-203) including liver (4 deaths; SMR = 419; 95% CI: 114-1073) and respiratory and intrathoracic organs tumors (21 deaths; SMR = 175; 95% CI: 108-268).
