Results and discussion
- Clinical signs:
- The authors report on the types of tumour and number of cases found in the workforce, and provide crude descriptions of the causes of death, of the causes of sickness-related pensioning or sickness-related transfer to other jobs, and the cases involved.
Incidences of sick-leave due to various illnesses as percentages of all sick-leaves combined were compared with corresponding figures for the whole plant. These crude comparisons suggested that sick-leaves due to respiratory diseases (infections excluded) were not more frequent among chromium oxide workers than among the workers of the whole plant in general. No conclusions about risks or etiological factors can be drawn from the descriptive data. However, the authors noted that in the spectrum of illnesses, there was no emphasis on the occurrence of chronic obstructive pulmonary disease and that no cases of skin sensitization to chromium(III) (“allergic reactions”) were found.
The third report contains data on clinical examinations of 106 workers from the chromium oxide and basic chromium sulphate production. Among the results are five cases of nasal septum perforations and six cases of pneumoconiosis. However, the chromium oxide workers were not separated from the basic chromium sulphate workers, and for most of the parameters there were no control subjects. Among the workers some had previous exposure to quartz and some were also occsionally working at the chromic acid plant, involving Cr(VI) exposure.
Due to the inadequate methodologies and mixed exposure, no conclusions can therefore be made based on these descriptive studies.
Applicant's summary and conclusion
- Conclusions:
- The three descriptive health reports presenting retrospective overvews on the causes of death, health reasons for removal to other jobs, occurrence of unfitness to work, and clinical examinations of workers from a German chromium oxide and basic chromium sulphate plant showed some health effects among the workers, but due to the inadequate methodologies and mixed exposure, no conclusions can be made based on these descriptive studies.
