Abstract
Preveously the present author reported on disturbances evoked by crude oil in the crew of tankers as his first report (Rodo Kagaku Vol.32, No.12). Thereafter, animal experiments were performed, taking into consideration the living conditions, surroundings, and labor conditions of the crew. The results of pathohistological examinations were reported as the second report (Rodo Kakaku Vol.34, No.12). In this work attemps were made to observe the influences of body contamination and aspiration of generated gas during cleaning of tank residuum of tankers: Body weight, blood pressure, erythrocyte and leucocyte counts and urine protein and urobilinogen were examined. After three day continuous work decrease in body weight, elevation of blood pressure, increase in leucocyte count, excretion of protein and urobilinogen to urine were observed in all crew especially in the aged. In one subject exanthema was found in the back. These changes were recovered before the two day main work which was performed after several days. However, after the main work, changes which were similar to those observed after the preliminary work were observed. The above stated changes are to be ascribed to body contamination with crude oil residuum and aspiration of generated gas.
