In the years 1971-1974 the authors carried out investigations into the state of health of 3000 seamen employed on ships of the Polish Merchant Marine. Ten years later the authors renewed the investigations using the same methods. The only difference was in the number of seamen under investigations, then out of 3000 only 1441 were still in service on ships. The paper shows changes in distribution dynamics of the morbidity rate. It was also demonstrated that specific seamen's work environmental conditions have a significant effect on occurrence and development of different types of neuroses, hypertensive diseases and calculi of kidney and ureter.
