[Ambulatory follow-up of soot dust exposed workers].

Since 1974 in a follow-up study 54 still exposed and 29 formerly exposed workers of a carbon black producing factory (Oranienburg, FRG) were asked anamnestically and investigated clinically including lung function tests and E.C.G. Evaluating our results we did not hardly find out any important pathological findings. Considering different periods of exposition there was no fundamental yearly decrease of the ventilation values of still exposed and formerly exposed workers in comparison to the normal population. An additional pulmonary care is not to be required beside the demanded occupational medical check-up.
