A study examined the knowledge and job skills required of persons employed in air pollution control-related occupations in Germany's public service sector. In all, 18 persons from 11 offices in 10 public institutions were interviewed. In seven cases, two people from the same institution (one performing managerial duties and the other directly involved in controlling air pollution) were interviewed. The interview findings were used to develop a total of 18 profiles of occupations in the following aspects of the field of air pollution control: policymaking, research, inspection and control, and provision of information to the public. The work performed by persons employed in air pollution control-related occupations in the public service and private sectors was compared. Occupational profiles in the public service sector were found to be more rigid than those in the industrial sector and tended to call for higher qualifications. Only 4 of 51 statements made by the interviewees regarding future occupational profiles indicated that existing qualifications would also be sufficient in the future. Appended are the interview instrument, chart of institutions/persons interviewed, classification of environmental occupational profiles, distributions of air pollution control-related tasks and competencies, and 18 occupational profiles.
