Pollution by tobacco smoke of indoor air. Verunreinigungen der Raumluft durch Tabakrauch.

Indoor air pollution is particularly noticeable today, resulting from the improvement of ventilation in building envelopes in order to economise in heat energy, and the consequent reduction of fresh air entry, leading to poorer air quality. The article describes the effect of tobacco smoke on the indoor climate of residential and office buildings and its effects on health, particularly its effect on non- smokers, or the passive effects of smoke. Legislation already exists (in West Germany) defining the amount of pollution permissible in the workplace (maximum workplace concentrations), and recommendations are made for guidelines for the elimination of tobacco smoke from the indoor climate.
