The adverse health effects caused by indoor air pollution are termed "sick building syndrome". We report such a patient whose symptoms appeared in the workplace. A 36-year-old female office worker developed nausea and headache during working hours in a refurbished office. After eight months of seeking help at other clinics or hospitals without improvement, she was referred to our hospital. At t...

OBJECTIVES To investigate the occurrence of sick building syndrome in a tropical city, and its relation to indoor air quality and other factors. METHODS 2856 office workers in 56 randomly selected public and private sector buildings were surveyed. The study consisted of a self administered questionnaire assessing symptoms and perception of the physical and psychosocial environment, inspection...

Surveys in several office buildings have shown that crowded work places, job dissatisfaction and physical environment are the main factors affecting productivity. the data was produced and analyzed using occupational stress indicator in conjunction with the analytical hierarchical process. thermal problems, stuffiness, sick building syndrome factors and crowded work places were most frequent co...

Air quality in industrial environments has been studied since the second half of the 20th century. Well-documented results show that exposure to chemical pollutants through their consumption, production, and storage can damage workers' health. New research focusing on non-industrial environments has shown unexpected correlations between air quality and health effects. Artificial ventilation sys...

The sick building syndrome is well known among office workers and is becoming more recognised among health workers.' It is therefore important to be able to give correct advice when faced with this problem. This study provides evidence that negative ion generators are not to be recommended for this problem, especially as the data on temperature and humidity provided a good "internal control" th...

This paper reviews current literature on the associations of ventilation rates and carbon dioxide concentrations in non-residential and non-industrial buildings (primarily offices) with health and other human outcomes. Twenty studies, with close to 30,000 subjects, investigated the association of ventilation rates with human responses, and 21 studies, with over 30,000 subjects, investigated the...
