Abstract:	Many factors can influence air quality in the workplace especially physical factors (temperature, humidity, air current speed), chemical factors and biological factors. Psychological factors also play an important role in air quality. Were studied three jobs with different characteristics, office rooms. Variables taken into account: age, gender, perception of air quality, current symptoms, recorded using a questionnaire, and results of psychological tests. Symptoms present at the employees, were similar in the three locations, in particular irritation and nasal congestion, trouble concentrating. Kraepelin test was used to test the stability of attention and focused attention over time. He showed decreased number of correct answers at the end of working hours. This decrease was greater in workplaces with foul microclimate, with artificial lighting, and communication with the plant’s production area. The correlation between symptoms and psychological test shows the importance of proper environment to work, which becomes an important factor for solving tasks that require focused attention.
