[Effects of mixture of 22 kinds of volatile organic compounds on human body at different temperature].
Ten healthy volunteers were exposed to mixture of 22 kinds of volatile organic compounds with concentrations of zero to 10 mg/m3 at the temperature of 18, 22 and 26 C, respectively in an artificial climate room for 60 minutes a day and six days week for two consecutive weeks to study their effects on human bodies. Results showed that quality of indoor air decreased significantly, odor intensity increased, number of the subjects who need more ventilation increased, and irritation to eyes, nose and skin intensified under the mixture concentration of 10 mg/m3 and at temperature of 26 degrees C. No significant changes in psychological tests, tear film stability and cytological studies were found. Room temperature at 26 degrees C has a significant synergetic effects on human health. Therefore, quality of indoor air can not be evaluated only by organic compounds polluted in air, but by meteorological conditions.
