Abstract: The concent ration and disappearance of the indor volatile organic compounds(VOC) was measured by chemical mothods under two model ornamented laboratory condition. The potential mutagenicity of VOCs was measured by the micronucleus test in vicia faba leaf tips. The result s showed that the VOCs in ornamental materials had the potential mutagenicity. The result s of micronucleus test had obvious relationship comparing with the genotoxicity of mouse. The moicronucleus test in vicia faba leaf s tips and mouse bone marrow cell suggested that human were safe coming into the new ornamental room after one month. This paper recommend the sanitation standard values of the air in new ornamental houses first of all in our count ry. Our study provided the sientific basis of establishing health standard for the department of health.
