Preface: To carry out the environmental protection law of the People's Republic of China "and the law of the People's Republic of China on the prevention and control of atmospheric pollution, protect the environment, safeguard human health, standardize the monitoring method of fluoride in the air, these standards are formulated. This standard on the quality of ambient air fluoride concentration in the determination of the membrane filter fluorine ion selective electrode method "(GB/T 1543 4-1995) to revise. Since the date of implementation of this standard, the former state environmental protection agency on March 25, 1995, approved and issued by state environmental protection standards, the quality of ambient air fluoride concentration in the determination of - membrane filter, fluorine ion selective electrode method (GB/T 15434-1995).   
Description:This standard stimulates the determination of fluoride in the air of a membrane collection, fluorine ion selective electrode method.
This standard applies to hours of fluoride in the air of depth and daily average concentration of measurement.
When the sample size is 6 m < 3 > superscript, determine the lower limit of 0.9 mu g/m (superscript 3 >.
