A STUDY ON USING PASSIVE AIR SAMPLER WITH POLYURETHANE FOAM FILTER FOR SEASONAL MONITORING PCDDs/PCDFs
In the article the application of passive air sampler with PUF filter for seasonal monitoring PCDDs/PCDFs in Hanoi is studied. The efficiency of native PCDDs/PCDFs retention on PUF filters in summer, autumn, winter and spring is very high ranging from 87.2% to 89.6%. The 13C-labeled PCDDs/PCDFs standards added to the PUF filters from the beginning of the sampling are stable. Their recovery is found from 56,5% to 146,3%, which satisfies the requirements of sampling and analytical methods. The seasonal properties and pollution level of PCDDs/PCDFs congeners in the air at the study spot are quite similar. It is shown that the passive air sampler with PUF filter is feasible and suitable for seasonal monitoring PCDDs/PCDFs in air in tropical climate.
