A new passive sampling system for monitoring SO2 in the atmosphere

摘要: A new all-season passive sampling system for monitoring SO2 in the atmosphere has been developed laboratory and validated field. The unique features this include a newly designed sampler rain shelter, which allows to be installed field facing downwards. An equation associated with meteorological parameters is used calculate rates. This extensively tested lab (temperature from −37 32 °C, relative humidity 20 95%, wind speed 0.5 150 cm/s) all seasons' climates. accuracy of concentrations obtained use was higher than 85% compared those continuous analyzers. Based on 1-month exposure, can monitor ranging 0.1 120 ppb. © 1997 John Wiley & Sons, Inc. Field Analyt Chem Technol 1: 307–314,
