Description
|
This environmental certified reference material (CRM) was developed and certified by the National Institute for Environmental Studies (NIES) for the determination of multi-elements in aerosol particulate matter. The origin of this material is atmospheric particulate matter collected on filters in a central ventilating system in a building in Beijing city center. The collection period was 10 years, from 1996 to 2005. The particulate matter was recovered from the filters by mechanical vibration; a total of 3 kg was collected. The recovered material was sieved using a 32 μm sieve, and then homogenized. The sieved material (2 kg) was subdivided into 1031 pre-washed amber glass bottles with each bottle containing 1.5 g material. Then material was stabilized by 60Co irradiation (2.5 Mrad). The CRM production was conducted in accordance with ISO Guide 34. keywords: Environmental materials , particulate matter , trace elements , heavy metals |
