The relative standard deviation (RSD), used to assess the precision, was lower than 4.8%. The accuracy of this method was confirmed by the analysis of certified atmospheric particulate matter urban dust reference material SRM 1649a. This method (SS/HG-AAS) was used to determine total arsenic and arsenic (III) in three particulate matter samples. In these samples, the total arsenic concentrations varied from 3.8 to 20.0 ng m−3, while As (III) concentrations varied from 2.7 to 10.5 ng m−3. All samples were also analyzed using acid digestion in digest block with cold finger and detection for HG-AAS. A paired t-test demonstrated no significant difference (95% CL) between the results obtained using these two sample preparation procedures. The limit of quantification, calculated considering themass of particulate matter collected on every filter, was 0.6 ng m−3 for As total and 1.0 ng m−3 for As (III).Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-04-13T13:37:01Z No. of bitstreams: 1 __ac.els-cdn.com_S002626...17a4a632f2f689cc7578e1d4647a3.pdf: 128800 bytes, checksum: 57c62706f25915b01f05ca30f4472801 (MD5)Made available in DSpace on 2012-04-13T13:37:01Z (GMT).
