Investigation of source and infiltration of toxic metals in indoor PM2.5 using Pb isotopes during a season of high pollution in an urban area

Lead (Pb) isotope ratio has been applied in source investigation for particulate matter in size 1.5 h −1 . These findings suggested that traffic-related emission was identified as a major source of As and Cr. The 208 Pb/ 207 Pb is a useful indicator in investigating the source of As and Cd; however...

Zusammenfassung:	Lead (Pb) isotope ratio has been applied in source investigation for particulate matter in size 1.5 h −1 . These findings suggested that traffic-related emission was identified as a major source of As and Cr. The 208 Pb/ 207 Pb is a useful indicator in investigating the source of As and Cd; however, the air change rate influences the applicability of this approach on source identification.
