Lead and mercury in aerosol particles collected over the South Pole during ISCAT-2000

As part of the ISCAT-2000 field study, aerosol particle samples were collected over ∼24 hr intervals at the South Pole (SP), and they were analyzed for trace elements and for selected ions important for Antarctic sulfur and nitrogen chemistry. This paper focuses on lead and mercury while a companion...

Zusammenfassung:As part of the ISCAT-2000 field study, aerosol particle samples were collected over ∼24 hr intervals at the South Pole (SP), and they were analyzed for trace elements and for selected ions important for Antarctic sulfur and nitrogen chemistry. This paper focuses on lead and mercury while a companion paper in this issue presents the results of the aerosol ion studies. The results showed that most trace metals were below their limits of detection. Two that were not were Pb and Hg. Lead was only quantified in 15 of 53 samples, and based on those data, the mean concentration of Pb would be
