Percent recovery based on spiked amounts
measured of each metal
in the distillate matrix. Samples were collected from the aerosol
using four different tubing condensation and impinger combinations,
as depicted in Figure 1C. IMP = impingers only, OR-IMP = acetone rinse of tubing + acidic
aqueous impinger, OR-AR-NI = acetone rinse of tubing + aqueous rinse
of tubing + no impinger, and AR-OR-IMP = aqueous rinse + acetone rinse
2nd + acidic aqueous impinger. Colors indicate the contribution of
individual solvent or impinger components to the total metal signal
for each sample: green = organic (acetone) rinse, blue = aqueous rinse,
and yellow = aqueous impinger. All data has a matched procedural blank
subtracted.
