A procedure is described for the collection of remote marine aerosol samples by high-volume filtration, cascade impaction, dry fallout collection and rain.
Samples were analyzed quantitatively for five classes of naturally occurring
lipids (n-alkanes, wax esters, fatty alcohols, sterols, and fatty acids) and polycyclic
aromatic hydrocarbons (PAHs). Air samples (4,000-10,000 m3) were collected
on glass fiber filters under automatic control. Rain samples of 1-5 L were collected
on an event basis. Filters and rain samples were extracted with methylene chloride.
The extracts were fractionated into discrete chemical classes by silca-gel absorption
chromatography. The fractions were derivatized if necessary and analyzed by
HRGC and HRGC/MS. A second fiter extraction was required for
fatty acid salt analysis. Internal standards were used to quantify recoveries
and concentrations. Mean recoveries relative to the internal standards were
96.5% for C12-C36 n-alkanes, 96.4% for C12-C30 n-fatty acids, 92.5% for C12-C30
n-fatty alcohols and 93.3% for cholesterol. Typical blanks and concentrations
for remote marine aerosol and rain samples are described and compared with
other methods used in coastal marine, rural and suburban sampling locations.
