Trace organic compounds in rain. 4. Identities, concentrations, and scavenging mechanisms for phenols in urban air and rain.

The gaseous and filterable air concentrations of a variety of phenols were determined for seven rain events in Portland, OR. The dissolved and filterable rain concentrations were also determined concurrently. The phenols in the air were found to exist virtually exclusively in the gaseous state as expected on the basis of their large vapor pressures. The fact that virtually all of the phenols found in the rain were present in the dissolved state is in agreement with the air data. The rain (dissolved) concentrations were quite high, in the microgram per liter range. Of all the constituents present in the rain samples, the most concentrated ones were phenols. The results indicate that gas scavenging is much more important than particle scavenging for phenols. Considering the rather low values of their Henry's law constants, gas scavenging is an efficient atmospheric removal process for these compounds.
