Chemical composition of fogwater collected along the California coast


Fogwater collected at both urban and nonurban coastal sites in California was found to be consistently acidic. Millimolar concentrations of NO_3^-, and fogwater pH values below 3, were observed at sites downwind of the Los Angeles basin. Fogwater composition at remote sites showed evidence of substantial Continental and anthropogenic contributions. Acid-neutralizing capacities in coastal air were found to be very low and insufficient to neutralize even small acid inputs. Chloride loss relative to its sea salt contribution was observed at sites furthest from anthropogenic sources.
