Sin'kov, Yu. Sapozhnikov, B. Myasoedov] The interaction of short-lived Rn-daughter products /SLDP/, viz.214Pb and214Bi dissolved in sea-water with Fe/III/ hydroxide colloids followed by flotation of combined Fe-SLDP particles at the sea-air interface subsequently generating marine aerosols enriched in214Bi and214Pb have been studied under laboratory conditions. Rate constants for attachment of214Bi and214Pb to dispersed Fe/III/ colloids in the sea water are found to be 3.7×10−4 min−1 litre [μg/Fe/]−1 and 2.4×10−4 min−1 litre [μg/Fe/]−1, resp., /20°C/ over the concentration range of iron /III/ from 8 to 120 μg liter−1. The suggested mechanism of colloid flotation and aerosol generation might be responsible for some peculiarities of SLDP distribution in the lower marine atmosphere. Akadémiai Kiadó, 1990 Sin'kov S.
