Sea-surface microlayer samples were obtained in the North sea, by collecting droplets ejected by bubbles bursting at the sea-surface. The samples were analysed for some trace and major elements, mainly by neutron activation and atomic absorption spectrophotometry, and the results were compared with those from samples of bulk seawater taken at the same time. For any element X , the results may be expressed as a concentration factor related to Na, thus: The CF values for trace elements showed wide fluctuations from sample to sample. The only two elements for which relatively unambiguous CF values were obtained were Sc (from 2.5 to 100) and Pb (from 140 to 410). Other CF values were obtained for Co (up to 76). Zn (<50), La (up to 3000) and Ce (up to 500). The major ions Mg, Cl, K, Ca, Br, gave CF values between 0.54 and 2.2 in all cases measured. It is concluded that large enrichments of some trace elements can occur in the surface microlayer, but enrichment of major ions has not been observed. Concentrations of about 30 trace elements in particulate form in bulk seawater were measured in the course of the study.
