摘要：

Particulate matter of diverse composition and morphology commonly occurred in higher concentrations in screen-collected surface microlayer (SM) samples than in the bulk water of southern Lake Michigan. Filtration experiments (0.4 nm Nuclepore) indicated that enrichment of Zn, Cd, Pb, and Cu in the SM occurred substantially in the particulate phase, especially when surface enrichments were large. Surface enrichment of total particulate matter and Zn, Cd, Pb, and Cu was related to the presence of surface accumulated material and film pressure. Chemical analysis indicated that a significant portion of the particulate Zn, Cd, Pb, and Cu in the SM may be atmospherically transported anthropogenic particulate matter. © 1979, American Chemical Society.
