Sea surface: fate and biological effects of mixed contaminants
This research on the microlayer (upper 50 micrometers of the sea surface) confirms that many contaminants partition at this interface. High concentrations of polynuclear aromatic and chlorinated hydrocarbons were found in the microlayer of urban bays in Puget Sound. In some cases, concentrations exceeded water quality criteria by several orders of magnitude. At the same sites, subsurface bulk water showed no detectable contamination. Fertilized neustonic eggs of sand sole (Psettichthys melanostictus), were exposed to collected microlayer samples during their first week of embryonic and larval development. Compared to the rural site and/or central Puget Sound, exposure of embryos to microlayer from several urban bay sites resulted in delayed hatching, increased embryo mortality, and kyphosis (bent spine abnormalities) in hatched larvae. 28 refs., 2 figs., 4 tabs.
