- Abstract
- The first measurements on the daily trend of dissolved gaseous mercury
(DGM) concentration determined in coastal and offshore waters of the
Mediterranean basin are reported. Marked daily behaviour tracking solar
radiation has been observed at the coastal sampling station with DGM
values ranging from 11.0 to 38.9 pg/l. Contrary to these observations the
DGM values in offshore water samples (11.9-20.0 pg/l) were independent of
the sampling time, thus identifying the absence of higher levels during
the hours of maximum insolation. The availability of Hg2+ substrate
necessary for the photo-reaction processes of DGM formation has been
evaluated by measuring the reactive mercury concentration. In offshore
waters the lower DGM concentrations are attributable to the substrate as a
limiting factor. The highest concentration of DOC measured in coastal
seawater, with respect to the offshore one, and weaker organic
associations. (literal)
