    Bruce,
      Thanks for the paper.  I was on the HOLSMEER project, which is long finished,
    that provided the funds for this saltmarsh work in Iceland, as well as others
    in the UK, Ireland and Portugal. The two British Isles sites had much larger
    Pb concentrations in Roman times than the Icelandic one. I vaguely recall
    the Portuguese site having dating problems and probably not being old enough anyway.
       I think all it adds is that it is possible to detect the influence of early metal
    working - and its effect through the atmosphere and oceans in more distant parts.
    As the timing in Iceland agrees with Scottish and Irish sources (but much weaker), the
   Icelandic
    source is clearly from Europe - as opposed to being North American.
       Later in the 20th century, it is possible to see the introduction of lead in petrol
    and even its replacement with unleaded.
    Cheers
    Phil

     Dear Phil:

     I'm a science journalist doing a breaking news story for the AAAS' ScienceNOW news
     service here in the U.S., on the attached paper by Wil Marshall of the University of
     Plymouth's putative detection of 2000 year old atmospheric lead pollution from an
     Icelandic salt marsh.

     I wonder if you would kindly take a look at it and offer some comment on it's
     significance; its methodology.  In other words, what importance is this to the history
     of climatology in regards to man-made pollution?  How does it fit the pattern of what is
     already known and what does it add to the canon?

     Many thanks, Bruce
