Description/Abstract

A sediment core from Southampton Water, a coastal
plain estuary, has been investigated and is shown to
provide a record of pollution following the expansion
of the Fawley oil refinery in 1949-1951. A combination
of heavy metal analyses, the first appearance of
hydrocarbon contamination, radiometric dating, and
stable Pb isotope ratios have been used to interpret
the pollution history in the core. Indications are that
following dredging activities, accompanying the
refinery expansion, there was a relatively rapid
sedimentation rate of ca. 20 mm p.a., which decreased
with time to approximately 5 mm p.a. The higher
accumulation rate is attributed to the response of the
estuary following the major capital dredging works
that occurred in 1950-1951. The accumulation rates
are used to recalculate concentration profiles to
reveal the heavy metal flux to the sediments. Lead
isotope data indicate a significant post-1950 use of
lead derived from ancient, non-U.K. (Precambrian) ores
in local industry.
