Professor of
Applied Mathematics, Director of the Environmental Radioactivity
Research Centre, has a research career spanning more than 30
years. During which time he has published over 130 scientific
papers and research reports on applied mathematics and
environmental radioactivity and their application to dating peat
bog and lake sediment sequences and modelling pollutant
transport. He has participated in a wide range of international
environmental research programmes and secured numerous research
grants and contracts. EC projects have included AL:PE (1991-3),
AL:PE2 (1993-5), CASSARINA (1997-9), BIOMASS (1997-9) as
subcontractor and MOLAR (1997-9), Behaviour of Transuranics
(1997-9) and 210Pb and 137Cs as Tracers of Global Circulation
(1997-9) as partner.

Tasks:
ULIV uses radionuclides as tracers for studying the regional
distribution of atmospherically deposited pollutants; the
speciation of trace metals in the water column; validating models
for the transport of atmospherically deposited pollutants in
catchment/lake systems. ERRC databases on atmospheric fluxes and
their records in lake sediments are used to make reliable estimates
of 210Pb fluxes throughout Europe. Detailed comparative studies
between radionuclides and POPs, trace metals and SCPs in rainfall,
soil cores and lake sediments are used to make accurate
reconstructions of historical pollutant fluxes at sites with
established palaeolimnological records and to estimate depositional
fluxes at non-monitored sites. Trace metal speciation in the water
column is undertaken at Experimental sites to assist understanding
of bioavailability, and of transport processes through the water
column to the sediment record. At the two Experimental sites, in
the Pyrenees and Tatra Mountains, mass balances for fallout 210Pb
is established using measurements in rain, lake water, and bottom
sediments. Inventories in bulked sediment cores from different
depositional zones are used to produce distribution maps over the
bed of the lake and to calculate the total inventory in the
sediment record. The results are used to quantify catchment inputs,
and the impact of sediment focusing on palaeolimnological
records. Comparisons with similar studies of POPs and trace metals
are used to validate models of transport processes. A limited
number of sediment cores is dated by 210Pb to fill in essential
gaps in the palaeo-limnological record.
