The EU Water Framework Directive (WFD) requires that the ecological and chemical status of water bodies in Europe should be assessed, and action taken where possible to ensure that at least "good" quality is attained in each case by 2015. This paper

Streamwater nitrate dynamics in the River Hafren, Plynlimon, mid-Wales were investigated over decadal to sub-daily timescales using a range of statistical techniques. Long-term data were derived from weekly grab samples (1984–2010) and high-frequen

This paper introduces new insights into the hydrochemical functioning of lowland river systems using field-based spectrophotometric and electrode technologies. The streamwater concentrations of nitrogen species and phosphorus fractions were measured

Measurements of nitrate deposition and streamwater chemistry in the Tillingbourne Catchment, in Southern England, made in 1979-1982 and 1999-2001 show a 216% increase in Nitrogen leaching despite a reduction in N inputs. Both the historical and curre

The ambient pollution climate at the Liphook forest fumigation site, where coniferous trees were fumigated with SO 2 and O 3 for 4 years under field conditions, was characteristic of the fringes of the areas where pollutant effects are a problem. Exp

The release of base cations from chemical weathering is the fundamental process by which base cations lost through leaching or biological uptake are replenished. Soils with a high content of easily weatherable minerals will, in general, be readily ab

At Loch Fleet, and in other liming studies in similar environments, catchment liming is successful if an adequate amount of lime is added to hydrological source areas. Geochemical modelling demonstrates that the relatively late acidification of L. Fl

Restoring Acid Waters: Loch Fleet 1984-1990 ISBN: 9781851666638
To put the Loch Fleet project into scientific perspective, some theoretical background is needed. Loch Fleet is a recently acidified system. It once sustained a small trout population which had died out by the 1970s, and it is known that water qualit
