The use of catchment areas for the study of elemental mobilities is discussed with particular reference to two catchments in north-east Scotland. Underlying geology has considerable influence on their respective stream water compositions, although total annual solute output ultimately depends on the quantity of stream runoff. Tremendous fluctuations in stream water chemistry occur during storms which, it has been suggested, are due to the pathways taken by storm water through chemically contrasting soil horizons. Field sampling of this soil throughflow storm component and laboratory studies involving the leaching of undisturbed soil cores (taken at various depths down the profile) support this conclusion. Relationships between iron, aluminium and organic matter in stream water are discussed in detail. Full use of the available analytical facilities has been made with modifications to existing methods and development of new methods undertaken where necessary.
