    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Title Manual for calculating critical loads of heavy metals for soils and surface waters; preliminary guidelines for environmental quality criteria, calculation methods and input data

Abstract Methodologies are described for calculating critical loads of lead, cadmium, copper, zinc, nickel, chromium and mercury for soils and surface waters. The aspects which are discussed are: selection of a computation model, determination of environmental-quality criteria for the metals, collection of input data, and assessment of the sources of uncertainty. The computation models described are based on the concept of equilibrium partitioning between dissolved and adsorbed phases in soil, surface water and sediment compartments in a steady-state situation. Application examples show that present loads of heavy metals in Europe may exceed critical loads, especially for lead, cadmium, copper and zinc.
