Biological waterquality parameters in the Reeuwijk Lakes Elfhoeven, Nieuwenbroek (1983-1992) and Klein Vogelenzang and Groot Vogelenzang (1988-1992)
The biological parameters discussed are the phytoplankton community structure, the zooplankton species composition and biomass, the abundance of macrophytes and the fish community structure in Lake…
Relationships between forest condition and natural and anthropogenic stress factors on the European scale. Pilot study
Within the framework of a pan-European evaluation of the forest condition data, the available crown condition data (defoliation) have been correlated with site-specific estimations of various stress…
Emission reductions targets for priority substances: calculation of emission reduction targets for target groups, based on environmental quality standards and emissions in 1995
Aims of this study were to calculate emission reductions (%) for policy target groups (like industry, traffic and refineries) to evaluate present agreements on emission reductions and to advise on…
A behavioral analysis of private car use by households
In this study various aspects of ownership and use of private cars by households are studied. The private car has been at the centre of discussions about environmental problems for many years.

Calculation and Mapping of Critical Thresholds in Europe: Status Report 1997
The fourth report on the Coordination Center for Effects (CCE) describes critical threshold methodologies and results which are used for the scientific support of the second nitrogen oxide protocol…
A global high-resolution emission inventory for ammonia
A global emissions inventory for ammonia (NH3) has been compiled for the main known sources on a 1°×1° grid, suitable for input to global atmospheric models.
Greenhouse Gas Emission Accounting: preliminary study as input to a joint International IPCC Expert Meeting/CKO-CCB Workshop on Comparison of Top-down versus Bottom-up Emission Estimates
Bottom-up data for carbon dioxide, methane and nitrous oxide from the official national inventories (National Communications) were compared with data from EDGAR (Emission Database for Global…
A system for monitoring SO2 dry deposition fluxes to low vegetation
The improvements of the monitoring system which has been used since 1987 are discussed. The performance of the system in due form, and the reliability and accuracy of the fluxes were evaluated by…
In comparison with the long time horizon of climate change, the time horizon of climate policy-making is by necessity much shorter. To support current climate negotiations, a methodology has been…
