The emission declarations were evaluated in the summer of 2003 by the responsible state authorities in accordance with 27 BImSchG of the Federal Immission Control Act (Bundes-Immissionsschutz-Gesetz) of 2000. 

In Germany, as well as in many other industrialized countries, different efforts were made to reduce emissions by the adoption of emission standards. The technical directive TA Luft (2002) and the 17th ordinance to the German Federal Immission Control Act, BImSchG 1998 contain maximum admissible emission concentrations for various metals as shown in Tables 1.6 and 1.7.

In this paper, we will compare the data obtained in these immission measurements with the data on perceived annoyance in Hoogvliet. We will also show some data on immission measurements on samples taken at various places in the village of Zeist, our control location. 

This might be due to the fact that even without any annoying substances present, the background level of odour concentration is high. Therefore, as a control, a number of immission measurements were made on samples collected at several locations in the village of Zeist. 

The actual scope and limitations of chemical analysis of odour show that all problems can be tackled as far as emission is concerned. For immission measurements some progress is necessary, but there is no essential reason why chemical analysis would be unable to attain the desired sensitivity for all types of odorants. There is no doubt that in a few years the last difficulties will be solved. In order to achieve real control of odour nuisance, automatic measurement is necessary on a long time basis. There again some technical development is to be expected. 

Totally the discussed coverings are useful possibilities to control immissions. For a lot of farms located in villages or in a short distance to residential quarters an effective covering on the liquid manure storing tanks is the only convenient possibility to get restocking permitted. 

The dissolved concentrations of the 25 selected elements in ocean deep water are controlled by natural processes. This is not principally the case for river water and rain. The data on river water listed in Table 1.2 (according to Turekian 1969 Wedepohl 1969-1978 and Martin and Mey-beck 1979) are mainly from rivers without major contamination from industrialized areas. Suspended clay materials in the rivers have a high capacity to adsorb organic residues and metals from anthropogenic and natural sources (sewage, industrial immissions, soil extraction by acid rain water, etc.), and in this way they keep the level of dissolved metals reasonably low.
