The article presents an analyses of statistical uncertainty calculations to assess emission data's qualities and to filter out errors. This method provides the possibility of finding out weak points of the used emission model, as well as of determining future model improvements. Among the methods studied are the Monte Carlo method and the use of the principle of error propagation.

The article discusses the results of a study on non-methane volatile organic compounds (NMVOC) emission from solvent use in Germany. The production of solvent-containing products and its applications were viewed as the main emission sources of NMVOC. A product based approach has been applied for the calculation of the emissions from the usage of solvents. It was estimated that the total amount of emissions from such use is approximately 863 kilotons in the year 2000.

The article discusses the role of volatile organic compounds (VOC) emissions in regional and global air chemistry, as well as in global carbon and radiation balances. VOC emissions provide significant contributions to the current air pollution and are considered responsible for the formation of photo-oxidants such as ground level ozones. In response to these problems, substantial efforts have been made to understand and estimate VOC emissions from the earth surface.
