    Monitoring Odour Emissions from Agriculture - Use of Chemical Sensor Arrays
    (2000) Maier, Barbara; Riess, Gisbert; Zeisig, Hans-Dieter; Gronauer, Andreas
    For a wide variety of reasons, odour is causing more and more problems because it disturbs residents who live close to farms. Due to the growing sensitivity of the population, the measurement of undesirable odours has become a problem that may no longer be neglected. In this contribution, results of a comparison of different ventilation sy- stems gained with a multisensor array are documented. The big advan- tage of multisensor array measurements over olfactometry lies in the continuous registration of measurement values in contrast to the few random samples taken during olfactometric measurements.

    Recognition and Valuation of Odour Emissions from Agriculture - Use of Chemical Sensor Arrays
    (2000) Maier, Barbara; Riess, Gisbert; Gronauer, Andreas
    For a wide variety of reasons, odour is causing more and more problems because it disturbs residents who live close to farms. Thus far, an as- sessment of this annoyance has only been possible with the help of the human nose. Since this olfactometric method has many shortcomings such as lack of reproducibility, subjectivity, high personnel costs, and dependence upon the daily form of the test persons, a system is being de- veloped that will allow odour to be measured with an instrument. In this article, qualitative results are documented which prove the suita- bility of the systems used.

    Use of Chemical Sensor Arrays for the Recognition and Valuation of Odour Emissions from Agriculture
    (2000) Maier, Barbara; Riess, Gisbert; Gronauer, Andreas
    For a wide variety of reasons, residents who live close to farms are claiming more and more that they are disturbed by odour emissions. Thus far, the human nose has been the only means of assessing the an- noyance caused by these emissions. Since this olfactometric method has many disadvantages such as lack of reproducibility, subjectiveness, high personnel expenses, and its dependence upon the daily form of the test persons, a system is being developed which allows odour to be measured by an instrument. This contribution presents the methods and documents initial quantitati- ve results which prove the suitability of the systems used.
