Recognition and Valuation of Odour Emissions from Agriculture - Use of Chemical Sensor Arrays

Abstract

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.
