Critical key points in dinamic olfactometry studies

włącz .

P21Ip   The quality and technical development of an olfactometry laboratory is not free of setbacks and deviations, which are often ignored or even unknown. These can be found in every step of the laboratory procedure, selection and calibration of panelists, sampling, olfactometry analysis and results.

   After twenty years of experience and being participating in a proficiency test since 2010, the factors that may influence in our successful performance were analyzed. The results of this analysis lead to a general review of the other activities and processes of the laboratory.

ILC20   Once again, the German company Olfasense is behind the organization of the 2020 proficiency test for Dynamic Olfactometry according to the European Standard EN 13725. The registration period fo this test has started and organizers invite laboratories from different countries to participate in this ILC2020 test.

   The EN 13725 interlaboratory comparison test allows odour laboratories all around the world to demonstrate compliance with their performance requirements and compare the performance of any laboratory internationally. This is essential for those laboratories that maintain ISO 17025 accreditation.

Evaluation of odour annoyance through repetitive surveys - Evidence from a case study

włącz .

P14I1   One way to assess odour nuisance is to apply a survey to the area of influence of an activity that potentially impacts the surrounding community. Repeated surveys were carried out in neighbours of the waste water treatment plant at Chimbarongo, Chile, during the years 2017 and 2018, using the VDI3883/1 model questionnaire.

   In parallel, an odour impact measurement was carried out by means of field inspection, using a simplified methodology of VDI3940/1. Odour hour frequencies were generally determined well below the German regulatory threshold of 10%, which was also supported by ex-ante odour dispersion modeling.
