BS EN 16841-1:2016EN 16841-1:2016 (E) 4 Introduction Part 1 (grid method) and Part 2 (plume method) of this European Standard describe methods for direct assessment of odours in ambient air. This Europ

21、ean Standard supplements the dynamic olfactometry method described in EN 13725 which is generally only suitable for measurement of odour emissions at source. As the practical lower detection limit is typically 10 ouE/m3, EN 13725 cannot be applied to directly determine odour exposure in the field (i

22、.e. measure faint odours at the concentration where they can just be recognized). The methods for measuring odour presented in this European Standard make direct use of odour perception, the effect of odorants on the human sense of smell. The standard involves the use of qualified human panel member

23、s in the field to directly assess the presence of recognizable odour in ambient air, and provide data that can be used to characterize odour exposure in a defined assessment area. The standard presents two key approaches summarized as follows: Part 1 (presented in this document) describes a grid met

24、hod which uses direct assessment of ambient air by panel members to characterize odour exposure in a defined assessment area. Part 2 describes a plume method to characterize the presence of odour by determining the extent of the downwind odour plume of a source. Although the ultimate application of

25、this method is in monitoring the risk of exposure to odours and the resulting odour annoyance, there is no direct relation between the presence of recognizable odours and the occurrence of odour annoyance. The process leading to odour annoyance being experienced by an individual or a community is hi

26、ghly complex. Additional investigations are necessary to establish a link between odour exposure and the risk of odour annoyance, which is profoundly influenced by odour exposure frequency, by the type and hedonic tone of the odour perceived, and by the characteristics of those exposed to the odour

27、(the receptor). The relationship between odour exposure and annoyance is not within the scope of this European Standard. The sensory methods described here are only suitable for the assessment of odour in ambient air. They are not suitable for the assessment of substances that cannot be detected by

28、sensory methods, in particular when these substances may cause health effects not directly related to their perceived smell. BS EN 16841-1:2016EN 16841-1:2016 (E) 5 1 Scope This part of the European Standard describes the grid method for the determination of the level of odour exposure in ambient ai

29、r. It provides a set of instructions for measurement of ambient odour exposure within a defined assessment area, using qualified human panel members, over a sufficiently long period of time to be representative for the meteorological conditions of that location, and hence determine the distribution

30、of the frequency of exposure to odours within the assessment area. The sources of the odorant under study may be located within or outside the assessment area. The primary application of this European Standard is to provide a common basis for evaluation of exposure to ambient odours in the member st

31、ates of the European Union. The field of application of this type of measurement is to characterize the level of odour exposure within the study area, in order to assess whether the impact of that exposure on resident population could be a justified cause for annoyance, using exposure criteria. The

32、unit of measurement of the method is the frequency of odour hours for an assessment square, defined by four measurement points as a representative value for odour exposure for local conditions, e.g. local odour sources and the meteorology of that location. This European Standard does not include: th

33、e measurement of intensity of ambient odours, the measurement of hedonic tone of ambient odours, the calculation of odour exposure in specific weather conditions in order to determine the frequency distribution of recognizable odour in an odorant plume, the calculation of estimated source emission r

34、ate from plume assessment using reverse dispersion modelling. An overview of the interaction between existing odour exposure assessment methods is given in Annex A, including grid method (Part 1), plume method (Part 2) and olfactometry according to EN 13725. 2 Normative references The following docu
