Title A dispersion modelling approach to determine the odourimpact of intensive poultry production units in Ireland
The use of atmospheric dispersion modelling has become more common for the determination of odour impacts from existing poultry production facilities and the assessment of setback distances for new facilities. Setback distances for broiler, layer and turkey units were determined using the atmospheric dispersion modelling software ISCST3 and the Environmental Protection Agency (EPA, Ireland) rec...
متن کاملA dispersion modelling approach to determining the odour impact of intensive pig production units in Ireland.
It is becoming more common now to use atmospheric dispersion models to predict where odour nuisance is likely to occur near pig units. An odour threshold concentration of 1 OuE m(-3) is the level at which an odour is detectable by 50% of screened panellists. A new odour annoyance criterion (C(98,1-h) (98%-ile, 1-h average odour concentration) < or = 4.3 OuE m(-3)) was developed in this study an...
متن کاملOdour and ammonia emissions from intensive poultry units in Ireland.
Odour and ammonia emissions were measured from three broiler, two layer and two turkey houses in Ireland. The broiler units gave a large range of odour and ammonia emission rates depending on the age of the birds and the season. A considerable variation between the odour and ammonia emission rates was evident for the two layer units which may have been due to the different manure handling syste...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولOdour and ammonia emissions from intensive pig units in Ireland.
Odour and ammonia emissions were measured at four intensive pig units in Ireland. Odour samples were collected on-site and analysed for odour concentration using an olfactometer. Ammonia concentrations in the exhaust ventilation air were measured using a portable sensor. The geomean odour emission rates over the four pig units were 17.2, 44.4, 4.3, 9.9 and 16.8 ou(E) s(-1) animal(-1) for dry so...
