Air dispersion computer modelling is often required as part of an Environmental Permit Application following the H1 screening or as part of a planning application. The modelling involves a mathematical simulation of how air pollutants would disperse based on hourly weather data. Air pollutants and odorous emissions can have an impact on health, ecological receptors and quality of life of sensitive receptors and therefore it is crucial to understand potential effects of these pollutants before the design of the development is frozen.
If you’re involved in the planning of a new building, industrial facility or complex you’ll need to know how it will affect the air quality around you. Crestwood Environmental can provide a range of air quality modelling options including ADMS 5.1 for air pollutants, odours and ADMS roads. We have experience in a wide range of industries including farming, anaerobic digestion, composting sites and other sites with combustion processes.
We provide air dispersion modelling on development projects in isolation or together with a range of our other in-house environmental services. By providing multiple environmental disciplines coordinated by a single Crestwood project manager, our clients benefit from a better integrated development, with a higher chance of achieving planning consent. Our approach is focused on identifying and resolving potential environmental issues at an early stage, saving clients time and money.
Dispersion Modelling Limitations
A different combination of compounds create different odours different than their individual odours at the concentration and there can also be a lack of local meteorological data. One other limitation is that you can have varying sensitivities and judgments in hedonic tone (odour concentration is not linear with odour intensity).
Some odours may also be short-lived where models are used for long term exposures (variable odour emission rates).
If you are concerned about bioaerosols at your workplace or site, Crestwood Environmental can help. Contact us today to learn more about our bioaerosol monitoring and analysis services. We operate all over the UK and beyond; our main base is located at the University of Wolverhampton Science Park in the West Midlands and we have additional staff posted in London as well as the south and north of England.
