Odour Monitoring 

Odour and Air Project Summaries:

Odour Assessment , Soya Processing Works, Liverpool

REC undertook a sampling programme to assess odours produced from various emission points relating to soya processing works. REC commissioned an Odour Panel and by a series of controlled dilutions an odour number was determined for the each emission. The data was used to determine which emissions required controlling to prevent odour nuisance.

Ambient Air Quality Survey for PM10, NOx and CO, York

Continuous monitoring of PM10, NO, NOx as NO2 and CO at three sites over a two week period. The analysers were set up in secure metal cabins with power supplied by the Local Authority from lampposts. The data was to be used in a dispersion modelling study to be carried out by another consultancy. REC prepared the data in the required format (15 min, 1 hour 8 hour and 24 hour averages) for direct input into the model.

Odour Sampling

Projects have been undertaken on odour emitted from distilleries for United Distillers and Whyte & Mackay.

Odour Monitoring, Bacton, Norfolk

The Environment Agency had received a number of complaints of odour nuisance from residents close to natural gas terminals at Bacton. REC was commissioned by the EA to sample and analyse ambient air from various locations around the plant to identify and measure ambient concentrations of trace volatile organic compounds, particularly organo-sulphur compounds and sulphur dioxide.  Air Quality Monitoring included the collection of grab samples were taken in Tedlar bags at various downwind distances from the gas terminals, together with an upwind control sample. Sampling over longer periods was undertaken with specially prepared adsorption tubes. Samples were subsequently analysed using a high resolution GC/MS system. The tubes were thermally desorbed and scanned by GC/MS for trace organics.
