This paper reports on the results of an odour sources and emissions investigation project at the Rutherford Industrial Estate (RIE), located in New South Wales (NSW), Australia. The project is referred to as the 'Rutherford Odour Investigation Project'. Odours emitted from the estate have been a source of complaints from the surrounding community for many years. In December 2011, a community consultation committee, the Rutherford Air Quality Liaison Committee (RAQLC), was established by the NSW Minister for the Environment to oversee this project, with secretarial support provided by the NSW Environment Protection Authority (EPA). The project occurred in four stages: an overview of odour issues and complaints along with suggested directions for detailed analysis; a detailed assessment of odour emissions from the eight major sources in the R IE ; a modelling study showing the odour dispersion from the industries in comparison to the spatial distribution of complaints; and an olfactometry study verifying the major odours of residential concern. Three major odours and sources were identified: petroleum/burnt oil/petrol from an asphalt plant; canola/grainy/gassy from a vegetable oil processor; and burnt plastic/paint/ kerosene from a textile plant. The results provided information for priority action by the industries and the NSW EPA to reduce or eliminate these odours. The RAQLC is a good example of a community consultation committee with decision-making powers, working jointly with the NSW EPA to identify odour emissions and sources.

Over the last few years, Pakistani cities have undergone an extensive growth in infrastructure and car ownership. This has led to an increase in air emission sources and subsequent degradation in air quality. The Pakistani Government has taken some initiatives to minimise the impact of air pollution. However, much more needs to be done to properly assess the adverse impact of degrading air quality on the population and develop emission control strategies accordingly. This paper provides a snapshot of air pollutants such as Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2) and CO in winter months in Quetta, the capital of Balochistan province in western central Pakistan. The results suggest that nearly all the compounds of interest show diurnal variation, although the magnitude of the diurnal cycle differs on different days for different prevailing wind directions. The highest pollution levels occur during the morning rush hour and afternoon rush hour period and suggest that the monitoring site is impacted by anthropogenic emission sources (i.e. heavy traffic flow).
