Economics of air pollution: policy, mortality concentration-response, and increasing marginal benefits of abatement
This dissertation examines the economics of air pollution in three essays. The first two essays consider the implications of the possibility of increasing marginal benefits to pollution abatement. The third essay integrates a new model of air dispersion with an economic model to estimate the …

Predicting hydrocarbon nuisance odours from petroleum storage tank emissions
… nearest resident) were reviewed; and the air dispersion of two odourants, n-butane and hydrogen sulphide, were modelled under three distinct weather scenarios. The study found that operations managers could not employ the developed research procedure to predict hydrocarbon nuisance odours …

Community-based evaluation of the air toxic provisions of title III of the 1990 clean air act amendments : risks, costs and benefits
Hazardous air pollutants (HAPs) are those pollutants that are known or suspected to cause cancer, serious health effects, or adverse environmental effects. People exposed to HAPs at sufficient concentrations and durations may have an increased risk of getting cancer or experiencing other health …

Monitoring and modelling diurnal and seasonal odour and gas emission profiles for swine grower/finisher rooms
… gas problems generated by livestock facilities, air dispersion models have been used to determine reasonable science-based setback distances between the livestock operations and the neighbouring residences. However, none of the existing models consider diurnal, seasonal and climate variations of …

Development and testing of a methodology for attributing sources of airborne pollutants to their receptors
Identification of airborne pollutant sources and estimation of source contributions to air quality ‘hot spots’ are very important in ambient air quality management. Social, economical, political and legal constraints on air quality management demand a convenient and accurate method for attributing …

Detection and Characterisation of Airborne Carcinogenic Erionite Fibres in New Zealand Roadside Environments Using a Novel Integrated Methodology
Geogenic airborne dust is a common phenomenon in both urban construction zones and rural roadside environments, particularly where sediment layers are exposed and disturbed. In regions with volcaniclastic geology, such dust may contain naturally occurring carcinogenic minerals, including fibrous …

Modeling risks associated with water reuse in agriculture
According to the World Resources Institute, as of 2019, there are 68 countries experiencing at least medium-high water stress, with 17 experiencing extremely high water stress (Hofste, Reig & Schleifer, 2019). This is dire news, and any solution must balance the rate of human water consumption with …
