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 …

Grass invasion in urban lowland fynbos fragments on the Cape Flats : does nutrient addition play a role?
… world that nutrient additions from deposition of airborne pollutants were responsible for increased dominance of grass in natural ecosystems led us to test whether this was the case on the Cape flats. Phytometers were used to gauge the favourability for growth of soils from urban sites compared to …

Examining the Modifiable Areal Unit Problem: Associations Between Surface Mining and Birth Outcomes in Central Appalachia at Multiple Spatial Scales
… used to quantify the influence area of potential airborne pollutants from surface mining activity, were built using HYSPLIT4. The frequency values of each airshed that intersected each geocoded birth record were summed. These cumulative frequency airshed values were then aggregated. Finally, we …

Modification by sex and atopy of the effect of chemical air pollutions and biological air pollutants including pollen and fungal spores on children respiratory health in the Western Cape, Cape South Africa
… middle-income countries, together exposure to airborne pollutants and allergens contribute to this disease burden. A cross-sectional study that recruited 590 school children residing in four informal settlements in the Western Cape province was conducted to assess the role of sex and atopic …

Atmospheric dispersion modelling of particulate and gaseous pollutants affecting the trans-Manche region
… concerned with outdoor exposure to atmospheric pollutants and aims to identify pollution sources using dispersion modelling with the assistance of ground level measurements from British, French and other monitoring stations and remote sensing technology. Lagrangian Particle Dispersion (LPD) …

Advancements in concrete material sustainability : supplementary cementitious material development and pollutant interaction
… dissertation investigate the interaction between airborne pollutants and the cement based materials containing SCMs. The use of SCMs in render and concrete systems resulted in different pollutant uptake and exhalation behavior, relative to non-SCM control systems. For pollutant uptake, render …

ESSAYS ON INTERNATIONAL TRADE AND THE ENVIRONMENT
… I study the impact of international trade on airborne pollutants, including the change in emissions and concentration as well as their welfare consequences. In the first chapter, I suggest the intermediate import channel as a new perspective to understand the linkage between international …
