"GIS Modelling of Environmental Air Pollution to Assess and Map Its Impact on Cardiovascular Mortality – The Bangalore Case Study"

Prof. Raouf Naguib
Coventry University

Based on the premise that the environment plays a vital role in the health and well-being of populations, this Lecture presents current research being undertaken in the BIOCORE research group at Coventry University, UK. The aim is to spatially model the spread of pollutants and determine the consequent trends of cardiovascular (CVD) mortality. The research study utilises the powerful spatial processing capabilities of Graphical Information Systems (GIS) to analyse any potential associations between the hazardous pollutants SO2, NOx and PM10 and rates of CVD deaths, with particular emphasis on the sprawling city of Bangalore, India. CVD mortality rates are classified as a result of Rheumatic Heart Disease, Ischemic Heart Disease and Stroke, among others. Due to the limited number of air quality monitoring stations in Bangalore, geostatistical analysts' interpolation techniques are employed to model a continuous pollution surface for the years 2010-2012 on a zonal level, highlighting the pollution hotspots. Spatial Regression is employed to understand and predict cardiovascular mortality outcomes from air pollution exposure, while controlling for other confounding factors. Spatial autocorrelation tools are used to assess if the pattern is clustered, random or dispersed and to summarise the trend of pollution and CVD mortality over space and time.

Various epidemiological studies provide evidence of an association between cardiovascular health and air pollution. Unfortunately, many developing countries in Asia and South East Asia significantly lack research in this area and there is an urgent need for improved information and knowledge on the deleterious effects of pollutants and their effects on cardiovascular health. The outcome of our study, based on Bangalore, India, as a representative case study, will result in the development of an information tool mapping the level of pollutants and geographical patterns of CVD. An intervention framework based on a GIS infrastructure will be proposed to address the issues and challenges in Bangalore and adopt a strategy to raise awareness among policy makers and the public on cardiovascular health as a consequence of environmental anomalies.
