What is the research trying to show?
The research is to describe a possible link between the geology of a water basin and the incidence of cardiovascular disease.
Is there any evidence that geology has an impact on health?
Substantial body of work in this area. The Inst. Of Geology publishes a journal, during the 1960s there was much study and there is a new interest in the area.
Why Australia?
The geology of Australia is old (Palaeocene and Miocene) and therefore has a great number of exploitable minerals, but perhaps not those in the correct concentration for life. The incidence of Chronic Heart Disease in the Uk with a younger geology in many places is 1.1%, in Australia it is believed to be 2.3% of adults over 35 years.
What data is needed?
Postcodes have been linked to the drainage basin in which they are located. The geology has also been liked to basin and postcode.

What does the research show?
The intricate relationship between geological elements and human health has been a subject of study since ancient times, with early contributions from Greek scholars like Hippocrates and Aristotle. This field, now known as Medical Geology, examines the impact of various geological materials on health, including elements such as lead, radon gas, and asbestos. Human exposure to potentially harmful elements occurs through multiple pathways, including volcanic activity and the natural composition of rocks, which are the source of all elements on Earth. Essential minerals for human health, such as sodium, potassium, calcium, and magnesium, originate from geological sources, and their deficiency or excess can lead to significant health issues.
This paper explores the geographical implications of Medical Geology, particularly focusing on the correlation between the geology of Australia’s water catchment areas and the incidence of cardiovascular disease (CVD). Australia exhibits a higher prevalence of CVD compared to other countries, with notable regional variations potentially linked to geological factors. The study utilizes data from the National Health Survey, geological datasets, and prescription records to analyse the relationship between geological periods and health outcomes.
Key findings indicate that regions with different geological compositions exhibit varying rates of CVD, suggesting a significant influence of local geology on health. For instance, areas with higher magnesium levels in drinking water show lower incidences of cardiovascular diseases. The study also highlights the importance of considering local geological conditions when planning new settlements or expanding existing ones, as these factors can profoundly impact public health.
The methodology involves integrating data on water catchments, geological regions, and health statistics, standardized to a common geographic framework. The analysis reveals strong correlations between geological characteristics and health outcomes, emphasizing the need for a spatially aware approach in Medical Geology. This research contributes to a deeper understanding of how geological factors influence health and underscores the importance of incorporating geological considerations into public health strategies.
