Each year thousands of new chemicals are produced that, along with pre-existing chemicals, enter the soil, air and waterways, altering in complex ways the essential eco-systems for human and animal existence.  The impact of most chemicals on the environment and on human health is largely unknown. Research in environmental health at UQ seeks to identify the sources, and then monitor the fate and effects, of environmental contaminants.  The ultimate purpose of such research is to generate a better understanding of the risks of chemical exposure and develop prevention strategies to safeguard environmental and human health. Such work is fundamental to ensuring a future of healthy humans in a healthy environment.
