Poor air and water quality adversely affects human health and environmental monitoring is now carried out in cities across the world in order to improve the health of populations and to meet regulatory requirements. However, our current knowledge of the air and water quality where we live, work and play, is limited due to the fact that existing monitoring technologies are often large and expensive to operate or highly labour-intensive. New methods such as lab-on-a-chip technologies, wireless sensor networks and robotics offer the potential to generate real-time and extremely local, even personal, environmental exposure date. In the future, these technologies could become the platform which will drive our understanding of environmental quality and its impact on health. In this presentation, Alistair Boxall will provide an overview of work being done at York to develop novel approaches to detect and monitor pollutants in city environments. He will describe the YorkSense project which is instrumenting the city of York with a variety of new technologies in order to generate an unprecedented dataset on environmental quality in the city from 2015-2016.
