The air we breathe, the water we drink, and the soil beneath our feet may be quietly contributing to chronic disease. This centre brings together epidemiologists, toxicologists, and statisticians to untangle how everyday environmental pollutants—from industrial emissions to agricultural chemicals—damage human health over a lifetime. The problem is that we know pollutants are linked to low birth weight, heart and lung problems, and cancers, but we lack the integrated science to prove exactly how they cause harm. Current research often studies one pollutant or one disease in isolation, missing the real-world complexity of chemical mixtures and long-term exposure. If this work succeeds, it will provide the hard evidence needed to shape environmental health policy. Regulators could set safer limits for air pollution, identify the most dangerous industrial sources, and prioritise clean-up of contaminated land. The centre also trains the next generation of researchers, ensuring the UK has the expertise to keep these systems running for decades.

There are major public and public health concerns about the effects that the environment may be having on our health. Chronic exposure to potentially toxic substances in the environment is a fact of modern life. Chemicals and other physical agents in the environment are thought to contribute, in part, to the occurrence of various childhood and chronic diseases including reproductive effects (such as low birth weight, still birth and occurrence of congenital anomalies), chest and heart problems, and several cancers. A new approach is needed which combines epidemiological studies of large groups of people with toxicological studies if we are to understand the mechanisms by which pollutants in the environment affect health. The proposed Centre, to be held jointly between Imperial College (lead institution) and King?s College London, adopts such an integrated and multidisciplinary approach. It involves leading scientists in environmental, respiratory and air pollution epidemiology, toxicology, exposure modelling, biostatistics and research on biomarkers present in blood or urine (which may indicate levels of exposure to specific polluatants and possible early biological effects). We will integrate information from both individuals and areas where people live to look at the relations between environmental exposures and health. We will combine the use of advanced geographical information systems (GIS) and statistical modelling techniques, with experimental data, analysis of biomarkers, mechanistic studies and analyses of large population cohorts. Our aims encompass both research and training. Research in the Centre and its application will include a) methods development, involving spatial and statistical modelling and environmental toxicology and mechanisms; b) investigation of priority questions in environment and health, through two integrated research themes: health effects of sources and emissions of environmental contaminants, including mixtures of chemicals from contaminated land, major industrial sources, agriculture and the water supply, and combined effects of different pollutants; and air pollution and health, including short-, medium- and long-term effects of air pollution, pollutant mixtures, and allergens on both heart and lung problems; c) improving the science base underlying the translation of this research into environmental health policy. The training programme will support an extensive programme of short courses, Masters courses, 3- and 4-year PhD studentships, and mentoring of junior and senior researchers, with the aim of fostering the next generation of researchers and research leaders in environmental health.
