We know alarming little about the environment and health impacts of fracking and a recent review, published in the Lancet, has underlined the need for urgent research.

Working with colleagues at the London School of Hygiene and Tropical Medicine, Professor Michael Depledge has considered what we know, and more importantly, what we don’t know about this controversial method of fuel extraction.

The review illustrates that despite the industry gaining momentum across the world, scientific study of the health effects of fracking is in its infancy.

Early findings suggest that this form of extraction might increase health risks compared with conventional oil and gas wells. The larger surface footprints of fracking sites, their close proximity to locations where people live, and the need to transport and store large volumes of toxic materials are all likely to pose negative consequences for health.

Research from the USA suggests that the risks of environmental contamination are present at all stages of fracking. Surface spills, leakages and the emissions from gas-processing equipment provide ample opportunity for pollutants to contaminate the air, ground and surface water.

Professor Depledge, Chair of Environment and Health at the University of Exeter, said

“With pressure increasing from industry and politicians alike, the costs and benefits of new energy options to both human health and the environment need to be assessed, and quickly.”
