Thousands of spills at US oil and gas fracking sites.

February 22, 2017

A study carried out by the US Environment Protection Agency on fracking in eight states between 2006 and 2012 concluded that 457 spills had occurred. But this new study, while limited to just four states with adequate data, suggests the level of spills is much higher. The researchers found 6,648 spills between 2005 and 2014. BBC.

Estimating deaths attributable to airborne particles: sensitivity of the results to different exposure assessment approaches.

February 22, 2017

A reduction in particle concentrations could have produced significant health benefits in the region. This general conclusion did not change when different exposure definitions were used, provided that the same exposure assessment approach was used for both effect and impact estimations. Caution is therefore recommended when using effect estimates from the literature to assess health impacts of air pollution in actual contexts. Environmental Health.
