Concerns over chemical treatment of reclaimed fracking fluid

The study analysed water samples from shale gas wells in Marcellus (Pennsylvania), Eagle Ford (Texas), and Barnett (New Mexico) © Michael J Mullen Scranton Times-Tribune/AP/Press Association Images

Estimates suggest that in the next 50 years, over one trillion gallons of water will be used in shale gas extraction but research from scientists in the US suggests that environmentally detrimental compounds are being created when this fluid is recycled.

Shale gas is found in rock formations kilometres underground. Hydraulic fracturing, also known as fracking, facilitates the release of this energy dense fuel in a cost-effective and timely manner. Water, sand and a combination of other additives are pumped into the ground at high pressure, breaking the shale formations apart, allowing the gas to migrate to the surface where it can be collected.

Fireworks and the spread of particulate matter

A detailed study on the spatiotemporal distribution of atmospheric pollutants arising from the wide scale use of fireworks has been carried out by scientists in China, with a view to highlighting related environmental and health concerns.

Fireworks and firecrackers are used extensively across the globe in all manner of celebrations, though few match the sheer scale of Chinese New Year. They generate a variety of contaminants, including gasses such as carbon monoxide, sulphur dioxide and nitrogen oxide, in addition to aerosols of microparticles known as particulate matter.
