More than 80 percent of all waste from Pennsylvania's oil and gas drilling operations stays inside the state, according to a new study that tracks the disposal locations of liquid and solid waste from these operations across 26 years. Numerous human health hazards have been associated with waste from oil and gas extraction, including potential exposure to compounds known to cause cancer.
Nine years ago tomorrow -- April 20, 2010 -- crude oil began leaking from the Deepwater Horizon drilling rig into the Gulf of Mexico in what turned out to be the largest marine oil spill in history. A long-term study suggests the oil is still affecting the salt marshes of the Gulf Coast, and reveals the key role that marsh grasses play in the overall recovery of these important coastal wetlands.
The American Bumblebee - a species once more commonly seen buzzing around Southern Ontario - is critically endangered, according to a new study led by York University. The finding, published in Journal of Insect Conservation, found the native North American species, Bombus pensylvanicus, is facing imminent extinction from Canada, considered the highest and most at-risk classification before extinction.
Gaming and virtual reality could bridge the gap between urban societies and nature, thereby paving the way to insect conservation by the means of education and participation. This is what an interdisciplinary team at Florida International University strive to achieve by developing a virtual reality game (desktop version also available) dedicated to insect and plant species. Focused on imperiled butterflies, their innovative idea: Butterfly World 1.0, is described in the open-access journal Rethinking Ecology.
Researchers from the UK and Spain have identified an eco-friendly solid that could replace the inefficient and polluting gases used in most refrigerators and air conditioners.
A study led by AN Zhisheng from the Institute of Earth Environment (IEE), Chinese Academy of Sciences, reviews and synthesizes recent advances in the causes and formation mechanisms of severe haze pollution in northern China.
New research reveals how soil bacteria build the only known enzyme for the destruction of the potent global warming and ozone-depleting gas nitrous oxide. Alongside carbon dioxide (CO2) and methane, the greenhouse gas nitrous oxide (N2O), commonly known as 'laughing gas', is now a cause for great concern, and there is much international focus on reducing emissions. It is hoped that the findings will help pave the way for strategies to mitigate the damaging effects of N2O.
Contamination of rice with arsenic is a major problem in some regions of the world with high rice consumption. Now, researchers reporting in the ACS journal Environmental Science & Technology have found a way to reduce inorganic arsenic in rice by modifying processing methods at traditional, small-scale parboiling plants in Bangladesh. The new method has the added benefit of increasing the calcium content of rice, the researchers say.
In 2015, a fluorosurfactant known by the trade name 'GenX' made headlines when researchers discovered it and related compounds in the Cape Fear River of North Carolina, a source of drinking water for many residents of the area. Now, researchers report in ACS' journal Environmental Science & Technology that they have detected the same per- and polyfluoroalkyl substances (PFASs) in the river, as well as some new ones, but their overall levels are decreasing.
Oxidants found within living organisms are byproducts of metabolism and are essential to wound-healing and immunity. However, when their concentrations become too high, inflammation and tissue damage can occur. University of Illinois engineers have developed and tested a new drug-delivery system that senses high oxidant levels and responds by administering just the right amount of antioxidant to restore this delicate balance.
