Published Extreme UV laser shows generation of atmospheric pollutant
(via sciencedaily.com) Scientists show that under laboratory conditions, ultraviolet light reacts with nitrophenol to produce smog-generating nitrous acid.
Published Immense hydrocarbon cycle discovered in world's ocean
(via sciencedaily.com) Hydrocarbons and petroleum are almost synonymous in environmental science. After all, oil reserves account for nearly all the hydrocarbons we encounter. But the few hydrocarbons that trace their origin to biological sources may play a larger ecological role than scientists originally suspected.
Published Failed storage tanks pose atmospheric risks during disasters
(via sciencedaily.com) Engineers model the hypothetical threats from toxins released when above-ground storage tanks fail during a storm. Using data from hurricanes Ike and Harvey and from the Houston Ship Channel, they illustrate potential atmospheric pollutants during and after a disaster.
Published Researchers trace geologic origins of Gulf of Mexico 'super basin' success
(via sciencedaily.com) The Gulf of Mexico holds huge untapped offshore oil deposits that could help power the U.S. for decades. According to researchers, the basin's vast oil and gas reserves are the result of a remarkable geologic past. Only a fraction of the oil has been extracted and much remains buried beneath ancient salt layers, just recently illuminated by modern seismic imaging.
Published Early COVID-19 lockdown in Delhi had less impact on urban air quality than first believed
(via sciencedaily.com) The first COVID-19 lockdowns led to significant changes in urban air pollution levels around the world, but the changes were smaller than expected, a new study reveals.
Published Potentially damaging surface ozone levels rose in lockdown, UK study finds
(via sciencedaily.com) A new study finds that less traffic on the roads during the first lockdown led to a reduction in air pollution but may have caused potentially damaging surface ozone levels to rise.
Published Scientists warn of likely massive oil spill endangering the Red Sea, region's health
(via sciencedaily.com) A new study is calling for action to remove the oil from a decaying and inactive tanker in the Red Sea that holds approximately one million barrels of oil - four times the amount of oil contained in the Exxon Valdez, the tanker that had a disastrous environmental oil spill in 1989 - before its current seepage turns into a massive oil spill into the sea.
Published Mass extinctions of land-dwelling animals occur in 27-million-year cycle
(via sciencedaily.com) Original source Mass extinctions of land-dwelling animals--including amphibians, reptiles, mammals, and birds -- follow a cycle of about 27 million years, coinciding with previously reported mass extinctions of ocean life, according to a new analysis.
Published Study connects diabetes, air pollution to interstitial lung disease
(via sciencedaily.com) Original source People with pre-diabetes or diabetes who live in ozone-polluted areas may have an increased risk for an irreversible disease with a high mortality rate. These findings are especially important today in the midst of the COVID-19 pandemic, where there is a heightened concern for the convergence of health effects from air pollution and SARS-CoV-2 in susceptible populations.
Published Inexpensive, non-toxic nanofluid could be a game-changer for oil recovery
(via sciencedaily.com) Researchers have demonstrated that an inexpensive and non-toxic nanofluid can be used to efficiently recover even heavy oil with high viscosity from reservoirs.
Published Study first to show tiger sharks' travels and desired hangouts in the Gulf of Mexico
(via sciencedaily.com) From 2010 to 2018, scientists tagged 56 tiger sharks of varying life stages to track their movements via satellite. Movement patterns varied by life stage, sex, and season. Some of their core habitats overlapped with locations designated by NOAA as Habitat Areas of Particular Concern and also were found near 2,504 oil and gas platforms. Findings may help inform studies into potential climate change, oil spills, and other environmental impacts on tiger shark movement in the Gulf of Mexico.
Published Children exposed to Deepwater Horizon oil spill suffered physical, mental health effects
(via sciencedaily.com) A recent study has found that the Deepwater Horizon disaster was harmful to the mental and physical health of children in the area.
Published Sun and rain transform asphalt binder into potentially toxic compounds
(via sciencedaily.com) Chemists show that asphalt binder, when exposed to sun and water, leaches thousands of potentially toxic compounds into the environment.
Published Oil spill clean-up gets doggone hairy
(via sciencedaily.com) Researchers have found that dog fur and human hair products -- recycled from salon wastes and dog groomers -- can be just as good as synthetic fabrics at cleaning up crude oil spills on hard land surfaces like highway roads, pavement, and sealed concrete floors.
Published Oil forecasting technique adapted for spreadsheets may cut shale operator costs
(via sciencedaily.com) Porous rock containing oil and natural gas are buried so deep inside the earth that shale operators rely on complex models of the underground environment to estimate fossil fuel recovery. These simulations are notoriously complex, requiring highly-skilled operators to run them. These factors indirectly impact the cost of shale oil production and ultimately, how much consumers pay for their fuel.
Published Protecting natural forest in oil palm plantations crucial for conservation
(via sciencedaily.com) A study has found that patches of protected forest on oil palm plantations play an important role in helping to conserve endangered species including hornbill birds and dipterocarp trees.
Published Smart sponge could clean up oil spills
(via sciencedaily.com) Researchers have developed a highly porous smart sponge that selectively soaks up oil in water. It can absorb more than 30 times its weight and be reused many dozens of times.
Published Unknown submarine landslides discovered in Gulf of Mexico
(via sciencedaily.com) A researcher has used new detection methods to identify 85 previously unknown submarine landslides that occurred in the Gulf of Mexico between 2008 and 2015, leading to questions about the stability of oil rigs and other structures, such as pipelines built in the region.
Published Window to another world: Life is bubbling up to seafloor with petroleum from deep below
(via sciencedaily.com) Microbial life is bubbling up to the ocean floor along with fluids from deeply buried petroleum reservoirs, reports a team of scientists.
Published Long-term consequences of coastal development as bad as an oil spill on coral reefs
(via sciencedaily.com) Oil pollution is known to cause lethal and sublethal responses on coral communities in the short-term, but its long-term effects have not been widely studied. The Bahia Las Minas oil spill, which contaminated about 40 square kilometers (about 15 square miles) near the Smithsonian's Galeta Point Marine Laboratory in Colon and became the largest recorded near coastal habitats in Panama, served as an opportunity to understand how coral reefs in tropical ecosystems recover from acute contamination over time.
