A study has found long-term impacts of the 2010 Deepwater Horizon oil spill in the northern Gulf of Mexico on bottlenose dolphins' immune function.

Global emissions of a potent substance notorious for depleting the Earth's ozone layer -- the protective barrier which absorbs the Sun's harmful UV rays -- have fallen rapidly and are now back on the decline, according to new research.

Chemists have helped discover that iodic acids can rapidly form aerosol particles in the atmosphere, giving scientists more knowledge of how iodine emissions can contribute to cloud formation and climate change.

Ozone is a problematic air pollutant that causes serious health problems. A newly developed material not only quickly and selectively indicates the presence of ozone, but also simultaneously renders the gas harmless. The porous '2-in-one systems' also function reliably in very humid air.

Scientists show that under laboratory conditions, ultraviolet light reacts with nitrophenol to produce smog-generating nitrous acid.

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.

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.

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.

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.

     (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.

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.

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.

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.

Researchers have demonstrated that an inexpensive and non-toxic nanofluid can be used to efficiently recover even heavy oil with high viscosity from reservoirs.

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.

A recent study has found that the Deepwater Horizon disaster was harmful to the mental and physical health of children in the area.

Chemists show that asphalt binder, when exposed to sun and water, leaches thousands of potentially toxic compounds into the environment.

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.

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.

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.
