Sentinel satellite exposes sulphur dioxide pollution

Sentinel satellite exposes sulphur dioxide pollution

Science
What must it be like to live in the Siberian town of Norilsk on a "bad air day"? They say the local smelting industry produces 1% of all the sulphur dioxide (SO₂) going into the air globally, something close to two million tonnes a year. SO₂ is particularly unpleasant if breathed in; but it also washes out of the sky as "acid rain", damaging plant-life and denuding the quality of water in streams and rivers. The extent of Norilsk's pollution problem is captured in remarkable new maps from Europe's Sentinel-5P satellite. The spacecraft was put up last year to track the gases responsible for dirty air - with SO₂ being one of the prime culprits. Assembled in the UK and carrying the Dutch-led Tropomi instrument, S5P...

Pollution hits fungi that nourish trees – study

Science
Scientists are warning that pollution could be starving Europe's trees of vital nutrients by damaging essential fungi.The fungi live on the roots of trees, supplying them with minerals and water.Current pollution limits may not be strict enough to protect the forest fungi, say researchers.Signs of tree malnutrition, such as discoloured or missing leaves, have been seen across Europe's forests.Loss of fungi may be a factor, according to the study, published in the journal, Nature."If we care about the condition of our forests - what shape they're in - we can't just look above (the ground)," Dr Martin Bidartondo, from the department of life sciences at Imperial College London and Royal Botanic Gardens, Kew, told BBC News."We need to look below - we need to ...
Bardem wants more action on plastic pollution

Bardem wants more action on plastic pollution

Entertainment
Actor Javier Bardem has told Sky News in an exclusive interview that more companies should follow its Ocean Rescue campaign to try to cut plastic pollution in the sea. The Spanish star, best known for his roles in the Bond movie Skyfall and No Country For Old Men, was speaking from Port de Blanes in the north of Spain where he had been out with early morning fishermen who had started sorting the plastic collected in their nets for recycling."I was there for an hour and we took out so much plastic, only in one hour," he said."It was outstanding to see how much dirt you can find here with a net."

Science Says: Amount of straws, plastic pollution is huge

Science Says: Amount of straws, plastic pollution is huge

Technology
Cities and nations are looking at banning plastic straws and stirrers in hopes of addressing the world's plastic pollution problem. The problem is so large, though, that scientists say that's not nearly enough. Australian scientists Denise Hardesty and Chris Wilcox estimate, using trash collected on U.S. coastlines during cleanups over five years, that there are nearly 7.5 million plastic straws lying around America's shorelines. They figure that means 437 million to 8.3 billion plastic straws are on the entire world's coastlines. But that huge number suddenly seems small when you look at all the plastic trash bobbing around oceans. University of Georgia environmental engineering professor Jenna Jambeck calculates that nearly 9 million tons (8 million metric tons) end up in the world's oc...

Minimal air pollution can trigger lung conditions in kids

Health
April 13 (UPI) -- Brief exposure to minuscule air pollution particles trigger acute lower respiratory infection in young children, according to research.Scientists from Intermountain Healthcare in Utah, Brigham Young University and the University of Utah studied exposure to PM2.5, pollution-causing particles that measure about 3 percent of the diameter of a human hair. Their findings were published Friday in the American Journal of Respiratory and Critical Care Medicine, an American Thoracic Society journal.The study involved 146,397 patients with acute lower respiratory infection in Utah between 1999 and 2016. The researchers said this is the largest study involving air pollution and children."The most important finding of this study is that infectious processes of respiratory disease may...
