Light pollution: How lockdown has darkened our skies

Light pollution: How lockdown has darkened our skies

Science
One of the positive impacts of lockdown is that there has been a big reduction in light pollution. A nationwide star count found a 10% drop in the amount of people who could only see 10 or fewer stars, an indicator of severe light pollution.Light pollution can impact human health and wildlife by disturbing biological cycles and behaviours.The BBC's Justin Rowlatt visited the Kielder Observatory in Northumberland, an area that benefits from some of the darkest skies in England, to explore the impact of less light.Let's block ads!

Wildfire smoke particles cause more lung damage than other pollution sources

Wildfire smoke particles cause more lung damage than other pollution sources

Health
March 5 (UPI) -- The fine particles in wildfire smoke are up to 10 times more harmful to human lungs than pollution from other sources, such as car exhaust, an analysis published Friday by the journal Nature Communications found. Every 10 microgram-per-cubic meter increase in particulate matter -- the hazardous microscopic particles found in dust, pollen, smoke and soot, car exhaust and industrial emissions -- led to a 1% rise in hospital admissions for breathing problems, the data showed. Advertisement Higher levels of particulate matter in wildfire smoke, however, resulted in a 1.3% to 10% increase in hospitalizations for respiratory issues. The findings are based on an analysis of air pollution from wildfires and other sources in Southern California between 1999 and 2012. The region ha...
Noise pollution ‘drowns out ocean soundscape’

Noise pollution ‘drowns out ocean soundscape’

Science
Wegner Institute Noise from shipping, construction, sonar and seismic surveys is "drowning out" the healthy ocean soundscape, scientists say. And an "overwhelming body of evidence" has revealed the harm human-made noise does to marine life. "We've degraded habitats and depleted marine species," said Prof Carlos Duarte, who led the study, said."So we've silenced the soundtrack of the healthy ocean and replaced it with the sound that we create."Atlantic discovery: 12 new species in the deepTraffic noise impairs songbirds' abilitiesWriting in the journal Science, Prof Duarte, at King Abdullah University, Saudi Arabia, and his colleagues point out that sound waves can travel thousands of miles through the ocean.

Northrop Grumman, Navy agree $406M settlement over New York pollution

Northrop Grumman, Navy agree $406M settlement over New York pollution

Business
Dec. 22 (UPI) -- New York Gov. Andrew Cuomo announced that the state has reached an agreement with Northrop Grumman and the U.S. Navy on a $ 406 million plan to clean up a plume of underground contamination caused by aerospace manufacturing on Long Island. Under the deal, the defense contractor will pay a $ 104 million settlement for environmental damages, and those funds will be used for the 30-year containment project and related efforts. Advertisement Those efforts include protection for wells and water systems in the area that have been compromised by pollution from Northrop Grumman's former manufacturing facilities in Nassau County. "It was a long fight, but it will protect the drinking water for the people on Long Island," Cuomo said Monday. Northrop Grumman had long denied or down...

British coroner lists pollution as cause of 9-year-old’s death in landmark ruling

World
Dec. 16 (UPI) -- A coroner in Britain cited air pollution as a cause of death of a 9-year-old girl who died of an asthma attack in a landmark ruling Wednesday. The Charites Asthma U.K. and the British Lung Foundation said Ella Kissi-Debrah was the first person to have air pollution listed as a cause of death on their death certificate. Advertisement Ella, who had severe asthma that caused episodes of cardiac and respiratory arrest, died in a hospital in February 2013 after experiencing cardiac arrest from which she couldn't be resuscitated, the coroner's report said. "Air pollution was a significant contributory factor to both the induction and exacerbation of her asthma," said assistant coroner Philip Barlow. Barlow added that Ella was exposed to levels of nitrogen dioxide and particula...
