Over the course of six years (2006–2011), equivalent black carbon (eqBC), coarse aerosol mass (PM 1–10), and surface ozone (O 3), observed during the monsoon onset period at the Nepal Climate Observatory–Pyramid WMO/GAW Global Station (NCO-P, 5079 m a.s.l.), were analyzed to investigate events characterized by a significant increase in …
BEIJING -- Only nine of 161 Chinese cities reached the new -- and stricter -- air quality monitoring standards in the first half of this year, according to the Ministry of Environmental Protection (MEP). Zhoushan, Shenzhen, Zhuhai, Zhanjiang, Yunfu, Beihai, Sanya and Lhasa are the cities which reached the standard, …
Climate change could pose an even greater threat to global food production than previously thought, according to new research. Rising temperatures will not only damage heat-sensitive crops – they’ll also increase toxic air pollution, which will harm crops even further. The study, out this week in the journal Nature Climate …
Ozone pollution, which worsens breathing problems and causes air quality warnings, may compound global warming's damage to the world's food crops, according to a new study. Ground-level ozone, formed mainly from pollutants emitted by burning fossil fuels for cars, industry and power plants, increases as temperatures rise. That's why air …
Trees remove air pollution by the interception of particulate matter on plant surfaces and the absorption of gaseous pollutants through the leaf stomata. However, the magnitude and value of the effects of trees and forests on air quality and human health across the United States remains unknown. Computer simulations with …
Future food production is highly vulnerable to both climate change and air pollution with implications for global food security. Climate change adaptation and ozone regulation have been identified as important strategies to safeguard food production5,6, but little is known about how climate and ozone pollution interact to affect agriculture, nor …
Hong Kong’s air pollution reached the “serious” level today, the highest since June 14, as an approaching typhoon leads to smog, according to a government website. The pollution level was higher than normal as of 4 p.m., with the Air Quality Health Index reaching the maximum level of 10-plus at …
China's air quality improved slightly in the first half of 2014 compared with the same period in 2013, but aggravated ozone pollution became a prominent problem across the country, according to Environmental Protection Ministry figures released on Monday. In 74 major cities, air quality was good 60.3 percent of the …
The mission of Aura, which is Latin for breeze, centers on obtaining measurements of ozone, aerosols and key gases throughout the atmosphere. And after one decade in space, the satellite has provided vital data about the cause, concentrations and impact of major air pollutants. One instrument on the satellite, built …
Epidemiological studies have reported associations between air pollution exposure and increases in cardiovascular morbidity and mortality. Exposure to air pollutants can influence cardiac autonomic tone and reduce heart rate variability, and may increase the risk of cardiac arrhythmias, particularly in susceptible patient groups.
Poor air quality causes an estimated 2.6–4.4 million premature deaths per year. Hazardous conditions form when meteorological components allow the accumulation of pollutants in the near-surface atmosphere. Global-warming-driven changes to atmospheric circulation and the hydrological cycle are expected to alter the meteorological components that control pollutant build-up and dispersal, but …
Some motorcyclists in Zhengzhou, capital of Henan province, wear masks on Wednesday for protection from the smog. The air was heavily polluted in the city. Li Bo / Xinhua Air quality in May around the country was slightly worse than it was the same period last year, with air quality …
5921–5941One seventh of the world's population lives in the Indo-Gangetic Plain (IGP) and the fertile region sustains agricultural food crop production for much of South Asia, yet it remains one the most under-studied regions of the world in terms of atmospheric composition and chemistry. In particular, the emissions and chemistry …
Before the sprawling Texas city of Houston and its suburbs were built, a dense forest naturally purified the coastal air along a stretch of the Gulf Coast that grew thick with pecan, ash, live oak and hackberry trees. It was the kind of pristine woodland that was mostly wiped out …
The heat has been unbearable and worse news follows. The summer pollution curve has taken an ugly turn as ground-level ozone, a highly reactive and harmful gas, has far exceeded the permissible limit, a report released by the Centre for Science and Environment (CSE) on Monday said. “With heat wave …
Just a few hours of exposure to it can trigger serious health problems, especially among those who are already suffering from respiratory and asthmatic problems As the intense heat wave conditions continue unabated, Delhi has witnessed significant ozone build-up this summer. The Centre for Science and Environment (CSE) study based …
Rising NOx levels and volatile gases in the air, primarily from vehicles, form the recipe for ozone finds this analysis by Centre for Science and Environment (CSE). Read this CSE analysis and find more in this package. Summer pollution curve takes an ugly turn as ground-level ozone, a highly reactive …
Short-term exposure to air pollution could increase a person's risk of irregular heart beat or blood clots in the lung, a new study has suggested. But researchers found "no clear evidence" for effects of short-term pollution on a certain type of heart attack or stroke. The authors from the London …
Most major Chinese cities continue to suffer heavy air pollution, but cleanup efforts are showing signs of progress, the country's environmental watchdog said on Wednesday. Only three out of 74 cities that adopted revised air quality standards made the mark last year, Li Ganjie, vice-minister of environmental protection, said during …
EPA released the Clean Power Plan, which contains proposed guidelines for reducing carbon pollution from existing power plants and from modified or reconstructed plants. The proposal aims to cut carbon pollution from the power sector by 30% and cut pollution from particulates, nitrous oxides, and sulphur dioxide by 25% by …
