In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. Over the course of five years, PM 2.5
The World Health Organization now estimates that in 2012 around 7 million people died—one in eight (12.5%) of total global deaths—as a result of air pollution exposure. million deaths linked to indoor air pollution and 2.6 million deaths related to outdoor air pollution—5.9 million deaths in total.
While coal use causes warming through emission of heat-trapping carbon dioxide, it also releases comparatively large amounts of sulfates and other particles that, although detrimental to the environment, cool the planet by blocking incoming sunlight. —Tom Wigley. Methane is an especially potent greenhouse gas. degree Celsius).
Air pollution in India resulted 1.67 million deaths in 2019—the largest pollution-related death toll in any country in the world—and also accounted for $36.8 The 2019 death toll attributed to air pollution in India accounted for 17.8% Pollution takes an enormous human toll in India. It is causing 1.67
Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The findings associated ozone exposure with markers of platelet activation and increased blood pressure.
This year’s report includes the latest results on air pollution exposure and its health burden around the world based on the 2017 GBD (Global Burden of Disease) study. Among the findings of the report is that current levels of air pollution levels have reduced life expectancy by 1 year and 8 months (1.67 and tropospheric ozone.
1,000 to 21,000) deaths due to changes in ozone concentrations. 900 to 11,000) ozone-related early deaths per year. 300 to 4,000) ozone-related premature mortalities per year. 2000 (90% CI: 0–4,000) early deaths from ozone, according to the study. 53,000 (90% CI: 24,000–95,000) PM 2.5 related premature deaths and ?5,000
The proposed Transport Rule sets in place a new approach that can and will be applied again as further pollution reductions are needed to help areas meet air quality health standards, EPA says. This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines.
Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and ventilation air from coal mines. Replacing coal by coal briquettes in cooking and heating stoves.
Ozonepollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise.
The European Community’s air pollutant emission inventory report released by the European Environment Agency finds that in 2007, sulphur oxides (SO x ) emissions were down by 72 % from 1990 levels. EU-27 emissions of all four pollutants were lower in 2007 than in 2006.
Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said.
Denver represents an interesting case study for exploring potential PHEV impacts because it violates the federal air quality standard for ozone and because several large EGUs [electricity generating units] are located in or near the urbanized area. Ozone concentration increases were modeled for small areas near central Denver.
This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. … solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e., —Schnell et al.
The EPA has dismissed two panels of outside scientists that advised the agency on particulate matter and ground-level ozone, which have been linked to smog and respiratory problems.
A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts per billion (ppb) of ozone; the current US Environmental Protection Agency (EPA) 8-hour average standard is 75 ppb.
Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming.
Air pollution is the leading environmental cause of death worldwide according to the State of Global Air 2018 , the annual report and interactive website published by the Health Effects Institute (HEI). Population-weighted seasonal average ozone concentrations in 2016. coal, wood, and dung) for cooking and heating.
New NASA satellite images released this week demonstrate the reduction of air pollution across the US. After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide.
As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. —Drew Shindell.
Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b].
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). The researchers included a sixth pollutant, ammonia (NH 3 ).
This partnership was led by EPA’s Design for the Environment (DfE) Program, in the Office of Pollution Prevention and Toxics, and the National Risk Management Research Laboratory, in EPA’s Office of Research and Development. 2 Occupational cancer hazard impact was scaled to 50% in this figure because of the wide range across stages.
The draft promotes development of carbon capture and sequestration (CCS) technologies to establish a continuing place for coal in the US energy mix. The draft includes a CCS early demonstration program, incentives for the wide-scale commercial deployment of CCS, and performance standards for new coal-fired power plants.
Inventorying criteria air pollutants showed that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 All components appear in the order they are shown in the legend.). Chester and Horvath (2009).

While it’s obvious that the internal combustion engine vehicles are polluting the air outside the buses, what you may not know is that numerous studies show that the pollution from the burning diesel regularly makes its way into the buses. The more vehicles that switch to running on electricity, the better.
Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?
In this celebration, we acknowledge the future of green technology is not only healthier for the planet and its residents, but more high-tech than more archaic, higher polluting options. These green tech solutions suitable replacements for pollution-creating solutions. Earth Day and Green Tech. than gas-fueled vehicles. .

Quantifies the production of pollutantozone (? to ozone layer), the results of the reaction of sunlight on NO x and volatile organic compounds. water, and non-renewable energies (crude oil, coal.) Quantifies the quantity of energy (crude oil, coal.)
New research shows that household (indoor) and outdoor air pollution contribute to more than 5.5 In the context of the Global Burden of Disease 2013 study ( earlier post ), researchers from Canada, the United States, China and India quantified air pollution levels and attributable health impacts for 188 countries for the period 1990-2013.
A new report from the European Environment Agency (EEA) warns that the health of Europe’s most vulnerable citizens remains disproportionately affected by environmental hazards such as air and noise pollution and extreme temperatures, especially in Europe’s eastern and southern regions, despite overall improvements in Europe’s environmental quality.
Additionally, the study found that the population-weighted mean concentrations of ozone increased globally by 8.9% The Global Burden of Disease (GBD) 2013 provided important estimates of the global health impacts attributable to ambient air pollution. An additional 217,000 deaths were attributable to long-term ozone exposure.
Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems.
I mean, when the electricity it uses is produces, pollution still happens, just not "right from your car"? That being said, even a car that derives its energy from coal power plants would be far more clean. excluding coal power in china. Low Ranked richii @ Apr 19th 2009 4:29PM for some reason this makes me think of the future.
Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). The next round of UN climate negotiations begins in Cancun today.
