Indeed, farms have become the largest contributor to air pollution damages from PM2.5 In a new study of PM 2.5
This brief study analyses, for each individual state, the changes from 2008 to 2018 in the use of coal (one of the two most polluting energy sources) to generate electricity. The results indicate that the percentage of electricity generated from coal decreased from 2008 to 2018 in 49 states.
Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Ozone is harmful to humans at ground-level, causing pulmonary and heart disease.
A new University at Buffalo (UB) study based on levels before, during and after the Beijing Olympics has shown how air pollution affects the human body at the level of metabolites. Metabolites are small molecules that are the end products of environmental exposures, such as air pollution, and body metabolism.
Infants born to women exposed to high levels of air pollution in the week before delivery are more likely to be admitted to a newborn intensive care unit (NICU), suggests an analysis by researchers at the US National Institutes of Health (NIH). Short-term exposure to most types of air pollutants may increase the risk for NICU admission.

Despite the economic effects of the global financial crisis (GFC), carbon dioxide emissions from human activities rose 2% in 2008 to an all-time high of 1.3 between 2000 and 2008, compared with 1% per year in the 1990s. Emissions from coal are now the dominant fossil fuel emission source, surpassing 40 years of oil emission prevalence.
The US Environmental Protection Agency (EPA) has finalized the new Cross-State Air Pollution Rule (CSAPR) (also called the Transport Rule). The Cross-State Air Pollution Rule replaces and strengthens the requirements of the 2005 Clean Air Interstate Rule (CAIR), which the US Court of Appeals for the DC Circuit ordered EPA to revise in 2008.
The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids. Generation mix of the six interprovincial power grids in 2008. and NO x emissions. Credit: ACS, Huo et al.
Updated emission estimates for the EU for 2010 show just 14 Member States expect to meet their respective 2010 air pollutant limits set under the EU National Emission Ceilings Directive (NEC Directive), according to the European Environment Agency (EEA). The progress toward meeting ceilings for the other pollutants remains largely on track.

Despite marginal improvements in utilization efficiency, coal continues to be the most polluting fossil fuel. million barrels per day (Mbpd) in 2008, up from 1.0 in 2008 to reach 7.6 Oil production reached 10.7
They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. The second engine was a Ford 2008 6.4 —Chin et al.
Data collected during a major 2010 state-federal atmospheric research project show that the first-in-the-nation regulation requiring ocean-going vessels to use clean fuel when near the California coast has been extremely effective in reducing sulfur dioxide pollution from ships, according to the California Air Resources Board (ARB).
This brief study analyzes, for each individual state, the changes from 2018 to 2020 in the use of coal (one of the two most polluting energy sources) to generate electricity. This study is an update of a study that examined the changes from 2008 to 2018. Therefore, the data for 2008 are included here as well. from coal.

Regulatory background. Background Data.
New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23% the number of days of light rain in the eastern half of the country. While the light rains have diminished, pollution has increased dramatically in China in the last half of the 20 th century.

The decrease in full-scale IQ score among the more exposed children is similar to that seen with low-level lead exposure. Pediatrics.
Shore Power is a shore-to-ship connection that provides electrical power to the ship, thereby significantly reducing diesel and other air pollutant emissions from ships while they are at berth. In 2008, the California Air Resources Board adopted a regulation to require reductions of air pollutants from ocean-going vessels.

These new compounds were not previously known to exist, and raise additional concerns about the health impacts of heavily-polluted urban air or dietary exposure. PAHs are one of the types of pollutants found on particulate matter in air pollution that are of special concern. Staci Simonich.
Results from a new study by researchers at the University of California Irvine support a growing body of scientific literature indicating that sensitive populations, including children, certain ethnic groups and people of lower socioeconomic status, are more vulnerable to the effects of high exposures to traffic-related air pollution.
A key objective for international shipping under the IMO’s mandate is to reduce greenhouse gas emissions by half compared to 2008 levels. Our new concept vessel can dramatically reduce air pollutant emissions, as well as noise and vibration and maintenance and repair costs, by replacing an internal combustion engine with fuel cells.

With indoor air pollution killing 1.6 Shown are the tipping elements [large-scale components of the Earth’s system] and the temperature threshold range that initiates the tipping. From Molina et al. Ramanathan. Tropospheric ozone. It also lowers crop yields.
pollution in the state. is especially burdensome in California and accounts for the greatest percentage of health impacts attributable to air pollution. MISR has other applications, including the ability to distinguish between different types of particle pollution. to predict PM 2.5 Most monitors do not track individual PM 2.5
Research has shown that more than three quarters of total air pollution comes from vehicle carbon monoxide and hydrocarbon emissions in large cities including Beijing, Shanghai and Guangzhou. Beijing municipal government raised vehicle emission standards four times from standard I in 1999 to Standard IV in 2008.
The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.
The San Joaquin Valley Air Pollution Control District is made up of eight counties in California’s Central Valley: San Joaquin,Stanislaus, Merced, Madera, Fresno, Kings, Tulare and the San Joaquin Valley Air Basin portion of Kern.
In 2008, the 8-hour standard was lowered to 0.075 ppm. These new SIPs demonstrate that, by 2024, pollution will be reduced to the level needed to attain the 1997 8-hour ozone standard of 0.08 In the San Joaquin Valley, district rules will reduce pollution from open burning, boilers, composting, and livestock operations.
