Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozonepollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Smog in India. Credit: Mark Danielson/Flickr.
The US Environmental Protection Agency announced that it is proposing to find that the San Joaquin Valley, and California’s South Coast and the Southeast Desert have failed to meet the 1-hour ozone standard by their required deadlines. Children and the elderly are most impacted by ozonepollution.
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.

Population-Weighted Multi Pollutant Index (PW-MPI) values for different regions. Remarkably, the global PW-MPI in 2050 is projected to be similar to that in the Middle East in the year 2005. Northern India and the Arabian Gulf region, on the other hand, will suffer a marked increase in ozone levels. Source: Pozzer et al.
Ozonepollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.
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.
Probability distribution for the committed warming by GHGs between 1750 and 2005. Cutting HFCs, black carbon, tropospheric ozone, and methane can buy us about 40 years before we approach the dangerous threshold of 2°C warming. —co-author With indoor air pollution killing 1.6 From Molina et al.

Since 1990, nationwide air quality has improved significantly for the six common air pollutants: ground-level ozone; particle pollution; lead; nitrogen dioxide; carbon monoxide; and sulfur dioxide, according to the US Environmental Protection Agency (EPA) report “Our Nation’s Air - Status and Trends through 2008”. annual PM 2.5

has agreed to spend more than $161 million on pollution controls, enhanced maintenance and monitoring, and improved internal management practices to resolve Clean Air Act violations at its Texas City, Texas refinery. BP Products North America Inc. The company will also pay a $12 million civil penalty.
They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. Whereas nitrogen oxide concentrations dropped by 7% yearly from 2005 to 2009, they declined by just 1.7%
As with its predecessor legislation, the MAP-21 provides funding to areas in non-attainment or maintenance for ozone, carbon monoxide, and/or particulate matter.
BC is a significant component of particulate matter (PM) pollution, which has been linked to adverse health and environmental impacts through decades of scientific research. Most of this infrared radiation passes through the atmosphere, but some is absorbed by GHG molecules like CO 2 , methane, ozone and others. emissions in 2005.
Ethane reacts with sunlight and other molecules in the atmosphere to form ozone, which at the surface can cause respiratory problems, eye irritation and other ailments and damage crops. Between 2005 and 2014, the Bakken’s oil production jumped by a factor of 3,500, and its gas production by 180.
Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems. Two maps compare total annual sulfur dioxide amounts for India and China during 2005 (left) and 2016 based on Ozone Monitoring Instrument measurements. According to the results of the current study, these efforts are paying off.
Acetaldehyde is classified as a hazardous air pollutants (HAP) regulated under Title III of the Clean Air Act Amendments. They estimated year-2005 North American ethanol emissions of 670 GgC/y, with 440 GgC/y from the continental US. This is accompanied by a modest regional decrease in surface ozone (of order 1%).
The draft requires states to establish goals for reducing global warming pollution from the transportation sector and requires large metropolitan planning organizations to submit transportation plans to meet those goals. Title III, Reducing Global Warming Pollution , (the cap-and-trade title), has eight subsections.
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).

In 2005, Congress enacted the Renewable Fuel Standard as part of the Energy Policy Act (EPAct) and amended it in the 2007 Energy Independence and Security Act (EISA). Biofuels production has been shown to have both positive and negative effects on water quality, soil, and biodiversity. Barriers and opportunities.
The Advanced Collaborative Emissions Study (ACES), released today by the Health Effects Institute (HEI), also confirmed that the concentrations of particulate matter and toxic air pollutants emitted from NTDE are more than 90% lower than emissions from traditional older diesel engines (TDE). Earlier post.)
New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO.
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.
Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. The annual averages of ozone levels in study areas were between about 10 and 25 ppb.
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.
The study focuses on the period between 2005 and 2018 and tracks combustion emissions of various polluting compounds from various sectors, looking at every state in the contiguous United States, from season to season and year to year.
In a new study apportioning air pollution health burdens across US sectors, researchers at the Office of Air Quality Planning and Standards, US Environmental Protection Agency (EPA) determined that mortality from air pollution has fallen over time but that many sectors continue to pose a substantial risk to human health.
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
and ozone deaths, associated mortality rates, and population in G20 economies in 2015. and ozone worldwide in 2010 and ~385,000 in 2015, equivalent to 11.7% and ozone premature deaths in 2010 and 11.4% and ozone concentrations from transportation emissions resulted in 7.8 Transportation-attributable PM 2.5 Together, PM 2.5
