and ozone at or above the current standards have been linked to neuroinflammation and high risk of Alzheimer’s disease (AD). suggesting long-term exposure to PM 2.5 , as well as ozone above the current US EPA standards, are associated with increased risk of Alzheimer’s disease. Exposures to concentrations of PM 2.5 g/m 3 in PM 2.5
Furthermore, myclimate accounts for other warming effects of aircraft emissions (through changes in the ozone layer, initiation of contrails, formation of cirrus clouds, etc.) A documentation for the myclimate calculator includes other aspects of the method used.).
In a cohort study of a subset of 2050 newborns from the Children’s Health Study in southern California, researchers at the University of Southern California (USC) found that an increase of 2 standard deviations in prenatal exposure to particulate matter in air pollution was associated with higher newborn total thyroxine (TT4) measures.
The largest systematic study ever conducted of human volunteers exposed to ozone air pollution has found no evidence of effects on the heart in its healthy, older participants, but did find effects on the volunteers’ ability to breathe, even at low ambient levels. Possible pathways by which ozone may cause adverse health effects.
University of California, Davis researchers will receive $2.8 These environmental impacts are not fully documented, according to Tom Tomich, director of the Agricultural Sustainability Institute at UC Davis. million in new grants to study the use and impacts of escaped nitrogen from agricultural production.
A new study led by researchers from Northwestern University projects that if electric vehicles replaced 25% of combustion engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. The open-access paper is published in AGU’s journal GeoHealth.
They documented a decrease of 30% in 2018 compared to 2005, equivalent to about 30,000 avoided early deaths, or people who did not die early as a result of pollution. a, Source–receptor matrix showing total early deaths per year for 48 × 48 states (right), and its breakdown into PM 2.5 - and ozone-attributable impacts (left).
Results from CHIE studies are used to inform the periodic review of National Ambient Air Quality Standards (NAAQS) for common pollutants, such as ozone and particulate matter (PM), and advise other policy decisions. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants.
A scholarly literature has documented this process in fields as diverse as engineering, risk reduction, management, and urban studies.
