Study links PM2.5 pollution with millions of preterm births globally

Green Car Congress

million preterm births globally—or 18% of all pre-term births—were associated with outdoor exposure to fine particulate matter (PM 2.5 ).The Environment International. Recent research has suggested that exposure to air pollution could also be a risk factor. The open-access study is published in the journal.

International study finds air pollution leads to millions of hospital visits for asthma attacks worldwide

Green Car Congress

Air pollution—specifically PM 2.5 , ozone and NO 2 —could be to blame for up to 33 million emergency asthma attack visits to hospital a year, according to a new open-access study published in the journal Environmental Health Perspectives. Approximately 95% of the world’s population lives in places with unsafe air.

Even so, during 2010-2014, people in parts of California, Arizona, Colorado, Texas, the Midwest and the Middle Atlantic still experienced more than 15 days a year in which ozone levels exceeded the US health-based air quality standard of 70 parts per billion (ppb) averaged over eight hours.

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

An international team of researchers has shed light on one way new particles are forming in the upper troposphere. There are no factories or farms, and planes are thought to make up most of the pollutants in this area. This is important, especially in the relatively clean upper troposphere. The emission sources are limited up there.
