JEFFERSON CITY, MO, -- Gov. Jay Nixon announced the Missouri Department of Natural Resources has awarded subgrants to the St. Louis metropolitan area to continue monitoring and tracking fine particulate matter or PM2.5. St. Louis City will receive $63,000 and St. Louis County will receive $25,000 for a total of $88,000 in subgrants. During tough economic times, this infusion of grant funding will help the city and county protect citizens and the environment by continuing to collect air samples in the St. Louis metropolitan area.
The award will fund the monitoring through March 31, 2010. The Department will use these samples to help judge whether the area is in compliance of the National Ambient Air Quality Standards or NAAQS for fine particulate matter. The PM2.5 network provides high quality data for NAAQS compliance, Air Quality Index reporting and source distribution. This data is used to promote public health by monitoring NAAQS compliance, reducing visibility impairment in scenic areas and providing Air Quality Index reports for susceptible people whose health can be affected by air pollution.
"Data collected through this monitoring has met and surpassed data quality and completeness requirements each year since its commencement and allows the Department to see the continued effectiveness of air pollution control strategies that have been implemented," said Department of Natural Resources Director Mark Templeton. "Gauging the success of our air pollution control strategies is an important part of protecting air quality for all Missourians."
Particles in the air are a mixture of solids and liquid droplets that vary in size and are often referred to as "particulate matter." Some particles, those less than 2.5 micrometers in diameter, pose the greatest health concern because they can pass through the nose and throat and get deep into the lungs. These are known as fine particles. Micrometers 2.5 in diameter are just a fraction of the diameter of a single human hair. Particles larger than 2.5 micrometers are not usually inhaled deeply into the lungs, but they can cause some other health effects. Particles less than 10 micrometers in diameter but more than 2.5 micrometers are known as coarse particles.
Currently, the St. Louis metropolitan area has one site over the annual PM 2.5 standard, which is in Illinois. Several other sites are near the standard. Kansas City, including Kansas sites, Springfield, and all outstate areas are in compliance with the annual standard.
The U.S. Environmental Protection Agency's Region 7, through the Missouri Department of Natural Resources, has provided funding for this project under Section 103 of the Clean Air Act. The Department is committed to working closely with communities to assist with funding efforts that improve air quality in Missouri.
