EPA Proposes Updates to Air Quality Standards for Ground-Level Ozone

Cinnaminson, NJ – WEBWIRE

In November, the U.S. Environmental Protection Agency (EPA) proposed to strengthen the National Ambient Air Quality Standards (NAAQS) for ground-level ozone. The agency reported that it took this action based on extensive scientific evidence about ozone’s effects.
“The proposed updates will improve public health protection, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma,” wrote the EPA. The agency proposes to make revisions to the primary and secondary NAAQS for ozone to provide requisite protection of public health and welfare, respectively. The EPA is proposing to revise the primary standard to a level within the range of 0.065 to 0.070 parts per million (ppm), and to revise the secondary standard to within the range of 0.065 to 0.070 ppm.
Tropospheric ozone, also known as low level ozone, is recognized by the World Health Organization (WHO) and the EPA as a pollutant that causes respiratory problems for both humans and animals.  High levels of ozone are known to cause respiratory problems and reduce lung function. It is also a trigger for some people who suffer from asthma. In addition, ozone is a significant component in the creation of smog.
“Both ozone and smog are health concerns for not only people spending time outdoors, but also for people who are indoors as it can infiltrate into homes, schools and businesses,” said Joseph Frasca, Senior Vice President of Marketing at EMSL Analytical, Inc. “Ground-level ozone is not just an issue in major cities during the summer as some people believe. It has been observed during cold months in some high elevation areas in the Western United States and can also be transported long distances by wind so even rural areas can experience high ozone levels. At EMSL, we offer testing services and sampling supplies to identify ozone to help protect workers, the public and the environment.”
EMSL recently sponsored an online video about ground-level ozone and health risks that can be seen at:
