LANCASTER – The 2021 “State of the Air” report from the American Lung Association finds that the Lancaster County area improved to its best ever year-round level of fine particle pollution and met the national air quality standard, but still ranks as 36th worst in the nation for this pollutant. Days with high levels of particle pollution worsened significantly, earning the area an “F” grade. The frequency of days high in ozone smog improved, but this pollutant remained a threat giving the area a “C” grade. The Lung Association’s Director of Environmental Health, Kevin Stewart says there are still many days when the air pollution levels are high enough to harm health and trigger asthma attacks, heart attacks and stroke, placing children, older adults, and people living with chronic lung and heart disease at particular risk. Ozone and particle pollution are the nation’s most harmful and widespread air pollutants. You can see the full report by clicking on the banner below.
