Smoke from wildfires in Canada may spike ozone levels here

PERRYVILLE — The May ozone readings are in and it looks like the smoke from the Canadian wildfires have bumped up local ozone readings.

According to the latest report received from the Southeast Missouri Regional Planning Commission the averages this past month were 51 ppb in Bonne Terre and 53 ppb at Farrar.

The report states: “However, there were two days May 24 and 25 above 75 ppb both recorded at Farrar. Comparatively, ozone levels have increased by 9 ppb, or approximately 22 percent, compared to the previous season.

“This can be attributed to a number of factors including ongoing wildfires in Canada.

“Given the impact of these wildfires on ozone levels in May, it is predicted that the monitors will continue to record higher AQIs in June.

“It is essential to note the EPA’s National Ambient Air Quality Standard is 75 ppb for an 8-hour average. Thus, the recorded levels are approaching or exceeding these established standards, warranting our attention.

“We will continue to monitor and assess the situation closely to understand the effects of these events on air quality.”
