Daegu Sky Fine Dust 'Good' ... "Feel Safe to Go Out!"

Measuring Air Quality Using Mobile Air Pollution Monitoring Vehicles

Daegu Health and Environment Research Institute deployed a mobile air pollution measurement vehicle to monitor air quality in major recreational areas such as parks.

[Asia Economy Yeongnam Reporting Headquarters Reporter Se-ryeong Lee] The Daegu Health and Environment Research Institute announced that it confirmed the air quality in rest areas such as Duryu Park to be "Good" by preparing a mobile air quality measurement vehicle.

From October to November, the city stationed a mobile air pollution measurement vehicle at Duryu Park, Riverside Sports Park, and Daegu Stadium to continuously measure air quality for six items including particulate matter (PM-10), fine particulate matter (PM-2.5), and ozone (O3).

Particulate matter (PM-10) was at a level of 25?30㎍/㎥, classified as "Good (0?30)," and fine particulate matter (PM-2.5) ranged from 12?18㎍/㎥, showing levels from "Good (0?15)" to "Moderate (16?35)."

During the same period, the concentrations were measured to be relatively lower than the average concentration in the Daegu area, with particulate matter 15.6% lower and fine particulate matter 11.8% lower.

Sulfur dioxide and carbon monoxide levels were similar to the city’s average urban air concentrations, and nitrogen dioxide and ozone showed some variation depending on the measurement location but were much lower compared to air quality standards.

It was confirmed that particulate matter concentrations increased during commuting hours and decreased after 3 p.m., and weekends, Saturday and Sunday, showed lower levels than weekdays.

Do Ju-yang, Director of the Health and Environment Research Institute, said, “We will continue to provide air quality information using the mobile air pollution measurement vehicle,” and added, “We urge the public to check real-time air quality conditions from December to March, when particulate matter concentrations tend to rise, to protect respiratory health.”
