Air pollution crackdown expands with fine dust monitoring drones Updated: 2019-11-11 13:31:57 KST

A drone with equipment that absorbs air pollution flies into Banwol Industrial Complex, an area with many textile plants that emit smoke.
The drone stops at one of the smokestacks, sucks in air and measures the amount of fine dust.
This is the drone Korea's Environment Ministry's supervisory team on fine dust uses to reduce air pollution.
It's expected to make enforcement much more efficient at hard-to-access places.
Using drones, the detection rate of illegal emissions doubled to 42 percent.

"The concentration of fine dust soared from 24 micrograms per cubic meter to 300 as the drone approached the top of the smokestack."

It only takes a minute for a drone to collect and measure one liter of air much faster than sending a person to collect a sample manually, which takes three to four hours.
The drone also measures and analyzes more than 60 types of air pollutants.

Currently limited to few metropolitan offices, the Environment Ministry plans to implement the drone monitoring system at all regional environmental offices by the end of the year.
