대기 오염 감시에 드론이 '최고'...적발률 '껑충'<br /><br />The uses of drones is expanding... even to the monitoring of air pollution.<br />It's a far easier and faster way to inspect emissions from factories and is twice as effective in finding violators.<br />Our Choi Jeong-yoon reports. <br />A drone with equipment that absorbs air pollution flies into Banwol Industrial Complex, an area with many textile plants that emit smoke.<br />The drone stops at one of the smokestacks, sucks in air... and measures the amount of fine dust.<br />"The concentration of fine dust soared from 24 micrograms per cubic meter to 300 as the drone approached the top of the smokestack."<br />It takes just 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.<br />The drone measures and analyzes more than 60 types of air pollutants.<br />It's expected to make enforcement much more efficient at hard-to-access places.<br />Using drones, the detection rate of illegal emissions doubled to 42 percent.<br />Korea's Environment Ministry plans to implement the drone monitoring system to all regional environmental offices by the end of the year.<br />Choi Jeong-yoon, Arirang News. <br />
