The emission of fine dust called fugitive dust reaches about 115,000 tons per year'날림먼지 배출, 연간 11만톤에 달해'

[The Hwankyung Ilbo] According to the data submitted by the Ministry of Environment to Democratic Party lawmaker Shin Chang-hyun, the amount of fugitive dust scattered to the atmosphere from roads and construction sites without a certain outlet is 114,774 tons per year, of which the ultrafine dust (PM 2.5) accounts for 16,102 tons.

The contribution of ultrafine dust by sources was as follows: ▷ fugitive dust from roads (40.6%) ▷ construction site (17.1%), and the emissions from agriculture and livestock industry were 12.5% ​​(2,028 tons) and 11.4% (1,840 tons) respectively.

In addition, the amount of ultrafine dust generated in the school grounds and other areas is 1,610 tons (9.9%), which indicates that students are exposed to fine dust.

Meanwhile, it is pointed out that it is necessary to improve the calculation method of fine dust emission because it does not measure the indirect emission due to secondary dust generation by classifying agricultural and livestock activity only as fugitive dust, which accounts for a large part of ammonia emission.
