It is called condensed fine dust when the substance is discharged into a gas and then cooled to become dust. Recently, this condensed fine dust has been rampant. If people are exposed to fine dust for a long period of time, then their immunity can decrease rapidly, which can lead to exposure to various respiratory diseases, and skin diseases such as cardiovascular diseases, atopic diseases, and eye diseases. In particular, ultrafine dust with a diameter of less than 2.5 μm is easy to penetrate deep into the human body, and sticks to the bronchial tubes and lungs, causing various diseases.
The Ministry of Environment has not been able to come up with a measurement method for "condensing fine dust," which is fatal to the human body, so it has been found that it has not even been able to grasp the exact status of emissions. Currently, "condensing fine dust" is not included in the fine dust calculation announced by the Ministry of Environment, and it has been confirmed that there is no emission business management system.
Condensable fine dust has a multi-process structure composed of small particles, so it is likely to be inhaled into the human body along with toxic substances, including harmful substances such as formaldehyde and nickel, which are known to be more harmful than general fine dust.
Although it is pointed out that the management is insufficient compared to the U.S. and Europe, which have separate measurement methods, the Ministry of Environment says, "It is difficult to grasp the official status until standardized process test standards for condensed fine dust are prepared."
Thus, one of the congressmen claims that "fine dust is emerging as the biggest threat to the public's health, and that we need to systematically seek mid- to long-term management and regulatory measures such as the cost of equipment used in the process of measuring condensed fine dust".
