Risk of fine dust
The World Health Organization (WHO) has designated BC (black carbon) as a first-level carcinogen in diesel particulates.
Fine dust is composed of ionic compounds such as nitrate (NO3-), ammonium (NH4 +) and sulfate (SO42-), carbon compounds and elements. The World Health Organization (WHO) has designated the BC (black carbon) emitted from diesel as a first-level carcinogen.
When exposed to fine dust for a long time, one’s immunity is rapidly lowered, making it susceptible to various diseases such as cardiovascular diseases, skin diseases, and eye diseases, as well as respiratory diseases such as colds, asthma and bronchitis. Bronchi are particularly susceptible to penetration by ultrafine dust, with a diameter of less than 2.5μm, thereby gaining passage deep into the lungs of the human body.
