Pollution in Korea

[1] The causes of environmental pollution, both in South and North Korea, can be found in population growth, urban concentration, and industrial structure, similar to the rest of the world.

[4] Particulate matter occurs when the material is crushed, sorted, transported, or otherwise mechanically treated or burned, synthesized, or decomposed.

[4] In the 1960s and 1970s, the use of fossil fuels and the reckless attraction of industries as a growth-oriented development logic caused air pollution in Korea.

[10] Common dust is large in particle size, so most of it is filtered out of the nasal hair or bronchial mucosa, which has a very small impact on the human body, but fine dust accumulates better in the body without filtering out the human nose hair, mouth, or bronchial tubes.

[11] The International Cancer Research Institute under the World Health Organization(WTO) has designated fine dust as a first-degree carcinogen.

[14] These substances cause turbidity, eutrophication, and lack of dissolved oxygen, and if not purified, they contaminate lakes and rivers, destroying the water ecological environment.

[14] Major pollutants that generate domestic sewage include households, lodging, food service, and public baths.

[2][page needed] Since it contains a lot of high-concentration organic substances, it increases water pollution if not properly managed and treated.

[2][page needed] 30tons of phenolic liquid leaked from Doosan Electronics in Gumi Industrial Complex into Nakdong River.

30 tons of phenol flowed into Okgyecheon, a tributary of the Nakdong River, and then went to the water intake plant of Daegu citizens.

"[16] Government prosecutors condemned the company and other factories for water pollution and instituted an immediate 70-day crackdown; they also arrested six Doosan officials.

[16] A tanker truck carrying 20tons of sulfuric acid crashed in the upper stream of the Nakdong River, killing a group of fish.

[18] The wastewater storage tank of the Seongseo Industrial Complex was deteriorated, causing corruption and urgent repair.

It is the case of discharging 20 tons of waste oil that were being stored in the wastewater storage tank by using the rain gap during the rainy season.

[26] The detection rate of each city and province based on soil pollution concerns is high in the order of Gyeonggi, Seoul, and Busan.

[34][page needed] In the case of the Taedong River, about half of the sewage and excrement flows into it without being purified, so that residents who drink the tap water are complaining of stomach pain.

[35][page needed] It is estimated that North Korea's major rivers passing through large cities and factories and mining areas are severely polluted.

[28] Reusable materials are mainly paper, glass, iron, rubber, clothing, plastic, bottles, and Non-ferrous metals, whose reuse is limited by a lack of technology.

This is the appearance of downtown Seoul on May 7, 2021, when there was a lot of fine dust.
