Recently, fine dust from China raided the Korean peninsula for several days. It is said that this year's fine dust concentration will be even thicker than previous years. People with respiratory diseases such as colds, asthma, bronchitis, and ones with weak lungs are suggested to secure themselves by using filtering products.
However, now, remarkable nanotechnology techniques are being developed to reduce air pollution in Korea. Scientists are collecting and burning soot from a factory chimney using boron nitride nanotubes to build a ceramic filter that diminishes fine dust.
A scientist in the laboratory of KIST (Korea Institute of Science and Technology) explains the process of making and experimenting nano ceramic filter: "Fine dust is burned when it is heated to more than 350 degrees Celsius and decomposed into carbon dioxide and water, but boron nitride nanotubes can’t burn up to 900 degrees. By adjusting the size of the filter according to the fine dust, it can be slowed down and then be taken on to the specific spot. "
Not only the air pollution, but KIST also aims to apply recycled nanoceramic filter technology within many different aspects such as thermal power plants to be used in viral purification, water treatment, food refining, aerospace, electronics, automobiles, and nuclear power. This technique can also be used for personally customized masks, providing a healthier lifestyle for all people.
However, the Food and Drug Administration commissioned the Korea Living Environment Research Institute (KFDA) to examine the toxicity of lungs and liver in rats that ingested a large number of silver nanoparticles, whether it is considered to be safe to apply to our daily lives. Choi Jin-hee, professor of environmental engineering at Seoul City University, said, "The toxicity of nanomaterials can vary greatly depending on their physicochemical properties" therefore, it requires more research to ensure the applicability of the technology.
