3.
2, the oil smoke or smaller of dried bean angle when cooking, the content testing its PM2.5 is 124ug/m
3.
Recording its PM2.5 content when 3, making vinegar-pepper cooking shredded potato is 136ug/m
3
4, when making is boiled in water for a while, then dress with soy, vinegar, etc. and sauted Chinese cabbage, the PM2.5 in kitchen is 133ug/m
3, the particle content in oil smoke can be said to be passable.
5, PM2.5 content during capsicum stir-fry meat is the highest, and its numerical value reaches 187ug/m
3.
Rural kitchen PM2.5 links together with us closely, focuses on reducing rural kitchen air pollution and promoting health, has become the important content of rural kitchen reform.
