"Smog tower" nghĩa là gì?
17 Feb, 2022
"Smog tower" -> nghĩa là tháp dùng quạt gió và lưới lọc để làm sạch, thanh lọc không khí.
Ví dụ
A walk of up to one km in three different directions (hướng) from the smog tower in Connaught Place with a handheld air quality monitoring device has revealed fluctuating levels of the chief pollutant, PM 2.5.
Whereas the value of PM 2.5 decreased as you moved away from the tower, which is in contradiction (mâu thuẫn) to normal scenario. The readings indicate the efficiency of the smog tower is not enough to clean the air to the extent it is needed.
A 2020 study in the Lancet found there were 1.67 million deaths in the country attributable (là vì) to air pollution in 2019 including almost 17,500 in Delhi. In 2018 China built a much larger 60-metre smog tower in the polluted city of Xian, but the experiment has not spread to other cities so far.
A new attempt at purifying (làm sạch) New Delhi's notoriously polluted air will see forty giant fans push out filtered air in the heart of the Indian capital's posh downtown shopping district. But the $2 million "smog tower" has no shortage (thiếu) of doubters who say it will not help a city notorious (có tiếng xấu) for some of the world's dirtiest air.
