Moreover, According to environmental experts, the phenomenon of temperature inversion with some seasonal breeze makes the northern provinces’ air quality poorer. Data from automatic air monitoring points in recent days show that air quality in many northern localities of Vietnam, especially in Hanoi, is at an alarming level. The air quality in the capital city has deteriorated to “very bad” or even "unhealthy" levels in many places. Experts advise that when the air is polluted, people should limit their outdoor activities and avoid prolonged exercise. #sseayp2022#DG8#bethechange
