As a result, a person may experience a stroke, angina, or a heart attack. According to the findings of the research, persons are most at danger from nitrogen dioxide exposure. The finest particles are found in nitrogen dioxide. Within the first hour of coming into touch with humans, it may trigger the syndrome.
