Very good air quality was recorded on Yom Kippur the holiest day in Jewish calender

Very good air quality was recorded on Yom Kippur in most monitoring stations of the national air monitoring system, which is supervised by the Ministry of Environmental Protection.
With the advent of the holiday, concentrations of nitrogen oxides - a marker of air pollution from vehicles - drastically decreased in the transportation stations in Haifa, Gush Dan and Jerusalem. The concentrations of nitrogen oxides on Yom Kippur in the transportation stations in the large cities were between 1.0 and 12.0 parts per billion.
The significant improvement in air quality on Yom Kippur illustrates the effect of transportation as the main source of air pollution in the centers of large cities. By contrast, on Yom Kippur eve, the concentrations on Ha'atzmaut Street in Haifa reached a low of 181.3 parts per billion, while on Yom Kippur the maximum concentration was 3.3 bp, in central Jerusalem there were concentrations of up to 81.7 parts per billion and 12 thousand on Yom Kippur; And in the center of Tel Aviv, the concentrations dropped from 34.8 to 3.5 ha, and the benzene concentrations originating in transportation decreased at the Hadar station in Haifa, from 0.22 to 0.09, and at Bar Ilan in Jerusalem From 0.47 to 0.05 ppm.
It should be noted that the power stations work on Yom Kippur at a slightly lower load than usual, and Israel's largest industry is working normally - and therefore in the stations adjacent to the industry (such as Kiryat Binyamin in Haifa) there are no significant effects of air pollution in some of the pollutants. For example, in Kiryat Binyamin (located downstream from the refinery) there was even an increase in the maximum concentration of benzene compared to the eve of Yom Kippur, without deviating from the environment.
As with every Yom Kippur, the drastic decline applies only to nitrogen oxides and not to particles passing through the airways or secondary pollutants. As a general rule, nitrogen oxides cause various symptoms of respiratory diseases and reduce the body's resistance to bacteria. Exposure to very high concentrations of nitrogen dioxide, a pollutant that harms health within nitrogen oxides, can lead to increased inflammatory responses in the respiratory tract of healthy people in Chronic Obstructive Pulmonary Disease (COPD) patients as well as asthma patients and increases the frequency of respiratory symptoms (Seizures).
