Air pollution drops drastically on Yom Kippur

A phenomenon unique to Israel occurs once a year – the massive drop in air pollution particularly in major urban centers on Yom Kippur. This year was no exception, according to the Environmental Protection Ministry. According to data released Saturday night, monitors in the Dan Region, Jerusalem and Haifa picked up a massive drop.    
Nitrogen suspended particles are a good indication of the levels of pollution in the air, the ministry said. In the Dan Region, the morning before the holiday, there were 84 parts per billion in the air. That dropped to 1-8 parts during Yom Kippur.
In Jerusalem, there were 114 parts per billion at 2:00 p.m. the afternoon before the fast. That dropped to between 1-8 parts per billion as well during the course of Saturday. In Haifa, 78 parts per billion were recorded the morning before the fast and 1-7 during the fast.
