Air quality in Israel was excellent over Yom Kippur, the Environmental Ministry said Saturday night. According to measurements recorded at Ministry stations around the country, the improvement began immediately after the beginning of the holiday, as Co2 levels, associated with vehicle exhaust, fell dramatically, especially in the Dan region and in Jerusalem. In the Tel Aviv area, for example, pollution over the holiday was measured at 1 to 8 parts per million, compared to 84 parts per million on the morning before Yom Kippur.
