A New All Season Passive Sampling System for Monitoring Ozone in Air,centrations ranging from 3 ppb to 1000 ppb based on one-day exposure and 0.1 ppb to 140 ppb for a monthly exposure period. It is also reasonable to conclude that the new passive sampling system can be used for eight-hour exposure study because of the low field blanks and high sampling rates.

Seasonal Differences in the Levels of Gaseous Air Pollutants in the Vicinity of a Waste Dump,same as the waste dump direction), the contribution of air pollution from the direction of the waste dump at the measuring site is significant, but that does not necessarily mean that the pollutants originated from that source.
