The immediate area air monitoring results indicate that concentrations in the air should not cause any adverse health effects. However, air behaves differently at different levels within the atmosphere. The plume of air going up into the sky may travel quite a distance and may even travel in a different direction than the air at ground level. That being said, air concentrations are a function of volume, speed, and degradation over time and space (distance in the x,y, and z direction). So as it spreads the concentrations become more dilute. I would expect you would have more exposure to being near a running car than to anything from the Palestine spill site
