“The reservoirs of ozone-depleting chemicals found in old fridges and air-conditioning systems may be greater than anticipated, and if this continues into the future then the projection of ozone hole recovery in 2050 may have to be extended.”
Dale Hurst
“Even though levels of organic chlorine in the stratosphere are going down, we saw severe ozone depletion in the Arctic this past winter.”
“The ultimate goal is to use plants to detect periods of ozone exposure that may also affect human health.”
William Manning
“We asked ourselves, 'If we have a lot of ozone in the air on a beautiful summer afternoon, what does that do biologically to humans and plants?' ”
“You could say that the ozone situation is stabilizing at a low level. We are approaching the maximum of ozone depletion, it is kind of leveling off, but it is still too early to say that the situation is improving.”
Geir Braathen
“The size of the ozone hole this year was expected to be in the same region as in 2000 and 2003, the two largest ozone holes recorded so far.”
“All around us, we see plants that have endured chronic ozone exposure with no apparent adverse symptoms except premature aging and reduced reproduction, ... Could this relate to the human experience? That's what we need to find out. But, in the meantime, it's important for us to determine how ozone exposure affects our forests, our wetlands, our crops, and even our backyards.”
