“The ultimate goal is to use plants to detect periods of ozone exposure that may also affect human health.”
William Manning
“The previous standard was lots of ozone for a short period was bad. Now we're going to a more stringent standard that's even a small amount for a long period time. We've been in this standard for about two years. It?s very difficult to obtain.”
Michael Morris
“Generally, the ozone hole remains close to the (South) Pole, so for human populations, we have to keep an eye on it, and we have to be a bit worried about it, but we don't have to jump to extremes here.”
Paul Newman
“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.”
“It's well-documented that both periodic episodes of high ozone exposure and chronic moderate ozone exposure can be harmful to plants, ... We know this from other regions of North America including national parks such as Sequoia and Great Smoky Mountains.”
David Peterson
“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.”
Geir Braathen
“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.”
