is a natural beneficial ozone layer in the upper atmosphere that prevents
harmful radiation from the sun from reaching the ground and causing skin
cancer. At ground-level there is ozone as well, but this ozone can often
be harmful to human health. It also injures plants.
The investigators believe that ground-level ozone is one of the most important air pollutants
affecting crop production and forest health.
We need more
information on ozone concentrations in agricultural and forested areas, and a
better understanding of how plants respond to ozone, before we can tell whether
current air standards sufficiently protect vegetation against ozone.
