Current levels of the air pollutant ozone
lower yields of
susceptible crops and impair forest health in many regions of the
United States and elsewhere worldwide (Booker et al. 2009;
et al. 2001).
There continues to be a
need for research and assessment of ozone effects on crops and
forests to determine severities of impact, estimate economic costs,
project future effects, and possibly improve plant tolerance to ozone
The NE-1030 project
facilitates collaboration and communication among scientists in the
United States and other countries worldwide who are actively involved in research
on plant responses to ozone.
The project (under various
designations) has been active within USDA-CSREES for 30+ years.
Scientists involved with the project have authored more than 500
scientific publications, provided the scientific underpinnings for
many federal and state ozone air quality standards, and communicated
with the public in various ways concerning plant responses to ozone.
In addition, the project seeks to expand its outreach
by encouraging participation of other interested scientists,
informing state extension services of our activities, and educating the public
about the effects of ambient ozone on plants.
JUST RELEASED -
The Ozone Pollution Learning Module, developed by Sabrina
Chrzanowski and Dennis Decoteau at Penn State University. The
module is designed to educate students about ground level ozone
pollution and is most appropriate for grades 9 - 12.
Describe the spatial - temporal
characteristics of the adverse effects of current ambient ozone levels
on crop productivity, including the development of numerical models to
establish cause – effect relationships that apportion the ozone
Assess the effects of ozone on
structure, function and inter-species competition in managed and native
plant populations, including alterations in their nutrient quality.
Examine the joint effects of ozone
with other growth regulating factors (e.g., carbon dioxide, temperature)
that are expected to vary with ongoing climate change on crop growth and
Examine the physiological and
molecular basis of ozone toxicity and tolerance in plants.
Multistate Snap Bean
Snap bean varieties with
differing sensitivity to ozone are being using at NE-1030
project locations nationwide to study plant responses to ambient ozone
Results of the study are
being used for ozone toxicity research, numerical modeling of plant
responses to ambient ozone, and development of educational materials
for demonstrating effects of ambient ozone on plants.
