Welcome to the NE-1030 Project

"Characterization and Mechanisms of Plant Responses to Ozone in the U.S."
Annual Meeting

Project Overview:

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; Krupa 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 damage.

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.

Project Objectives:

  • 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 contribution.

  • 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 productivity.

  • Examine the physiological and molecular basis of ozone toxicity and tolerance in plants.

Multistate Snap Bean Project:

Snap bean varieties with differing sensitivity to ozone are being using at NE-1030 project locations nationwide to study plant responses to ambient ozone pollution.

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.
