Environmental Club Update, April 2015
Ground-level ozone, a colorless gas, is one of the major components of smog. Sources of this ozone include electric utilities, motorized vehicle exhaust, and gasoline vapors. Ozone can cause health problems in both animals and plants. Resulting problems in plants include chlorosis (yellowing of the plant leaves), necrosis (premature death of cells and living tissue in the plant leaf), and purpling/stippling (the leaf surface turning purple due to ozone exposure).
Ozone gardens are used to monitor the effects of ground-level ozone on plants. At Christ Church Episcopal School (CCES), the ozone garden of cutleaf coneflower plants is located near the traffic circle where students are picked up and dropped off. This is an ideal location for monitoring ozone impacts due to the plethora of idling cars there each day. CCES is a participant in the South Carolina GreenSteps program, which promotes environmental awareness and action in schools. The ozone garden is just one of the many projects that CCES participates in order to be recognized as a GreenSteps school.
This past summer, students enrolled in the International Baccalaureate (IB) Environmental Systems & Societies class collected data from the CCES ozone garden. On a weekly basis, students monitored leaves of 18 plants, rating each leaf in the extent of purpling, necrosis and chlorosis. The higher percentage of chlorosis and purpling on a leaf indicates greater damage from ground-level ozone. Necrosis, death of leaf tissue, can be a result of ozone or other environmental factors. The data collected will be entered into a nationwide database in an effort to monitor ground-level ozone impacts on a larger scale.
Meanwhile, back at CCES, we are doing our part to reduce ozone concentrations. We have an active anti-idling campaign which will improve air quality for all of us and for the ozone garden!
