ETHYLENE: AN URBAN AIR POLLUTANT

EHTYLENE AIR POLLUTION IS A CONTINUAL SOURCE OF STRESS FOR PLANT GROWTH AND DEVELOPMENT IN AN URBAN ENVIRONMENT. IN THE WASHINGTON, D.C. AREA, EHTYLENE CONCENTRATIONS RANGED FROM 700 PPB IN THE CITY CENTER TO 39 PPB IN AREAS OUTSIDE THE CIRCUMFERENTIAL BELTWAY. PLANTS GROWN IN THESE CONCENTRATIONS OF ETHYLENE, USING CONTROLLED ENVIRONMENT CHAMBERS, EXHIBITED TYPICAL SYMPTOMS OF ETHYLENE TOXICITY: REDUCED GROWTH, PREMATURE SENESCENE, AND REDUCED FLOWERING AND FRUIT PRODUCTION. RESOLUTION OF THE ETHYLENE AIR POLLUTION PROBLEM ULTIMATELY RESTS ON CONTROLLING THE NATURE OF EMISSIONS, ESPECIALLY FROM URBAN TRANSPORTATION. /DOT/ /DOT/
