What are the pollutants in the air?

Most common among the local pollutants are sulfur dioxide, fluorides, ammonia and particulate matter. Widespread pollutants consist primarily of “oxidants”. Ozone, the major component of oxidants, is produced in the atmosphere during a complex reaction involving nitrogen oxides and reactive hydrocarbons, components of automobile exhausts and fossil fuel combustion. As this process proceeds only in sunlight, it is called a photo-chemical reaction. The vegetation injury, which can result from oxidant build-up in the air, can occur over large rural areas covering hundreds of square kilometres.

The symptoms appear as a yellowing or chlorosis of the leaf, and occasionally as a bronzing on the under surface of the leaves. Different plant species and varieties and even individuals of the same species may vary considerably in their sensitivity to sulfur dioxide.

What are the effects of ozone on plants?

Its effect on plants was first observed in the Los Angeles area in 1944. Since then, ozone injury to vegetation has been reported and documented in many areas throughout North America, including the southwestern and central regions of Ontario. Throughout the growing season, particularly July and August, ozone levels vary significantly. Periods of high ozone are associated with regional southerly air flows that are carried across the lower Great Lakes after passing over many urban and industrialised areas of the United States. Localized, domestic ozone levels also contribute to the already high background levels. Injury levels vary annually and white bean, which are particularly sensitive, are often used as an indicator of damage. Other sensitive species include cucumber, grape, green bean, lettuce, onion, potato, radish, rutabagas, spinach, sweet corn, tobacco and tomato. Resistant species include endive, pear and apricot.

What are the factors that affect ozone?

Susceptibility to ozone injury is influenced by many environmental and plant growth factors. High relative humidity, optimum soil-nitrogen levels and water avail ability increase susceptibility. Injury development on broad leaves also is influenced by the stage of maturity. The youngest leaves are resistant.
