SYMPTOMS OF DAMAGE DUE TO ENVIRONMENTAL POLLUTANTS

Contaminants in water or the air can also affect plant health. These pollutants can cause a wide range of symptoms, many of which may look like damage caused by nutrient abnormalities or even insect damage. In this photo, the MARGINAL BRONZING symptoms of this Schefflera plant are due to an exposure to sulfur dioxide. High levels of sulfur dioxide can sometimes be found near plants that burn coal.
