Impact of Auto Exhaust Pollution on Trees | Chapter 03 | Advances and Trends in Agricultural Sciences Vol. 2
Environmental pollution and its impact
on living organisms is worldwide problem. The pollutants discharged from the
automobile activities are particulate matter, heavy metals (Pb and Cd), carbon
dioxide, oxides of nitrogen and oxides producing toxic effects on plant growth.
The other common effects are reduced yield of flowers, branch length, leaf area
and reduction in seed germination percentage. This book chapter provide some
information about the impact of auto exhaust pollution on plant growth. The
importance of tree in the urban environment cannot be ignore. A number of
studies on the effects of air pollution on tree growth have been carried out by
researchers over the past many years in developed and in developing countries.
Trees play an important role in maintaining the ecological balance, pollution
reduction and lessening the burden of pollutant by absorbing pollutants.
However, trees in urban cities are growing in a severe stressful environment
due to incomplete burning of fossil fuel and badly maintained vehicles
resulting shorten life span of plant. The growth of plants could be affected by
several reasons and one of them is the presence of toxic pollutants derived
from the auto vehicular exhaust emission.
