Plants and Air Quality
What affect does air pollution have on different plants?
This depends whether it is point source (nearby) or not, also the type of
pollutant such as ozone.
The following should be helpful:
Anthony Brach Ph.D.
Air pollution is generally not good for plants. Different plant species
will have different abilities to tolerate the bad effects of air
pollution. In general, plants that are affected by moderate air
pollution are not as strong, they grow poorly and they end up dying
because of other problems. Air pollution affects many different parts
of the plant either directly or indirectly. Obviously the leaves are
directly affected. Less obvious are the effects on the soil.
Pollutants will affect the nutrients the plant needs to grow. Plants
react to air pollution in basically the same way that all organisms
including ourselves react to air pollution.
