"The other thing I have learned (as a chemist, not a biologist) is that similar symptoms on plants can arise from different causes, partly because plant responses to stress at the biochemical level can be similar, whether the stress is drought or air pollution. However, there are some responses that are visible and characteristic – e.g. stippling of leaves by ozone. That can be misleading – some plants may show stippling, and may shed their leaves early, and yet this may have little or no effect on plant growth. In other cases, plant growth may be hindered by air pollutants, but with no visible injuries.
