A system has been constructed which provides stable, realistic urban
atmospheres with pollutant mixtures at concentrations and proportions relevant
to those found at roadsides in urban areas. This system has been used in
conjunction with a range of field sites to assess the impacts of urban pollution
mixtures on a broad range of plant species of contrasting morphological and
functional types. Impacts of pollution treatments have been assessed in terms of
visible injury symptoms, growth, rates of stomatal conductance, senescence, and
leaf surface characteristics. Our data clearly demonstrate that levels of pollutant
mixtures typical of urban areas do have species-specific, direct effects on plant
growth and may make plants susceptible to other environmental stresses.
