    Evaluation of Different Shrub Species for Carbon Uptake and Pollution Removal


    The aim of this work was to evaluate the ability of seven shrub species (Arbutus unedo, Elaeagnus x ebbingei, Laurus nobilis, Ligustrum japonicum, Photinia x fraseri, Viburnum lucidum, Viburnum tinus) to absorb and store CO2 and to remove some anthropogenic pollutants (including heavy metals and particulate matter) from the soil and the air. Plants were grown in 5-L containers arranged in a randomized block design with six blocks and two plants per species in each block. CO2 uptake and carbon allocation were determined in 2010 and 2011 using combined measurements of leaf gas exchange and biomass. Carbon assimilation was measured in either well watered or water stressing conditions.  Removal of heavy metals (21 different metals including Cd, Pb, Al) and particulate matter were measured in 2010 and 2011 using widely-used methods in the literature. Results indicate significant differences in CO2 uptake and pollution removal among the species compared and may provide useful information for sustainable planning of urban areas and roadside greening.

    Alessio Fini is a researcher at the Dipartimento delle Produzioni Agroalimentari e dell’Ambiente of the University of Florence. Since 2005, he has been working on projects regarding sustainable cultivation techniques for nursery production and urban forestry. These include: reduction in use of herbicides, irrigation and chemical fertilizers; effects of shading on leaf gas exchange and leaf anatomy; alternative techniques to tillage and their effects on plant physiology; effects of mulching on plant physiology and soil chemical, physical and biological properties; development of native and species-specific mycorrhiza to improve health and growth of urban trees. His PhD thesis is dealing with the mechanisms of drought tolerance of shade trees and the selection of drought tolerant species, with a particular regard to climate change. He is author of about 50 publications in international peer-reviewed journals and conference proceedings.
