Abstract
  • The aim of this study was to investigate the phytoremediation capacity of fast growing trees (Populus and Salix spp.) in an industrial site. The study area is an artificial island (Isola dei Petroli, in Venice lagoon) built using different materials, including oil-refinery by-products. Tests were carried out in an experimental field measuring 40 x80 m3. Half of this field was planted with trees, a quarter with fern and the last quarter used as control. Two clones of Populus deltoides (Dvina, Lena), one of P.xcanadensis (Neva), two Salix matsudana (S76-005 and S76-008), and one of Salix alba (SI64-017) were planted in the experimental area in a randomized block design with four replications at a commonly used density in Short Rotation Coppice (6000 plants/ha). Aims of the plantation of forest trees were immobilisation and extraction of As, Pb, Zn, and Cd present in large amount in this site, but also the maintenance and improvement the hydrological balance of the site. In fact, since the island has been completely separated from the surrounding sea by an artificial barrier to avoid contamination, rainfall water has either to be cycled back to the atmosphere via evapotranspiration or to be pumped away. Then, poplar and willows trees can be very useful to remove excess water from soil, being these species characterised for an elevated water consumption. The concentration of Arsenic and some heavy metals (Cd, Zn, Pb) were measured in soil, in groundwater, interstitial water and in plant samples. In addition to poplar and willows, the most important indigenous plants were also analysed. Moreover, to evaluate the plantation efficiency in controlling the hydrological balance, the site was equipped with meteorological sensors (weather station) to assess the main parameters of causing and driving the hydrological cycle, including tree transpiration, thet was measured using the heat pulse technique with Granier sensors. After three years among the examined clones, all poplars showed higher tolerance to soil and water contaminants with respect to willow spp. Poplars showed higher metal contents in all organs. a good correlation was found between clones with higher transpiration rates and biomass accumulation and heavy metal concentration in the plant organs. The plantation, that currently is 4 years old, proved to be efficient in regulating the hydrological balance in spring and summer, when practically all rainfull was transpired, even in years with relatively \"humid\" summers. Furthermore, following summer thunderstorms, soil water status under the plantation was more rapidly restored compared to control plots. (literal)
