Abstract
This field study aimed to assess the base line conditions of a long-term polluted shooting range in Argentina polluted with 428 mg kg-1 lead (Pb), to evaluate the establishment and development of Helianthus petiolaris plants and address the efficacy of the phytomanagement strategy through: i) element accumulation in plant tissues; ii) rhizosphere bacterial diversity changes by Illumina Miseq™ and iii) floral water and essential oil yield, composition and element concentration by GC-MS and ICP. After one life cycle growing in the polluted sites, in the roots of Helianthus petiolaris plants Pb concentration was between 195 and 304 mg kg-1 Pb. Only a limited fraction of the Pb was translocated to the aerial parts. The predominance of the genus Serratia in the rhizosphere of Helianthus petiolaris plants cultivated in the polluted sites and the decrees of the essential oil yield were some effects significantly associated with soil Pb concentration. No detectable Pb concentration was found in the floral water and essential oil obtained. Extractable Pb concentration in the soil reduced between 28-45 % after the harvest.
