Mercury uptake and effects on growth in Jatropha curcas

Journal of Environmental Sciences 2016年第10期28卷 120-125页

作者： jose Marrugo-Negrete jose Durango-Hernandez jose Pinedo-Hernandez German Enamorado-Montes Sergi Diez University of Cordoba Faculty of Basic Sciences Department of Chemistry Water Applied and Environmental Chemistry Group Monteria Colombia Environmental Chemistry Department Institute of Environmental Assessment and Water Research ID█A-CSIC E-08034 Barcelona Spain

The use of metal-accumulating plants for the phytoremediation of contaminated soils is gaining more attention. Mercury （Hg）-contaminated soils from historical gold mines represent a potential risk to human health and the environment. Therefore, Jatropha curcas plant, that has shown its tolerance to these environments, is a species of particular interest to implement phytoremediation techniques in gold mining sites. In this work, the behavior of J. curcas was assessed in different hydroponic cultures fortified with Hg at concentrations of 5, 10, 20, 40, and 80μg Hg/mL （T5, T10, T20, T40 and T80, respectively）. After exposure, plant growth, net photosynthesis, leaf area, and Hg accumulation were determined and variables such as net Hg uptake, effective Hg accumulation, translocation and bioaccumu- lation factors were calculated. Accumulation of Hg in root and leaf tissues increased with respect to the Hg concentrations in the hydroponic culture, with statistically significant differences （p 〈 0.05） among treatments. Moreover, Hg concentration in roots was 7 and 12-fold higher in average than in plant leaves and shoots, respectively. Many effects were found in the development of plants, especially related with loss of biomass and leaf area, with significant growth inhibition related to control values （〉50% with treatment T5）. Moreover, percentage of inhibition was even higher （〉60%） with same treatment for net photosynthesis. Finally, it should be highlighted that for T40 and T80 treatments, plant growth and photosynthesis were almost completely depleted （88%-95%）.
