Formatted abstract
The potential use of Magnolia grandiflora for phytomonitoring trichloroethylene (TCE) and tetrachloroethylene (PCE) contamination in groundwater was studied. Four replicate tree samples with one control (without TCE and PCE treatment) were planted in growth chambers from April to June, 2013. Tree cores were sampled and extracted employing Headspace-solid phase microextraction at 25oC for 10mins. Both qualitative and quantitative test of the target compounds was done using Gas chromatograph Mass Spectrometer. Statistical analysis was performed using SPSS (Statistical significance was accepted at a=0.05). The results showed that the experimental period (April to June) favored the compounds because of its enhanced transpiration rate during the period. The concentration of TCE at the initial stages of the experiment were significantly higher than PCE but this changed with time (P<0.5). Meanwhile, there was no consistency in the measured concentrations of both compounds at the various heights along the tree (10, 30, 50cm) as was expected. Notably, there was no indication of VOC toxicity to the plants. It is therefore concluded that Magnolia grandiflora can be employed in phytomonitoring TCE and PCE in groundwater. The results from the study provides essential and relevant information for policy makers and other environmentalists. This is a new finding and as far as the authors are aware, this is the first manuscript that has understudied this and hence, this study is of great benefit for the efficient management of groundwater resources.
