Figure 1: Number of publications from 1990 to 2012 using the key words PubMed(control), phytoremediation, and phytoremediation+cytochrome P450 (CYP). Left Y-axis represents number of publications for PubMed and phytoremediation and right Y-axis represents number of publications for phytoremediation + cytochrome P450. The control showed a slow increase in number of publications from 1990 to 2000, followed by a rapid increase in publications until 2011. Phytoremediation and CYP-mediated phytoremediation showed similar trend until 2009, however, there was a decline inthe number of publications from 2009 to 2011. As expected, all three showed less number of publications in 2012 (until August 15), however, the trends suggest that there would be a further increase in PubMed publications, but a decrease in the number of publications for phytoremediation and CYPbased phytoremediation.
