  <dc:description>&lt;p&gt;The δ&lt;sup&gt;13&lt;/sup&gt;C values of individual trihalomethanes (THM) formed on reaction of chlorine with dissolved organic carbon (DOC) leached from&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;maize&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(corn;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Zea maize L.&lt;/i&gt;) and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Scirpus acutus&lt;/i&gt;(an aquatic bulrush), and with DOC extracted from agricultural drainage waters were determined using purge and trap introduction into a gas chromatograph-combustion-isotope ratio monitoring mass spectrometer. We observed a 16.8‰ difference between the δ&lt;sup&gt;13&lt;/sup&gt;C values of THM produced from the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;maize&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Scirpus&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;leachates, similar to the isotopic difference between the whole plant materials. Both&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;maize&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Scirpus&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;formed THM 12‰ lower in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;sup&gt;13&lt;/sup&gt;C than whole plant material. We suggest that the low value of the THM relative to the whole plant material is evidence of distinct pools of THM-forming DOC, representing different biochemical types or chemical structures, and possessing different environmental reactivity.&lt;/p&gt;</dc:description>
