Spectral data were collected for each of five replicates prior to harvest at 4-week intervals. Fern samples were analyzed for total metals content and Partial Least Squares and Stepwise Linear Regression techniques were used to develop models from the spectral data. Results showed that&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;Pteris cretica mayii&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="html-italic"&gt;Pteris multifida&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;are confirmed hyperaccumulators of inorganic arsenic and that reasonably accurate predictive models of arsenic concentration can be developed from the first derivative of spectral reflectance of the hyperaccumulating&amp;nbsp;&lt;/span&gt;&lt;span class="html-italic"&gt;&lt;i&gt;Pteris&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;ferns. Both the arsenic uptake and spectral results indicate that there is some species-specific variability but the results compare favorably with previously published data and additional research is recommended.&lt;/span&gt;&lt;/div&gt;</dc:description>
