Abstract: | Urban expansion into traditional agricultural lands has augmented the potential for heavy metal contamination of soils. This
study examined the utility of field portable X-ray fluorescence (PXRF) spectrometry for evaluating the environmental quality
of sugarcane fields near two industrial complexes in Louisiana, USA. Results indicated that PXRF provided quality results
of heavy metal levels comparable to traditional laboratory analysis. When coupled with global positioning system technology,
the use of PXRF allows for on-site interpolation of heavy metal levels in a matter of minutes. Field portable XRF was shown
to be an effective tool for rapid assessment of heavy metals in soils of peri-urban agricultural areas. |
