Title: | Chemically assisted phytoextraction: A review of potential soil amendments for increasing plant uptake of heavy metals | Authors: | MEERS, Erik Tack, Filip M. G. Van Slycken, Stijn RUTTENS, Ann Du Laing, Gijs VANGRONSVELD, Jaco Verloo, Marc G. |
Issue Date: | 2008 | Publisher: | TAYLOR & FRANCIS INC | Source: | INTERNATIONAL JOURNAL OF PHYTOREMEDIATION, 10(5). p. 390-414 | Abstract: | The contamination of soils by trace metals has been an unfortunate sideeffect of industrialization. Some of these contaminants can interfere with vulnerable enduses of soil, such as agriculture or nature, already at relatively low levels of contamination. Reversely, conventional civil-technical soil-remediation techniques are too expensive to remediate extended areas of moderately contaminated soil. Phytoextraction has been proposed as a more economic complementary approach to deal with this specific niche of soil contamination. However, phytoextraction has been shown to be a slow-working process due to the low amounts of metals that can be annually removed from the soil under normal agronomic conditions. Therefore, extensive research has been conducted on process optimization by means of chemically improving plant availability and the uptake of heavy metals. A wide range of potential amendments has been proposed in the literature, with considerable attention being spent on aminopolycarboxylic acids such as ethylenediaminetetraacetic acid (EDTA). However, these compounds have received increasing criticism due to their environmental persistence and associated risks for leaching. This review presents an overview of potential soil amendments that can be employed for enhancing metal uptake by phytoextraction crops, with a distinct focus on more degradable alternatives to persistent compounds such as EDTA. | Notes: | [Meers, E.; Tack, F.
