“…2.a). Total dissolved Cu concentrations in the SPW increased in 2010 and 2011 linearly with total soil Cu (R² > 0.9) confirming previous findings (Hattab et al, 2015). This agreed with Gonzalez et al (2014), Kolbas et al (2011) and Salati et al (2010) who tested the efficiency of phytoextraction to reduce Cu excess in the soil pore water.…”

Copper-contaminated soils were managed with aided phytoextraction in 31 field plots at a former wood preservation site, using a single incorporation of compost (OM) and dolomitic limestone (DL) followed by a crop rotation with tobacco and sunflower. Six amended plots, with increasing total soil Cu, and one unamended plot were selected together with a control uncontaminated plot. The mobility and phytoavailability of Cu, Zn, Cr and As were investigated after 2 and 3 years in soil samples collected in these eight plots. Total Cu, Zn, Cr and As concentrations were determined in the soil pore water (SPW) and available soil Cu and Zn fractions by DGT. The Cu, Zn, Cr and As phytoavailability was characterized by growing dwarf beans on potted soils and determining the biomass of their plant parts and their foliar ionome. Total Cu concentrations in the SPW increased with total soil Cu. Total Cu, Zn, Cr and As concentrations in the SPW decreased in year 3 as compared to year 2, likely due to annual shoot removals by the plants and the lixiviation. Available soil Cu and Zn fractions also declined in year 3. The Cu, Zn, Cr and As phytoavailability, assessed by their concentration and mineral mass in the primary leaves of beans, was reduced in year 3.

Industry sector exerts a negative effect on the environment. Industrial waste is often disposed to the rivers. The industry contributes to the accumulation of heavy metals in the environment. In farming sector, the accumulation of heavy metals can result in water pollution and be washed into the ground. Therefore, the farming product can be contaminated with heavy metals and they can be harmful to human health. The objective of this research was to reduce the Pb heavy metal content in paddy soil. This research was taken place in the Pb contaminated paddy soil using a randomized complete block design with three factors and three replicates. This research employed combination of inorganic fertilizer, ramie and Agrobacterium sp. I 3 or compost as a chelator to improve Pb uptake. The results showed that combination of the three treatments increased Pb uptake. The combination of chemical fertilizers, ramie with compost increased the Pb uptake of 11.93 μg/g or 45.9%. The combination of chemical fertilizers, ramie with Agrobacterium sp. I 3 resulted in the highest Pb uptake of 12.85 μg/g or 49.8%. The combination also decreased the soil Pb level by 7.8 μg/g or 23.5% of the control.

“…In the restoration of contaminated soils, the use of organic amendments is widespread (Ciadamidaro et al, 2015;Hattab et al, 2015;Montiel-Rozas et al, 2015) but the effect of them on LMWOA exudate by roots has been scarcely studied. A few previous studies have reported the increase of LMWOAs release in soil solution due to the amendment addition (Peña et al, 2015).…”

Bioavailability of heavy metals can be modified by different root exudates. Among them, low molecular weight organic acids (LMWOAs) play an important role in this process. Three plant species (Poa annua, Medicago polymorpha and Malva sylvestris), potentially used for phytoremediation, have been assessed for both metal uptake and LMWOAs excretion in contaminated environments with different concentrations of Cd, Cu and Zn. The experiments have been carried out in washed sand and in three contaminated soils where two organic amendments were added (biosolid compost and alperujo compost). The most abundant LMWOAs excreted by all studied plants were oxalic and malic acids, although citric and fumaric acids were also detected. The general tendency was that plants responded to an increase of heavy metal stress releasing higher amounts of LMWOAs. This is an efficient exclusion mechanism reducing the metal uptake and allowing the plant growth at high levels of contamination. In the experiment using wash sand as substrate, the organic acids composition and quantity depended mainly on plant species and metal contamination. M. polymorpha was the species that released the highest concentrations of LMWOAs, both in sand and in soils with no amendment addition, whereas a decrease of these acids was observed with the addition of amendments. Our results established a clear effect of organic matter on the composition and total amount of LMWOAs released. The increase of organic matter and nutrients, through amendments, improved the soil quality reducing phytotoxicity. As a result, organic acids exudates decreased and were solely composed of oxalic acid (except for M. polymorpha). The release of LMWOAs has proved to be an important mechanism against heavy metal stress, unique to each species and modifiable by means of organic amendment addition.
