“…In the shoots of C. pepo, polychlorinated biphenyls (PCBs) [17,18], polychlorinated dibenzo-p-dioxin/polychlorinated dibenzofurans (PCDDs/ PCDFs) [1], chlordane [3], and p,p 0 -dichlorodiphenyldichloroethylene (p,p 0 -DDE) [19] are detected. p,p 0 -DDE is also detected in the shoots of Cucurbita maxima, C. sativus, and Cucumis melo [19].…”

The uptake ability of hydrophobic organic chemicals by plants and the nature of xylem sap of the plants were studied. The plants were grown in soil contaminated with dieldrin. High amounts of dieldrin were detected in the shoots of Cucurbita pepo and Cucumis sativus, but little was seen in the shoots of Brassica oleracea var. italica, Solanum lycopersicum, Glycine max, Zea mays, and Helianthus annuus. The xylem saps of C. pepo and C. sativus leached dieldrin adsorbed on C8 granules, but those of the other plants did not. The xylem saps of C. pepo and C. sativus eluted high amounts of dieldrin from the size-exclusion chromatography column near the fractions of RNase A (13.7 kDa) after Aprotinin (6.5 kDa), which has a larger molecular weight than dieldrin (381). The enhancement of dieldrin solubility by xylem sap was reduced by proteinase and heating. It was suspected that the protein-like materials in the xylem sap delivered dieldrin from the roots to the shoots.

“…Final analysis of the TPH was done using Agilent 6890 Plus gas chromatograph equipped with a micro-63 Ni electron capture detector, an SPBTM-1 fused silica capillary column (30 m, 0.25 mm, ID x 0.25 μm film thickness) and HPChem station software. Data were collected in selective ion monitoring mode [15]. The injector and detection temperature was kept at 340 and 380oC respectively.…”

-The study is aimed at identifying native plants growing around petroleum hydrocarbon contaminated site in Umuahia, Nigeria that has the ability to phytoremediate the contaminant from the soil. A total of 28 native plants in the area were sampled. Most of the plants demonstrated the ability to grow in a high concentration of the total petroleum hydrocarbon which is an indication that they can be used for phytoremediation of a petroleum hydrocarbon contaminated soil. Chromolaena odorata, Aspilla africana, Chloris babata, Pasparlum vaginatum, Bryophylum pinnatum, Paspalum scrobiculatum, Spondias mombim, Euragrostis atrovilens, Cyperus rotundus, Uvaria chamae all demonstrated phytoremediation characteristics in the contaminated site. Among those characteristics was the ability to survive the toxic nature of the contamination and to uptake part of the contamination. Pearson correlation demonstrated a significant and positive relations (r = 0.64, p = 0.003) (p ˂ 0.05) between the soil and root TPH. Using bioaccumulation factor as a module for phytoremediation resulted in Linear regression between TPH concentration in the soil and root tissue of Y = 1.8696x + 608.55. From this study, chromolaena odorata, Aspilla Africana and Uvaria chamae were selected as candidate plants for phytoremediation of PAHs.

“…Zhou et al (2010) reported that the compost added into soil increased plant growth, while heavy metals accumulation in watercress demonstrated that the contents of Cd, ni, Cu, Zn, Pb and Cr in the crop were lower than the standard limitation of Chinese criteria for vegetables [15]. PCBs and PaHs are semi-volatile substances with low solubility in water and can bio-accumulate in food chain because they could absorb strongly onto organic matrices of sediment and soil [11,16]. This toxicity issue of compostamended mining residues soil is comparatively few and is rarely noticed in the practice.…”

ABSTRACT:The effects of composted sewage sludge on soil properties and vegetable quality were investigated in a field experiment for two years. The soil was amended with 3, 15 or 30 t/ha of compost. The results indicated that the vegetable net production increased with the amendment dosage of 3 and 15 t/ha, while the net production decreased in the application amount of 30 t/ha. However, the Vitamin C (Vc) content of the three vegetables was reverse. The heavy metals concentrations in vegetables and soils could meet the national food and soil environmental quality standards of China (II). The accumulation concentrations of Cd, As and Hg in the three vegetables increased with the increasing amendment dosage, while the concentrations of Cr and Pb changed significantly with different types of vegetable. Heavy metal accumulation ability was in the order of celery > lettuce > cabbage, except for Cr. The accumulation of different heavy metals in soil was related to the migration characteristic of heavy metals, plant absorption capacities and the amendment dosage. The concentration of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in the soils increased with addition of 15 t/ha and 30 t/ha, while the change was not statistically significant between the amendment of 3 t/ha and the control. The concentration of PCBs and PAHs in vegetables was positively correlated with compost addition amounts. The dissipation rate of PCBs and PAHs followed the principle of first-order kinetics, and vegetables could improve the dissipation rate. Therefore, the application of compost as soil amendment to abandoned quarries is a feasible strategy for sludge disposal because appropriate amount of compost could enhance the soil fertility, while the long-term application should be considered seriously.
