“…Site B, which was the active dumping receptacle at the time of sampling had high levels of Cu, Zn, Pb, Ni and Cd. This may be due to inputs of heterogeneous waste at the site, which would have had the least period of metal export from the soil via processes such as uptake by plants growing in the http://www.publish.csiro.au/journals/spjnas area (Borghei et al, 2011). Based on the data obtained, we suggest that in the Lami disposal site, heterogeneous waste dumping has been a larger source of heavy metals than that present in the soil from its parent material.…”

We report the first screening study for the metals copper, zinc, lead, nickel and cadmium in the Lami municipal disposal facility, in Suva, Fiji where virtually uncontrolled dumping has been carried out for over fifty years. Soil from three parts of the facility having had different degrees of usage was analysed for a range of heavy metals, and evaluated according to international guidelines. The results show copper (100–220 mg kg–1), lead (200–500 mg kg–1) and zinc (220–350 mg kg–1) concentrations exceeded commonly used eco-toxicity threshold values (copper, 160 mg kg–1; lead, 210 mg kg–1; and zinc, 220 mg kg–1). Moreover, there were indications that considerable leaching may have been occurring for long periods of time at the site. Overall, this study shows that even in areas with little industrialization, lack of adequate waste management controls can result in unusually high levels of contamination. The results raise concerns about the wellbeing of the communities living adjacent to the facility that depend on the adjacent marine environment for subsistence.

“…It was observed that the growth of root and shoot along with their relative water content was not affected at 25 mg•L −1 of Cs in Sesuvium. In Calendula alata, Borghei et al [36] observed maintenance of plant growth, root length, shoot length, and chlorophyll contents lower concentrations up to 10 mg•L −1 Cs but beyond this concentration, growth was retarded. Higher Cs concentration (3 M Cs) also showed a reduction in shoot growth in the Cs hyper-accumulator Pennisetum purpureum [10].…”

Cesium (Cs) is a soil contaminant and toxic to the ecosystem, especially the plant species. In this study, we have assessed the potential of a halophyte Sesuvium portulacastrum for its Cs tolerance and accumulation. Thirty days old S. portulacastrum plants were subjected to different concentrations of Cs (0, 5, 10, 25, 50, and 150 mg·L−1 Cs) using cesium chloride. The biomass and photosynthetic pigments were not affected up to 25 mg·L−1 Cs treatment while a significant decline in pigment levels was observed at higher concentrations. The Cs treatments increased protein content at low concentrations while higher concentrations were inhibitory. Under Cs exposure, significant induction of antioxidant enzymes such as ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), and superoxide dismutase (SOD) was observed. The antioxidant enzyme activities were upregulated up to 50 mg·L−1 Cs but decreased significantly at 150 mg·L−1. The accumulation of Cs was dose and tissue-dependent as evidenced by a higher accumulation of Cs in leaves (536.10 μg·g−1) as compared to stem (413.74 μg·g−1) and roots (284.69 μg·g−1). The results suggest that S. portulacastrum is a hyper-accumulator of Cs and could be useful for the phytoremediation of Cs-contaminated soils.

“…The biomass produced by cock's comb was highest followed by sunflower and marigold which indicates to cock's comb being best for phytoremediation. Borghei et al [21] evaluated "the potential of Calendula alata for phytoremediation of stable Cesium and Lead from solutions and reported that it was more suitable for Lead phytoremediation than Cesium". "Irrigation of flower crops with tannery effluent water resulted in considerable amount of Cr accumulation in J.sambac, J.grandiflorum, P.tuberosa and N.oleander was examined.…”

Soil contamination has become a serious problem in many industrialized and developing countries. Indiscriminate dumping of urban and industrial effluents along with solid waste often lead to toxic accumulation of heavy metal ions which not only impair soil productivity but also cause health hazards by entering into food chain via soil-plant-animal/human route. With rapid urbanization and industrialization, large quantities of industrial effluents get mixed with sewage and river water [1]. Irrigating crop fields with such contaminated sewage water is being increasingly adopted by marginal farmers due to scarcity of irrigation water. It also inadvertently leads to addition of large quantity of heavy metals to the agro ecosystem [2]. Plants with abilities to hyperaccumulate, accumulate, exclude and indicate heavy metals are important in environmental remediation. Most phytoremediation studies are aimed at inorganic pollutants through different approaches defined as phytoextraction (the used of metal accumulating plants to transport and concentrate metals from the soil to roots and above ground biomass), rhizofiltration (the use of plant roots to absorb, precipitate, and concentrate toxic metals from polluted effluents), and phytostabilization (the use of plants to reduce the mobility of metals)
