“…Djingova, et al, 1987;Haritonidis & Nikolaidis, 1989, 1990. At Antikyra Gulf (Viotia, Greece), some investigations on the bioaccumulation of metals by seagrasses were carried out (Malea, 1994;.…”

An analysis was made of the levels of Fe, Cu, Zn, Cd, Pb, Na, K, Ca and Mg in three green and four brown seaweeds, abundant in the Antikyra Gulf (Viotia, Greece). After Ca and the macroelements K, Mg, Na, the higher concentrations found were of Fe and Pb, with Fe>Pb. Cadmium content was low in most species. Differences between species and taxonomic groups were also considered. Fe, Zn, Cd and Ca in the green alga Dasycladus vermicularis increased from March to July and had their maxima in summer or autumn (Cd), whereas Cu, Pb and Mg showed an opposite pattern of seasonal variation with maxima in winter. Cu, Zn, Cd and K in D. vermicularis were correlated with their concentrations in the sediment and not with their dissolved levels in seawater. Iron in D. vermicularis was positively correlated with Zn and negatively with Cd.

“…The usual practice, however, is to combine the analytical techniques whenever possible instead of optimizing the analysis to reach high performance. A typical combination is INAA and AAS (71,164,165) to overcome the inability of INAA to determine lead and the difficulties in determining Cd and Cu. At present the practice is the combination of the two ICP techniques: ICP-AES for determination of macroelements and macronutrients and ICP-MS for trace elements and micronutrients (2,4,27,(166)(167)(168)(169).…”

The study of the ionome (ionomics) is defined as quantitative and simultaneous measurement of the element composition of living organisms and changes in this composition in response to physiological stimuli, development stage, and genetic modifications (Salt et al., Ann. Rev. Plant Biol., Vol. 59, 2008). The necessity of understanding the regulation processes of elements in the organisms demands determination of many elements in the organism, tissue, and cell (Baxter, Plant Biol., Vol. 12, 2009) . A prospect for ionomics is environmental pollution where great variety of conditions and pollutants exist resulting in concentration and interelemental changes in the plant ionome. The capabilities of and problems with several multielement analytical techniques, including instrumental neutron activation analysis (INAA), X-ray fluorescence, inductively coupled plasma-atomic emission spectrometry (ICP-AES), inductively coupled plasma-mass spectrometry (ICP-MS), and atomic absorption spectrometry (AAS), which are adequate and most promising in ionomic and environmental studies of plants, are reviewed. References are confined mainly to the last 10-15 years. Information about concentrations, roles, binding forms, and pollution sources of the elements and comparison between methods with respect to limits of detection, determined elements, interferences, and economic considerations are tabulated. Some combinations of instrumental techniques supplementing each other are highly valued, namely, ICP-MS and ICP-AES and INAA and AAS or ICP-AES.

“…Although plants require heavy metals for development and maintenance, excessive quantities can be poisonous. Plants' capacity to gather critical metals also allows them to acquire non-essential metals (Djingova & Kuleff, 2000). Since metals cannot be broken down, when their concentrations inside the plant reach ideal levels, they hurt the plant both directly and indirectly.…”

Heavy metal-polluted soils have grown ubiquitous worldwide due to increased geologic and anthropogenic activity, and the plants growing in these soils exhibit decreased growth, performance, and yield. Contaminated soil with heavy metals has become a concern for agricultural scientists because of the progress made in agricultural product safety. Heavy metals are metalloids with biological toxicity. The most common are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn). These metals exist throughout the terrestrial environment and have spread out due to anthropogenic and natural activities. Soil heavy metal pollution leads to human health risks, groundwater pollution, plant phytotoxicity, and a decline in crop and soil production. Bioremediation is an effective method of treating heavy metal-polluted soils. It is a widely accepted method that is mostly carried out in situ; hence it is suitable for the establishment/reestablishment of crops on treated soils. Using plants in the treatment of polluted soils is a more common approach in the bioremediation of heavy metal-polluted soils. Bioremediation ensures a more efficient clean-up of heavy metal-polluted soils. However, the success of this approach largely depends on the species of organisms. This paper is aimed to review the hazardous effects of heavy metal toxicity on soil and plants and their bioremediation. This paper also discusses numerous strategies for addressing heavy metal contamination in soil. Keywords: heavy metals, anthropogenic sources, natural sources, bioremediation
