“…Similarly, Warncke et al (2002) and Park et al (2004) observed that although lime application increased calcium and magnesium concentrations in the soil, it had no effect on the elemental composition of asparagus fern and willow, respectively. In our study, the magnesium levels in sugar cane were considerably lower than the total levels measured in agricultural soil such as De Nicola et al (2003) measured for Holm oak leaves. Contrarily, Materechera (1999) estimated a higher correlation between the calcium and magnesium levels in wheat seedlings compared to corresponding levels in soil from South Africa (r = 0.830, r = 0.790, respectively).…”

This investigation was initiated to assess the following objectives: (1) to measure the total calcium and magnesium content in agricultural soil and sewage sludge from the Mediterranean coastal area of Motril (southeastern Spain); (2) to determine the pH values of indicated samples in order to IntroductionCalcium is readily evident in alkaline soil and is very scarce in very acidic silicon soil. Weathering and rainfall in the area has a large impact on the chemical composition and calcium levels in the surrounding soil. In soil from arid or semiarid zones, high calcium concentrations have been found (Ganor and Mamame, 1982; Löye-Pilot et al., 1986;Young et al., 1988). Lower levels of acidity, less rainfall, and therefore less erosion, enhance the stability of minerals like the calcium in the soil's clay. As a result, the high calcium content will tend to flocculate in the upper profile of the soil's clay (Ruhe, 1984). Phillips and Chiy (2002), after applying sodium fertilizers, observed an enhancement of calcium concentrations in leachate. Similarly, an increase in calcium, magnesium, and pH values was observed in tropical agricultural soil after applying compost (Slattery et al., 2002;Soumare et al., 2003).In soil, magnesium is present mainly in inorganic compounds, although considerable amounts also appear associated with the organic material in humus (Sutcliffe and Baker, 1983). It is known that the principal portion of exchangeable magnesium is associated with clay particles. Exhaustion of the soluble magnesium cation in the soil by microorganisms and the plant's roots provokes uptake of the solid (non-soluble) mineral, which affects the nonexchangeable fraction. On the other hand, when the soil's acidity increases, a diminishment of available magnesium is observed due to the fact that hydrogen ions occupy a high number of the exchange sites (Sutcliffe and Baker, 1983). Studies indicate that in coastal areas magnesium enters the atmosphere from the sea because this element is one of the main constituents of marine aerosols.It is known that magnesium uptake by plants is affected by the presence of other cations such as ammonium, potassium, manganese, and sulphur (Pessarakli, 1995; Phillips and Chiy, 2002). For high levels of pH, the ratios of Mg/Ca, Mg/K and Mg/Al, rather than the magnesium concentration alone, are related to the element flux in plants (Rengel and Robinson, 1990).The existence of calcium and magnesium in soil is related to several factors, including geographic location, type of rock, pH, nature of drainage water, clay content, cation exchange capacity, weathering and climatic conditions, and type of plant grown (Young et al.,

“…Lead is one of the elements which have a very low translocation from soil to leaves (De Nicola et al 2003). This means that if the soil has a great availability of lead, the plant leaves which grow on that area might not have availability of lead at all, or they might have a much smaller concentration compared with that of the soil.…”

Concentrations of chromium, copper, and lead were determined in soil and plant specimens collected from the area of coal power plant (CPP), A. Dimitrios, the largest CPP in Greece located on the eastern part of Ptolemais basin, Macedonia. Two cultivated plants (Brassica oleracea var. capitata L. and Zea mays L.) and two non-cultivated plants (Rumex acetosa L. and Verbascum phlomoides L.) were chosen. The mean heavy metal content in the soil is described in the descending order of Cr>Pb>Cu, while for the plant material, the order was Cr>Cu>Pb. Stations in the vicinity of the CPP showed a distinctly high load of Cr in the soil, whereas for the other metals, no such correlation has been noted. Unexpectedly, high levels of chromium and copper have been found in plant samples of the control station (Grevena) where there is no significant point source of air pollution by particulate matter. In general, roots revealed a higher metal concentration than that of the other plant organs. This is more obvious in B. oleracea var. capitata for all metals studied. Thus, B. oleracea var. capitata possesses the potential for phytoremediation of soils contaminated by metals since this plant is removable together with its roots from the contaminated soil. The most contaminated leaves showed a variation in surface roughness. In V. phlomoides the non-glandular, branched candelabrum-like trichomes on the leaf epidermis effectively trapped and retained a considerable number of particles. In contrast, the waxy cuticle of R. acetosa, which forms a smooth sheet over the epidermal cells, enabled the fast removal of particles by rain or wind. In the case of Z. mays, seeds accumulated the lowest amount of all metals.

“…The low ratio values for Pb, Cd and Cu, accompanied with their high availabilities in soils indicated low Pb, Cd and Cu translocation from soils to needles. De Nicola et al (2003) ascribed the limited Cd and Pb mobility to the elements being blocked immediately after absorption. On the other hand, the high ratio between needle Zn and available soil Zn concentrations, together with its low soil availability suggested that high Zn translocation occurred from soils to needles.…”

Current (C) and previous year (C + 1) needles and soils (organic horizon, 0-10 cm and 10-20 cm mineral depth) of Masson pine (Pinus massoniana L.) trees were sampled at four forested sites (Huang Pu industrial district, HP; South China Botanical Garden, BG; Mao Feng Mt., MF; and Nan Kun Mt., NK) in Guangzhou along a urban-rural gradient and analyzed for sulfur (S) and heavy metals (Cu, Zn, Ni, Cd, Cr and Pb) concentrations. Needle concentrations of all the elements were significantly higher at industrial HP than at other three sites, except for Cu and Pb which were highest at the traffic site (BG). The C + 1 needles generally had higher Cu, Cd, Pb, Zn, Cr than the C needles while the opposite was for Ni and S. Total and available Cd, Pb, Zn in soils peaked at the urban sites (HP and BG) and decreased at suburban MF and rural NK. Heavy metals were generally higher in the organic soils than in the mineral soils at all sites. Zinc and Pb at all sites, and Cd, S and Cu at the urban sites (HP and BG) in soils or pine needles were above or near their respective natural background levels, implying that threats resulted from these toxic elements occurred on local particularly urban forests, but did not for Cr and Ni due to their presence below their background values. Our results demonstrated that elements concentrations in needles and soils had reflected the variability of pollutants and the environmental quality change along the urban-rural transect, and were efficient as biomonitors to assess the influence of anthropogenic activities along the urbanization course on forest health.
