Heavy metals are elements that mainly have a 5-22 gr.cm-3 specific gravity. Some of these metals are essential micronutrients for plant growth (Such as Zinc (Zn), Copper (Cu), Manganese (Mn), Nickel (Ni) and Cobalt (Co)). Some other heavy metals, have a high toxicity properties such as Lead (Pb), Cadmium (Cd) and Mercury (Hg). In order to investigate the potential of watercress (Nasturtium officinale) in the uptake of elements from nutrient solutions with different salinities, a factorial experiment was conducted in a completely randomized design with three replications in the greenhouse. In this experiment, different levels of arsenic were zero, 5, 10, 20, 40, 40, 80 and 160 mg.L-1, which were obtained from sodium arsenate source and added to Epstein’s nutrient solution to obtain the mentioned concentrations. The salt concentration of the nutrient solution was 0, 10, 20, 40 and 80 mM which was prepared from sodium chloride source and added to Epstein solution. After making nutrient solutions with different salinity and concentrations, watercress was cultivated. The ANOVA results showed that the interaction of salinity and arsenic levels on the calcium, magnesium, iron, manganese, zinc and copper concentrations in watercress was significant at the level of one percent probability. The highest concentrations of these elements were obtained in the levels without salinity and arsenic and the lowest values were obtained in the 80 mM salinity levels and 160 mg.l-1 arsenic.

The common bean has been object of breeding programs aiming the development of new cultivars adapted to varied production system and shown differentiated nutritional characteristics. Due a genetic diversity existent the landraces can be used directly for cropping, for present characteristics desirable. Little information exists about mineral content and other quality traits for those bean landraces. The aim of this paper was to verify the variability for grain nutricional caracters in breeding cultivars and landraces of bean from Rio Grande do Sul state, Brazil. The experiment was conducted in 2009/2010 in Experimental Station Cascata, of Embrapa Temperate Agriculture. In whole grain of 54 bean genotypes with black and no black coat were determined macroelements (nitrogen, phosphorus, potash, calcium, magnesium and sulfur), oligoelements (iron, manganese, zinc and cuprum), protein and ash content, insoluble fiber, digestive nutrient and antioxidant astragalina. The results shown that the landraces varieties presents nutritional composition of macro and oligoelements, fibers, protein and ash contents in whole grain similar than that of breeding lines and cultivars. The black coat grain from breeding programs showed better nutritional quality for macro and oligoelements content than coloured grain, highlighting TB 02-04 e TB 01-01. The landraces with coloured grains TB 02-26, TB 02-24 and TB 03-13 showed the high levels of astragaline.

ABSTRACT Cultivation using brackish waters can result in nutritional and metabolic imbalances in several plant species, consequently reducing the production of dry matter (DM) and accumulation of toxic ions (Na+ and/or Cl-) in plants. We evaluated the DM production, and nutrient and inorganic solute (Na+ and Cl-) content in green onion plants (cv. Todo Ano Evergreen - Nebuka) under different levels of nutrient solution salinity in combination with circulation frequencies of this solution. Two experiments were conducted in a hydroponic system, using a completely randomized design, in a 6 × 2 factorial scheme, with five replicates: six levels of nutrient solution salinity (1.5, 3.0, 4.5, 6.0, 7.5, and 9.0 dS m-1) and two solution circulation frequencies (twice and thrice a day). In Experiment I, the evapotranspired depth was replaced using brackish water that was used to prepare each of the salinity levels (used exclusively), whereas in Experiment II, brackish water was used only to prepare each of the salinity levels and public water was used (electrical conductivity [ECw] = 0.12 dS m-1) for replacement in all treatments. The increase in the nutrient solution salinity reduced the production of DM and accumulation of nutrients; the reductions were more pronounced when brackish waters were used exclusively (Experiment I). However, the circulation of solutions thrice a day resulted in the harmful effects of the salinity effect. Replacing the evapotranspirated blade with water supply (Experiment II) mitigated the deleterious effects of salinity. Moreover, three circulations of the nutrient solution daily resulted in lower accumulation of inorganic Na+ and Cl- solutes and increased accumulation of nutrients N, P, K+, Ca2+, Mg2+, and S in the culture.

Pollution with heavy metals, as iron, manganese, zinc, copper, lead, nickel, and cadmium is considered for the coastal waters in two bights of Peter the Great Bay on the data of the metals content in tissues of the algae Sargassum miyabei and Saccharina japonica . The Fe and Mn indicate terrigenous runoff, the Zn and Cu - anthropogenic impact, and the Pb, Ni, and Cd are the tracers of industrial pollution. The content of Fe is the highest among heavy metals; its maximum concentrations are found in the top of the Kozmin Bay and at Cape Petrovsky in the Wrangel Bay. The Pb and Cd contents are higher at the small boats berthing in the Kozmin Bay. The Ni content is the highest (up to 4 mg/g) on reefs in front of the oil terminal in the Wrangel Bay and in the top of the Kozmin Bay that is possibly reasoned by shipping activity because Ni is included in all oils. The Zn concentration is the highest at the pier in the Wrangel Bay constructed of stone blocks. The contents of heavy metals in algae from these bights are compared with similar data from the Avachinsky Bay (Kamchatka), Nha-Trang Bay (Vietnam) and port Santos (Brazil); relatively high pollution of the Kozmin and Wrangel Bays by Pb is revealed. Pollution in these bights has mostly industrial and anthropogenic nature. The pollution with Ni and Cd decreased between 1995 and 2008, but became higher again in 2012-2013, the pollution with Mn, Zn and Fe also increased in 2012-2013.

Plants that are able to accumulate and tolerate extraordinarily high concentrations of heavy metals (hyperaccumulators) can be used for phytoremediation (removal of contaminants from soils) or phytomining (growing a crop of plants to harvest the metals). Two moss species, Bryum capillare Hedw. and Ceratodon purpureus Hedw., were tested as potential phytoremedies under in vivo conditions on a coal ash disposal site in the surroundings of Obrenovac (NW Serbia). The content of various heavy metals (iron, manganese zinc, lead, nickel, cadmium, and copper) in the mosses and substrata were investigated over a period of three years. Iron and zinc were found to have the highest concentration in the mosses.

. In this paper we present results of the measurement of some heavy metals in sheep cheese samples from three hill and alpine areas in the Banat area. We analysed, using flame and graphite furnace atomic absorption spectrometry, the following heavy metals: Fe, Mn, Zn, Cu, Co, Ni, Cr, Pb, and Cd. The concentration ranges in the cheese samples were: 7.22-8.85, 1.36-1.83, 17.39-23.17, 0.691-0.886, 0.020-0.102, 0.002-0.010, 0,214-0.225, 0.193-0.314 and 0.001-0.003 mg/kg for iron, manganese, zinc, cooper, cobalt, nickel, chromium, lead and cadmium, respectively. Analysing experimental data shows that the specific soil and climate factors in the area favour cheese assortments with normal heavy metal contents under the form of essential elements and of low concentrations of heavy metals potentially toxic or toxic much below admitted toxicity levels.

This study assessed influence of magnetized water (MW) and magnetized seed (MS) on yield and uptake of heavy metals of tomato. Tomato seeds were put on permanent magnet (1000 gauss) for 24 hours and water was allowed to flow through magnetic flux density 319 gauss. Tomato seeds (variety UC82B) were planted in 16 pots, thinned after 21 days to one tomato/pot and irrigated with MW or non-magnetized water (NMW). Four treatments used were MS and MW (T1), non-magnetized seed (NMS) and MW (T2), MS and NMW (T3), NMS and NMW (T4). A 1.0 litre of water was applied to tomato plant in a completely randomized design and each treatment was replicated 4 times. Yields and concentrations of cadmium, copper, chromium, iron, manganese, nickel, lead and zinc were determined from the tomato fruit. The mean yields for T1, T2, T3 and T4 were 288.1, 275.8, 176.6 and 200.1 g/pot, respectively. Mean concentrations of Iron for T1, T2, T3 and T4 were 0.015, 0.010, 0.010 and 0.010 mg/L, respectively. Mean concentrations of zinc for T1, T2 T3 and T4 were 0.030, 0.110, 0.115 and 0.125 mg/L. The values of copper, iron, lead, manganese and zinc for T2 were 0.02-0.03, 1.2-1.8, 0.03-0.07, 0.10-0.12 and 0.00-0.01 mg/L. The corresponding values for T4 were 0.02-0.02, 1.30-1.60, 0.04-0.04, 0.08-0.11 mg/L but Zn was not detected. Concentrations of heavy metals in the tomato were below FAO/WHO permissible limits. MW and MS increased tomato yield and didn’t increase uptake of heavy metals that could cause diseases to man.

The objective of this work was to evaluate the quality of fruits and the nutritional status of cucumber CV. Aodai cultivated in nutrient solutions with different N:K ratios. The hydroponic cultivation was initially performed, during the vegetative growth, in nutrient solution with 1:2.0 mmol L-1 N:K, and, later, during fruit setting, in four different nutrient solutions with N:K (w/w) at the ratios 1:1.4, 1:1.7, 1:2.0 and 1:2.5. An additional treatment with a nutrient solution containing the ratio 1:2.2 (w/w) N:K during the vegetative growth and N:K 1:1.4 (w/w) during fruit setting, both with 10% ammonium (NH4+) was included. The treatments were arranged in a randomized design with six replicates. Irrigation was carried out with deionized water until seed germination, and then with nutrient solution until 30 days after germination, when plants were transplanted. Plants in the hydroponic growing beds were irrigated with the solutions for vegetative growth, and, after 21 days, the solutions were replaced by solutions for fruit setting. At 45 and 60 days after transplanting, the fresh weight, length, diameter, volume and firmness of the fruit were evaluated, and, at 45 days after transplanting, the macronutrient concentrations in the leaves were determined. The use of different N:K ratios during fruit setting influenced the cucumber production. The ratio of 1.0:1.7 N: K (w/w), with 10% of N in the form of ammonia, is recommended for the whole cycle.

Bagasse was milled into small size of 0.200152 mm volume surface mean diameter. The powder was found to be a rich source of many macro and micro nutrients, namely Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulphur, Iron, Manganese, Zinc, and Copper. FTIR spectrum indicates the possible presence of polysaccharides like cellulose, lignin and hemicelluloses, and polyphenols in the bagasse sample. Micro-images of the bagasse obtained through SEM shows the features of fiber structures. The fiber cells are cross-linked and surface seems to be rough and thick-walled. The fiber pith was found to have pits at some places. Proximate analysis through EDX shows the high proportions of Carbon (44.51%) and Oxygen (55.49%).

The iron content in gametophytes of <i>Aulacomnium palustre. Climacium dendroides, Catharinea undulata</i> is 5—10 times higher than in vascular plants. The manganese, zine and copper content is 2-3 times higher than in vascular plants. The content of these elements in sporophytes of <i>Catharinea undulata</i> is approximately the same as in vascular plants. The accumulation of the investigated metals takes place mainly in the protoplasts of the chlorophyll cells of gametophyte leaves. A weakly acid pH of the medium favors accumulation. No distinct difference was found between the Fe<sub>2</sub>O<sub>3</sub> content in mosses and the soil.
