The importance of nickel (Ni) in the environment is an issue that is gaining broader recognition. While nickel is an element essential for plants, it is also a heavy metal. Nickel is a component of nine metalloenzymes, including urease, which participates in urea hydrolysis. It also helps some plants to protect themselves against pathogens and herbivorous insects. There are many sources of Ni in the environment, which can be a problem because at higher concentrations this element is toxic to plants and other living organisms. Therefore, standards have been defined for the Ni content in air, water, soil and plants. Its content is monitored in the air. More and more frequently, attention is paid to this element as an allergen in humans. In the world, attempts have been made to phytoextract nickel from contaminated soils using nickelphilous plants, the so-called hyperaccumulators, and even to recover the metal from these plants by so-called phytomining. On the other hand, nickel-containing fertilizers are marketed and used in cases of nickel deficiency in plants. In industry, this element is primarily used for the production of steel and alloys. The most recent application of nickel is related to graphene, which was invented 10 years ago. Although nickel contamination does not occur in Poland, we cannot rule out this risk in the future. Thus, it is important to monitor the fate of nickel in the environment.

The objective was to identify the main factors influencing micronutrient policies in the opinion of policy actors in ten European countries. Study was carried out during Jan-Nov 2010 in European countries: the Czech Republic, Denmark, England, Germany, Greece, Italy, the Netherlands, Norway, Poland and Spain. Semi-structured qualitative interviews were conducted with representatives of stakeholders involved in the vitamin D, folate and iodine policy making process. Fifty eight key informants representing mainly scientific advisory bodies (n=24) and governmental organisations (n=19) participated in the study. The remaining interviewees represented non-governmental organisations (n=6), industry (n=4) or were independent academic or health professional experts (n=5). Data were analysed by theoretical interpretative thematic analysis. Insights from interviewees on the development of micronutrient policies were grouped using the Public Health Nutrition Policy-making model. The main factors influencing the micronutrient policies were: systematic monitoring of nutrition and health, causal relationships between consumers' diet-related behaviours and health outcomes, scientific recommendations from national bodies (Science area); scientific recommendations from international authorities and experiences of other countries, EU legislation, cultural factors (Wider context) and political environment, national capacity to deal with the problem, national legislation, economics, stakeholder engagement, relationships between stakeholders (Policy and institutions area). The spectrum and weight of the factors influencing nutritional policy depends on nutrient, country and degree of its "advanced status" within nutrition policy, political environment, culture and socio-economic conditions as well as the point of view (who is expressing the opinion).

In this study we determined the levels of trace elements (zinc, copper, lead, cadmium and mercury) in three layers of bones of the hip joint (cartilage, compact bone and spongy bone) of 30 red foxes (Vulpes vulpes) from north-western Poland. Concentrations of Cu, Zn, Pb and Cd were determined by atomic absorption spectrophotometry (ICP-AES) in inductively coupled argon plasma using a Perkin-Elmer Optima 2000 DV. Determination of Hg concentration was performed by atomic absorption spectroscopy. In cartilage, compact bone and spongy bone samples from the red fox, median concentrations of the metals studied could be arranged in the following descending series: Zn > Cu > Pb > Cd > Hg, the values ranging from 142 to 0.002 mg/kg dw. There was a significant difference in Cu concentrations, among all the materials analyzed, with much more Cu found in spongy bone than in compact bone. Significant differences were also noted in the case of Hg concentrations in cartilage with compact bone and the spongy bone, and between concentrations of this metal in compact bone and spongy bone. In males, the concentration of Hg in spongy bone was greater than in females. Younger foxes had a higher concentration of this metal in cartilage than adults. The strongest synergistic relationships were observed in spongy bone between the Zn and Cu, Zn and Cd, as well as between Cu and Cd. Statistically significant antagonistic relationships were detected between zinc and lead in compact bone. In addition to monitoring studies conducted on the abiotic environment, an urgent need exists for long-term monitoring of concentrations of heavy metals with long-term effects on living organisms. An important addition is provided by biomonitoring studies on domesticated and free-living mammals, including Canidae.

Our objective was to determine the content of macro- and micronutrients, toxic heavy metals as well as total phenols in 10 broccoli (Brassica oleracea var. italica) cultivars. The experiment was designed at the Poznań University of Life Sciences, Poland, and completed during two plant growing seasons. Broccoli seedlings were planted in a field in early July and the plants were harvested between September and October. The content of general forms of nitrogen was measured by distillation with the Kjeldahl method. The content of potassium, calcium and sodium was assessed by flame photometry, and the content of magnesium, cadmium, lead, nickel, copper, zinc, manganese and iron was determined by flame atomic absorption spectroscopy (FAAS). The content of heavy metals, macronutrients and sodium in the broccoli heads depended on a cultivar. Having analyzed the levels of macronutrients in ten broccoli cultivars, it was concluded that cv. Agassi and Tradition had the highest content of nitrogen and phosphorus. A very high amount of phosphorus was also found in cv. Beaumont. The highest concentrations of calcium and potassium were found in cv. Monte Carlo. The cultivars Agassi, Beaumont, Tiburon and Tradition were characterized by the highest content of magnesium. The highest content of sodium occurred in the cultivars Beaumont and Monopoly. With respect to micronutrients, the highest content of iron, copper, zinc and manganese was revealed in cv. Agassi. The highest content of nickel was determined in the cultivars Beaumont and Monte Carlo. In addition, the cultivar Monte Carlo was characterized by the highest content of lead, and Beaumont had the highest content of cadmium. However, the maximum permissible levels of cadmium and lead were not exceeded in the heads of the ten broccoli cultivars. In both years of the study, the highest content of phenols was found in cv. Steel and the lowest one appeared in cv. Agassi.

In 1996, a field experiment was set up on class IIIa soil, which consisted of 6 trials: 1 – bare fallow, 2 – fallow land seeded with annual plants, 3 – field swarded with goat’s rue (Galega orientalis Lam.), 4 – traditional fallow, 5 – field swarded with a mix of goat’s rue (Galega orientalis Lam.) and aweless brome (Bromus inermis), 6 – field swarded with aweless brome (Bromus inermis). During the tests, no agrotechnical measures were carried out apart from periodical mechanical weeding of the bare fallow and the sowing of annual plants. Plant samples for chemical analyses were taken from the swarded fields; the remaining biomass was left on the fields. After each growing season, soil samples were collected in four replicates from the 0-25 cm and 25-50 cm soil horizons, for determination of the content of Cu, Zn and Mn available forms. This paper discusses the results obtained in 2000-2007. The experiment has demonstrated that the way farmland was laid fallow or set-aside had an effect on concentrations of the available forms of Cu, Zn and Mn in the 0-25 and 25-50 cm soil horizons. Particularly large changes occurred in the levels of Zn and Mn. The way set-aside arable land was kept had a weaker influence on the concentrations of easily soluble forms of copper. By seeding annual plants and leaving the grown biomass on a set-aside field, it was possible to maintain the soil abundance of available Zn on a high level and that of Cu and Mn – moderately high. Keeping soil as bare fallow favoured better accumulation of available forms of copper and manganese.

Based on the literature, this study presents the main problems associated with introducing iodine into food. The problem of iodization of table salt and its use in the production of processed food is analysed. This method of enriching the human diet with iodine is linked to the over-consumption of salt, and thus to the risk of hypertension and kidney disease. Because of the need to reduce consumption of table salt, alternative methods of supplying the body with iodine are gaining in popularity. Described are attempts to fortify foods of plant origin with iodine. One alternative method of enriching food with iodine is the cultivation of plants fertilized with iodine. The results are presented of experiments aimed at the cultivation of vegetables enriched with iodine and analysed methods of iodine fertilization: foliar application, soil application and hydroponic cultures. Also discussed are the problem of the effects of iodine, not only on yield, but also on selected physiological processes taking place in plants which are responsible for the biological quality of the crop.

Micronutrient deficiencies have increased over recent decades due to the general depreciation of the quality of poor people’s diet, both in developed and developing countries. The deficiencies of iron (Fe) and zinc (Zn) are a critical public health problem worldwide, with the negative impact on health, lifespan and productivity. Biofortification is an agricultural approach that can improve human nutrition on a global scale. Agronomic biofortification is considered a short-term and complementary strategy, but economic analyses suggest that genetic biofortification is the most effective strategy for increasing dietary Fe and Zn intakes of vulnerable populations. Enrichment of cereal grains by breeding is a high-priority area of research, and an effective strategy among other approaches, e.g, fortification, supplementation and food diversification. This review discusses the role of Fe and Zn in plant nutrition, the potential strategies for developing Fe and Zn biofortified crops and their importance in human nutrition.

Life and growth of plants and animals depends on some metals as micronutrients. However, certain forms of some metals can also be toxic, even in relatively small amounts, and therefore determine risk to the health of animals and people. Chromium is a heavy metal whose concentration in the environment is increasing. Chromium in inorganic systems occurs in several chemical forms. Only Cr(III) and Cr(VI) are significant in biological systems. Trivalent chromium is an essential nutrient component while excess chromium(VI) in biological systems has been implicated in specific forms of cancer.

Cumbers of a parthenocarpic variety Marinda F₁ were grown in the field under protective shields, i.e. a perforated PE sheet and PP needled cloth (17 g·m⁻²), during the years 2001–2003. Unshielded plots served as the control treatment. It was found that the concentrations of nitrogen, calcium and iron increased significantly in cucumber plants grown under PP needled cloth. The edible parts of cucumbers were characterized by widened K : Ca, K : (Mg+Ca) and K : Mg ratios, as well as by favorable Ca : Mg ratios.

Salt stress is known as one of the most severe abiotic factors limiting the plant production all over the world. In this study, three additives: (i) supplemental Ca (5 mmol L–1) to nutrient solution, (ii) foliar application of micronutrients (Fe, Mn and Zn at 60, 160 and 110 mg L–1, respectively), and (iii) combination of both of them were evaluated aiming to reduce the negative impact of salt stress on tomato plants cultivated in a soilless culture and improve the internal quality of fruits. The obtained results show that salinity reduced vegetative growth and physiological parameters, fruit yield and its components, and even more lowered fruit market classification of tomatoes. Salinity treatment reduced most of essential macro- and micronutrients in tomato fruit, whilst Na content was increased. Tomato productivity and fruit quality were ameliorated under saline conditions by increasing Ca into nutrient solution and applying a foliar application of micronutrients. A combination of both additives ranked the first to alleviate the adverse effects of salinity on tomatoes, followed by solo supplemental Ca into saline nutrient solution. On the other hand, the internal fruit quality of antioxidant compounds, such as vitamin C, lycopene, α-carotene, β-carotene and lutein as well as acidity, total soluble solid and dry matter percent, were increased under saline conditions.

In order to achieve a high yield and quality of apple fruit, more effective ways of fertilization are required in the modern, high density apple orchards. The objective of this research was to determine the efficiency (partial nutrient balance, PNB) of different methods (foliar and fertrigation) and forms (chelates and salts) of microelements application in relation to the levels of N fertilization in apple orchard cultivar (‘Golden Delicious’). The combined effects of these fertilizers on the number of apple fruits per tree and on the yield per tree were also studied. Foliar application of Mn, Zn and Fe had significantly higher partial nutrient balance values compared to the soil application in both years of the experiment. However, most of the PNB values were below 10% indicating relatively low efficiency of the applied fertilizers with microelements.

Compared to conventional tillage method, physical and chemical properties of soil treated with long-term zero-tillage method (direct drilling without ploughing) are different, especially soil porosity, moisture conditions, concentration of organic carbon and macronutrients. The aim of a three-year field study was to compare the content of micronutrients in soil under traditional and zero-tillage. The difference in micronutrient concentration in soil treated with different soil tillage method can affect quantity and quality of yields. The study was conducted using seven fields with 4-5 or 11 years period under diverse tillage method. Soil samples were colleted from three random points in every field on the beginning of June. Samples were obtained from two layers: 0-10 and 10-20 cm in depth using an Eijkelkamp soil sampler (diameter 2.5 cm). Micronutrients (Cu, Mn, Zn) in soil samples were determined by the AAS method after extraction with HCl at 1 mol dm-3. The results were compared using t-Student test. The tillage methods were found to have produced differences only in Cu concentrations in soil. However, it was impossible to point clearly which method resulted in a higher Cu concentration as the actual differences depended also on the year of study and the soil layer. The zero-tillage method compared to the conventional method did not produce differences in Mn and Zn concentrations. The general level of the three microelements and the differences in their levels in relation to a tillage method were similar in both soil layers.
