“…The background value of Cu in plants (10 mg/kg) stated by Markert (1995) and Kula (1998) is only slightly higher than that stated by Markert (1995). The growth depression of sensitive plants was observed at 15-20 mg/kg Cu in tissues (Kloke et al 1984), and 10% yield decrease is most likely at Cu concentration within the range of 10-30 mg/kg (MacNicol and Beckett 1985). Cu concentrations in plants were mostly lower compared to the surface soil layers.…”

The objective of this research was to evaluate trends and relationships of energy and toxic elements accumulation in A-horizon (the depth of 0–5 cm) of soils and in selected plants of the hemioligotrophic (Dystric Cambisols) and oligotrophic (Skeletic-Rustic Podzols) spruce ecosystems situated along transect (750–1110 m a.s.l.) in the NP Slovenský raj (Eastern Slovakia). The results showed that EU limit values of risk elements in agricultural soils were exceeded for Cu and Cd at the altitude of 750–760 m a.s.l., and in case of Cd also above 1000 m a.s.l. Relationship between energy and toxic elements in soils revealed that with an increasing amount of energy, contents of Zn and Cu significantly declined with altitude (r > –0.5 or r > –0.9). The background value of Cu was exceeded in all plants, that of Zn for Dryopteris filix-mas and Rubus idaeus. Furthermore, excessive accumulation of Cd was revealed by all plants. Cu contents in soils were dominant in determining Cu uptake for Vaccinium myrtillus (r > 0.5); Zn and Cd for V. myrtillus (r > 0.6), D. filix-mas (r > 0.5 or r > 0.8) and Fagus sylvatica (r > –0.8 or r > –0.5); Zn also for R. idaeus species (r > 0.4). The soil-plant transfer coefficients higher than 1 hinted R. idaeus on the plots at the altitude of 960 m a.s.l. (Cd 1.1, Cu 1.2, Zn 3.1), which appears as an excellent native indicator of forest ecosystem contamination.

“…The highest accumulation coefficient was for cadmium, then for nickel and the lowest for lead. According to Kloke et al (1984) and Kabata-Pendias and Pendias (1999) in the plant-soil system each metal has different absorption properties and, at the same time, different accumulation coefficient. According to those publications cadmium has the highest accumulation coefficient (1-10) while for nickel it is much lower (0.1-1), and for lead it was the lowest (0.01-0.1).…”

Abstract. The aim of this paper is to determine cadmium, lead and nickel concentration in different herb plants and in the soil collected in the areas close to winter wheat and grain maize fields. The following herbs were analyzed: Achillea millefolium, Cichorium intybus L., Equisetum arvense, Polygonum persicaria, Plantago lanceolata L., and Plantago major L.. They were sampled one and ten meters away from the edge of the fields. The plants, 70 of each species, were collected during the flowering stage from 1 to 20 July 2014. At the same places soil samples were taken. Cadmium, lead and nickel concentration was determined with inductively coupled plasma-atomic emission spectrometry. All the herbs growing near the wheat field, except for Cichorium intybus L., had lead concentration above the limit. For other metals the concentration was below the limits set for dried herbs. Herbs plants growing close to the wheat field had a higher concentration of heavy metals than the same plants growing near the grain maize field. The average concentration of cadmium, lead and nickel in the soil around the fields was much lower than the concentration of the same metals in average, non-contaminated soil. In the soil-plant system the highest accumulation coefficient of heavy metals was for cadmium, then for nickel while the lowest was for lead.

“…Among the crops, spinach had generally very high transfer factors, indicating that cultivation of this species, along with other leaf vegetables like Table 1. Relative accumulation of heavy metals in edible plant parts of different crops (Kloke et al 1984) Variation in heavy metal accumulation was also observed within the plant. Except for roots, the highest concentrations are found in leaves, whereas the lowest are typically observed in seeds (Machelett et al 1993).…”

Heavy metal contamination affects large areas of Europe and worldwide. Hot spots of pollution are located close to industrial sites, around large cities and in the vicinity of mining and smelting plants. Agriculture in these areas faces major problems due to heavy metal transfer into crops and subsequently into the food chain. This paper gives an overview on simple but effective countermeasures to reduce the transfer of heavy metals to edible parts of crops. Since crop species and varieties largely differ in their heavy metal uptake, choosing plants with low transfer factors (e.g., legumes, cereals) may reduce metal concentration in edible parts significantly. Cultivating crops with higher heavy metal uptake capacity, e.g., spinach or lettuce should be avoided. The application of soil amendments is another very effective measure to reduce the concentration of heavy metals in crops. Both organic (e.g., farmyard manure) and inorganic amendments (e.g., lime, zeolites, and iron oxides) were found to decrease the metal accumulation. Further effective methods to reduce metal transfer into food chain include crop rotation and cultivation of industrial or bio-energy crops. It is concluded that the methods presented here comprise several tools, which are easy to apply, and are effective to allow safe agriculture on moderately contaminated soils.
