“…At the same time, the effect is more pronounced in sandy formations than in loamy formations [36]. One may suppose that as a consequence of the significant dependence between the activity of arylsulfatase and its resistance, the addition of organic substances (i.e., cellulose, compost, manure, or bark) to soil contaminated with heavy metals may contribute to an improvement of both parameters [42].…”

Contamination of soils by heavy metals is a severe problem because of disturbances caused in the functioning of the soil and the whole ecosystem. Therefore, the aim of our research was to determine the influence of contamination of soil by zinc, copper, nickel, cadmium, and lead on the activity of arylsulfatase. A novel element of the study is a comparison of the response of arylsulfatase to five heavy metals in three soils with two pH ranges: 7.0 and 5.5. The studies were carried out under laboratory conditions. The soils (loamy sand, sandy loam, sandy clay loam), with pH 7.0 and 5.5 and contaminated with zinc, copper, nickel, cadmium, and lead were incubated for 30, 60, and 120 days. After each period, the activity of arylsulfatase was determined. Base on the activity of arylsulfatase, a resistance index of arylsulfatase (RS) to contamination with heavy metals was calculated. The highest activity of arylsulfatase was found in sandy clay loam, while the lowest was found in loamy sand. A significant correlation between the resistance of the enzyme and the level of contamination of the soil with heavy metals was proved. Arylsulfatase was most sensitive to the effects of zinc, copper, and nickel, while cadmium exerted a somewhat weaker influence and lead the least. The enzyme exhibited a higher resistance to the influence of heavy metals in neutral soils than in acidic soils. The toxic effect of heavy metals can be ordered as follows: zinc > copper > nickel > lead > cadmium.

“…Wyszkowska et al (2013a) are of the opinion that straw generates much higher resistance of individual enzymes. It cannot be disputed that the stimulating effects of classic fertilizing agents were demonstrated by analyzing the tested soil samples with the EF coefficient.…”

Zaborowska M., Kucharski J., Wyszkowska J. (2015): Using basalt flour and brown algae to improve biological properties of soil contaminated with cadmium. Soil & Water Res., 10: 181-188.In order to achieve homeostasis of soil, the potential of alleviating substances (two innovative: basalt flour and brown algae extract against two classic compounds: barley straw and compost) were analyzed in soil contaminated with cadmium. The studies thus determined the activity of urease, number of ammonification bacteria, nitrogen-immobilizing bacteria, Arthrobacter sp., Azotobacter sp., and spring barley yield. The analyzed parameters were presented as the following indices: RS -resistance of soil; EF -fertilization effect of an alleviating substance; and R:S -rhizosphere effect. Cadmium was applied as CdCl 2 •2.5H 2 O at the following doses: 0, 4, 40, 80, 120, 160, and 200 mg Cd 2+ /kg of soil. Straw increased the values of most examined parameters, mainly at lower doses of cadmium. Among the cultivated plants, resistance was most stimulated by compost. Basalt flour and brown algae extract did not play a major role in the recovery of contaminated soil. Ammonification bacteria were the least sensitive to stress associated with the deposition of cadmium in soil, whereas Azotobacter sp. was the most sensitive. Urease was found to be a reliable indicator of soil condition.

“…The factor which may explain it is the soil's organic matter (bAdorA 2011). In soils with a higher organic matter content, a weaker toxic effect of zinc on the biochemical properties of soil is observed (bååtH 1989, Moreno et al 2009, bAdorA 2011, boros et al 2011, WyszkoWskA et al 2013a). However, studies on the activity of acid and alkaline phosphatases, enzymes involved in the cycling of phosphorus, have demonstrated that they can be inhibited by soil pollution with zinc (cAstAldi et al 2004, HinojosA et al 2004, Moreno et al 2009, kAbAtA-PendiAs 2010.…”

The paper gives a comprehensive insight into the role of zinc in the biosphere. It reviews numerous functions of this metal at various levels of the organisation of ecosystems. An attempt has ben made to assess its importance as a microelement, while not neglecting its toxicity due to excessive accumulation of zinc in the environment. Zinc is a natural component of the Earth's crust, but in many places it has accumulated in amounts near or above the safe levels. Currently, the use of this metal is very broad, and therefore attention should be drawn to possible consequences arising from elevated levels of zinc in the environment. Dispelling controversies surrounding heavy metals is a necessary step for gaining systematic and wider knowledge on these elements. This in turn will create an opportunity for the development of strategies and subsequent actions undertaken by everyone, from individuals to major international industrial corporations, aimed at achieving homeostasis in an environment polluted with heavy metals. Increased levels of zinc can adversely affect microbiological and biochemical processes occurring in the soil and the development of plants, which has a negative impact on the quantity and quality of crops. Therefore, low bioavailability of heavy metals, including zinc, in agricultural land is a key to the stability of ecosystems and food security.Keywords: sustainable development, zinc toxicity, plant nutrition, microbiological and biochemical activity.prof. dr hab.
