“…In order to make a comprehensive evaluation of the effect of soil contamination with copper on the stability of a soil ecosystem, one has to trace the reactions of different enzymes, both in unsown soil and in soil sown with different plants (Zaborowska et al 2015). This was confirmed by the current study because the ED 50 for dehydrogenases, urease and alkaline phosphatase was significantly lower in unsown soil than in soil sown with spring barley.…”

Study was carried out to compare the effect of the degree of contamination of soil with copper on the soil enzyme activity, depending on the type of chemical compound with which a metal reaches the soil and on the method of soil use. An effect of increasing doses of copper on growth and the development of spring barley has been studied. The study was carried out as a pot experiment on two types of soil: loamy sand and light loam. Copper was introduced to soil as copper(II) sulphate(VI) and copper(II) chloride at four doses: 150, 300, 450 and 600 mg Cu 2? kg-1 d.m. of soil. Soil without copper was used as a control sample. The experiment showed that contamination of soil with copper applied as CuCl 2 and CuSO 4 Á5H 2 O upset the homeostasis of soil. Dehydrogenases and urease were the most sensitive to contamination of soil with Cu 2? , both as copper(II) chloride and as copper(II) sulphate(VI), and acid phosphatase and alkaline phosphatase were the least sensitive. Greater changes in enzymatic activity were observed in loamy sand than in light loam. The differences in the impact of copper(II) sulphate(VI) and copper(II) chloride on the soil microbiome were relatively small, because mean ED 50 for copper(II) chloride was 341 mg Cu 2? kg-1 d.m. of soil, and for copper(II) sulphate(VI) it was 364 mg Cu 2? kg-1 d.m. of soil. This inhibitory effect of copper persisted throughout the period of the experiment. The sensitivity of spring barley to copper compounds was lower than the enzymes under study.

“…In recent years, the attention of researchers has been focused mainly on heavy metals considered most harmful to the environment. These include, among others, Cd, Hg, Cr, Pb, and Cu (Wyszkowska et al 2013 ; Zaborowska et al 2015a ). However, researchers have also increasingly focused on the contamination of soils with trace elements (Islam et al 2015 ).…”

In this age of intensive industrialization and urbanization, mankind’s highest concern should be to analyze the effect of all metals accumulating in the environment, both those considered toxic and trace elements. With this aim in mind, a unique study was conducted to determine the potentially negative impact of Sn2+, Co2+, and Mo5+ in optimal and increased doses on soil biological properties. These metals were applied in the form of aqueous solutions of Sn2+ (SnCl2.2H2O), Co2+ (CoCl2 · 6H2O), and Mo5+ (MoCl5), each in the doses of 0, 25, 50, 100, 200, 400, and 800 mg kg−1 soil DM. The activity of dehydrogenases, urease, acid phosphatase, alkaline phosphatase, arylsulfatase, and catalase and the counts of twelve microorganism groups were determined on the 25th and 50th day of experiment duration. Moreover, to present the studied problem comprehensively, changes in the biochemical activity and yield of spring barley were shown using soil and plant resistance indices—RS. The study shows that Sn2+, Co2+, and Mo5+ disturb the state of soil homeostasis. Co2+ and Mo5+ proved the greatest soil biological activity inhibitors. The residence of these metals in soil, particularly Co2+, also generated a drastic decrease in the value of spring barley resistance. Only Sn2+ did not disrupt its yielding. The studied enzymes can be arranged as follows for their sensitivity to Sn2+, Co2+, Mo5+: Deh > Ure > Aryl > Pal > Pac > Cat. Dehydrogenases and urease may be reliable soil health indicators.

“…A great increase in living standards contributes to the degradation of soil [1] by worsening its physical, chemical, and biological properties [2,3]. Contamination of soil by heavy metals is one of the most frequent, and thus one of the greatest, environmental nuisances [4,5]. The problem of contamination of the soil with heavy metals has constituted a serious threat to the environment for many years [6].…”

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.
