Opis:: Celem podjętych badań było określenie oddziaływania związków fluoru oraz selenu (na dwóch stopniach utlenienia: IV i VI), wprowadzonych osobno oraz w mieszaninie na aktywność fosfatazową gleby lekkiej. Doświadczenie przeprowadzono w warunkach laboratoryjnych na piasku gliniastym o zawartości węgla organicznego 8,7 g/kg, do którego wprowadzono w różnych kombinacjach fluor (10 mmol/kg) oraz selen (0,05 mmol/kg). W odstępach tygodniowych przez okres 28 dni oznaczano spektrofotometrycznie aktywność fosfatazy alkalicznej i fosfatazy kwaśnej. Na podstawie otrzymanych wyników obliczono wskaźniki oporności enzymów (RS). Wykazano że wprowadzenie do gleby fluoru i selenu spowodowało istotne statystycznie obniżenie aktywności oznaczanych enzymów. Aktywność fosfatazy alkalicznej charakteryzowała się większą wrażliwością na obecność fluoru i selenu w glebie niż fosfataza kwaśna. Dla fosfatazy alkalicznej największe obniżenie RS wystąpiło po aplikacji fluoru wraz z selenem na stopniu utlenienia IV, a dla fosfatazy kwaśnej – fluoru wraz z selenem na stopniu utlenienia VI.
The aim of the study was to determine the impact of fluoride and selenium (in two oxidation states IV and VI), introduced separately and in a mixture on soil phosphatase activity soil. The experiment was carried out in laboratory conditions on loamy sand samples with organic carbon content 8.7 g/kg. Various combinations of fluoride (10 mmol kg) and selenium (0.05 mmol/kg) were added into soil samples. Over a period of 28 days, at weekly intervals. Alkaline phosphatase and acid phosphatase activities were determined by spectrophotometry. Based on the obtained results, the resistance index (RS) for enzymes was calculated. It was found that the addition of fluoride and selenium into the soil resulted in a statistically significant decrease of assayedenzyme activities. Alkaline phosphatase activity was more sensitive to the presence of fluoride and selenium in the soil than acid phosphatase. The values of RS were lowest for alkaline phosphatase in soil treated with fluoride and selenium in the oxidation state IV, and for acid phosphatase in soil treated with fluoride and selenium in the oxidation state VI.

Opis:: The aim of study was to determine the influence of NaCl and glyphosate-based herbicide Avans Premium 360 SL on acid and alkaline phosphomonoesterase activities in sandy loam. The experiment was carried out in laboratory conditions on sandy loam with Corg content 10.90 g/kg. Soil was divided into half kilogram samples and adjusted to 60% of maximum water holding capacity. In the experiment dependent variables were: I – dosages of Avans Premium 360 SL (0, a recommended field dosage – FD, a tenfold higher dosage – 10 FD and hundredfold higher dosage – 100 FD), II – amount of NaCl (0, 3% and 6%), III – day of experiment (1, 7, 14, 28 and 56). On days of experiment the activity of alkaline and acid phosphomonoesterase activity was assayed spectrophotometrically. The obtained result showed that the application of Avans Premium 360 SL decreased in acid and alkaline phosphomonoesterase activity in clay soil. Significant interaction effect between the dosage of Avans Premium 360 SL, NaCl amount and day of experiment was reported in the experiment. The inhibitory effect of Avans Premium 360 SL was the highest in soil with NaCl at the amount of 6%.

Opis:: The aim of this study was to determine the effects of glyphosate ammonium salt on the activity of some enzymes involved in the metabolism of phosphorus in the soil: acid phosphomonoeaterase (EC 3.1.3.2), alkaline phosphomonoeaterase (EC 3.1.3.1), phosphotrieaterase (EC 3.1.5.1), inorganic pyrophosphatase (EC 3.1.6.1), and a phosphorus content in a form available to plants. The experiment was carried out on loamy sand samples with organic carbon content 8.7 g kg^-1. Into soil samples the aqueous solutions of Avans Premium 360 SC (360 g glyphosate ammonium salt in 1 dm³) were added. The amount of introduced glyphosate ammonium salt was 0 (control), l, 10, 50 and 100 mg·kg^-1, on days 0 (1 hour after glyphosate application), 7, 14, 28 and 56 measured parameters were determined spectrophotometrically. The obtained results showed that the application of glyphosate ammonium salt resulted in changes of available phosphorus content and the activity of enzymes involved in the metabolism of this element in loamy sand. The effects glyphosate ammonium salt dosage and effect of day of experiment were ambiguous. Among the determined parameters the most sensitive to the presence of the glyphosate ammonium was alkaline phosphomonoesterase.
Celem podjętych badań było określenie oddziaływania soli amonowej glifosatu na aktywność wybranych enzymów biorących udział w przemianach związków fosforu w glebie: fosfomonoesterazy kwaśnej (EC 3.1.3.2), fosfomonoesterazy alkalicznej (EC 3.1.3.1), fosfotriesterazy (EC 3.1.5.1), pirofosfatazy nieorganicznej (EC 3.1.6.1) oraz zawartości fosforu, w formie przyswajalnej dla roślin. Do badań laboratoryjnych użyto glebę zaliczaną do piasku gliniastego o zawartości węgla organicznego 8,7 g·kg^-1. Do gleby wprowadzono wodne roztwory preparatu Avans Premium 360 SC (360 g glifosatu w postaci soli amonowej w 1 dm³). Ilość wprowadzonego glifosatu w postaci soli amonowej wynosiła 0 (kontrola), 1, 10, 50 i 100 mg·kg^-1 gleby. W 1., 7., 14., 28. i 56. dniu po wprowadzeniu herbicydu oznaczono spektrofotometrycznie wymienione parametry glebowe. Na podstawie przeprowadzonych badań, stwierdzono, że wprowadzenie glifosatu w formie soli amonowej spowodowało zmiany zawartości fosforu przyswajalnego oraz aktywności enzymów biorących udział w przemianach tego pierwiastka w glebie lekkiej. Nie można jednoznacznie wykazać wpływu dawki soli amonowej i dnia pomiaru na zmiany zawartości fosforu przyswajalnego oraz aktywności enzymów biorących udział w przemianach tego pierwiastka w analizowanej glebie. Spośród oznaczanych parametrów najbardziej wrażliwa na obecność soli amonowej glifosatu okazała się fosfomonoesteraza alkaliczna.

Opis:: The aim of this study was to determine the effect of three different ionic liquids (ILs): 1-butyl-1-methylpyrrolidynium hexafluorophosphate [Pyrrol][PF6], 1-butyl-1-methylpiperydynium hexafluorophosphate [Piper][PF6] and 1-butyl-4-methylopirydynium hexafluorophosphate [Piryd][PF6] on phosphatase activities in soil. The pot experiment was carried out on loamy sand (Corg content 9.0 g/kg) with spring barley as a tested plant. The ILs was used at the dosages of 0, 1, 10, 50, 100, 400, 700 and 1000 mg/kg dry matter (DM). On day 14, soil samples were collected and activities of alkaline phosphomonoesterase, acid phosphomonoesterase, phosphotriesterase and inorganic pyrophosphatase were determined. Based on the analysis of the effect measure η2 by variance analysis – ANOVA – the percentage shares of all variable factors affecting the activity of phosphatases were also defined. Obtained results showed that the application of different dosages of all ILs caused mainly non-significant changes in phosphatase activity. Changes in activity of phosphatases were often not dependent on IL dosages. The most sensitive for ILs were both phosphomonoesterases. The type of ILs had the highest percentage participation in formation of acid phosphomonoesterase activity, while dosages of ILs affected mainly alkaline phosphomonoesterase and phosphotriesterase activities.

Opis:: Fluoride is regarded as one of the strongest oxidants, which causes oxidative changes in cells of living organisms. It may both increase the content of reactive oxygen species and inhibit the activity of antioxidative enzyme. In recent years, many researchers successfully used the properties of clay minerals in the sorption of fluoride ion from water. This raises the question of the possibility of limiting the effect of fluorine on the negative changes in plants by adding bentonite to soil. A two-year pot experiment was carried out in the Greenhouse of West Pomeranian University of Technology in Szczecin, on loamy sand and sandy loam. Each sample of soil was mixed with three different concentrations of bentonite – 1, 5, 10% of dry weight (DW) of the soil and then treated with 30 mmol of F- per 1 kg of dry weight of the soil in a form of NaF solution. A control series was prepared for each soil, to which no additives were added. The medium prepared in such way was transferred to plastic pots (3 kg each) and seeded with 16 pea seeds of Pisum sativum. In three phases of pea development (4 leaves unfolded, flowering and development of fruit), fresh leaf samples were collected and the concentrations of ascorbic acid, reduced glutathione, total flavonoids and total polyphenols were measured. Sodium fluoride introduced to the soil changed the level of antioxidant parameters in the plant, which may suggest that fluoride is involved in the formation of reactive oxygen species, resulting in oxidative stress. Bentonite in a dosage of 10% reduced the toxic effects of fluoride on the oxidative balance and morphological changes in the plant, which was observed especially for loamy sand, naturally poor in clay minerals.

Opis:: This paper assesses the dissipation of napropamide and its impact on the activity of dehydrogenases, alkaline phosphatase, acid phosphatase, and urease in sandy clay loam. The experiment was carried out on soil samples with organic carbon content of 12.08 g·kg^{-1^{, total nitrogen content of 0.97 g·kg^-1, and pH 5.24 with the following variable factors: (a) dose of Devrinol 450 SC formation (containing 450 g of naprop-amide in dm³): 0 (control), 0.5, 1, 2, 4, 8, and 16-fold hold of field dose; (b) day of experiment: 1, 7, 14, 28, 56, and 112. The half-life of napropamide ranged from 33.50 to 71.42 days. The use of napropamide at the dose recommended by the manufacturer and at the dose reduced by half appeared to exhibit low toxicity in relation to enzymes determined. In contrast, the application of elevated napropamide doses decreased the values of biochemical parameters of the soil in most cases. The Pearson’s correlation coefficients showed statistically significant negative correlation between the content of napropamide residues and the enzymatic activity of the soil.}}

Opis:: The aim of the study was to determine fluoride content in sand from sandboxes in Police town (West Pomerania, Poland). This area is exposed to excessive emissions of fluoride compounds because of the proximity of chemical plants. The sand samples were collected five times in a period from March to November in 2016. Fluoride content was determined using the potentiometric method with an ion-selective fluoride electrode. The obtained results showed that fluoride content was ranged from 0.09 to 1.48 mg·kg-1 dm. The lowest fluoride content was recorded in the sand collected in place, which was the closest to the emitter, and the largest in the samples from sandbox, which was furthest from the emitter. Analyzing the changes in the content of this element over time, the largest fluoride concentration of sand occurred in July or September depending on location. Pearson correlation coefficient at p < 0.05 (r = 0.925) showed a significant positive correlation between fluoride content and the distance from fluoride emitter.

Opis:: The aim of the study was to determine the effect of spinosad on soil biochemical and microbiological properties. The experiment was carried out on sandy loam with Corg content 10.91 g·kg^-l. Spinosad, as Spintor 240 SC was added into soil in dosages: a recommended field dosage, and fivefold, tenfold, and twenty-fivefold higher dosages. The amount of spinosad introduced into soil was between 12.55 and 313.75 g·kg^-l. Moreover, soil samples without spinosad supplement were prepared as a reference. Respective Spintor 240 SC doses were converted into 1 kg soil, taking into account 10 cm depth. After application of insecticide water emulsions, soil moisture was brought to 60% maximum holding water capacity. The soil was thoroughly mixed and stored in tightly-closed polyethylene bags at 20 °C for a period 4 weeks. During the ex-periment dissipation of spinosad, soil enzymes (dehydrogenase, alkaline phosphatase, acid phosphatase, urease) and number of bacteria, fungi, actinomycetes were assayed. Obtained results showed, that dissipation of spinosad in soil was relatively fast – the DT50 of this insecticide was ranged between 1.11 and 2.21 days. Spinosad residues had different effects on soil microbiological and biochemical properties. However, over time the impact of this insecticide definitely decreased. This indicated that the use of spinosad in organic farming, particularly in the field dosage, does not pose a long-term threat to the soil environment.
