In the fresh samples of municipal solid waste incineration (MSWI) bottom ash, the fractional composition of Zn, Cr and Co was investigated. The BCR method was utilised to evaluate the acid soluble and exchangeable fraction (F1), reducible fraction (F2), oxidizable fraction (F3) and residual fraction (F4). Physico-chemical parameters such as pH, dry mass, and pseudo-total metal content were also determined. The percentage of zinc in fractions was in the following order: F3 (31.8%) > F1 (30.6%) > F2 (27.8%) > F4 (9.8%), for chromium F4 (88.7%) > F3 (5.4%) > F1 (3.2%) > F2 (2.7%), and in the case of cobalt F4 (59.8%) > F1 (14.3%) > F2 (13.6%) > F3 (12.3%). Mobile metal pool (F1–F3) gathered the most of zinc (90.2%) and the least of chromium (11.3%).

Fractions of Ni, Mn and Fe in the municipal solid waste incineration (MSWI) bottom ash were investigated. Three fractions of studied metals were separated according to the BCR procedure (acid soluble and exchangeable, reducible and oxidizable). Pseudo-total metal content, pH and dry mass in all samples were evaluated. The share of nickel in fractions followed the sequence: F4 (79.0%) > F3 (9.0%) > F1 (7.5%) > F2 (4.5%), for manganese: F4 (60.4%) > F1 (16.8%) > F2 (13.2%) > F3 (9.6%) and for iron: F4 (74.4%) > F2 (12.6%) > F3 (12.5%) > F1 (0.5%). Mobile pool of metals (F1-F3) contained the least of nickel (21.0%) and the most of manganese (39.7%).

The basic physicochemical properties such as: dry mass, pH, pseudo-total content of cadmium, lead and copper, were determined in the fresh bottom ash samples from a municipal waste incineration plant. In order to study fractional composition of the investigated heavy metals, the BCR method was used (F1 – acid soluble and exchangeable fraction, F2 – reducible fraction, F3 – oxidizable fraction, F4 – residual fraction). The average percentage of cadmium in particular fractions was as follows: F1 (37.5%) > F4 (27.2%) > F2 (25.3%) > F3 (10.0%), for lead: F4 (36.5%) > F2(27.2%) > F3(23.4%) > F1(12.9%), and in the case of copper F4(66.3%) > F3(22.1%) > F2(7.4%) > F1(4.2%). Among the studied metals, in mobile pool (F1-F3) the highest amount of cadmium was noted (72.8%); for lead it was 63.5%, and for copper 33.7% of the pseudo-total content.

In 2011–2013, a field experiment was carried out at the Experimental Station of Cultivar Evaluation in Szczecin-Dąbie. The experiment aimed at determining the effect of slurry without and with addition of increasing PRP Fix preparation doses on the crop yields and some of their qualitative traits. The soil where the experiment was set up was slightly acidic (pHKCL 5.95); nitrogen, phosphorus and potassium contents were 0.86, 1.55 and 2.70 g·kg-1 d.m., respectively. The total content of macro-elements for this type of soil was average. The content of bioavailable forms of phosphorus, magnesium and sulphur was average, while that of potassium was high. The content of organic carbon in soil was low, while the C:N ratio was 10.2:1 and was average for that type of soils. The obtained results show that the applied fertilisation with slurry combined with PRP Fix preparation and PK fertilisation increased the yield of winter rape seeds and spring wheat grain and the content of macro-elements being examined in them. The yields of the test plants were larger in the fertilisation objects where fertilisation with slurry with addition of 8 kg PRP Fix preparation per 1 m3 slurry was applied, when compared to those where only mineral fertilisation or slurry was used. Winter rape seeds and spring wheat grain usually contained more nitrogen, phosphorus, potassium, magnesium, calcium and sulphur in the fertilisation objects being fertilised with slurry with PRP Fix preparation in the amount of 8 or 12 kg per 1 m3 slurry with additional PK fertilisation (experimental series II) compared to experimental series I without additional PK fertilisation. Differences in the content of macro-elements in test plants after application of the fertilisation scheme being used varied. These differences were not always significant.

In the samples of fresh dehydrated sewage sludges from municipal treatment plants in Grajewo, Bielsk Podlaski, Sokółka, Dąbrowa Białostocka, Knyszyn, Mońki, Augustów, Suwałki, Sejny and Suchowola the following determinations were made: pH, pseudo-total content of Zn, Ni and Cu, organic matter and dry mass. The contents of the above-mentioned elements in fractions were evaluated using modified BCR method (four fractions: F1-acid soluble and exchangeable, F2-reducible, F3-oxidizable, F4-residual). The zinc content (mean values) in particular fractions can be arranged quantitatively in a sequence: F3 (60.8%) > F2 (20.0%) > F4 (19.9%) > F1 (3.9%), in the case of nickel: F3 ( 48.6%) > F2 (25.2%) > F4 (25.1%) > F1 (5.6%) and in the case of copper: F4 (66.3%) > F3 (35.3%) > F1 (4.2%) > F2 (3.0%). Cumulative content of zinc in mobile fractions (F1+F2+F3) ranged from 76.0 to 93.3%; for nickel from 56.3 to 89.6% and for copper from 28.8 to 53.3% of pseudo-total content.

The aim of this study was estimation of pseudo-total nickel content and its fractional composition in arable soils depending on their physicochemical properties.The research material consisted of samples taken from arable soil in 81 points of Podlasie Province. The content of pseudo-total nickel in soils and its fractional composition was determined with BCR method. The correlations between pseudo-total content of nickel, as well as its individual fractions and physicochemical properties of soils were evaluated. It was found, that pseudo-total content of nickel was typical for uncontaminated soils and ranged from 2.0 to 14.4 mg kg–1. The share of acid soluble and exchangeable fraction was above 20 %, as compared to pseudo-total content. Reducible fraction comprised 20–40 %. The most of nickel was bound to organic matter. The factors which influenced fractional composition of nickel were determined. For the light soils it was content of soil fraction < 0.02 mm, granulometric composition and pH, while for medium-heavy soils, organic carbon and magnesium content, granulometric composition and content of soil fraction < 0.02 mm. The factors related to the changes of Ni content in light soils in fraction II and IV and for medium-heavy soils in fraction I, were not determined.

Celem niniejszej pracy było określenie całkowitej zawartości niklu i jego frakcji w glebach uprawnych Podlasia oraz określenie zależności między zawartością niklu i jego frakcji a własnościami fizykochemicznymi gleb. Materiał badawczy stanowiły próbki pobrane z gleb uprawnych w 81 punktach województwa podlaskiego. Oznaczono zbliżoną do ogólnej zawartość niklu i jego frakcji metodą BCR. Obliczono zależności korelacyjne między zawartością ogólną niklu i jego poszczególnych frakcji, a właściwościami fizykochemicznymi gleb. Stwierdzono, że zawartość niklu ogółem była typowa dla gleb uprawnych niezanieczyszczonych i wahała się w szerokich granicach od 2,0 do 14,4 mg kg–1. Udział frakcji wymiennej w ogólnej zawartości niklu w badanych glebach wynosił ponad 20 %. Frakcja redukowalna stanowiła 20–40 % zawartości ogólnej. Najwięcej niklu było związane z substancją organiczną. Wyodrębniono czynniki wpływające na udział niklu w poszczególnych frakcjach. Dla gleb lekkich był to skład granulometryczny, zawartość frakcji spławialnej i pH, a w przypadku gleb średnich zawartość węgla organicznego, skład granulometryczny, zawartość frakcji spławialnej i zawartość magnezu. Nie wyznaczono czynników warunkujących zawartość niklu w II i IV frakcji gleb lekkich, a w przypadku gleb średnich zawartość tego metalu we frakcji I.
