Opis:: Experimental material consisted of the seeds of Polan, Aldana and Dornburg soybean cultivars harvested from the field experiments in 1990-92 at Sandomierz with the following herbicides and doses: Sencor 75 WP (1.0 and 2.0 kg/ha), Tribunil 70 WP (1.0 and 2.0 kg/ha), Azogard 50 WP (1.5 and 3.0 kg/ha), Afalon 50 WP (1.0 and 2.0 kg/ha). Seeds from plots treated with a single dose of some herbicides (Tribunil 70 WP, Afalon 50 WP) did not exhibit any herbicide active residues or in case of other herbicides their level were far below permissible limits (0.1 mg/kg). The use of double doses, resulted in accumulation of the active remnants in soybean seeds but still their level did not exceed permissible limits. Differences in the level of herbicide active substances in soybean seed were found to depend on season conditions.

Opis:: All plants based on combustion of the fuel generate a large number of flue gases, which contain variety of pollutants. These include particulates, heavy metals (Hg, Cd, Tl, As, Ni, Pb), carbon compounds (CO, hydrocarbons (VOCs), (PCDD / F, PCB), acid and other gases (HCl, HF, HBr, HI, SO2 , NOx , NH3 ), whose emissions are controlled, and subjected to the European and regional limits. In municipal waste-to-energy plants large diversity of fuel results in a considerable concentration of the individual compounds which can be dangerous for the environment. Due to these facts, it is necessary to take into account a flue gas cleaning stage in every waste-to-energy plant. The article divided into two parts shows technologies and processes that can be used at this stage. It describes methods used to deal with all kinds of pollutants at flue gases treatment stage. The paper presents emission limits imposed by the European Union with examples of emissions at working municipal waste-to-energy plants, and the limits that are to be expected in the future. Some topics, as costs and residual handling, are only briefly mentioned and for more information a reader is advised to use literature which will allow him to learn more about technology, processes and problems presented in the text. The aim of the study is to present the current state of flue gas cleaning in Waste-to-Energy plants.

Opis:: Salinization and sodification of agricultural lands in arid and semi-arid regions of the world are two limiting factors in the crop production. This study was conducted to evaluate the effect of readily available agricultural residues on changing some chemical properties of saline-sodic soils. Wheat, potato, sunflower, and canola residues were separately added into three saline-sodic soils at a rate of 2% by weight and thoroughly mixed with soils. Control and treated soils were incubated for 168 days at a constant moisture and temperature. The pH, electrical conductivity (EC), soluble cations, available nitrate (NO3-) and phosphorous (P), cation exchange capacity (CEC), and exchangeable sodium percentage (ESP) were measured during the incubation. The EC increased in the response to the incorporation of plant residues, whereas the pH was reduced. The application of organic components in soils increased CEC and decreased ESP. The results showed that the maximum reduction in ESP was observed in the potato treatment because of the highest Ca2+ concentration. The average reduction in ESP of treated soil samples at the end of incubation followed this order: 16.1% (potato residue-treated soil) >12.7% (canola residue-treated soil) >11.1% (wheat residue-treated soil) >9.6% (sunflwer residue-treated soil). The potato residue was the most effective amendment in changing the chemical properties of saline-sodic soils in comparison with other organic residues. The results indicated that the application of organic residues had a positive impact on reducing the soil sodicity and improving the soil fertility depending on their chemical composition.

Opis:: With the increase of agricultural production, residues of crop are the main source of organic matter in the soil and they are alternatives to inorganic fertilizers. For this purpose, effects of organic residues (cotton stalk, maize stalk, almond bark) commonly grown in Turkey were investigated for some soil microbial activity in clay soil. In this study, incubation experiment was set up. Five doses (0%, 2%, 4%, 6% and 8%) of organic residues (maize stalks, cotton stalks or almond bark) were applied to soil. Soil microbiological properties of soil samples such as CO₂ respiration, dehydrogenase and urease activity were determined. According to the results obtained, maize stalk, cotton stalks and almond bark applications increased some soil microbiological activities, such as CO₂ respiration, dehydrogenase and urease activities according to control soil. Maize stalk in comparison to other residues affects better on the biological properties of the soil. It is determined that enhancing effects of the added organic residues (maize stalk, cotton stalk, almond bark) into the soil were changed according to the type of organic residues, dosage and application terms.

Opis:: Tillage and plant residues influence soil attributes and, consequently, soil quality. Therefore, suitable management and maintaining the stability of soil structure is important. This study was performed to evaluate the effects of tillage systems on soil quality during a 4-year crop rotation (wheat, canola, wheat and tomato) at the Agricultural Research Center of Khorasan Razavi province (Iran) from 2011 to 2015. The study was conducted as a randomized complete block design in a factorial arrangement with 3 replications. For this purpose, conventional tillage (CT), minimum tillage (MT) and no-tillage (NT) systems together with three rates of plant residues (0, 1,500, and 3,000 kg ha-1) were applied annually after harvesting. Soil quality was determined by using the integrated quality index (IQI) and Nemoro quality index (NQI) based on total data set (TDS) and minimum data set (MDS). In total, 23 physical, chemical, and biological soil characteristics were considered as TDS and 7 out of these were selected as MDS for use in the principal component analysis (PCA). Soil quality in different tillage treatments was determined and the most appropriate indices and effective characteristics for soil quality assessment were selected. Correlation coefficients between IQITDS and IQIMDS (r = 0.69) and between NQITDS and NQIMDS (r = 0.76) showed that NQI was a better indicator for assessing soil quality. The NQITDS provided a more accurate and comprehensive assessment of soil quality. However, using MDS reduced the cost and time with proper precision. Soil quality in MT and NT treatments was more desirable than the CT system, and the addition of plant residues improved the soil quality. According to the results of NQITDS, IQITDS, and IQIMDS, soil quality in the NT system with 3,000 kg ha-1 of plant residues and the MT system with 1,500 and 3,000 kg ha-1 of plant residues were more favorable than other soil tillage treatments. Soil characteristics that decreased soil quality in the conventional tillage were soil structure, macro and micronutrients, while in conservation tillage it was micronutrients, especially Zn.

Opis:: A model system was used to investigate the effect of cooking on the level of selected chlorinated carbohydrate residues in muscle fat of fattened ducks and in decoction fat.
W układzie modelowym badano wpływ gotowania na poziom pozostałości wybranych chlorowanych węglowodorów w tłuszczu mięśni tuczonych kaczek i w tłuszczu wywaru. Materiałem do badań były próbki mięśni udowych i piersiowych tuczonych kaczek. Chlorowane węglowodory (γ-HCH, DDE, DDD i DDT) oznaczano metodą chromatografii gazowej. W tłuszczu mięsa surowego stwierdzono średnio 0,04 ppm γ-HCH i 0,38 ppm DDT (udo) oraz 0,12 ppm γ-HCH i 0,78 ppm DDT (pierś). Po gotowaniu od gorącej wody w tłuszczu mięśnia udowego obserwowano średnio 0,03 ppm γ-HCH i 0,20 ppm DDT, w tłuszczu mięśnia piersiowego 0,08 ppm γ-HCH i 0,08 ppm DDT. Podczas gotowania od zimnej wody wyniki wynosiły dla uda 0,03 ppm γ-HCH i 0,15 ppm DDT, dla piersi 0,09 ppm γ-HCH i 0,29 ppm DDT. Podczas gotowania od gorącej wody w tłuszczu wywaru z uda poziom γ-HCH wynosił - średnio 0,04 ppm, DDT 0,38 ppm, dla wywaru z piersi 0,21 ppm γ-HCH i 0,93 ppm DDT. Podczas gotowania od zimnej wody w tłuszczu wywaru z uda obserowano 0,05 ppm γ-HCH i 0,40 ppm DDT, dla wywaru z piersi 0,48 ppm γ-HCH i 1,54 ppm DDT. W tłuszczu wywaru wyraźnie wzrastała zawartość DDD w porównaniu z tłuszczem mięsa surowego.

Opis:: W rolnictwie i przetwórstwie rolno-spożywczym powstają duże ilości pozostałości poprodukcyjnych, zależnie od rodzaju i wielkości produkcji ale także od stosowanych technologii. W przemyśle rolno-spożywczym najwięcej pozostałości powstaje w cukrownictwie, mleczarstwie, przetwórstwie owocowo-warzywnym, gorzelnictwie browarnictwie. Biomasa tych pozostałości stanowi olbrzymi potencjał energetyczny i nawozowy. Powinna być wykorzystywana zgodnie z zasadami biogospodarki, czyli przetworzona na bioenergię lub bioprodukty (pasze, nawozy organiczne) w zależności od jaj właściwości fizycznochemicznych. W celu zmniejszenia ilości powstających pozostałości gospodarstwa rolne i zakłady produkcyjne powinny prowadzić racjonalną gospodarkę materiałowo-surowcową i stosować najlepsze dostępne technologie produkcji. Stosunek masy pozostałości (produktów ubocznych i odpadów) do ilości produktów finalnych, powinien być uznany za jeden z głównych wskaźników nowoczesności technologii produkcji i ochrony czystości środowiska. Racjonalne wykorzystanie pozostałości poprodukcyjnych jest koniecznością dyktowaną względami gospodarczymi i ekologicznymi.
The agriculture and agri-food industry generate large quantities of production residues. The amount of residues depends on type and volume of production but also on the technologies used. In the agri-food industry the most residues are produced in the sugar industry, dairy industry, fruit and vegetable processing, distilling of alcohol and brewing. The biomass of these residues is a huge potential for energy and fertilizers. It should be used in accordance with the principles of the bio-economy and it should be processed into bioenergy and bioproducts (animal feed, organic fertilizers). The use of biomass depends on its physical and chemical properties. In order to reduce the amount of production residues the agricultural holdings and food establishments should implement rational materials and raw materials management. They should also apply the best available technologies of production. Proportion of the mass of the residues (side products and wastes) to the quantities of finished products should be regarded as one of the main evaluation indicators of modern manufacturing technology and indicators of protection of environmental quality. Rational utilization of production residues is necessary for economic and environmental reasons.

Opis:: The aim of the research was to evaluate the advancement of the naturalisation proces that concerned the reclaimed area of the former the sulphur mine in Jeziorko. It was assessed by analising the diversity of earthworms populations from the chosen five spots (field I, II, X, XX and XXI) differentiated in terms of time and direction of reclamation. Earthworms were obtained by the mixed method, according to Zajonc. The results were analyzed statistically. On the field II reclaimed for the longest period in forest direction, all 7 species of Lumbricidae were found, whereas on field X (shorter reclamation) – 5 of them. In the open spaces of fields I, XX and XXI, representatives of the examined group were not present. On field XX and XXI, earthworms were preserved only within individual old trees (Malus Mill., Populus L. poplar) growing in this area even before the period of land degradation by the sulphur mines. Within the crowns of these trees, poor clusters consisting of 1 or 2 species of earthworms were discovered (A. rosea and/or A. caliginosa).

Opis:: Among nutrients and pesticides, agricultural draining ditches also transport pollutants discharged with untreated wastewater from the municipalities adjoining the ditch. When the ditch water is used for irrigation and aquaculture, risks for the environment and food production are suggested. For the conducted field study, a shrimp farm in Sinaloa (Mexico) was used to trace organic pollutants (pesticides and pharmaceutical residues) on their way from an agricultural draining ditch to a shrimp farm fed partially by the drain water. The concentrations of pollutants in the drain water ranged from 10 ng L-1 to 453 ng L-1. The pond water of the shrimp farm contained concentrations between <10 ng L-1 and 177 ng L-1. The shrimps were contaminated by pollutants at concentrations between 40 μg kg-1 d.w. (dry weight) to 3.3 mg kg-1 d.w. (fungicide Metalaxyl). Health risks for the cultivated shrimps cannot be excluded because some pesticides are known for their toxic effects to crustaceans. The concentrations of selected antibiotics in the shrimps were low and comparable with those found in the shrimps declared as seawater shrimps from a German supermarket. The incorporation of the antibiotics was probably caused by contact to the wastewater in the shrimp ponds and/or by contaminated shrimp feed. Additionally to the anthropogenic chemicals, coliforms were determined in the water (total coliforms: 30-50 CFU 100 mL-1; fecal coliforms: 0-20 CFU 100 mL-1). These values agree with the Mexican Norm NOM-242-SSA1-2009 representing a microbiological quality of water adequate for aquaculture. The number of coliforms measured in shrimp was higher than in pond water, suggesting bioaccumulation and a potential health risk for consumers.

Opis:: The biodiversity of aqueous environments has been affected due to the disposal of wastewater highly contaminated with heavy metal ions, causing much damage to ecosystems. These pollutants are very toxic and bioaccumulate in living organisms. This work attempts to evaluate the adsorption of nickel ad cadmium ions using three biomasses from agricultural residues (corn cob – CC, orange peel – OP, and oil palm bagasse – PB) modified with alumina nanoparticles. The biomasses were characterized via compositional analysis and a point of zero charges to quantify the presence of lignin, cellulose, hemicellulose, and the feasible pH, taking advantage of the biomass charge. After modification with Al2O3 nanoparticles. The resulting adsorbents were characterized via FT-IR analysis to identify the functional groups that most contributed to the adsorption performance. Furthermore, the influence of Al2O3 nanoparticles was analysed on the adsorption capacities of the evaluated biomasses using batch systems at a temperature of 25°C and pH 6. All biomasses displayed a high content of cellulose, estimating a weight percentage of about 19.9%, 14.3%, and 13.1% for PB, OP, and CC samples, respectively. The FT-IR spectrum confirmed hydroxyl and carboxyl functional groups, which contribute to enhancing the adsorption capacities of the modified biomasses. Functional adsorption capacity was observed for all biomasses after modification with Al2O3 nanoparticles, achieving at pH 6.0 a cadmium removal from 92% (CC-Al2O3 and PB-Al2O3) up to 95.8±0.3% (OP-Al2O3). In nickel ions, it was estimated a broader adsorption capacity at pH 6.0 of about 86±0.4% after using the CC-Al2O3 sample, 88±0.1% for the PB-Al2O3 adsorbent, and 98±0.2% for the OP-Al2O3 sample, confirming the suitability of these Al2O3-modified biomasses for the removal of heavy metal ions.

Opis:: Fruit and vegetable processing by-products, undervalued until recently, are rich sources of nutrients. This study investigated properties of extruded corn puffs with addition (5–20%) of blackcurrant or chokeberry pressings. We assessed expansion rate, water absorption index (WAI) and water solubility index (WSI) of the produced extrudates, the concentration of polyphenols, and antioxidant activity measured by FRAP method and ABTS method. The puffs with addition of chokeberry pressings had higher WSI values, higher phenolic acids, flavonols, and anthocyanins content, and higher antioxidant activity than puffcorn with addition of blackcurrant pressings. The corn puffs with addition of fruit pressings contained much higher concentrations of phenolic compounds and were characterized by much higher antioxidant activity than pure puffcorn. This confirms the usefulness of addition of such fruit processing by-products in order to manufacture functional food.

Opis:: Food economy plays a major role in world development. A food chain, from an economic point of view, means a long series of interdependent management processes, which have the main goal to providing food to people. It consists of many elements like food production, harvesting, processing, storage, and trade. Fruit processing in Poland is a significant part of the Polish economy.
