Opis:: The black sands found on certain Ecuadorian beaches present a high ilmenite contents up to 50%. In this work, TiO₂ was obtained from the black sands of Muisne beaches – Ecuador by combining the thermal, chemical and ion exchange treatments. For the thermal treatment, the raw material was smelted at temperature of 1100 °C using a basic flux. Subsequently, the chemical treatment was initiated in the presence of Fe⁰ metal using chemical digestion with HCl, and the sample was purified by separating the precipitates from a series of reactions developed at different pHs with NH₄OH, Na₂S and HCl. The final effluent resulting from the last HCl digestion was purified by ion exchange using Amberlite IRA 400 resin of strongly anionic character. The effluent is then treated in basic medium and the resulting precipitate is calcined. The recovery yield of the TiO₂ pigment was 46% with 92% purity.

Opis:: The aim of this study was to determine the effect of water extracts prepared from fresh and dry matter of winter savory (Satureja montana L.) on mortality of wingless females and larvae of black bean aphid (Aphis fabae Scop.). The experiment was conducted in the laboratory, in six replicates. Dry extracts were prepared at concentration of 2%, 5% and 10%, while the fresh plant at concentration of 10%, 20% and 30%. Stomach poisoning of extracts was determined by soaking broad bean leaves in the respective solutions, and then determining mortality of wingless female and larvae feeding on leaves thus prepared at 12 hour intervals. The results of the experiment showed that the extract prepared from dry matter at the highest concentration (10%), as well as the extracts from fresh matter at concentration of 20% and 30% contributed to an increase in mortality of wingless female of black bean aphid. Meanwhile, extracts prepared from both dry and fresh matter at two highest concentrations caused an increase in mortality of larvae of this pest. Furthermore, with increasing concentrations of analysed extracts prepared from both fresh and dry matter of winter savory, their negative effect on wingless females and larvae usually increase.

Opis:: A high level of anthropopressure has been registered in Sevastopol region, connected with its strategic role as the main city in the region, but also due to Russian Black Sea Fleet stationing there for many years. A significant source of the Black Sea contamination in Sevastopol area is the industry located in this city, municipal waste and agriculture. Implementing measures aimed at protection of the Black Sea and the evolution of their results requires monitoring conducted in the regions with various levels of anthropopressure. The work was aimed at the assessment of copper and cadmium content in water and algae in selected bays of the Black Sea in the vicinity of Sevastopol. Samples of water and algae were collected in August 2012 from eight Sevastopol bays (Galubaja, Kozacha, Kamyshova, Kruhla, Strieletska, Pishchana, Pivdenna and Sevastopolska) and from the open sea in the vicinity of Fiolent. Algae (Cystoseira barbata and Ulva rigida) were collected from the same places. Collected water was preserved on the sampling place and brought to the laboratory where its copper and cadmium concentrations were assessed. Collected algae were rinsed in distilled water, dried, then homogenised and mineralised. Copper and cadmium content were determined in the mineralizates using ASA method with electrothermal atomisation. Cadmium concentration in water ranged from 0.13 to 1.74 μg Cd dm ^-3, and copper from 7.07 to 22.56 μg Cd dm,^-3. Considerable differences in the content of the analysed elements were registered in individual bays. The highest content was assessed in Galubaja and Sevastopolska bays, whereas the lowest one in the water collected in the open sea and in Pivdenna bay. Copper concentrations in the analysed algae fluctuated from 3.375 to 14.96 mg Cu kg ^-1 d.m. No differences were noted in this element content between the algae species. Cadmium content in the algae ranged from 0.133 to 1.133 mg Cd kg^-3 d.m. Higher accumulation of cadmium was observed in Cystoseira barbata than in Ulva rigida. The value of copper bioaccumulation coefficient (BC) ranged from 181 to 1201, whereas cadmium from 181 to 5256. The contents of the analysed metals, both in biotic and abiotic elements of the studied ecosystems point to anthropogenic enrichment and the results obtained for Sevastopolska, Galubaja and Kozacha bays indicate a hazardous, excessive bioaccumulation of copper and cadmium and to potential threat to the life of aquatic organisms and seafood consumers.

Opis:: The discharge of industrial effluents containing dyes such as methylene blue (MB) and safranine T (ST) into water resources has caused serious problems for humans and organisms which live in water. On the other hand, the seeds of nigella sativa have been known to be effective and economical materials that present an excellent performance of dye removal from various types of wastewater. In this study, a different method from the existing literature was used, where the black cumin seeds (HBCS) were heated for a twenty-four hour period at 85 °C and ground to 300 µm particle size to obtain new adsorbents for (MB) and (ST) dye adsorption from aqueous solutions. Four operating variables, which show a strong impact on adsorption, were tested by conducting a batch mode adsorption experiment and these were: the dye solution’s initial pH (pH), the contact time (t), the initial concentration of the dye (Co), and the mass of the adsorbent (ma). The sorption capacity of the adsorbent (q) and the dye removal efficiency (% Rem) were utilized as indicators of the impacts of selected operating variables on adsorption processes. It was found that the adsorption of MB and ST dyes increased when the initial concentration of the solution is higher. The adsorption of MB and ST dyes onto HBCS with initial concentration of 50 mg/L was 3.39 mg/g and 4.36 mg/g, respectively. The equilibrium values for the MB and ST dyes corresponded with the Freundlich isotherm model onto HBCS highlighting the multi-layer adsorption process occurring which describes the interactions between the modified HBCS and the two dyes. The findings demonstrate that the optimum adsorption processes of the MB and ST dyes accrued in the 120 minutes and obtained at pH 10.7 and 11 for MB and ST, respectively. These conditions provide a negative charge for the surface of HBCS, causing its attraction to the positive charge of the MB and ST dyes. Kinetic studies elucidated that the MB and ST dyes adsorption onto HBCS most corresponded with pseudo-second order. The findings of this study could be implemented functionally in the industrial wastewater treatment sector.

Opis:: The aim of the study was to determine the effect of aqueous extracts of dried chamomille (Matricaria chamomilla L.), in concentrations of 2%, 5% and 10%, and fresh parts of this plant, in concentrations of 10%, 20% and 30% on survival of black bean aphid (Aphis fabae Scop.) on the leaves of broad bean (Vicia faba L.) variety “Bartek” and on feeding of Colorado potato beetle (Leptinotarsa decemlineata Say.) on the leaves of potato (Solanum tuberosum L.) variety “Bellarosa”. In these researches on impact of water extracts from chamomille on mortality of wingless females and larvae of black bean aphid, 15 laboratory’s observations in the 8-hour intervals was made. In the studies of the effects of aqueous extracts of chamomille on the dynamics of Leptinotarsa decemlineata feeding on the potato leaves, 4 laboratory’s observations in 12-hour intervals was made. Observations were carried out in 6 replicates divided into L2 and L4 larvae stages. Aquatic extracts of chamomile limited the survival of black bean aphid larvae and wingless females – the higher the concentration, the stronger the effects of the extract, where young insects were found to be more susceptible. Extracts of the dried plant whose concentration was below 5% and extracts of the fresh plant whose concentration was below 20% were found to be ineffective against black bean aphids. In all the analysed concentrations the aquatic extracts of chamomile were found to be ineffective against L2 and L4 larvae of Colorado potato beetle.

Opis:: This article discusses the ways of solving the problems of fruiting and increasing the yields, as well as obtaining high-quality standard seeds from promising seed plants of black saksaul (Haloxylon aphyllum (Minkw.) Iljin). It presents the results of studying the effect of irrigation and the use of fertilizers on the annual growth of the apical shoots of saksaul, and the effect of irrigation on the further stability of seed plants fruiting for sustainable seed supply for reproduction of saksaul deserts and forest amelioration of deserts. The morphological description of the soil by profiles has been given, and the effect of irrigation on the soils of the type II forest conditions has been described. This study was aimed at resolving the problem of fruiting frequency, increasing the yield and quality of promising black saksaul seed plants by determining the moisture dynamics in the one-meter thick soil layer under saksaul specimens for determining the methods, norms, and time of irrigating seed plants. Long-term observations show that well-developed specimens of black saksaul have appeared in the last 15-20 years on the roadside in some settlements, e.g., Bakbakty, Bakanas, Akkol, Koktal, Karoy, the motor road in village Kanshengel, Topar, Araltobe, Akzhar in the Almaty area, which passes through natural saksaul plantings and the soil with the formation of layered clay, sandy loam, and crushed stone. On the one hand, this was promoted by the presence of layered and well-aerated roadsides of the bulk roadbed, and on the other hand, by additional wetting from the runoff of precipitation from the asphalt pavement.Naturally, these saksaul plantings growing along the roads alone or in rows give a good yield when fruiting; seed plants may also be identified in these groups.

Opis:: Most of the algae are eukaryotic organisms commonly found in the aquatic environment. They are characterized by a great variety of species and the possibility of growing under various conditions. They photosynthesize, mainly needing light, water and carbon dioxide to grow. Algae can be used in various branches of the economy for the production of food, animal feed, bio-fertilizers, pigments, they can be used for sewage treatment or carbon dioxide sequestration. The aim of the work was to investigate the effect of the material from which the walls of containers are made on the bioreactors for algae cultivation. Two wall materials were used in the research: shiny aluminium foil and matte black light-absorbing paper. The content of photosynthetic pigments in algae cells, optical density, temperature and pH were examined. The tests were performed in triplicate and the standard error was calculated with the 95% confidence interval. It was observed that the glossy aluminium foil wall significantly improved the growth of the Chlorella vulgaris algae at the lowest light intensities by more than 4 times chlorophyll a compared to the sample placed in a container with walls of matte black paper. This means that the use of walls in shiny aluminium foil containers can reduce the lighting costs and contribute to an increase in the produced biomass.

Opis:: The purpose of the research conducted was to define the impact of the various aqueous extract concentrations, prepared from the dried (in concentrations 2%, 5% and 10%) and fresh (in concentrations 10%, 20% and 30%) tansy (Tanacetum vulgare L.) mass, on the feeding of pea leaf weevil (Sitona lineatus L.), and the mortality rate of black bean aphid (Aphis fabae Scop.). The studies showed that in order to limit the feeding of pea leaf weevils considerably, it is necessary to use at least 5% extract of the dried tansy mass or 20% extract of the fresh tansy mass. The impeding effect on the feeding of pea leaf weevils was correlated positively with the extract concentration. The insecticide effect of the aqueous extract of tansy on black bean aphid was revealed not earlier than after 12 hours with the use of at least 20% extract of the fresh tansy mass and 5% extract of the dried mass (only in relation to aphid larvae). Nevertheless, the extracts of lower concentration also demonstrated the insecticide effectiveness although delayed (36–60 hours after the application). As compared to other studies conducted according to the same methodology, it was demonstrated that the tansy aqueous extracts are characteristic for a high deterrent activity in relation to the pea leaf weevil beetles (higher than the extracts of absinthe and similar to the extracts of pepper mint and sage) and a quite high aphicidal activity (higher effectiveness than in the case of the aqueous extracts of lemon balm but lower than the extracts of tarragon and absinthe).

Opis:: The assessment of surface water quality and technogenic loading on the separate regions of the North-Western Black Sea, namely the Mykolaiv region, was performed in this work. The water quality assessment was conducted using the graphical method that allows determining the suitability of water for the certain types of water using, as well as the method of calculating a water pollution combinatorial index. The estimation of the technogenic loading is based on calculating a technogenic loading module. It was found that the surface waters of the Mykolaiv region do not meet the requirements of fisheries in relation to most quality indicators. According to various standards, this surface water quality in this region is characterized by the “polluted” – “very dirty” categories. A reduction of the technogenic loading by the volume of wastewater discharges since 2006 can be determined. According to the pollutant discharge indicators, a steady decrease of the level of loading has been noted since 2005, which is caused by a reduction of wastewater discharges.

Opis:: The objective of this study was to determine the effects of various concentrations of water extracts prepared from the fresh or dry matter of lemon balm on Sitona lineatus L. and Aphis fabae Scop. behaviour. The assessment pertaining to the feeding intensity of beetles was carried out by measuring the surface of feeds caused by S. lineatus. While examining the effect of extracts on A. fabae, the mortality of wingless female and aphid larvae was determined. In the studies on the olfactory reaction glass olfactometer "Y tube" and 4 armed arena olfactometer were used. The results of the experiment showed that the water extract prepared from dry matter of lemon balm with 2% concentration limited the feeding of both female and male of S. lineatus. The increase in the mortality of the black bean aphid females and larvae was obtained only after applying the extracts from fresh and dry matter at highest concentrations. The evident deterrent reaction of the odour substances obtained from the lemon balm plants towards the beetles of S. lineatus, could find application in ecological farms via introducing the plant as an accompanying crop to the main crops. The winged individuals of A. fabae did not react to the abovementioned factor.

The research of the impact of the soil cultivation methods upon the humus content is an urgent scientific and practical task of modern agriculture. This paper analyzed long-term (45 years) field experiments on the impact of ploughing, deep and shallow non-moldboard tillage upon the humus content in the chernozem soil of central Ukraine. The research materials reflect a broad picture of influence of the processing methods upon the accumulation of total humus. For example, with respect to ploughing with deep non-mouldboard cultivation, accumulation of the total humus in the 40th year of research, was +0.0028%; with shallow non-mouldboard cultivation it was +0.0005%.

Opis:: This study aimed to prepare thermoplastic elastomeric nanocomposites with Low-Cost Hybrid Filler Oil Palm Boiler Ash/Carbon Black as New Material. Hybrid filler composites promise to overcome the limitations of composites. The effects offered by the matrix and filler are responsible for improving the properties of the composite. The preparation of thermoplastic elastomer was carried out in two stages. The first stage involves mixing a rubber compound with filler. The second stage is blending the compound, HDPE, and PE-g-MA using an Internal Mixer. The results show that the peak intensity increased along with the amount of OPBA in TPE. The increase in peak intensity was caused by the rise in the number of crystalline phases in the nanocomposite. In general, the absorption bands are almost the same. The samples analyzed showed absorption band vibrations (Si-O-Si), in-plane strain vibrations (Si-OH), and symmetric strain vibrations (Si-O-Si), C―H deformation, –CH symmetrical stretching of the CH2 group appeared on each sample that FTIR has analyzed. Thermoplastics show good interaction between filler and matrix, so it can be assumed that these interactions can improve the mechanical properties of TPE. Differential Scanning Calorimetry (DSC) shows an increase in the number of peaks in the sample with 60/40 phr filler.

Opis:: To prevent the serious threat of textile wastewater, researchers have developed adsorption-based wastewater treatment using cheap, yet effective, adsorbent materials. Of which is natural bentonite, that has the advantages for adsorption due to its porous structure and functional groups but still suffers from its low affinity against anionic and hydrophilic azo dyes. Herein, we aimed of improving the affinity by amino acid tryptophan embedment into the locally isolated natural bentonite collected from Aceh Province, Indonesia. The prepared bentonite samples were characterized using Fourier transform infrared, X-ray diffraction, and scanning electron microscopy. Adsorptive removal was performed on naphthol blue black (NBB) in a batch system with variations of contact time, pH, and adsorbent dosage. The isotherm studies were carried out at optimum conditions (contact time=15 minutes; pH 1; adsorbent dosage=0.2 g) with several models including Langmuir, Freundlich, Sips, and Redlich-Peterson isotherm models. The characterization results revealed that the modification altered its functional group, crystallinity, and micro-surface morphology that add more benefits for adsorption. At optimum conditions, 99.2% NBB has been successfully removed from the aqueous solution. The isotherm studies suggested that the NBB adsorption onto the tryptophane-modified natural bentonite was dependent on Sips isotherm model (R2=0.999; root-mean-square-errors=1.11×10-4 mg/g).
