In the production of milk on cattle-breeding farms and complexes large amount of wastewater is formed containing significant numbers of chemicals and is ecologically hazardous source of pollution of water and soil resources. Wastewater of dairy farms contain natural animal excretions, exhaust solutions of cleaning and disinfecting agents, milk residue which is washed off from internal surfaces of milking equipment, residues of feed, litter, dirt, which is washed off during washing of walls and floor of dairy cow house. Since such wastewater contain valuable organic substances they are used to fertilize plants. There are technologies of safe use of wastewater from cattle-breeding farms to fertilize pastures. Also wastewater used as fertilizer in cultivation of sugar beets, tomatoes, cucumbers, spinach, cabbage and the like. It is expedient determination of the influence of wastewater used for the fertilizer of agricultural cultures, on the soil microbiota. After all, soil fertility is inextricably linked with microorganisms that inhabit her. The aim of the work was carrying out of an assessment of influence of wastewater from dairy farms on the soil microbiota. Samples of soil for microbiological studies were selected in 20 centimetre thickness of top layer after application of wastewater of dairy farms. The total microorganism number was determined the method of sowing of soil suspension of corresponding dilutions on nutrient medium of meat-and-peptone agar (MPA). Micromycetes on Chapek medium.  The state of soil microorganisms after application in her different doses of wastewater of dairy farms was investigated. It is established, that the total number of microorganisms in soil when accounting 12 days later after application of wastewater in quantities of 500 l/ha exceeded control by 7.4%. At doses of 600 l/ha and 700 l/ha by 9.8% and 12.4% accordingly. 30 days later after application of waste-water the number of microorganisms almost did not differ from control. It was observed that after application of wastewater increase the total number of micromycetes. 12 days later after application of dose 500 l/ha,  of number of micromycetes was increased on average by 14,6%; in dose of 600 l/ha by 18.0%; in dose of 700 l/ha — by 19.6%. 30 days later after application of wastewater the total number of micromycetes exceeded control by 1.5%. It is defined, that wastewater of dairy farms in doses of 500–700 l/ha do not exert negative effect on soil microbiota.

Ketoprofen residues have been found in surface water where they present a potential risk to nontarget aquatic species. The aim of this study was to assess the impact of ketoprofen in surface waters on fish under experimental conditions. Subchronic toxic effects on 300 embryos and larvae of common carp (Cyprinus carpio) were investigated during a 30 day toxicity test with concentrations of ketoprofen: 0.003, 2.1, 6.3 and 21 mg/l. The exposure to ketoprofen showed no effect on mortality, but we observed significant delay (P < 0.05) in hatching in day 3 in fish exposed to all concentrations of ketoprofen. Significant delays (P < 0.05) in development were revealed at 2.1, 6.3 and 21 mg/l ketoprofen. On the basis of weight and growth rate evaluation and the determination of developmental stages, the lowest observed effect concentration was 0.003 mg/l. According to these results, the reported environmental concentration of ketoprofen in Czech rivers could have a negative effect on the growth and development of carp embryos and larvae. These tests have not yet been performed. Further research and search for a mechanism to reduce the incidence of ketoprofen in the waters by better wastewater treatment is required.

AbstractThe paper presents the impact of the applied technologies on milk yield of cows in dairy farms. The scope of the research covered technical equipment used in the dairy cattle breeding and milking in 50 farms on the area of Grajewo Province in Podlaskie Voivodeship. The studies were carried out in 2016 with the diagnostic survey method based on the interview questionnaire developed for this purpose. The studies proved that 68% of the respondents from Grajewo Province maintain cattle in a stanchion-tide stable system and the remaining 32% in a free stall system. The group (48%) of the surveyed farmers maintain animals on a deep litter and 34% of them use shallow litter. In case of 18% of the investigated farms, animals are maintained on a slatted floor. In case of 68% of the investigated farms their owners feed cattle in the TMR system while the remaining 32% do it traditionally. The analysed farms in milk production use mainly pipeline milking machines (38%) and bucket milking machines (36%). 22% of the investigated farms have a milking parlour and 4% own a milking robot. A statistical analysis proved a significant correlation between the maintenance system of animals, number of lairs in a cow shed, TMR feeding of cattle, manner of obtaining milk and milk yield of cows.

Introduction. The main task of treating sewage sludge is to obtain the final product, the properties of which would ensure the possibility of its utilization and minimize the damage to the environment. The sanitary and hygiene characteristics of the sediment are assessed by the presence of pathogenic microorganisms and helminths eggs. The degree of disinfection of the sediments is controlled according to SanPiN 2.1.7.573 - 96. The objective of the work. Determination of optimal doses of caustic lime for disinfection of microbial contamination of sewage sludge of household wastewater of sewerage cleaning facilities (SCF) and liquid manure of the swine complex. Material and methods. The object of the study were microbial communities of the sludge of the SCF household wastewater and liquid manure of the swine complex. Standard microbiological research methods were used in the work according to MU 2.1.5.800 - 99 and MR N FTs/4022. For representativeness, analyses were performed in triplicate. Results. Caustic lime was added in the amount of 1 to 10% of the volume (mass) of the sludge under study into the sludge of household wastewater (humidity of 97 - 98%). The contact time was 0.5 hours, 1 hour, 3 hours. At a concentration of caustic lime of 5 and 6%, the absence of microflora was noted after 1 hour, at a concentration of caustic lime 8 - 10% - after 0.5 hours. After 3 hours, for any amount of caustic lime (from 1 to 10%) in the native sludge of wastewater sewerage, all the microorganisms under study were not shown. Into the liquid manure (humidity less than 85%), caustic lime was added in the amount of 4 - 10% of the volume (mass) of the material being examined. The exposure was of 1 and 3 hours. The complete death of microbes at any exposure was observed at a concentration of caustic lime 9 and 10%. Conclusion. The investigations have shown the dynamics of death of microorganisms in studying the impact of caustic lime on both native and sterilized material to be the same. The total death of microorganisms during the treatment of sludge from household wastewater was observed at a concentration of caustic lime of 7 - 9%. The complete death of microbes in liquid manure (native and sterilized) at any exposure was observed at a concentration of caustic lime 9 and 10%.

Technological Analysis

The Lower Volga region is important for studying natural and climatic crises as a factor of cultural and economic changes since the local Neolithic and Eneolithic societies are marked by the early appearance of ceramics, cattle breeding and copper items. However, the impact of natural and climatic crises on these processes has not been considered earlier for a number of reasons. First, most of the sites had not detailed information obtained by the analytic research on past environmental and climatic situation. Second, numerous and contradictory radiocarbon dates prevented from determination of the chronological frameworks of these processes. During the period of 2007–2020 the situation has begun to change with the appearance of new archaeological information including homogenous and stratified archaeological sites. The multidisciplinary research made it possible to obtain new data on the chronological framework of the Neolithic–Eneolithic cultures of the Lower Volga region in context of paleoclimatic reconstructions. The results of archaeozoological studies and technical-technological analysis of ceramics had a significant meaning too. Determination of the species composition helped to establish differences in zoological collections of the Neolithic of the Northern Caspian and the steppe Volga region. It was demonstrated that the emergence of a food producing economy in this territory is associated not with the Khvalynsk, but with the earlier Caspian culture. The entire set of data made it possible to bring the development of the question of environmental factors in cultural and economic changes in the Neolithic–Eneolithic of the Lower Volga region to a new level.

Abstract The aim of this study was to evaluate and compare the impact of genotype and storage conditions (temperature and time) on microbiological contamination and eggshell quality. There were four genotypes of laying hens used, Czech golden spotted (CGS), Greenleg Partridge (GP), White Leghorn (WL) and commercial hybrid (CH) hens were included. After collection, the eggs were divided equally into five groups regarding the storage time (0, 14, 28 days) and temperature (5 and 20 °C). The microbiological analysis included counting of colonies forming units (CFU) of Escherichia coli (EC), Enterococcus (ENT) and total number of microorganisms (TNM) on eggshell surface, eggshell membranes and in thin albumen. The analysis of eggshell quality included the determination of eggshell proportion (SP), thickness (ST), strength (SST), index (SI) and surface (SS). Moreover, egg weight (EW) and egg weight loss (EWL) were determined. The significant effect of genotype was found in contamination of eggshell by EC, ENT and TNM, eggshell membranes by TNM and albumen by EC (all P ≤ 0.05). The significantly lowest contamination of eggshell from EC was in eggs from the WL hens (4.42 log CFU/eggshell), while from ENT was in eggs from the CGS hens (1.22 log CFU/eggshell) and from the WL hens (1.40 log CFU/eggshell). The lowest incidence of TNM was also detected in eggs from the WL hens (5.03 log CFU/eggshell). Statistically the lowest contamination of eggshell membranes by TNM was found in eggs from the WL (0.12 log CFU/eggshell membranes) and CH hens (0.15 log CFU/eggshell membranes). Regarding the effect of genotype, the GP (not detected) and WL (not detected) hens was in eggs with statistically the lowest occurrence of EC bacteria in albumen. Regarding the EW and eggshell quality, all the parameters were significantly affected by the genotype (P ≤ 0.0001). Also EWL was significantly (P ≤ 0.05) affected by genotype (after 14, 21 and 28 days of storage). There were found to be significant differences of microbial contamination of egg surface among observed hen genotypes. The penetration of selected microorganisms was also significant in contamination of eggshell membranes by TNM and in contamination of albumen by EC.

The Impact

Promoting the ratification of the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) was a key objective of the transnational women's movement of the 1980s and 1990s. Yet, few studies examine what factors contribute to ratification. The small body of literature on this topic comes from a world-society perspective, which suggests that CEDAW represented a global shift toward women's rights and that ratification increased as international NGOs proliferated. However, this framing fails to consider whether diffusion varies in a stratified world-system. I combine world-society and world-systems approaches, adding to the literature by examining the impact of women's and human rights transnational social movement organizations on CEDAW ratification at varied world-system positions. The findings illustrate the complex strengths and limitations of a global movement, with such organizations having a negative effect on ratification among core nations, a positive effect in the semiperiphery, and no effect among periphery nations. This suggests that the impact of mobilization was neither a universal application of global scripts nor simply representative of the broad domination of core nations, but a complex and diverse result of civil society actors embedded in a politically stratified world.
