The article analyses the environmental aspects of migration in the context of their environmental causes and effects, focusing, however, on the effects. It was recognized that negative changes in the environment are becoming a more and more frequent cause of migration and may lead to a very wide range of migration, which would be very difficult to control. This will, among other things, have environmental effects in countries targeted by migrants. These effects are considered, using the example of Poland and the need to provide migrants with appropriate living conditions, based on legal regulations relating to the provision of drinking water, sewage disposal and municipal waste management. Such situations should be considered by the state by preparing appropriate action strategies, determining the sources of their financing, and introducing the necessary legislative changes.

Drinking Water Production

Membrane fouling by natural organic matter (NOM), namely by humic substances (HS), is a major problem in water treatment for drinking water production using membrane processes. Membrane fouling is dependent on membrane morphology like pore size and on water characteristics namely NOM nature. This work addresses the evaluation of the efficiency of ultrafiltration (UF) and Coagulation/Flocculation/UF performance in terms of permeation fluxes and HS removal, of the water from Tagus River (Valada). The operation of coagulation with chitosan was evaluated as a pretreatment for minimization of membrane fouling. UF experiments were carried out in flat cells of 13.2×10−4 m2 of membrane surface area and at transmembrane pressures from 1 to 4 bar. Five cellulose acetate membranes were laboratory made to cover a wide range of molecular weight cut-off (MWCO): 2,300, 11,000, 28,000, 60,000 and 75,000 Da. Severe fouling is observed for the membranes with the highest cut-off. In the permeation experiments of raw water, coagulation prior to membrane filtration led to a significant improvement of the permeation performance of the membranes with the highest MWCO due to the particles and colloidal matter removal.

Safety Considerations

Two lead removal water filters were developed to lower lead levels in drinking water below 10 μg.L-1 in order to meet the new regulation given by the European Directive 98-83, applicable in December 2013. An appropriate adsorbent was selected through a stringent research program among a wide range of media, and is composed of a synthetic zeolite and an activated carbon. Two prototypes were developed: the first is a faucet-mounted filter which contains a fixed bed of the adsorbent and a hollow fiber bundle, while the second is an under-sink cartridge made of a porous extruded block of carbon and adsorbent. Both are able to treat at least 1,000 litres of any water containing on average 100 to 150 μg Pb.L-1, by lowering the lead concentration below 10 μg.L-1. Once their safety considerations were addressed by an independent laboratory according to the French Ministry of Health recommendations, 20 prototypes were installed at consumers' taps in northeastern France. Their performance in terms of lead removal, HPC control and bad taste and odor reduction was followed for 6 months. This field testing program resulted in the validation of both prototypes which meet the new French Ministry of Health recommendations and assures that the filtered water is fully ED 98-83 compliant. Their commercialization will be launched first in France in middle 2002.

A 300-km portion of the Saint Lawrence hydrological basin in the province of Québec (Canada) and 45 water treatment plants were studied. River water used by drinking water treatment plants was analyzed (6-L sample volumes) to determine the level of occurrence of bacterial indicators (total coliforms, fecal coliforms, and Clostridium perfringens) and pathogens (Giardia lamblia, Cryptosporidium, human enteric viruses). Pathogens and bacterial indicators were found at all sites at a wide range of values. Logistic regression analysis revealed significant correlations between the bacterial indicators and the pathogens. Physicochemical and treatment practices data were collected from most water treatment plants and used to estimate the level of removal of pathogens achieved under cold (0°C-4°C) and warm (20°C-25°C) water temperature conditions. The calculated removal values were then used to estimate the annual risk of Giardia infection using mathematical models and to compare the sites. The estimated range of probability of infection ranged from 0.75 to less than 0.0001 for the populations exposed. Given the numerous assumptions made, the model probably overestimated the annual risk, but it provided comparative data of the efficacy of the water treatment plants and thereby contributes to the protection of public health.Key words: public health, drinking water, health risk, pathogen occurrence.

Purpose. The purpose of the scientific article is to establish the ratio of the meanings of the concepts "trademark", "brand" and "well-known" trademark and then to characterize their common and distinctive features. Indicate the gaps in current legislation and the need to refine certain rules in this aspect to determine the aspects of protection and protection of the brand. Methodology. The methodology includes a comprehensive analysis and generalization of the available scientific and theoretical material and the formulation of appropriate conclusions and recommendations. During the research, the following methods of scientific knowledge were used: terminological, dialectical, logical-semantic, logical-normative, system-structural. Results: in the course of the conducted study, the main and optional components of the brand are determined, which make it possible to determine the features of its legal protection. It has been proved that despite a fairly wide range of domestic and international regulations, there are certain shortcomings of the brand protection mechanism. Originality. The study found that a trademark differs from a brand in that a trademark is a designation that is only the basis of the brand, as for the trademark are not essential such properties of the designation as a certain level of information among consumers and quality as a basis. gaining a reputation; the concept of "brand" is an evaluative, conditional concept, and therefore its consolidation at the regulatory level is impractical. It is sufficient to establish the factors on the basis of which the trademark can be considered "well known". A "well-known" trademark is a designation that is familiar to a wide range of consumers through its use to designate certain goods. Practical importance. The results of the study can be used in law-making activities for the purpose of legal regulation of public relations in the sphere of legal protection of the brand.

Diarrheal Morbidity

This study used a unique longitudinal survey of more than 3000 mother-infant pairs observed from pregnancy through infancy. The sample is representative of infants from the Cebu region of the Philippines. The sequencing of breast-feeding and diarrheal morbidity events was carefully examined in a longitudinal analysis which allowed for the examination of age-specific effects of feeding patterns. Because the work controlled for a wide range of environmental causes of diarrhea, the results can be generalized to other populations with some confidence. The addition to the breast-milk diet of even water, teas, and other nonnutritive liquids doubled or tripled the likelihood of diarrhea. Supplementation of breast-feeding with additional nutritive foods on liquids further increased significantly the risk of diarrhea; most benefits of breast-feeding alone on in combination with nutritive foods/liquids became small during the second half of infancy. Benefits of breast-feeding were slightly greater in urban environments.

Abstract The abuse of antibiotics is becoming more serious as antibiotic use has increased. The sulfa antibiotics, sulfamerazine (SM1) and sulfamethoxazole (SMZ), are frequently detected in a wide range of environments. The interaction between SM1/SMZ and bacterial diversity in drinking water was investigated in this study. The results showed that after treatment with SM1 or SMZ at four different concentrations, the microbial community structure of the drinking water changed statistically significantly compared to the blank sample. At the genus level, the proportions of the different bacteria in drinking water may affect the degradation of the SM1/SMZ. The growth of bacteria in drinking water can be inhibited after the addition of SM1/SMZ, and bacterial community diversity in drinking water declined in this study. Furthermore, the resistance gene sul2 was induced by SM1 in the drinking water.

Analyzing changes in vibration properties (e.g. natural frequencies) of structures as a result of damage has been heavily used by researchers for damage detection of civil structures. These changes, however, are not only caused by damage of the structural components, but they are also affected by the varying environmental conditions the structures are faced with, such as the temperature change, which limits the use of most damage detection methods presented in the literature that did not account for these effects. In this article, a damage detection method capable of distinguishing between the effects of damage and of the changing environmental conditions affecting damage sensitivity features is proposed. This method eliminates the need to form the baseline of the undamaged structure using damage sensitivity features obtained from a wide range of environmental conditions, as conventionally has been done, and utilizes features from two extreme and opposite environmental conditions as baselines. To allow near real-time monitoring, subsequent measurements are added one at a time to the baseline to create new data sets. Principal component analysis is then introduced for processing each data set so that patterns can be extracted and damage can be distinguished from environmental effects. The proposed method is tested using a two-dimensional truss structure and validated using measurements from the Z24 Bridge which was monitored for nearly a year, with damage scenarios applied to it near the end of the monitoring period. The results demonstrate the robustness of the proposed method for damage detection under changing environmental conditions. The method also works despite the nonlinear effects produced by environmental conditions on damage sensitivity features. Moreover, since each measurement is allowed to be analyzed one at a time, near real-time monitoring is possible. Damage progression can also be given from the method which makes it advantageous for damage evolution monitoring.

The key issue of this article is inclusive education in connection with the formal and legal aspects of students’ safety when they are staying in educational institutions. In the first part, author describes the basic assumptions of the social model of education and it’s international conditions, also referring to solutions that have been recently implemented in the Polish education system. The second part indicates the problems that may be met by educational institutions and teachers trying to achieve a state of full inclusion. They relate to the school’s caring function in terms of security guarantees. The diversity of student population, especially wide range of educational needs may make it impossible for teachers to develop specific approach to individual pupil. It’s caused by formal items, largely determined by the financial situation of particular local government units.

Abstract The article presents 9 water alerts illustrating the state and problems of water management in Poland three years after the entry of the new Water Act into force on January 1, 2018. The alerts were developed by a group of experts critically assessing some of the introduced legislative changes. The alerts analyzed the main problems related to drought and flood protection as well as the specificity of water management in cities and rural areas. Postulates to improve the legal regulations in the field of water management and financing, its integration with spatial planning and educational needs in this regard were also presented. The content of 8 alerts is briefly discussed, and the problem of water–agriculture interaction is presented in more detail. The article indicates that legal regulations of water management are particularly difficult as they apply to the entire society, almost all economic sectors and the natural environment, and its preparation must be carried out with extreme care after many analyzes and debates.

The current situation in Russia concerning generation and disposal of municipal solid waste (MSW) is characterized by significant environmental pollution, irrational use of natural resources and, as a result, significant economic damage. Measures taken at the federal and regional levels is focused on achieving optimal efficiency in waste management. However, an increasing financial burden on legal entities due to higher standards of MSW formation may lead to negative trends in economic development caused by lower competitiveness of enterprises, worsened investment climate and business activity. The study is aimed to assess regulating processes of municipal waste management in connection with the development of an effective system of recycling and reuse of MSW.
