This paper aims at presenting the possibilities of applying gas chromatography for the determination of pharmaceutical residues in different matrices. Section one of the study underscores the environmental advantages of employing GC for such analyses. Section two presents the innovative methods for determining pharmaceuticals in the environment. The last section discusses the results of the analysis of the GC and GC-MS market in Poland.According to the literature data, the described methods were applied for the analysis of real samples: wastewaters, surface waters, soil samples. The samples were collected from the Pomerania region and the Gulf of Gdańsk. The pharmaceuticals were determined in various environmental samples. The highest concentrations were found in raw wastewater, medium – in a treated wastewater, and the lowest – in surface water. The most frequently detected pharmaceuticals were: ibuprofen, paracetamol, diclofenac and naproxen, all belonging to NSAIDs.Furthermore, the results of the study of the Polish GC market indicate that a very limited number of entities are currently using chromatographic techniques, and pharmaceutical residues tests are exceptions, mainly due to the lack of the legal requirements in this field and the lack of own laboratories.

Currently, due to the growing dynamics of changes that take place in the environment of organizations, managers have to intensify their efforts to implement ‘solutions’ which will not only increase the efficiency of particular business activities, but will also strengthen the potential of the organization in the area of its sustainable development. One of the elements from a ‘wide set of potential solutions’ is risk culture. In spite of a number of studies dedicated to explaining its essence, dimensions and influence, the phenomenon of risk culture has not yet been fully explored. While the previous research and analyses have tended to focus on defining its role and learning about its effects, especially in the financial sector, this study was directed at explaining risk culture in the specific organizational context of implementing sustainable projects in business. This paper analyzes the manifestations of risk culture in sustainable projects, along with its dimensions and key determinants. The authors used the single case study method. In order to expose the Central European context, an innovative Polish enterprise with sustainable project management practices, implementing projects with a high degree of risk, was selected. The results of the study indicate that the main source of risk in the studied projects was the customer. Risk culture in this business entity is characterized by perceiving the variability of customer expectations as an important project risk factor. At the same time, sustainable project management ‘was accompanied’ by a more mature risk culture. The study confirmed that the beneficial impact of the risk culture on the project itself and the enterprise takes place under conditions of the convergence of the risk culture with the organizational culture. Conflicts between project participants, as well as conflicts between the project implementation team and the internal environment of the enterprise, increase the probability that risk culture poses a threat not only to particular projects, but also to the company.

Tourism is a critical economic sector for many countries, making substantial contributions to GDP and job creation. Analyzing performance in this domain has become indispensable for understanding and enhancing its economic, social, and environmental impact while promoting the sustainability and competitiveness of tourist destinations. In the context of the prolonged coronavirus pandemic, the tourism field suffered the effects of a weakened economy and a heavily affected society. For this reason, countries and their tourism industries have been looking for ways to improve performance in this sector by trying to address salient determinants related to investments in this industry. This study employs the input-oriented DEA-CRS (Data Envelopment Analysis–Constant Returns to Scale) model to assess Romania’s tourism performance in comparison to 11 other Central and Eastern European (CEE) countries. This analysis utilizes a dataset comprising three input variables and two output variables, with data corresponding to the year 2023. Half of the countries studied are deemed efficient, while only one is found to have a low level of efficiency in the tourism field. Following the analysis of the obtained results, four reference countries were identified, namely, Estonia, Croatia, Poland, and Slovenia. Practically, within the analyzed model, these four countries represent examples of good practices in the efficiency of the tourism industry for the other eight CEE countries.

Currently, there is a growing number of businesses which organize their operations in the form of projects. One of the key success factors in the area of project management is building successful relationships with project stakeholders. Using stakeholder theory perspective and looking through the lens of family involvement, the study addresses two research questions: 1. how do family firms perceive the difficulty in building relationships with external stakeholders compared to other project management difficulties; 2. does organizing work in the form of projects redefine the significance of family involvement in the difficulties of building relationships with external stakeholders. To answer these questions, 154 Polish family-owned enterprises, considered as representatives of Eastern European emerging economies, were surveyed. The results indicate that family involvement strongly influences the difficulties in building relationships with external stakeholders, but only in those companies which at the time of the survey were not managing projects. In the firms employing project management practices, only the factor related to increasing the number of employees had a facilitating effect on the studied phenomenon. On the contrary, in the case of family firms not managing projects, the growth in the number of employees increased the difficulty in building relationships with external stakeholders. The findings add to the research on the role of family involvement in building relationships with a firm’s external stakeholders.

The objective of this paper is twofold. First, it systematizes knowledge about green management practices as a manifestation of the green human resource management (HRM) concept. Second, it diagnoses the practices of green management in construction companies in Poland. The research is qualitative and was conducted in three construction companies (one large, one medium, and one small-sized). Due to the small sample size, the study is treated as a pilot study. The research concluded that although green management practices are employed in the studied companies, they are neither systemic nor satisfactory in intensity. In the large company, green management practices are visible at all stages of the human resource process except for employee appraisal. In the medium and small companies, green management is limited to the development of green knowledge and employee awareness activities. The added value of this paper is an original tool for diagnosing the level of advancement of green management practices in competence management, which can be used in various types of business entities, regardless of the sector or industry.
