Proper environmental project management is a significant element in shaping a positive, pro-environmental image of urban agglomerations and adjacent towns. Environmental resource management and protection, as well as spatial planning in accordance with sustainable development principles, are the most important factors in creating a positive image of, and strategies for, cities. An example of a large, innovative environmental project implementation is the Central Sewage Treatment Plant in Kozieglowy, in the agglomeration of Poznan, and its installations and equipment impact assessment studies. Important aspects of the project were mediations, which took place from May 2011, until the end of April 2012.
We studied climate change dynamics in southwestern Poland. The authors based the assessment of dynamics on the results of flood risk analyses. 30-day flow maxima were selected for three 10-year periods based on hydrological data on daily flows from 1986 to 2015 from the hydrological station on the Oder River in the town of Malczyce. By utilizing the selected maxima as well as selected maximum value distributions, probabilistic models of extreme flows were constructed for the three studied periods – each divided into six-month periods of “summer” and “winter.” The estimated models were used to calculate measurements of flood risks in the analyzed periods. We analyzed the studied area on the basis of the results the dynamics of flood risks.
We carried out a probabilistic analysis of the dynamics of flood risks for the selected area of the Oder River basin. The authors based their risk dynamics assessment on results from the distributions of the maximum values for a selected hydrological characteristic, namely flow rate. On the basis of the daily flow data from 1994-2013 collected at a hydrological station on the Oder River in the town of Malczyce, 30-day flow maxima were selected individually for four five-year periods. Then, a probabilistic model of maximal flow was estimated on the basis of these peaks for each five-year period. The resulting models were used to estimate flood risks and analyze the dynamics of the studied area.
Przedstawiono charakterystykę metody pomiaru stężeń zapachu oraz urządzenia do poboru próbek odorotwórczych gazów. Przytoczono przykład zmierzonych stężeń zapachu dla wybranego źródła przemysłu rolno-spożywczego. Opisana metodyka jest zgodna z normą PN-EN13725 oraz wytycznymi VDI 3880 opracowanymi przez Zrzeszenie Inżynierów Niemieckich.
The aim of this study was to evaluate the impact of a sewage treatment plant on the occurrence of gastrointestinal symptoms among the local residents. A survey was conducted on two populations: one from the vicinity of the sewage treatment plant (the exposed group: 586 people), and the other from outside the impact area of the plant (the control group: 502 people). The research area was divided into distance zones from the plant (A, B, C). The questionnaire included questions about the occurrence of gastrointestinal disorders. Compared with the control group, the local residents reported more often: nausea, vomiting, and frequent diarrhea. Occurrences of gastrointestinal disorders were associated with air pollution by pathogenic staphylococci (OR~7) and odours (OR = 7.34; Cl 3.43-15.72) emitted by the plant, and also living in zone A vs. zone C (OR = 3.47; CI 1.00-12.07), use of a gas cooker in houses (OR = 2.21; CI 1.03-4.70), and the age of the respondents (0.98; CI 0.96-1.00). The study showed that as distance from the plant increased, the incidence of reported gastrointestinal disorders declined. Living in the vicinity of a sewage treatment plant favours the occurrence of gastrointestinal symptoms among the local residents.
