    Opis:
    Water quality control from the perspective of water supply system users’ safety contributed to create drinking water production and quality control procedures. Contemporary risk hazard analysis should be performed on the stage of production, distribution and storage of tap water. Sequences of undesirable events are considered in the so-called waterworks chain series. This leads to critical control points and gives the ability to provide current control over the processes in the collective water supply system, as well as of their combinations and mutual interactions. Methodology of water consumers protection against incidental pollutions was shown. Algorithm concerning identification of critical control points – CCP was developed .The rules of safety related system into drinking water production have been shown. Also risk assessment using the tree event method was presented.

    Opis:
    The 35.4-km stretch of the A8 motorway, i.e., Wrocław’s motorway ring-road (WMRR), passes through the north-west part of the city of Wrocław and 4 neighbouring districts. Analyses have shown that WMRR will be a source of noise in the environment, which may adversely affect large areas. Normative environmental protection acts mandate taking all the necessary technical and organizational measures to reduce noise generated by the operation of WMRR in order to comply with the acoustic environment quality standards. The paper presents the research methodology adopted for assessing noise impact and designing acoustic barriers, and proposed designs of acoustic barriers which take into account the acoustic requirements, technical limitations, urban development, and architectural conditions.

    Opis:
    A constant growth of interest in GSCM on the part of business practitioners creates a need to develop research within this field. One of the basic questions is why, despite numerous evidence of benefits resulting from the use of pro-environmental practices in supply chains, the level of GSCM implementations is low. Therefore, the aim of the paper is determining which barriers constitute the greatest obstacles on the way of GSCM implementation. The studies were conducted among Polish market entities. Therefore, they were prepared in the part of Europe in which there are not many studies regarding this topic. As a result of the conducted studies, it was determined that the greatest barriers for pro-environmental practices are included in the field which concerns knowledge and cost. What is more, the importance of particular barriers was specified in the paper.

    Opis:
    The near-surface “RADON” type radioactive waste repository, installed in 1963 and designed to store radioactive waste formed in industry, medicine and scientific investigations, was closed in 1989 because it did not meet the requirements imposed on the radioactive waste disposal. A comparatively small amount of radioactive waste is stored in this repository, but the inventory comprises various kinds of waste: short-lived low-level radioactive waste, short-lived low and intermediate radioactive waste, long-lived intermediate and high-level radioactive waste. The possible site-specific radionuclide migration through the groundwater pathway as well as the human exposure are considered by the computer program RESRAD-OFFSITE in this paper. The analysis of the obtained data shows that out of all stored radionuclides only H-3, C-14 and Cl-36 exceeding the dose constraint of 0.2 mSv can be considered as dangerous. The monitoring carried out in the repository environment has shown the contamination of groundwater with radioactive tritium and a significant reduction of contamination after construction of additional protective engineering barriers. For the assessment of the contribution of separate site-specific parameters of the model taking into account uncertainties of the model and parameters to the annual effective dose, the computer code RESRAD-OFFSITE provides the possibility of applying the regression analysis. It has been determined that the aquifer lateral dispersion as well as the hydraulic gradient, the radionuclide activity concentration in the repository together with the rate of penetration into the environment and the precipitation amount have the largest influence on the assessment accuracy of annual effective doses.
