Opis:: Introduction: Nosocomial (also known as hospital-acquired) infections are understood as infections which develop during patient’s stay in hospital, but are not the direct cause of hospitalisation. The aim of the study: The purpose of the paper was to determine the knowledge of the nursing personnel from Świętokrzyskie Voivodeship onnosocomial infections, prevention and methods of combating them. Other addressed issues included the analysis of the work yeas and education level as related to the state of nurses' knowledge on nosocomial infections, and what are the reasons for insufficient prevention of diseases. Material and methods: The study included 208 nurses from Świętokrzyskie Voivodeship. Out of 208 questionnaires, 180 were completed correctly, the remaining 28 were answered incorrectly or incompletely, which resulted in their rejection. The statistical analysis was conducted using the Pearson Chi-squared method, with the significance level p>0.01 assumed to be insignificant. The study involved 124 women and 56 men. The youngest respondent was 23 years old and the oldest was 59 years old. There were 36 respondents below 30 years of age(20%), 88 in the 31-40 age group (48.9%), 56 in the 41-60 age group (31.1%). Results 1. The knowledge of the intermediate personnel about hospital-acquired infections is satisfactory. 2. Job seniority is not statistically significant with regard to the knowledge level on nosocomial infections. 3. The research revealeda statistically significant correlation between the knowledge level of the secondary staff and their education. 4. The study results show that the most common causes of insufficient knowledge on preventing hospital-acquired infections are staff shortages and inadequatefinancial resources.

Opis:: The rapid growth in the production and use of nanomaterials is observed in recent years. Nanoparticles of titanium dioxide (TiO₂NPs) are one of the most frequently used nanomaterials. Sunscreens, food additives, food contact materials and textiles are the major fields of current application of TiO₂NPs. Due to increasing use of nanomaterials in daily life and thus increasing exposure to them, concerns have been raised about their safety. Likely routes of human exposure to released TiO₂NPs as well as their health and environmental effects are presented in this paper. At present, our knowledge about the risk of nanomaterials is incomplete. However, it is known that toxicity of nanoparticles depends on their size, shape, crystal structure, surface morphology, surface area, charge, concentration and solubility (the possibility of dissolution into ionic forms). Therefore, it is necessary to use several complementary analytical techniques to fully characterize the NPs. Common approaches used for the characterization of nanomaterials include microscopy based techniques e.g. transmission electron microscopy (TEM), X-ray techniques e.g. X-ray diffraction (XRD), methods based on optical properties e.g. dynamic light scattering (DLS). Separation of nanoparticulate and ionic forms of metal can be accomplished using chromatographic techniques (such as high performance liquid chromatography (HPLC), size exclusion chromatography (SEC), hydrodynamic chromatography (HDC)) or capillary electrophoresis (CE). Size-resolved NPs and dissolved (ionic) fractions can be further characterized by on-line detectors, such as ICP MS. Recently, single particle inductively coupled plasma mass spectrometry (sp ICP MS) has been gaining increasing attention as a technique for detection, characterization, and quantification of nanoparticles. This technique provides information on individual particles, including particle size, number size distribution, particle number concentration and mass concentration. In addition, sp ICP MS can distinguish dissolved and nanoparticulate forms of an element. The fundamentals, advantages and limitations of this technique, as well as its application for the characterization and quantification of TiO₂NPs in different matrices (consumer products, food and environmental samples) are reviewed in this paper.
