Šetření vybraných parametrů zásahů Hasičského záchranného sboru hl. m. Prahy při výskytu oxidu uhelnatého / The survey of selected parameters of the intervention of Fire Rescue Service of Prague in case of carbon monooxide presenceJOB, Lukáš January 2016 (has links)
The association between intoxication by hazardous chemicals and selected parameters response of the Integrated Rescue System is currently a frequently discussed theme. This connection is especially observed where the main source of carbon monoxide poisoning. Fire and Rescue Service of the Czech Republic in cooperation with the Integrated Rescue System units solves a wide range of events every year just with the leakage of carbon monoxide. This gas was, and today still is the cause of much intoxication, especially when using Karma for water heating. That is the reason why this thesis focuses precisely on the investigation of selected parameters response of the Fire and Rescue Service of the capital City of Prague upon the carbon monoxide occurrence. Important factors influencing the progress of the intervention is i.a., knowledge of the toxic effects of this gas and its effects on the human body, but also adequate quantity and quality of the detection devices and protective equipment. This diploma thesis deals with the investigation of selected parameters mentioned above emergency interventions, be subsequently treated by in the period from 2010 to 2014 under the Fire and Rescue Service of the capital City of Prague. The theoretical part describes the hazardous chemical substance (carbon monoxide) in terms of chemical, physical, biological, and also its use. The important part is the detailed description of the intoxication of carbon monoxide in the organism, the degradation of the organism, consequences of poisoning and medical procedures. Further have been also described respiratory protective devices, which are focused on the protective filters. When processing the diploma thesis is also found all events with the release of carbon monoxide in the capital City of Prague territory. These data are based on the statistical monitoring of events that leads and processes Fire and Rescue Service of the capital City of Prague. From statistic of interventions are subsequently searched data on the number of killed, wounded and rescued persons who are within the statistics registered. As comparative parameters are selected data on average daily temperatures and average daily pressures in the capital City of Prague territory. These data are for the period provided by the Czech Hydrometeorological Institute, Prague subdivision. The diploma thesis is determined and verified hypotheses of influence of the average daily temperature on the frequency of interventions with the presence of carbon monoxide in the capital City of Prague territory in the monitored period, average daily pressures influence on the frequency of interventions with the presence of carbon monoxide in the capital City of Prague territory and affect of the average daily temperature on the average daily pressures. The gained information is comprehensively and detailed processed into tables. The events in tables are divided by years, months. Afterwards it provides a general overview of emergency interventions in the monitored period. The processed data are then statistically examined and evaluated. In the first part is determined statistical unit for the period of five years. The data are also tabulated together with the average temperature and the average pressure and then suitably scaled. Then calculation of the general moments of the first order, standard deviations and correlation analysis follows. The results are compared with prescribed intervals. Based on a comparison of the results with the prescribed intervals is evaluated that the number of events does not correlate with the temperature, so the number of events with a temperature not connected, the number of events is positively correlated with the pressure, which means that the number of events related to the pressure. The temperature correlates positively with the pressure, i.e., these two parameters together, purview within performed examination, related.

Využití inovativních sorbentů při imobilizaci Zn v půdě / The use of inovative sorbents for immobilization of Zn in soilŘečínská, Magdalena Unknown Date (has links)
Amorphous manganese oxide has been already successfully tested as an efficient amendment for limiting the mobile fraction of risk elements in soil. However, its application is accompanied with an unsolicited phenomenon of increased dissolution of this agent related to oxidation of soil organic matter. For that reason, surface modification of the studied Mn oxide with the layer of MnCO3 has been proposed (Sm-AMO). The subject of this thesis is to assess the effectiveness of chemical stabilization of two contaminated soils using Sm-AMO with a focus on Zn and to verify the stability Sm-AMO based on laboratory experiments. The results of preliminary stability testing of both materials in demineralized water confirmed that Sm-AMO is less soluble than the original AMO. However, this fact was not confirmed by the results of testing of AMO and Sm-AMO performed using pH-static leaching experiments, when no differences were observed between AMO and Sm-AMO stability based statistical analysis, except for the natural pH (6.03) in the Litavka soil (soil L). Both sorbents yielded greater stability with increasing pH. Adsorption kinetics of Pb, Zn, Cd and As, which are present in the tested soils, onto AMO and Sm-AMO was studied to compare the adsorption properties of both materials. Affinity of these metals was generally higher towards AMO, but the recorded equilibrium time was similar for both sorbents. The results of adsorption kinetics for both materials tested showed the highest sorption rate and the highest adsorbed amount for Pb and the lowest for Zn. Similar results were also observed at pH-static leaching experiment. Stabilization effectiveness of Sm-AMO compared to AMO was mainly demonstrated for Pb and As under natural pH conditions (pH 6,03 and 6,43) of Litavka and Smolotely soils. Considering the stabilization of Zn statistically significant stabilizing effect of AMO/Sm-AMO was observed only at pH 8, when the AMO showed to be more effective. The effectiveness of Sm-AMO for the immobilization of Zn was not as significant as expected, but compared with other immobilization amendments Sm-AMO is an effective sorbent for Zn stabilization.
