The study of PET bottles in terms of the content of risk elements
Kryštofová, Petra ; Řezáčová, Veronika (referee) ; Komendová, Renata (advisor)
This bachelor thesis deals with the issue of PET bottles in terms of the possible content of risk elements. The contents of antimony, copper and lead were determined in the PET packaging material and in the beverages contained in the bottles. A total of 15 samples of bottled still and infant water available in the Czech sales network were analyzed. The PET material was decomposed in an acidic medium under the action of microwave radiation under optimized conditions. Atomic absorption spectrometric methods with flame or graphite cuvette atomization were used to determine selected risk elements based on the predicted analyte concentrations. In the PET packaging material, 159.35 to 265.68 mgkg-1 of antimony were determined, the determined values of lead concentration were in the range of 10.96-20.23 mg·kg-1 and the copper concentration in the range of 0.11-7,52 mg·kg-1. In bottled water and in bottled infant water, antimony was identified only in samples labeled 6a, 8a, 9a and 15a, all lead concentrations were measured below LODPb, copper was determined only in samples 2a, 6a and 8a. In none of the samples did the concentrations given by the valid legislation be exceeded. The limits of these metals are not set in legislation in the packaging materials, only specific migration limits and they have not been exceeded. However, the high concentration of antimony in PET poses a potential risk of contamination of the contents of these packages.

Campaign of the company Veolia Voda "Čerstvá kohoutková? Stačí říct!"
Jindrová, Eliška ; Hejlová, Denisa (advisor) ; Shavit, Anna (referee)
This bachelor thesis Campaign of the company Veolia Voda "Čerstvá kohoutková? Stačí říct!" presents an analysis of a campaign focused on promotion of tap water supply in restaurants. The aim is to present communication activities and creative processing of the project and also to show the perception of the campaign from the point of view of the proprietors of Prague gastronomical enterprises participating in the project based on a survey. The emphasis is put mainly on description of the marketing and communication mix, performed by the descriptive method. Connection between the topic of tap water promotion and the consumption of bottled water and other ecological problems in relation to obtaining drinking water are also mentioned, as is the situation of the tap water usage in restaurants in foreign countries. Media coverage of the campaign is also included in the thesis, followed by a final evaluation.

Green purchasing: Case of Bottled Water Consumption in the Czech Republic
Hanusová, Klára ; Ščasný, Milan (advisor) ; Opatrný, Matěj (referee)
To tackle various environmental issues, many of which stem from unsustainable consumer behavior, policymakers make an effort to transition toward a circular economy. One of the initiatives in the Czech Republic includes a reduction in single-use plastic waste. An example of this waste category are plastic bottles used for beverage packaging. Consequently, this thesis aims to uncover the determinants of bottled water consumption in the Czech Republic, as a similar study does not appear to exist in this context. Data (n=3 411) used for the analysis are obtained from a survey "TAČR Kohoutková". Methods used include estimation by Generalized Ordered Logit and Multinomial Logit. Results uncover socio-demographic characteristics, taste, health reasons, constructs from the Theory of Planned Behavior, and habits as predictors of bottled water consumption. It was found that highly educated people and those with a strong habit of drinking tap water are less likely to consume bottled water. The main consumers of this product appear to be those who negatively perceive tap water taste and healthiness, or positively perceive such characteristics of bottled water. On contrary, there is not enough evidence for identifying a relationship between environmental values and bottled water intake.

MARKETING RESEARCH OF SELECTED COMPANY
DUSPIVOVÁ, Jitka
The theme of my bachalar thesis was Marketing research of the Consumers of a selected company. The firm was the manufacturing corporation HBSW Inc. Byňov. The aim of the thesis was the exploration how the consumers act on purchase of bottled water, and the comparison of the consumption of bottled water in the summer time and in the winter time. I solved the questions e.g. what influences the end user (for example: price, flavour, advertising, packaging) and farther structure of the end user (for example: age, employment, sex or educatio). I studied the professional books and the digest of these books is in the second part of my work. The questionary had twenty-one questions. Sixteen questions appertained to the shopping behavior and consumer behavior, five questions appertained to the consumer. I used the questions with an opened end and the questions with a closed end. The obtained information was processed in the computer programme Microsoft Excel. I ascertained what new flavours would the consumers like, which flavours are the most popular, how to change the consumption of the packaged water depending on the season. All is described in the fifth part this thesis. After the data evaluation and data presentation I suggested the solution for the selected company.

Změny mikrobiologických parametrů balených minerálních vod při nestandardním zacházení
Böhmová, Martina
The topic of my diploma thesis is Changes of microbiologic parameters of packaged mineral waters during non-starndard manipulation.Firstly is clarify what mineral water actually is and what is its dividing. Other chapters of literary summary are focused onpacked water from ordinance number 275/2004. After that it focuses on microbilogy of packaged water where are the microbiological contaminants and also impacts that growth and microbiological reproduction impact. There was made an experiment at the end of diploma thesis at chosen packaged water. In this experiment was made total number of microorganism which was in the process cultivated on 36 °C and 22 °C. Everything was done after its verification and after that were consumed. All the samples were kept in condition as is defined. This research was completed with questionnaire focused on consumation of packaged water and its further storing.

Balené vody v prodejní síti ČR z pohledu minerálního složení
Kilianová, Iva
This thesis deals on bottled water brands available in the Czech Republic and their mineral content. The theoretical part looks into different types of bottled water and their characteristics in accord with regulations given by the Ministry of Health (decree 275/2004 Sb). It also deals with various anions and cations shown on the labels of bottles and their impact on human health. The practical part summarizes information obtained from the bottles sold in widely known stores. The results are entered into tables and charts and are compared with the limit and recommended values defined by the Ministry's regulations.
