Methods for the determination of radiological impact of the food chains
Tesař, Jakub ; Bartusková,, Miluše (referee) ; Havránková, Barbora (advisor)
The diploma work presents comprehensive overview of methods of determination of radiological impact on food chains. It describes the determination of radionuclides in groceries in common radiation situation and in unusual radiation situation. Practical part of the work presents two model radiation events. These are radiation event in the territory of Czech Republic and radiation event in the territory of other country and its impact on Czech Republic. In the end both model situations are compared.

Mikroplasty v mořských plodech a jejich dopad na lidské zdraví
Formanová, Michaela
This bachelor thesis summarizes current knowledge regarding the accumulation of microplastic particles in the marine fauna and their impact on marine organisms. The uptake of microplastics has been demonstrated in laboratory and natural conditions in various marine organisms, including zooplankton, oysters, mussels, and shrimp. Microplastic particles are transferred from lower to higher taxonomic levels through the food chain via trophic transfer. The model transport within the food web was studied in a marine crab that was fed with mussels contaminated with microplastics. Microplastic fragments were able to penetrate from the crab's gastrointestinal tract into surrounding tissues. Microplastics are receiving a lot of attention in research as potential carriers of dangerous chemicals. The consequences of microplastic contamination on the food chain and human health are not sufficiently explored and require further study.

Food waste in Czech republic (regional aspects)
MAURICOVÁ, Aneta
e main aim of bachelor´s thesis is to realise theme of food wastage, both in the context of sustainable development and from the point of view of the general 'resources' of waste and the Czech Republic. Areas of uneconomic food use will be identified and an option of their alternative use. The main method which will be used is literary research. The practical work will be devoted to surveys at household level at the final consumer. By using an analytical approach to evaluating collected data, answers to questions on consumer wastage issues will be obtained. The work also deals with the reduction of food waste in all parts of the food chain - from primary production to household. It also deals with food banks. Further, there are presented the impacts of the waste, and the legislation is mentioned at the border. Finally, there are activities against wastage and some examples of solving this problem both in the world and in the Czech Republic.

The issue of food waste
Vozábová, Aneta ; Cimler, Petr (advisor) ; Hommerová, Dita (referee)
This thesis deals with the issue of food waste from the global perspective. The aim of the thesis is to summarize this issue from available world sources and on the basis of its own experience from the practice in public catering facilities. The thesis defines areas of food waste within food chain, identifies the economic, social and environmental consequences resulting from careless food handling and describes organizations and companies dealing with the prevention of food wastage. There are recommendations for the prevention of food waste in households. The practical part of the thesis analyzes food waste in Czech households, measured for one week.

Regulation of retailer-supplier relatiohships within the food chain
Mokrejšová, Veronika ; Zadražilová, Dana (advisor) ; Klosová, Anna (referee) ; Zeman, Jiří (referee) ; Vyhnálek, Petr (referee)
This thesis deals with retailer-supplier relationships within the food chain, and with possibilities of their regulation. The aim is to assess the effect of regulation of retailer-supplier relationship, through "Act on Significant Market Power and Abuse thereof" on particular food chain members, and eventually to propose an alternative solution of their regulation. The thesis states the following hypothesis: The Act on Significant Market Power does not change bargaining power between suppliers and retailers. The thesis is divided into five parts. The first of those defines the issue of retailer-supplier relationship, especially the so called "unfair practices". The mind-set of the European Commission which judges the unfairness of a practice, according to its impact on consumer, investment and competition is stressed. When comparing market shares and profit abilities, it is obvious that supplier sector is not disadvantaged in relation to retailing, however, there are cases of small and medium enterprises over which retailers can impose their bargaining power. Retroactive changes and excessive risk transfer on a business partner are then indicated as unfair, which is confirmed by microeconomic analysis. The second part maps means of regulation, through hard and soft law in the EU and its member states with focus on the Czech Republic, where the Act No. 395/2009 Coll., on Significant Market Power in the Sale of Agricultural and Food Products and Abuse thereof is applied. It is found that regulation within the EU is heterogeneous and the results of different regulatory mechanism in different countries differ. The third part talks about self-regulatory possibilities constituted by corporate social responsibility. The main solution of retailer-supplier relationships is represented by stakeholder dialogue, in which contractual parties look for the basis of their antagonistic positions (which are hidden in their interests and needs), and try to identify mutual needs and to create shared value. This approach increases the created value, which is advantageous for both partners, instead of redistributing the value to the benefit of the stronger partner. The fourth part presents the results of a survey conducted among retailers, retailer suppliers and farmers, their opinions about the Act on Significant Market Power, about changes caused by this Act and about particular unfair practices. It was realised that the Act does not help the suppliers very much, in that the bargaining position was improved only with a tiny part of the respondents, and the Act even did not fulfil the role of small and medium sized enterprises protection. The everyday practice of retailer-supplier relationships remains (after changing few legal formulations in the contracts) almost the same as it was before the Act came into force. The only considerable change is shortening the payment period to 30 days; however, there are suppliers that are not content about this provision. The farmers do not feel any consequences of the Act; retailers regard it as business barrier and excessive regulation. Thus, this part confirms the hypothesis. The final part of the thesis proposes a solution to this issue by engaging many stakeholders: the business partners (self-regulation), the State (regulation through general universal act), consumers, non-governmental organisations and media (generating demand for responsible behaviour of firms).
