Marečková, Kateřina ; Vávrová, Milada (referee) ; Čáslavský, Josef (advisor)
Pesticides and their excessive use lead to environmental pollution. Violation of the guidelines for their use disposal of empty containers could lead to contamination of water, soil and poisoning of animals and beneficial insects. Honey bee is useful creature on our planet. Good farming depends entirely on the pollination, but whole vegetal kingdom couldn’t exist it form known and used by mankind. Therefore, rules that protect these useful creatures against inadequate use of pesticides have been developed. This study focuses on the evaluation of the possibility to use bee products as bioindicators of the state of environment. Five active substances which are components of pesticides used in the treatment of agricultural field around Tasovice village were analysed in the pollen and honey. For sample preparation QuEChERS and SPE methods were used, gas chromatography with to mass spectrometric detection was employed as final analytical technique.

Utilization of bees products in cosmetics
Kobza, Martin ; Bednář, Michal (referee) ; Zemanová, Jana (advisor)
This bachelor thesis is focused on the problem of utilization of bees products in cosmetics. The aim of this thesis was to elaborate a literature review focused on individual bee products, their properties and their utilization in cosmetics. Honey, beeswax, propolis, pollen, royal jelly, apisin are said to be the bee products. Properties, utilization, determination of kvalitative properties and aplication into cosmetic products of individual bee products are mentioned in this thesis. Beeswax is used in production of lipsticks, creams and for basis of smears (oily creams). Royal jelly is aplicated into lotions, face masks, lipsticks, night creams, hair waters, hydration preparations etc. Honey is used for preparation of shower gels, soaps, body milks, hydration creams. Propolis is added into creams, body milks, body lotions, shampoos, lipsticks, soaps and mouth sprays. Pollen has significant content of vitamins, aminoacids and other substances in nature form for cosmetics. These substances are important for nutrition, regeneration and hydration of skin. Apisin is used in pharmacologic preparations, like healing creams and smears.

Representation of bee products in the nutrition of adults in the Czech Republic
ZÁHORKOVÁ, Jana
Currently at the forefront of people's healthy eating and healthy lifestyle. Bee products are a source of healthy nutrition. In the framework of representation of bee products in the nutrition of adults in the Czech Republic was through a questionnaire addressed a group of 1,086 persons age structure over 18 years old, living permanently in the Czech Republic. It was found that the best known bee products in the adult population include honey (99 %), the second most famous product is the beeswax (93 %), and knowledge of other products gradually decreases in the number of propolis (81 %), royal jelly (77 %) pollen (59 %), bee venom (45 %), bee brood (22 %). The most common honey bee products. Its consumption is 0.6 to 1 kg / person / year, when its consumption rises in interest groups, such as the beekeepers to 1.5 - 5 kg / person / year and more. The most common use of honey is its direct consumption, which is the preferred liquid consistency and type of honey - blossom (nectar) honey.

Výzkum původu prachu v exponovaných oblastech pro programy zlepšení kvality ovzduší
Vysoká škola chemicko-technologická v Praze ; Český hydrometeorologický ústav, Praha ; Technické služby ochrany ovzduší Praha a.s. ; Reiserová, Jana ; Suchánek, Miloslav ; Stárková, Běla ; Novák, Jiří ; Bureš, Vladimír
Cíle projektu je výzkum charakteru a původu prachu, jeho kvantifikace a kvalifikace - tzn. množství a rozměry prachu a jeho chemické složení. Dále výzkum rizik a dopadu na lidské zdraví, návrhy progresivních metod na snížení množství prachu v ovzduší v exponovaných oblastech, identifikace zdrojů znečištění na základě měření imisí, analýzy mikroskopické a chemické; určení obsahu pylu a dalších biologických materiálů, určení zdrojů emisí prachu za pomoci zpětného modelování, řešení souvislostí mezi původci znečištění a návaznost na možné ohrožení citlivými organismy v prostředí. V r. 2001 byl proveden výběr lokalit pro odběr vzorků, instrumentace odběrů imisních vzorků pro aplikaci modelu, anorganická chemická analýza vzorků, organická chemická analýza vzorků, mikroskopická analýza vzorků a příprava na receptorové modelování.
