Mapování výskytu (anti-)progestagenních aktivit v povrchových vodách České republiky
KRULOVÁ, Jana
The aim of the bachelor thesis was to map the occurrence of substances with (anti-)progestagenic activity in surface waters of the Czech Republic. Samples were taken at 21 localities using POCIS samplers. Localities included the so-called closure profiles (end of the river basin) and significant sampling points along the profile of the river Elbe. The samples were transported to the laboratory, where they were extracted. (Anti-)PR-CALUX in vitro bioassay was used to detect (anti-)progestagenic activity. First, the cells were plated on a microtiter plate and, after 24 hours of incubation, exposed to a calibration series of the reference substance ORG 2058 for progestagenic activity or the reference substance mifepristone for anti-progestagenic activity and a series of diluted surface water extracts. After 24 hours of exposure, cell luminescence was measured in relative light units. The resulting hormonal activity was expressed in ng/l equivalents of the reference substance (ORG 2058 or mifepristone). Progestagenic activity was below the limit of quantification in the samples from all 21 sampling sites (<6-11 ng/l ORG 2058 equivalents) sampled in the year 2017. Anti-progestagenic activity was detected at 6 localities, ranging from 12 to 33 ng/l mifepristone equivalents. For comparison, 3 samples from the year 2016 were analysed. Anti-progestagenic activity was detected in the range from 14 to 48 ng/l mifepristone equivalents. Progestagenic activity was below the limit of quantification at all 3 localities. The occurrence of anti-progestagenic activity was detected mainly at localities where the chemical industry is in the vicinity. There are companies that can use certain substances with anti-progestagenic activity in the production of their products, such as polycyclic musk compounds, brominated flame retardants or bisphenols. The occurrence of anti-progestagenic activity in these localities could indicate the insufficient ability of industrial wastewater treatment plants to degrade substances exhibiting anti-progestagenic activity. The occurrence of anti-progestagenic activity in surface waters may have a negative impact on aquatic organisms, especially vertebrates. Exposure of these organisms to substances with anti-progestagenic activity could lead to reduced fertility and impaired gonad development.

Diplomová práce se zaměřuje na působení britské Východoindické obchodní společnosti v Indii. První kapitola shrnuje okolnosti vzniku a působení Společnosti na indickém území před rokem 1756. Následná kapitola popisuje přerod Společnosti jako monopolní firmy v suveréna na indickém subkontinentu. Teoretická část práce se věnuje přístupu předních britských ekonomů té doby k otázce kolonií a Společnosti samotné. Hlavní část práce analyzuje nositele, nástroje a financování hospodářské politiky Indie v době vlády Východoindické společnosti. Zabývá se vztahy britských politiků k indické otázce a jejich vlivem na formulaci hospodářské politiky. Analyzuje hlavní nástroje politiky Společnosti v Indii jako jsou obchodní monopol a armáda. Podrobněji sleduje financování, příjmy a výdaje Společnosti v době její vlády. V závěru nastiňuje některé okolnosti konce vlády Východoindické společnosti na subkontinentu.
