Abstract:
Without any doubt, endocrine-disrupting compounds (EDCs) represent an environmental risk for wildlife and human beings. Endocrine-disrupting effects were found for many chemicals in products for personal use, industrial compounds, even in classical persistent organic pollutants (POPs) and many other new emerging pollutants. In order to understand the risk of EDCs associated with their presence in the environment, it is highly important to investigate real risks regarding their fate. The major problem is a lack of standard ecotoxicology assays and mainly interpretation of the results obtained by the tests. The main aim of this PhD project is optimization of existing assays and processes of results evaluation and their interpretation. The project will focus on model artificial contaminated as well as real environmental samples. The project will also include monitoring of the real risks with respect to the presence of EDCs in the environment including actual concentrations, activities and degradability of EDCs. The innovative part of the project consists in involvement of novel models of mixture toxicology, advance analytical techniques and wide battery of bioassays.

Abstract:
The soil contain three times more carbon than atmosphere is essential for nutrient cycling, clean water provisioning and harbour tremendous biodiversity. The ongoing global change and population growth is likely to put increasing strain on the soil ecosystems worldwide and, consequently, profoundly impact ecosystem services that support human society. The aim of the thesis will be to focus on three major form of anthropogenic pressure, agriculture, mining and urbanisation in tropical environment although temperate mirrors will be also considered. Methodically the study will be based on gradient studies and manipulation experiments. Successful candidate should have experience with data collection in field, should have experience with soil biology or soil chemistry or other relevant field and should be familiar with statistical processing of complex experiments. Eexperiences with work in tropical parts of the word and ability to work in multicultural environments are welcome. Good ability of expression in English written and spoken is expected.
