Assessing levels of endocrine disrupting steroid hormones in Swedish waters (Master)
The overall objective of this Master thesis is to assess the occurrence and release of endocrine disrupting steroid hormones in Swedish waters.
In recent years, there has been an increasing concern about the presence of steroid hormones in the aquatic environment. Some of these hormones, such as 17α-ethinylestradiol, have been considered as contaminants of emerging concern under the European Watch List in 2015.
Since low levels of steroid hormones can exhibit endocrine malfunctions of aquatic organisms, data on their occurrence in water bodies are important to suggest and develop new treatment options for reducing their release into the environment. Incomplete removal of steroid hormones at wastewater treatment plants poses a threat to aquatic organisms. Therefore, monitoring of these chemicals in wastewater effluents and receiving waters allows to evaluate their negative impact on the quality of our water environment.
The overall objective of this Master thesis is to assess the occurrence and release of endocrine disrupting steroid hormones in Swedish waters. From this project, the Master student will acquire knowledge from development and validation of analytical methods to water sampling, sample preparation and data evaluation. The work will be performed under the supervision of experienced environmental and analytical chemists.
