Toxicologists assess the adverse, harmful effects that substances have on human health and the environment. Toxic substances can be natural resources such as arsenic and mercury, generated by living organisms such as microorganisms, algae, and shellfish, or generated by humans. Man-made sources include unintentional substances such as pollutants from traffic as well as industrial chemicals or pharmaceuticals. Toxicologists play an important role in making our lives more sustainable, by considering safety when designing new substances or by identifying safer alternatives.
This MSc programme will provide you with an advanced understanding of the multidisciplinary field of Toxicology. You’ll learn about the fundamental principles of Toxicology, the harmful effects that different substances (e.g., chemicals, pharmaceuticals, food, drink, pollutants,) have on human health and the environment, how the safety and sustainability of substances is assessed and improved through design strategies, what regulations exist to protect human health from the harmful effects of substances, as well as topical and emerging issues in Toxicology.
Over recent years, there has been a desire to transition away from animal testing in Toxicology and the generation of data using new approach methodologies (NAMs) means that the knowledge and skills required by toxicologists is changing. You will learn why alternative (non-animal) approaches are being increasingly used for hazard identification to make Toxicology testing more ethical, quicker, predictive, and potentially cheaper when compared to more traditional animal (mammalian) tests.
You will learn how to critically appraise the quality of existing literature and communicate scientific concepts and research findings to different audiences. You’ll gain skills that enable you to work as a Toxicologist in sectors such as academia, Government, and industry to meet the current growing global demand for trained Toxicologists. The UK currently tackles the regulations and policies related to substance safety, which was previously provided by the EU pre-Brexit, and is desperately seeking trained Toxicologists. The knowledge and practical skills you will gain through this master’s degree, will make you highly sought after upon graduation.
