Learning outcomes - To monitor environmental pollution and preserve ecosystems and natural resources; To study the chemical and toxicodynamic behaviour of substances in the environment, risk assessment and deleterious effects; Report on preventing the harmful environmental effects and damage repair.
Before the completion of this course students should be able to:
- To describe the main techniques involved in the use of living organisms on detection and bioremediation of the contaminants and to define bioremediation methodologies, in particular those related to microbiology, through a case study approach. Understand the environmental impact of toxic substances, and their direct and indirect relationship with the human health; Understand the role of contaminants in the environment, their bioaccumulation and their effects; Evaluate the basic toxicological parameters and their laboratorial determination;
Syllabus T1 – Environmental Biotechnology
