Theoretical classes: Introduction to Environmental Engineering as a discipline (environmental crisis, the symptoms of the environmental crisis, new dimensions of the environmental crisis, the goal of environmental engineering, sustainable development, interdisciplinarity and globality). Basic concepts of general environmental engineering (the concept of system, system boundaries, energy and matter exchange through the boundaries of the system, the Earth as a system, flows, cycles and structures of living systems in environment, the structure of an open environmental system ). Water cycle and global cycles of some chemical elements (Water cycle, chemical elements, circuits, the global carbon cycle in nature, the global sulfur cycle in nature, global nitrogen cycle in nature). Mutual influence of civilization and the environment (the development of cities, demographic explosion, nutrition of the population). The atmosphere, important parameters of the atmosphere and MAC pollutants in the atmosphere (the structure of the atmosphere, the temperature in the atmosphere). Noise as a specific type of pollution (production of sound and its transmission, sources of noise, permitted levels of environmental noise). Sources, characteristics and effects of pollution (air pollution, sources of polluted air, primary and secondary air pollutants, the effects of air pollution, ozone as a problem in the environment, global heating). Basic principles of environmental protection. Practical training (exercise): The exercises are examples of the computation tasks which illustrate topics covered in theoretical teaching, contributing to a better definition, better observation and better understanding of the topics treated in the theoretical teaching.
