Course programme

Environmental Biology course is designed to provide fundamental ecological principles
that provide a in-depth understanding of our natural world, the scientific basis for understanding
how environmental systems work, the environmental issues, environmental problems, effects and
solutions. This course also provides detailed information about environmental toxicology, which
provides a sound basis for understanding and formulating various measures to protect the health
and welfare of human population in the world. The course content of this paper is designed to
give a basic understanding of various aspects of environmental toxicology.
