In the present scenario, the major concerns to our environment and its toxicity have raised a great interest globally, especially for the younger generation. With spreading networking of mutagenic factors in the environment, every individual is exposed to different chemicals and fine particles, which may react with our genetic material and may cause myriad health issues. The fundamental questions on the effects of environmental toxicants and pollutants mainly focus on the multidisciplinary field of science by applying the basic principles of physics, chemistry, and biology. We are all surrounded with various natural and man-made environmental toxicants, mutagens, and infectants, which may present significant risk to human health. The global industrialization together with the development of our health system has led to an exponential growth in the number of toxic chemicals used for different purposes. There are varieties of chemical, physical, and biological contaminants that are present in the environment. These toxicants are mainly heavy metals, toxic chemicals, compounds, tobacco smoke, nanoparticles, pesticides, viruses, radiations (ionizing and non-ionizing), and several others (fine particles, pollutions, climate change). These toxicants are highly associated with our daily life and affect our health. In principle, any exposure to these toxicants may induce oxidative stress and start producing free radicals within the cells and may eventually cause severe diseases such as neurological disorders and cancer. It would not be entirely incorrect to assume that the oxidative stress is the root cause of most of the severe health conditions.
