1.Fundamentals of Air Pollution. (2014). United States: Elsevier Science. :- The book Fundamentals of Air Pollution focuses on air quality and pollution control. The meteorology of air pollution and the behavior of the atmosphere are discussed in this book, which distinguishes air pollution from other areas of environmental management and protection. 2. Singh, S. (2018). The Great Smog of India. India: Penguin Random House India Private Limited. :- Every year, air pollution kills over a million Indians, although silently. Families are thrust into a downward spiral of hospital visits, serious illness, and financial difficulties, all of which have an influence on their productivity and capacity to participate in the economy. Children born in high-pollution areas have irreversibly impaired lung function and cognitive capacities, which will have a long-term impact on their earnings. They're all suffering in silence. Every winter, the Great Smog of India falls and envelops most of northern India, exacerbating the problem. During this time, simply breathing has the same health effects as smoking a pack of cigarettes every day. The situation is so serious that emergency health recommendations are in effect, prohibiting residents from leaving their homes. Hence, this book discusses about the urgency and rising menace of air pollution in India. 3. Asian Atmospheric Pollution: Sources, Characteristics and Impacts. (2021). Netherlands: Elsevier Science. :- This book gives a succinct yet thorough study of all areas of pollution and air quality monitoring in Asia. This book focuses on significant places throughout the world and describes a wide range of sources, their transport mechanisms, long-term variability, and climatic implications at local and regional scales. It also covers pollution feedback, as well as feedback on other meteorological parameters such as radiative forcing, fog forms, precipitation, cloud features, and more. It includes sections dedicated to treatment of pollutant sources, studying of pollutants and trace gases using satellite/station-based observations and models, transport mechanisms, seasonal and inter-annual variability, and impact on climate, and it draws on the expertise of multiple well-known authors from various countries to highlight some of these key issues.

Air condition in Rajasthan
National air quality index:

Contemporary air condition of 8 major cities in Rajasthan

(National air quality monitoring programme data of 2020):

^*_{Data given is an average of all the air quality monitoring stations present in the district.}
The above data clearly indicates the dire situation in Rajasthan.
The impact of air pollution is such that it has grave adverse consequences on health of the populace. As per a health survey report, more than 90,000 people who died in 2017 in Rajasthan were linked to air pollution. According to a 2020 study of health and economic pollution published in the journal Lancet, more than 113 million people in Rajasthan died from air pollution in the 20^th year. This is 21.2% of the total deaths reported from Rajasthan in 2019 and is more than the national average of 18%. The number of deaths caused by air pollution is the total number of deaths caused by existing particle particles, indoor air pollution and moderate ozone depletion. In Rajasthan the death toll from pollution has risen to 58,167, while 49,352 deaths have been caused by indoor air pollution and more than 2000 deaths have been caused by ozone depletion.
Reasons for concentration of air pollution in some cities is because the economic geography of Rajasthan is concentrated in 4 regions i.e., Jaipur, Bhilwara, Udaipur and Ganganagar. These contribute over 70% of Rajasthan’s industrial output. These regions consist of key districts of Ajmer, Alwar, Barmer, Bharatpur, Bhilwara, Bikaner, Bundi, Chittorgarh, Jaipur, Jodhpur, Kota and Udaipur, making these most polluted.

 Prominent case laws for protection against air pollution
There are many judicial precedents regarding protection of environment, some of the prominent cases for protecting air and environment are-
M.C. Mehta vs Union of India (1986) also known as the Oleum Gas Leak case. In this case there was a leakage of a deadly poisonous gas (methyl isocyanate) from Union Carbide Corporation India Ltd., located at Bhopal, Madhya Pradesh. It claimed more than 2250 lives and caused serious injuries and long-term ailments to more than 6 lakh people. Within one year of this tragedy another leakage took place from Shri Ram Foods and Fertilizers industries. The Supreme Court keeping in mind both the instances devised the principle of absolute liability. Pursuant to recommendation the Government of India passed the National Environmental Tribunal Act, 1995 to deal with cases of environmental pollution.
M.C. Mehta vs Union of India (1991) also known as the Vehicular Pollution case. M.C. Mehta approached the court under Article 32 lamenting about the deteriorating air condition of Delhi due to unsafe businesses running in highly populated areas of Delhi. The petitioner also grieved about the need for regulation of air contamination by vehicles and power creating units. The Supreme Court said that it is the constitutional duty of the State under Article 48-A of DPSP to protect and improve the environment at the same time it is also a fundamental duty of an individual under Article 51A (g) to protect and improve the natural environment. Supreme Court also said that creating awareness amongst the masses is the most important step in protecting the environment. This judgement had transformative effect and made Delhi the first city in the world to have complete public transportation running on CNG.
M.C. Mehta vs Union of India (1996) also known as Taj Trapezium matter. The contention of the matter was the change in color of the marble of taj Mahal from whitish to yellowish and blackish due to the surrounding pollution created by industrial/refinery emissions, vehicular traffic, brick kilns and generator sets. Supreme court held that Taj Mahal is a UNESCO world heritage site and a huge source of revenue for the nation. It is a masterpiece and has huge admirers worldwide, hence, there will be no compromise with its beauty. The court applied the principle of sustainable development also recognizing the importance of polluter pays principle and the precautionary principle.
Murli S. Deora vs Union of India and others (2002), Tobacco has proved to be one of the deadliest elements in increasing the disease burden of our nation. WHO has estimated almost 7 million deaths every year are attributable to tobacco related diseases. In this case petitioner brought to the notice of the court the harmful effects of smoking on non-smokers due to passive smoking in public places. Supreme Court held that smoking is injurious to health of the smoker but there is no reason that health of passive smokers should also be injuriously affected, in any case there is no reason to compel non-smokers to be helpless victims of air pollution.
