This can be attributed to increasing vehicular density which ultimately results to higher vehicular emissions and so does the pollution. Also, the role of meteorological conditions in dispersion of pollutants is also discussed with the help of trend analysis technique. INTRODUCTION The World Health Organization estimates that air pollution contributes to approximately 800,000 deaths and 4.6 million lose their life years annually . Developing nations are particularly affected by air pollution; as many as two thirds of the deaths and lost life years associated with air pollution on a global scale occur in Asia . The data available from the Environment information system (ENVIS) centre indicates that the levels of small particles less than 10 micron (PM10) are showing sharp rising trends in the Indian cities.
“The air quality in India is so bad that it will hurt your head.”-The New York Times. (GETTLEMANNOV, 2017) The 2017 State of Global Air report, published by the Health Effects Institute, shows that air pollution-related deaths in Indian between 1990 and 2015 rose by almost 150%. More simply, today in India 14.7 people in every 100,000 die of an o-zone related illness. (Jones, 2017) LOST OF BIODIVERSITY The main cause of loss of biodiversity are deforestation, global warming, overpopulation and pollution are few of the major causes for loss of biodiversity. In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly.
Reduce the speed of the farmer that they inject the water. Due to the hot weather the farmer need to get the water resources to cultivate the plants. The farmers in order to survive to dwindle the groundwater. The second cause is the water pollution. With the development of the city in India, the environment has become the worst destroyed, the city will produce the dirty water and pollute the fresh water and the city has no money to support the whole water system, so the dirty water cannot be cleaned clearly and give the hurt to the whole environment.
Delhi made headlines in 2017 when it was ranked by World Health Organisation (WHO) as the 11th most polluted metropolis in the world. The capital city is blanked by a lethal smog, endangering the lives of 28 million inhabitants. The Air Quality Index indicated that Delhi has reached alarming level of PM 2.5 concentration of air pollutants per cubic metre (Smith,2017). The Indian Medical Association proclaimed a public health emergency describing the metropolis as a “gas chamber” (Mole,2017). Environmentalists found that harmful exhaust fumes from vehicles, poisonous smoke produced by coal- based power plants and dust from construction sites and road works have deteriorated the quality of air.
The exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain. There are also some natural causes which cause acid rain to happen. The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes. Thus, for example, fumaroles from the Laguna Caliente crater of Poás Volcano create extremely high amounts of acid rain and fog, with acidity as high as a pH of 2, clearing an area of any vegetation and frequently causing irritation to the eyes and lungs of inhabitants in nearby settlements.
France-3 Minister for Energy Introduction The pollution of the air is a major challenge that has a negative impact on everyone. There are various types of pollutants. Besides, the many ways to group pollutants, for instance, pollutants can be classified according to the distance in which their adverse effects are felt. Basing on this classification, there are pollutants that affect the global and local ecology. Some of the pollutants that affect local ecology include; emission of carbon (II) dioxide from cars, cigarette smoke.
For example, technology improves the environment in terms of the intense and sophisticated methods of agriculture, enables us to construct better quality houses that can withstand earthquakes and tsunami. Nevertheless, sometimes excessive land exploitation due to the effectiveness of new equipment can diminish the soil’s fertility. Cars, factories, and power plants also pollute the air by emitting huge amounts of carbon dioxide (CO2), which can, eventually, initiate and trigger an ozone hole on the stratosphere of the Mother earth later. Additionally, usage of fuels can also contaminate the air. For example, burning any kind of fossil fuel releases toxic gases such as sulfur dioxide (SO2), nitrogen dioxide (NO2) and carbon dioxide (CO2) in the air.
The pollution also harms animals and humans. Since 2010, the number of cases of chest and throat diseases in India has been raised by 30 %. This is equivalent to approximately 3, 5 million persons. We are by other means talking about a vast amount of people. If we compare these numbers with our own country, Norway, 3, 5 million people are equivalent to 7 out of every 10 Norwegians!

Caries oil, runoff from streets heavy metals, rubber, and other containments from automobiles. Poorly treated or untreated sewage can be low in dissolved oxygen and high in pollutants such as chemicals and bacteria.
Air pollution continues to threaten the climate worldwide. Invisible particulate matters in the air are chemical, physical or biological agents that modifies the natural characteristics of the at-mosphere and contaminate the indoor or outdoor environment. Power plants, household combustion devices, automobiles and industrial production are common sources of air pollu-tion. The natural sources also exist and they include forest fires or volcanic eruption. Accord-ing to a World Health Organisation (WHO) assessment of the burden of disease due to air pollution, more than 2 million premature deaths each year can be attributed to the effects of urban outdoor air pollution.
