The change of climate of the planet’s surface leads to the problem of greenhouse gases which “account for around 98% of the environmental pressure leading to climate change. They are: nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). The activity of these gases leas to the Global Warming Effect, as all three of them are able to trap heat in the atmosphere. The danger lies in the Earth’s rising temperature, which makes the glaciers melt. All the energy that turns out to being the atmosphere finds a way out through natural cataclysms such as storms and others.
Pollution disrupts our ecosystem and the balance in the ecosystem. With modernization as well as growth in our lives pollution has reached its top; resulting in the rise to global warming and other dangerous human illness. Pollution occurs in different forms; from air, water, soil, radioactive, noise, heat/ thermal and to light pollution. Every type of pollution has two sources of occurrence in nature; the point and the non-point
These harmful substances may increase the number of mortality or serious illness or may cause present or potential hazard to human health. Air pollution can further be classified into two which are visible air pollution and invisible air pollution. In another way, air pollution could be any substance that holds the potential to hinder the atmosphere or the well - being of the living beings surviving in it. The sustainment of all things living is due to a combination of gases that collectively form
Title: Environmental pollution and their effects on human Introduction Environment pollution is a worldwide problem and its potential to influence the health of human populations is great (Fereidoun et al, 2007; Progressive Insurance, 2005.). the way I understand it is the process of making land, water, air or other parts of the environment dirty and unsafe or to use. This can be done through the introduction of pollutant into a natural environment, but the pollutant doesn 't need to be noticeable. Pollution reaches its most serious proportions in the densely settled urban-industrial centers of the more developed countries (Kromm,1973).most of urban area perform more pollution by having more industries which release carbon dioxide which cause air pollution and also the vehicle contribute to air pollution. Environmental pollution is tangled with the unsustainable anthropogenic activities, resulting substantial public health problems.
With increase in industrialization and immense emission from vehicles due to huge transportation and much more, India is facing serious problems due to rising air pollution. Among all the pollutants released, SOx is one of the dangerous ingredients of polluted air. Apart from various health problems such as heart failure and breathing difficulties, Sox causes environmental hazards such as damage and destruction of water courses, vegetation, construction material and deterioration in soil quality. AQI is an indicator of air quality which depicts how polluted the breathing air is and forecasts how polluted it is to become. AQI helps government agencies to take preventive measures and steps to control the pollution level.
SYNTHESIS AND CHARACTERIZATION OF CERIUM OXIDE NANOCOMPOSITES AND THEIR CATALYTIC APPLICATIONS IN DIESEL SOOT ABATEMENT Introduction:- Air is the most essential constituent of environment for the sustenance of life on earth. In pure air, the proportion of different constituents like oxygen, nitrogen and other gases is fixed and definite. Overall health of our body and mind heavily depends upon the amount of pure, fresh air breathed. But, now a day’s pollution is the biggest threat to life. Major part of environment is getting polluted because of the mixing of particulate matter (PM), nitrogen oxides (NOX), & volatile organic compounds (VOC’s) produced by emission from diesel engines.
Further, emission from industrial plants, fuel combustion in motor vehicles, homes and buildings and thermal plants contains numerous chemicals that drift in the atmosphere causing air pollution. Once in the living food chain, the objectionable substances are accumulated beyond the permissible limits adversely affects the living beings. Some of the known effects on
Causes of Air pollution 1. Burning of Fossil Fuels: Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles is one the major cause of air pollution. Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause immense amount of pollution. We rely on them to fulfill our daily basic needs of transportation. But, there overuse is killing our environment as dangerous gases are polluting the environment.
Air Pollution is a condition in which the quality of the air is degraded due to presence of harmful substances particulate matter, and biologically agents. Certain gases, particles and other unwanted substances have a damaging effect on the environment and humans. These particles are called, pollutants. A pollutant can have
Destroying the world to survive: POLLUTION Background The presence and use of substances that are harmful and poisonous to the environment, especially being contained in the water, air and soil are factors that contribute to destroying the environment. Pollution continues to be an important public health concern in our societies. Since the development of Industries within the societies our environment and health conditions have been endangered by the high levels of pollution. The sudden increase in population has led to many informal and unhealthy polluted settlements. Though there are types of pollutions, it has come to my senses that the societies that we live in today are in danger of facing all kinds of pollutions because we human beings contribute to the environment
