Outdoor sources are like gasoline vapors at gasoline service stations, motor vehicle exhaust, emissions from industrial sources utilizing benzene and toluene, etc. Both benzene and toluene are harmful for human health as they cause damage to central nervous system, dysfunction, narcosis, tremors and death. Benzene and toluene are also carcinogenic in nature. Biofilters have been used for removing hazardous substances such as toluene, chlorinated hydrocarbons, and the mixtures of benzene, toluene, ethylbenzene, and xylenes (BTEX) from gas streams (Leson and Winer 1991). In biofiltration polluted air containing odorous gases is passed through a porous media that may be wood chips, soil or compost or mixture of above that support microorganisms.
Air pollution is destroying the environment and the human health. Pollution is when a new substance is introduced to the environment and has negative effects on it. Pollution is found in different forms which include: air, soil, water, radioactive, noise, heat/thermal and light. Air pollution is many times produced by the excessive burning of fuels such as cooking, driving and other industrial activities, which produce chemicals and other substances that pollute the air. Sulphur dioxide that makes air toxic is produced by the burning of coal in everyday normal activities that make the smoke produced by factories, cars and of burning wood.
Pollution released into the air damages the ozone layer in Earth’s atmosphere. Due to the chemicals in the air there is widespread concern that the ozone layer is deteriorating due to the release of pollution containing the chemicals chlorine and bromine. Such deterioration allows large amounts of ultraviolet B rays to reach Earth, which can cause skin cancer and cataracts in humans and harm animals as well. Researchers also have documented changes in the reproductive rates of young fish, shrimp, and crabs as well as frogs and salamanders exposed to excess ultraviolet
Life on earth has been susceptible to many natural and man-made disasters which have ultimately affected the growth and development of animals on earth. Pollution deprives the earth of its natural resources such as, land, water, and air, all of which are essential to the well being of living organisms. Distinctly, pollution has a negative influence on air required for the survival of most creatures. Structures and inventions constructed by man, such as factories and cars, contribute to an increased concentration of harmful substances in the air. The burning of fossil fuels allows for toxic levels of smoke emissions to filter into the atmosphere.
Like ride a motor bike, use air conditioner, industry rubbish, etc. Furthermore, air pollution can cause the global warming and green house effects in long day it’ll cause skin cancer and other kinds of cancer. Or at least abuse thermal energy too much.

Like: Water pollution, thermal pollution, etc.
In addition to the soil, humans and animals living around these landfill sites are greatly harmed. Household waste, industrial waste etc. contain residues of harmful toxic inorganic and organic chemicals. In these residues, radiation elements such as strontium, cadmium, uranium, ladders are found, which affect the vitality and fertility of the land. Fly ash is a major source of pollution surrounding the industrial area.
As an instance, dust fires, Wild land, volcanic activity and storms are sources that emit gases and particulate matter into the atmosphere, according to  “In most of the areas wind can naturally form dust storms. When this activity occurs, a particulate matter is added to the air so it can have a natural warming effect that also can be a health hazard for living creatures”. In spite of this,
In the first place, air pollution could affect the environment notably. Because of the sulfur acid which is produced by human activities, the clouds would gain the acidic material than with the rain fall into the ground. This could adversely affect the nutrients in the soil and pollute the water. Moreover, the rain might damage the buildings or cause disease to human (Eschooltoday, n.d). The other environment problem caused by air pollution is global warming.
Emissions from natural gas combustion and raw cement burning can cause negative effects on public health and lead to degradation of the surrounding environment. b. Several health problems such as respiratory disorders and allergies are attributed to such emissions. Inhalation of NOx interferes with the function of the human respiratory system and worsens the health condition of asthma patients even at low concentrations c. Increased SOx levels in the atmosphere are blamed for degradation of agricultural productivity and death of some plants in early stages. Similar impacts on human health and agricultural productivity are linked to high level of cement dust in the atmosphere.
The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease of the percentage of these gases can be harmful for our survival. This is why it is extremely important to take care
