Air Pullution


CAUSE AIR POLLUTION

    Power Lines



Some power lines are not insulated and are high voltage. This creates air pollution.

    Mills and Plant





Mills and plants, include paper mills, chemical plants, iron mills, steel mills, cement plants and asphalt plants, release emissions into the air causing air pollution.

     Indoor Air Pollution





Sick building syndrome (SBS) is the term used when there is indoor air pollution. This happens when there is not enough ventilation to disburse the toxic fumes from new carpet, paint and/or cleaning chemicals that are used indoors. Mold can also cause SBS.






Air pollution is caused by a wide variety of things. The earth is great at cleaning the air on its own. However, air pollution has grown so much, the earth can no longer clean all of it. This is starting to have adverse effects on the environment such as causing acid rain, smog and a wide variety of health problems.






Factories, office buildings, homes and power-generating stations burn fossil fuels, which cause air pollution. The burning of oil and coal (fossil fuels) also contributes to smog. This air pollution destroys plants, damages buildings and creates oxidation on iron.

       Fertilizer Dust





Dust from fertilizers used to help plants grow causes air pollution.

     Mining Operations





Mining causes air pollution by releasing a variety of particles.

     Combustion Engine Exhaust





Cars, trucks, jet airplanes and other combustion engine vehicles cause air pollution. The exhaust from these contains carbon monoxide, nitrous oxide and gaseous oxide. This type of air pollution creates smog (as seen in Los Angeles) which causes respiratory health problems and holes in the ozone layer, which increases the exposure to the sun's harmful rays.

     Radioactive Fallout





Radioactive fallout causes air pollution from the nuclear energy dispersed, which is a dust.



     Pesticides



Pesticides used to kill indoor and outdoor pests, insecticides used to kill insects and herbicides use to kill weeds all cause air pollution.

      Petroleum





Petroleum refineries release hydrocarbons and various particulates that pollute the air.

CONTAMINANT OF AIR POLLUTION


PRIMARY

Primary air pollutants are the ones that are emitted directly into the atmosphere by the sources . such as power-generating plants


SECONDARY
Secondary air pollutants are the ones that are formed as a result of reactions between primary pollutants and other elements in the atmosphere. such as ozone.


Solver Air Polution

     Avoid Second-Hand Smoke – Passive smoke is produced by smokers but can harm non-smokers as well.  Try to avoid areas that are filled with smoke and ask smokers to smoke outdoors.

     Check For Radon – Radon arises naturally from the ground and could cause fatal lung cancer.  Purchase a testing kit to find out if the radon level in your home is dangerously high.

     Don't Smoke – When you smoke, you not only harm yourself but also create problems for other people's health.

     Don't Use Wood Stoves – Wood stoves emit large amounts of CO indoors.  This can build up in your home and create a dangerous health risk.

    Drive Less – Cars are one of the largest sources of air pollution.  You should carpool or take public transportation whenever possible.

    Have Plants – Plants can absorb some dangerous chemicals that are polluting your air.  In doing so, they reduce your risk of getting sick.

    Look For Asbestos – Many old homes still contain asbestos from when they were built.  Asbestos can get into your lungs, stomach, and chest, causing problems that can prove fatal.  As a result, you should look around your home for asbestos that is crumbling or loose and remove it.

     Minimize Air Conditioning – If you can avoid air-conditioning, do so.  By keeping windows and shades shut, you may be able to avoid needing air conditioning, which will mean using less energy.

     Use Efficient Appliances – To cut down on energy usage, buy energy-efficient home appliances.  Less energy usage will not only decrease pollution, it will decrease your energy bill too.

    Watch Out For Formaldehyde – Don't buy products containing formaldehyde because it can enter the air and cause chronic respiratory problems.

                                                 thank you , maybe useful :D
