Air is the most important and vital nutrient for plant and animal life. It is the gift of Mother Nature to our planet, so that we lead a healthy life. In the absence of air, there would have been no life on this planet. The Earth is surrounded by an envelope of air called Atmosphere that protects the life on Earth.
Air is the name given to the Atmosphere and is a layer
of several gases. The most important use of air is that animals use it for
breathing and plants use it for photosynthesis in addition to breathing. Air is
a mixture of several gases. Oxygen gas present in the air is used for
breathing. About 1/5 th of air is oxygen, which is our life force.
All animals are
designed to run on oxygen. Human beings can not live without oxygen. Our body is made up of several millions of
cells. When we breathe in air, oxygen is absorbed by the lungs get mixed in the blood stream and is distributed to all the cells of our body. In order to remain healthy, our
cells should get enough oxygen. Therefore, a steady supply of fresh air is
essential. Fresh air provides a steady
supply of oxygen which is needed by every tiny cell of our body.
We tend to stay
indoor for most of the time. We end up breathing the same air again and again. The percentage of oxygen
in the indoor air goes down and we will be breathing stale air. Our body
accumulates gaseous wastes, we become
weak and our body will not function efficiently. If this situation continues we tend to
acquire several diseases that are difficult to cure. Hence it is very necessary
to prevent and control indoor air pollution.
Indoor Air
pollution is a matter of great concern to mankind. We have failed to monitor the
indoor air pollution. We have also failed in developing suitable technology to
monitor indoor air quality. Indoor air quality
signifies the health and the well being
of humanity. Our life has progressed with the advancement
of technology. Quality of human life, wellness and well being depends on
the purity of the air that we breathe.
Indoor air
pollution is one of the top most problems of our environment. It contributes to out door air pollution and
increases green house gases. It is also responsible for Global Warming and Climate Change in addition
to creating health problems. So, it is
necessary that we monitor and breathe fresh indoor air. Not only the indoor air
should be free from dust and mites but also we should adopt certain
important Green Measures to control
and prevent indoor air pollution. Following are certain simple measures to
prevent Indoor air pollution.
- Keep the windows open to let fresh air into the house.
- If bad odour is troubling, boil scented herbs like neem, tulsi, scented flowers and keep them in a fancy bowl.
- Hang a packet of Zeolite, a natural mineral in rooms where bad odour is more. Zeolite is a natural mineral that absorbs bad odour.
- Mop the floor and keep it dry. Having a door mat at the entrance of the house will prevent dust entering into the house. It is essential to remove the dirt and dust from the door mat.
- Use an exhaust fan or open the window while cooking.
- Use fragrance free, naturally scented laundry products.
- Use mild cleaners which do not have any artificial odour.
- Avoid using aerosol sprays, carpet cleaners,furniture polish, air freshners etc.
- Use a sliced lemon and baking soda to clean kitchen odour.
- Make home free from cigarette smoke.
- Buy electronic items that are ecofriendly. Do not use old ones as they consume more energy and should be replaced.
- CFL and LED lighting fixtures should be used. They are expensive, but they are energy efficient and durable.
- Repaint walls with with low VOC paints and use non-toxic natural cleaning agents.
- Rooms with AC should have no leakges, ,false ceilings, carpeted floors, energy efficient windows for best cooling.
- Use wooden furniture.
All these steps
taken are simple and can control or prevent indoor air pollution to a certain
extent only. We have to think of certain
innovative methods to improve the indoor air quality in our homes.
Use of Bio filters to control Indoor Air
Pollution:
Bio filtration is a pollution
control technique using living
materials to capture and biologically degrade and process pollutants. Biofilters
use microorganisms to remove indoor air pollution. Bio filters reduce air
pollutants by the principle of Hydrophonics and Phytoremedation. Pollutants are
absorbed by plants through the root system to improve indoor air quality.
How
does it work?
Air
is drawn through wet biomass. Contaminants and pollutants move from air to
water and are broken down. Green plants improve the effectiveness and reduce
the need for fresh air as contaminated air is purified. Thus,there is constant
circulation of pure air in the room.
The benefits of
Bio filters:
- Improved air quality with no energy consumption.
- Safe technology and an aesthetic appeal.
- Airborne spores are not generated.
- No hazardous waste is generated in this system.
- Easy to install and is cost effective
In
this process naturally occurring
moicrobes are utilised to absorb and digest pollutants from indoor air,
converting them into carbon-di-oxide, mineral salts and water. Microbes used in
bio-oxidation digest the pollutants in various steps.The pollutants pass
through bacterial cell wall. The enzymes present in the bacteria transform the
pollutant molecules by pulling them apart until they are converted into
different compounds. For example, when phenolic
molecules have to be digested, Carbon & Oxygen combine to form CO2
gas and Hydrogen & Oxygen combine to form H2O.Also in this process not only
oxygen combines to form oxides but also provide energy needed by the cells for
the reaction.
Bio-oxidation
method is nodoubt a good method to contain indoor air pollution. But lot of
research has to be done on the technology of putting it into practice. If a
proper technology is promoted with the help of microbes then air gets purified
and the effects of global warming can also be reduced.
Construction of
Green Homes:
Green
Homes are houses designed
keeping in mind the elements of nature & making full use of natural
resources that do not pollute, or harm the environment. The basic elements of Green Homes are solar
water heating systems, use of glass panels to allow light during the day, rain
water harvesting, waste minimisation,maximising energy use,water conservation
& use of energy efficient equipments.
Building Green Homes will have the following features:
- Buildings are built using hollow blocks and naturally available materials from the environment.
- Light colours are used for exteriors of the structures to reflect sunlight back into the atmosphere to prevent radiation of heat.
- Shade trees should be planted in the west and south direction of the building.
- Roof garden, wall garden and sloping roofs are constructed to reduce heat.
- Rain water is suitably harvested during rainy season and is utilised.
- Solar power panels, Bio-gas plants and Wind turbines are installed to generate energy.
- Grey water treatment plants are set up to recycle waste water. This helps in reducing water bill and to conserve water.
- Bio-degradable waste generated by the residents are utilized to produce eco-friendly manure for kitchen/roof/wall gardens.
- Energy efficient lighting systems are made use of to reduce the cost and consumption of electricity.
- Water and power consumption of such buildings is minimised.
- Waste water generated is properly recycled and this eliminates water pollution.
- Maintenance of the building is less expensive and is easy.
- Life of the Green Building is longer.
