Acid rain - it's measurement and prevention

Acid rain is a result of air pollution. When any type of fuel is burnt, lots of different chemicals are produced. The smoke that comes from a fire or the fumes that come out of a car exhaust don't just contain the sooty grey particles that you can see - they also contains lots of invisible gases that can be even more harmful to our environment.Power stations, factories and cars all burn fuels and therefore they all produce polluting gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain".

Measurement of acid rain - 

Acid Rain
Acidity and alkalinity are measured using a pH scale for which 7.0 is neutral. The lower a substance's pH (less than 7), the more acidic it is; the higher a substance's pH (greater than 7), the more alkaline it is. Normal rain has a pH of about 5.6; it is slightly acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid.  Acid rain usually has a pH between 4.2 and 4.4.

Effects of Acid Rain -

  • Soil pollution
  • Damage to forests
  • Effect on human health
  • Effect on materials
  • Visibility impairment 
  • Effect on paint coatings

How to prevent acid rain - 

  • Use energy efficiently
  • Reuse the materials 
  • Travel by bus or train for long distances
  • Travel by cycle or by walking for small distances
  • Use high quality fuels that creates less pollution.

What is Green Building ?

Green Building 

A ‘green’ building is a building that, in its design, construction or operation, reduces or eliminates negative impacts, and can create positive impacts, on our climate and natural environment. Green buildings preserve precious natural resources and improve our quality of life.

Any building can be a green building, whether it’s a home, an office, a school, a hospital, a community centre, or any other type of structure, provided it includes features listed below.

  • Efficient use of energy, water and other resources
  • Use of renewable energy, such as solar energy
  • Pollution and waste reduction measures, and the enabling of re-use and recycling
  • Good indoor environmental air quality
  • Use of materials that are non-toxic, ethical and sustainable
  • Consideration of the environment in design, construction and operation
  • Consideration of the quality of life of occupants in design, construction and operation
  • A design that enables adaptation to a changing environment

Rainwater harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways.
With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help to tackle these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones.

This method of conservation of water can be used in homes , parks etc. Farmers can use rainwater harvesting for
  • To recharge their dry borewell
  • To improve water supply
  • To increase food production
  • To increase life of water resources

Concept of Global warming, causes and prevention

Click here to Download Pdf 
Global warming is a phenomenon of climate change characterized by a general increase in average temperatures of the Earth, which modifies the weather balances and ecosystems for a long time.
 It is directly linked to the increase of greenhouse gases in our atmosphere.

In fact, the average temperature of the planet has increased by 0.8ยบ Celsius (33.4° Fahrenheit) compared to the end of the 19th century. Each of the last three decades has been warmer than all previous decades since the beginning of the statistical surveys in 1850.
At the pace of current CO2 emissions, scientists expect an increase of between 1.5° and 5.3°C (34.7° to 41.5°F) in average temperature by 2100. If no action is taken, it would have harmful consequences to humanity and the biosphere.

Global warming causes 

The massive use of fossil fuels is obviously the first source of global warming, as burning coal, oil and gas produce carbon dioxide - the most important greenhouse gas in the atmosphere - as well as nitrous oxide.

The exploitation of forests has a major role in climate change. Trees help regulate the climate by absorbing CO2 from the atmosphere. When they are cut down, this positive effect is lost and the carbon stored in the trees is released into the atmosphere.

Waste management methods like landfills and incineration emit greenhouse and toxic gases - including methane - that are released into the atmosphere, soil and waterways, contributing to the increase of the greenhouse effect.

Another cause of global warming is intensive farming, not only with the ever-increasing livestock, but also with plant protection products and fertilizers. In fact, cattle and sheep produce large amounts of methane when digesting their food, while fertilizers produce nitrous oxide emissions.

Modern life is highly dependent on the mining and metallurgical industry. Metals and minerals are the raw materials used in the construction, transportation and manufacturing of goods. From extraction to delivery, this market accounts for 5% of all greenhouse gas emissions.

Finally, overconsumption also plays a major role in climate change. In fact, it is responsible for the overexploitation of natural resources and emissions from international freight transport, which both contributes to global warming.

How to control global warming

  • Use renewable sources of energy
  • Plant more and more trees
  • Use HFC instead of CFC
  • Reduce forest degradation
  • Use energy more efficiently
