Stone cancer | Effect of acid rain

Stone cancer is a cancer of buildings and it is not a small rather it is a huge or big issue of the environment and in this color of the buildings becomes yellow due to one fact and this fact is called acid rain. The main thing which is present in the air is the gas which is Sulphur dioxide and this gas affects badly to the buildings and surfaces who are painted and it causes yellowing. The best example of stone cancer is the Taj Mahal due to Sulphur dioxide its color becomes blackish.

What is its History?

Stone cancer, first of all, began in the European countries and after this, it started in North America after the great World war 2 and they increased in those areas of the county who increase their feeding of remnant energy. International teamwork statements that pollution of air and acid confession starts in 1972.

Then in 1974, another conference is done in Geneva and in this conference a good work is done which is that authority is formed which is for the reducing of the air pollution.

The development which was started in 1995 also marked up the starting of the more emission or estimation of Sulphur dioxide in the cities of the united states and as a result, almost there is a 88 percent estimation or decline of the Sulphur dioxide from 1990 to the end of 2017. 

Due to some strict work and meetings and strict actions which are explained already, there is a great decrease in the deposition of acid in both countries Europe and North America. 

And there are also some other records about the concentration of the hydrogen in the United States and the data which is collected and when it is measured it shows that there is a decrease in the concentration of the hydrogen in rainfall was forty percent from 1994 to 2008. 

 The concentration of deposition of acid in the other countries of the whole world is an increase there is an example of Asia this there is a great increase in the concentration of the Sulphur dioxide and the ammonium oxide and there is a good increase of only ammonia in the two countries one was China and other was India.

Effects of acid rain on headstones

The effects of acid rain are very bad because it destroys or ruin the shrines and sculptures by shedding the material and its other effect is that it completely corrodes the materials which form buildings or structure of these buildings. Builders always select granite glass ball and other things which is related to this and they use these materials as some strong materials so that these materials fight back against the harmful elements. But they completely surprise to see the reactions of chemicals between the acid rain and the materials of the buildings managed and they destroy over the time as its example is sugar is completely absorbed in the water.

What are the basics of acid rain?

To know the basics of the acid rain chemist’s degree or amount of this and determine what is the power of these corrosive and after measuring they said that the small numbers are they show the acrider. Here some of the results are given according to the scientists 

  1. If the pH of the water is equal to 7 then it is neutral.
  2. They said that in the areas in which industries are present their pH is run between 2 to 3.
  3. All these gases or molecules react with each other and they cause acid rain.

Abating of the buildings

One of the effects of acid rain on the buildings is that it completely damages the structures and erections because the acid rain is completely dissolving in the stone and it completely corrodes the steel or metal which is wide-open to the weather. 

In all of these materials, some of the materials have Caco3 which is completely dissolved by acid rain, and one thing in which there is no effect of acid rain is that which is sandstone.

Acid rain effects on the testimonials

 Builders always select granite glass ball and other things which is related to this and they use these materials as some strong materials so that these materials fight back against the harmful elements. But they completely surprise to see the reactions of chemicals between the acid rain and the materials of the buildings managed and they are destroying over time as its example is sugar is completely absorbing in the water.

The main thing which is present in the air is the gas which is Sulphur dioxide and this gas affects badly to the buildings and surfaces who are painted and it causes yellowing. The best example of stone cancer is the Taj Mahal due to Sulphur dioxide its color becomes blackish.

Impersonal statues

One thing which is said in this is the old buildings and the old statuettes and the stones of the tomb they are completely helpless to the acid rain due to one reason which is that they all are made up of limestone and when these statues are exposed to the acid rain their details can be lost or the beauty of the statue can be lost when the time is passed and slowly they are completely turn into a dull dash.

However, it is asked that there are some statues which are made up of metals they refrain the stones on the buildings from physical weakening but it can cause discoloration or it may cause the color of the stone lost.

Oxidized metals

Acid rain not only effects the metallic parts of the shrines buildings and passages when they are exposed to mist there are some other metals other than calcium which are completely dissolved in the stones of the building rather it also corrodes many other certain types of metals and these weak fewer metals are Cu and nickel and many other types of the steel.   

Slight steel and stainless steels are the weakest and all of the metals are corroded according to the researches because they use one of the most stronger and strongest.

What are the effects of acid rain?

The most common materials which are occurred and used for the buildings are stonework and marble and granite. The rain corrodes all of these materials to some extent and it’s destroying their original composition of the buildings. 

Acid rain damages the cement buildings which are present in some polluted countries like China and United States. After Cu, many other metals like zinc and bronze also react with the acid. The copper is completely dissolved from the bronze when it is washed down then it is oxidized and when they oxidize they are completely changed into green dyes.

Taj Mahal is affected by acid rain. It is a famous example of acid rain and its effects on the Taj Mahal.

In India, there a factory which is the main reason for acid rain and it completely change the color of the Taj Mahal and it turns its white color into yellow color.

  1. However, some of the arguments about this are that the yellow color is natural, or maybe the yellow color is due to the iron which is present in the marble.
  2. Some other native courts or residential have argued about this which is that the pollution of the air is the main reason for its color change and it destroys it completely.
  3. But the government of India has produced or gave a strong fact about this which is that all of you should control the emission and should help to protect the Taj Mahal.

Acid rain effect the aquatic lives:

Acid rain also affects and damages live in the water lakes and farms.

Acid rain is completely ditching in the soil and it causes very harmful effects on it which is that it completely washes the very important nutrients in the soil.

  • Acid rain also affects microorganisms.
  • Acid rain also affects decomposers.

Plants are more affected by acid rain which is that they become poisonous. When they are completely going to the roots of the plants than at that time plants become very weak.

Acid rain also affects the lives of aquatic animals and plants which are present in

the rivers lakes and in the seas because the acid rain when going the water then the fishes died and plants which are present in the rivers and the seas they become poisonous.

Effect of acid precipitation on the marble

When in the polluted air nitric acid and Sulphuric acid combine with the other calcite of the marble or shrines then the calcite is dissolved in it and when it is dissolved in it, as a result, they are exposed and the buildings look like very roughed and its material is completely removed and there is a complete loss of imprinted material. The surface of the stone in which material is present due to this is lost and only those spots are appearing which are very reactive.

Cement is also another thing that combines or reacts with the rain which is acid rain because cement is caco3 which is completely dissolved in the acid. Buildings which are made up of cement and work of art which are made up of cement also show the effects of the acid rain.   

In the old buildings and the old statuettes and the stones of the tomb, they are completely helpless to the acid rain due to one reason which is that they all are made up of limestone and when these statues are exposed to the acid rain their details can be lost or the beauty of the statue can be lost when the time is passed and slowly they are completely turn into a dull dash.

How Taj Mahal is affected by rain?

Taj Mahal is present in the city of India which is Agra. The air which is present at that place has a dangerous level of S and the oxides of the nitrogen and it has the biggest reason due to which Sulphur and oxides of the nitrogen is present here which is that in these areas there is a large number of the industries and power plants are present and they cover these areas. All these lead to acid rain and acid rain damaged or destroy the marble of the Taj Mahal and due to which its structure is completely changed which is so much attracted by many visitors all over the world.

Why the color of the Taj Mahal becomes yellow?

The color of the Taj Mahal turns yellow because of the air pollution which is present in the Agra where the Taj Mahal is present and on the other hand there is another reason for its yellowing color which is that coal is burning here.

Why the Taj Mahal is losing its color?

Taj Mahal is completely losing its color due to the feces of the insects and the air pollution which is present at that place.

Some of them said first of all its color turns into yellow and now it turns into brown and green color.
