    POLLUTION OF GANGA RIVER

    The main causes of water pollution in the Ganges river are the increase in the population density, various human activities such as bathing, washing clothes, bathing of animals, and dumping of various harmful industrial waste into the rivers.

    POLLUTION OF YAMUNA RIVER

    The most polluted river the Yamuna. ... Despite such an esteem status, rivers are being polluted due to open sewage drains, lack of sufficient sewage treatment plants, soil erosion, and by dumping plastic garbage in river water, etc.

    EFFECT OF AIR POLLUTION ON TAJ MAHAL

    Taj Mahal is slowly decaying due to air pollution. Dense smog created by human activities is slowly discoloring the marble and turning it to sickly yellowish-brown color.

    Now the question arises who is to be blamed. There are several factors: heavy traffic, wood-burning crematoriums, smoke from neighbouring factories, and Agra’s growing population, the last of which demands more and more water. As the Yamuna River dries up, it risks sliding the Taj Mahal off its picturesque banks into a sea of mud.

    The burning of Municipal Solid Waste in the open results in thick toxic smog which is the main reason for the discoloration of the Taj Mahal. These wastes should be properly deposited in landfalls that do not happen and the reason is bureaucratic incompetence.

    The Supreme Court of India has ordered that all the wood-burning crematoriums be replaced by an electric one. The UP Govt has banned the burning of cow dung which serves as a cheap source of fuel but at the same time, it produces brown carbon the same type which is turning the Taj Mahal into yellowish-brown color.

    It is also the responsibility of every citizen of Agra, Delhi and its neighbouring states to see that activities that lead to producing of toxic smog should be stopped.

    We need a bold and effective solution ASAP if we want our future generation to see the beautiful Taj Mahal in its former glory.

    Yamuna pollution main reason behind Taj Mahal decay: study

    India's environmental science and conservation news

    Polluted Yamuna, not industrial emission, main reason behind Taj Mahal decay: study

    by Snigdhendu Bhattacharya on 25 November 2021

    Yamuna pollution was identified as a threat to the Taj five years ago, blaming the formation of phosphorous in the river water for the breeding of insects whose excreta was leaving patches on the marbles.

    Now, a new study offers a different perspective, identifying hydrogen sulphide emitted from the polluted Yamuna as more corrosive than sulphur dioxide that comes from industrial pollution that has been largely blamed for the decay in the Taj’s marble.

    While this study to identify the principal corrosion agent was conducted on exposed metals in Taj premises over four years, the authors recommended similar experimentation on marbles for a 10-year-period for a definitive understanding.

    Over the years, visitors to the Taj Mahal have been complaining of foul smell that’s ruining their experiences at the majestic 17th-century Mughal architecture listed as one of the New Seven Wonders of the World. The gas responsible for the odour may in fact be doing greater harm – it is likely the culprit behind the discolouration of the Taj’s glorious white marbles.

    The stink coming from the black waters of the Yamuna river that flows prompted a group of scientists to explore if the gas that was responsible for the odour – hydrogen sulphide (H2S) – also had corrosive effects. They found that H2S released from polluted Yamuna water had a more corrosive impact than sulphur dioxide (SO2) released by industrial pollution in Agra city.

    The findings assume significance, as initiatives around protecting the Taj from being affected by pollution have largely been concerned with tackling industrial and vehicular pollution, while Yamuna pollution has not got as much attention until five years ago.

    For over three decades now, sulphur dioxide has been considered to be the main pollutant behind the decay in the glorious white marbles. Yamuna pollution was also blamed for the impact on the marble structure, in a 2016 report of the Archaeological Survey of India submitted before the Supreme Court of India, but from a different perspective – it highlighted the growth of the insect of the genus Goeldichironomus, in stagnant Yamuna water devoid of aquatic life and blamed the insect excreta for the green and brownish patches on the Taj marbles.

    The recent study, however, indicates that the polluted Yamuna might be harming the Taj in more than one ways.

    “We tried corrosion deformation studies using various air pollutants like SO2, NO2 (nitrogen dioxide), NH3 (ammonia), CO (Carbon monoxide), CO2 (carbon dioxide) and H2S. Most interestingly, H2S was found to be the most problematic among all. Our preliminary investigation establishes that river Yamuna, which carries untreated wastewater of the entire Agra, was responsible for the generation of H2S,” Dipankar Saha, a former additional director of the Central Pollution Control Board (CPCB) and one of the co-authors of the paper, told Mongabay-India.

    “H2S gas is acidic and corrosive therefore much attention is needed to clean river Yamuna,” added Saha, who had also served as head of the CPCB’s air laboratory for 12 years.

    Published recently in the International Journal of Environmental Science and Technology, the study also noted, “The wind rose diagram developed during the period of the study suggests that the direction of the wind opposed the industrial pollutants moving towards the monument” and that “hydrogen sulphide emitted from the polluted Yamuna River… has a dominant role.”

    The study titled Role of air pollutant for deterioration of Taj Mahal by identifying corrosion products on the surface of metals, is co-written by four others, apart from Saha – Achal Pandya, head of the conservation unit at Indira Gandhi National Center for Arts, New Delhi; and Jitendra Kumar Singh, Sharma Paswan and DDN Singh from the Corrosion and Surface Engineering Division of the National Metallurgical Laboratory, Jamshedpur.

    Pandya told Mongabay-India that it was necessary, for the protection of the Taj from discolouration, that the Yamuna is cleaned and the city’s sewage is allowed into the river only after treatment. “It’s no longer a river, its water is unusable. But we should remember that the Yamuna included the original Taj Mahal landscape. The river was very much part of the planning of the entire premises.”

    The corrosion deformation study was conducted on metals – samples of carbon steel, zinc and copper left exposed at the Taj Mahal premises – and the report concluded that “all evidence suggests that hydrogen sulphide emitted from the polluted Yamuna river flowing very close to the exposure site (the premise of Taj Mahal) has a dominant role on the corrosion rate of metals.”

    “The finding of this study leads to the conclusion that the fading of white marbles of the Taj Mahal may be due to the corrosive effect of hydrogen sulphide emitted from the polluted Yamuna River,” the report said.

    Answer:

    One of the main environmental problems in India is water pollution. Water pollution leads to contamination of water sources such as rivers, oceans, lakes, groundwater, etc. Because of water contamination, the Ganga and Yamuna are polluted.

    The visitors who go and people who live there because of them Ganga and Yamuna are mainly contaminated.

    The visitors who visit there and take shower, contaminate the water by dumping the waste stuff in the water and contaminates it.

    People wash dirty clothes and factory outlet are reaches the river which pollutes the water.

    The polluted air around them is created by the factories near the Taj mahal. Taj mahal is affected by emissions from the air. The government ordered certain factories nearby Taj mahal to stop or track the sound and polluted fumes that emerges from the vehicles, making the colorless and unshaded Taj mahal marble, so the use of CNG petroleum was ordered by the government.
