Idol Immersion: Aquatic Pollution And Toxicity Crisis

Idol immersion is an important aspect of Hindu culture, marking the farewell of deities to their abodes. However, this practice has come under scrutiny in recent years due to its adverse environmental impact, particularly the pollution of water bodies. The idols are often made with toxic materials and decorated with harmful paints, leading to increased heavy metal concentrations and toxic levels in the water, damaging the ecosystem and posing risks to human health. With growing awareness, efforts are being made to mitigate the pollution caused by idol immersion, including the creation of artificial ponds and the promotion of natural dyes.

Heavy metals in paints used to colour idols

Idol immersion during Hindu festivals leads to water pollution, adversely affecting the aquatic ecosystem and human health. The idols are usually made of Plaster of Paris, plastic, and cement, and are decorated with toxic paints and heavy decorations. These paints are highly pigmented and consist of heavy metals such as white lead, lithopone, chrome yellow, cadmium sulphide, barium chromate, vermillion, red lead, and mercury.

The heavy metals in these paints have severe toxic effects on aquatic life, causing fish deaths and plant destruction by blocking the natural flow of water. They also add an acidic level to the water, which is highly dangerous for the environment and marine life. These metals can cause waterborne and skin diseases in humans when they come in contact with the water, and can also accumulate in the food chain when absorbed by fish.

Historically, idols were made from clay and treated with turmeric and other herbal products to avoid polluting water bodies. Eco-friendly paints for clay idols are now being developed from natural resources to protect the environment from pollution. These paints are made from natural colours and pigments found in vegetables, fruits, and minerals, and are easily dissolvable without harming the environment.

To reduce water pollution, idol makers are encouraged to revert to using clay idols decorated with natural dyes and treated with natural products. Additionally, the use of special artificial ponds for idol immersion can help contain pollutants and heavy metals, preventing them from entering larger water bodies.

The adverse effects on aquatic life and the ecosystem

Idol immersion has been found to cause heavy metal contamination in water bodies, which adversely affects aquatic life and the ecosystem. The idols are often decorated with toxic paints containing heavy metals such as lead, mercury, cadmium, arsenic, zinc, and chromium. These metals, when mixed with water, add an acidic level to the water, which is highly dangerous for the environment and marine life. They can cause waterborne and skin diseases in humans when they come in contact with the water. The high nitrate and phosphate levels in the water lead to eutrophication, and the post-immersion period has also noted a rise in biochemical oxygen demands, oil, and grease levels, which pose a serious threat to human and aquatic life.

The idols themselves are usually made with materials such as plaster of Paris, plastic, cement, clay, cloths, iron rods, and bamboo, which can further contribute to water pollution when immersed. The colourful and shiny idols are often the most harmful, as they have been treated with more toxic elements during their creation. In addition to the idols, heavy elements such as metal jewellery and flowers are also immersed, adding to the pollution in water bodies. The flower waste, in particular, is often cultivated with fertilizers and pesticides, which can leave a residue that affects the fragile ecosystem.

The immersion of idols has been found to cause significant alterations in water quality, with heavy metal pollution damaging the ecosystem by killing fish, destroying plants, and blocking the natural flow of water. This pollution also affects the fertility of the nearby land and pollutes drinking water sources. The practice of idol immersion has been noted to have a particularly detrimental effect on various parts of India, including the Bhoj wetland, Budhabalanga River, River Ganges, Hussainsagar Lake, and Chhatri Lake, among others.

To mitigate the adverse effects of idol immersion on aquatic life and the ecosystem, several solutions have been proposed. One suggestion is to designate special artificial ponds or pits for idol immersion, preventing the pollution of larger water bodies. Another solution is to encourage idol makers to revert to traditional methods, using clay and natural dyes obtained from flowers, leaves, roots, wood, and seeds to create idols, thus reducing the toxic chemicals used in the idol-making process. Strict policy-making, effective awareness campaigns, and legal enforcement have also been recommended to control and reduce pollution from idol immersion gradually.

The rise in nitrate and phosphate levels in water bodies

Idol immersion is a common practice in Hindu culture, where clay idols of deities are immersed in water to mark the end of worship. While this practice is an important aspect of their culture, it has also become a significant contributor to water pollution in India and other parts of the world. The rise in nitrate and phosphate levels in water bodies, along with an increase in heavy metal concentration, has been observed after idol immersion activities, leading to eutrophication and adverse effects on aquatic life and the entire ecosystem.

The idols themselves are often made of materials like plaster of Paris, plastic, cement, clay, cloths, iron rods, and bamboo. The use of toxic paints and decorations further adds to the problem. These paints contain heavy metals such as mercury, cadmium, arsenic, zinc, chromium, and lead, which leach into the water when the idols are immersed. The colourful and shiny idols, in particular, are an indication of the presence of these harmful and toxic elements.

The water bodies, especially rivers like Hooghly in Kolkata, India, have shown a significant increase in heavy metal concentration after idol immersion. Studies have revealed that the idols and their decorations contribute to the high levels of toxicity in the water. The paints used on the idols contain metals such as lead, chromium, and mercury, which are released into the water during immersion. These metals not only affect aquatic life but also pose a serious threat to human health if the polluted water is consumed or used for other domestic purposes.

To address this issue, some suggestions have been made, such as creating special artificial ponds or pits for idol immersion, as implemented by several State Pollution Control Boards. This helps contain the pollution and restrict heavy metals from entering larger water bodies. Another suggestion is to encourage idol makers to revert to the traditional use of clay and natural dyes or herbal treatments, such as turmeric, to reduce the toxic chemicals released during immersion. While idol immersion is an important cultural practice, it is essential to find a balance between religious rituals and environmental conservation to minimise the rise in nitrate and phosphate levels in water bodies caused by this practice.

The use of clay idols and natural dyes to reduce pollution

Idol immersion during Hindu festivals leads to heavy metal contamination and water pollution, adversely affecting aquatic life and the entire ecosystem. The idols are usually made from non-biodegradable materials like Plaster of Paris (POP), plastic, cement, and toxic paints containing heavy metals like lead, mercury, and chromium. These metals mix with the water, increasing its acidity and endangering the environment, marine life, and human health.

To reduce pollution, people can switch from toxic paints to natural dyes and opt for clay idols instead of POP, plastic, or cement ones. Clay idols are biodegradable and do not contain harmful chemicals or metals, making them a more environmentally friendly option. They are also cost-effective and can be decorated according to one's preferences. Using natural dyes obtained from flowers, leaves, roots, wood, and seeds can further reduce pollution levels. These dyes have antibacterial properties and enhance the breathability and softness of fabrics. They also contribute to sustainability by minimizing water usage and reducing the carbon footprint of the textile industry.

Some brands, like Suninow and B S NATURALS, offer eco-friendly clay idols that are 100% biodegradable and soluble in water. These idols are made from natural pot clay (kachi mitti) and packaged carefully for safe delivery. Additionally, Swadeshi Blessing's Clay Ganesha Idols are handmade and hand-painted by local artisans, promoting the rich heritage of the country.

To minimize water pollution, people can also immerse idols in special artificial ponds or temporary water tanks built by authorities instead of common water sources. This restricts pollutants and heavy metals from entering larger water bodies and can be easily recycled. Effective awareness campaigns and strict policy-making are also crucial in gradually reducing pollution caused by idol immersion.

Attempts to control idol immersion pollution

Idol immersion during Hindu festivals such as Kali Puja, Durga Puja, Ganesh Chaturthi, and Diwali is a significant cause of water pollution in India. The idols are often made of non-biodegradable materials like Plaster of Paris, plastic, cement, and metals, and are decorated with toxic paints and heavy decorations. When immersed in rivers or lakes, these idols release harmful chemicals and heavy metals, such as lead and chromium, which pollute the water and damage the ecosystem.

To address this issue, several attempts have been made to control idol immersion pollution:

• Reverting to Traditional Materials: There are calls for a return to the traditional use of clay to make idols, as it is biodegradable and less harmful to the environment. Avoiding non-clay materials and harmful chemicals can help reduce water pollution during idol immersion.
• Special Immersion Ponds: Some suggest creating designated artificial ponds or tanks specifically for idol immersion. By centralizing the immersion in controlled locations, the pollution can be contained and prevented from spreading to larger water bodies.
• Early Removal of Debris: Studies have shown that the early removal of immersed idols and associated materials from water bodies can lead to lesser pollution. Local authorities play a crucial role in promptly clearing the debris, minimizing the negative impact on water quality.
• Awareness and Education: Raising awareness among the public about the environmental impact of idol immersion is essential. Educational campaigns can promote the use of eco-friendly materials, natural dyes, and organic constituents for idols, reducing the overall pollution levels.
• Strict Policy-Making: Effective policy interventions and legal enforcement are necessary to regulate idol immersion practices. The Central Pollution Control Board in India has formulated guidelines to manage idol immersion and mitigate pollution, but strict adherence to these protocols is crucial.
• Alternative Rituals: While stopping religious rituals entirely is not feasible, modifications can be made. For example, encouraging the use of temporary water tanks built by municipal authorities or promoting alternative rituals that do not involve water immersion can help reduce pollution.

These attempts to control idol immersion pollution aim to balance religious traditions with environmental sustainability, ensuring that festivals can be celebrated without causing significant harm to aquatic ecosystems and human health.
