Plastic In Your Diet: The Hindu's Startling Expose

Plastic is everywhere. In the oceans, soil, air, lakes, and rivers. And, increasingly, in our food and bodies. Research suggests people worldwide may be ingesting up to 5g of plastic particles every week, with microplastics found in tap and bottled water, beer, salt, shellfish, fruits, vegetables, meat, and packaged goods. Single-use plastic bottles, for example, break down into microplastics, which then find their way into our food and water. While the health impacts of this are still unknown, experts are concerned about the potential risks. So, what can we do to reduce our exposure to plastic?

Plastic in bottled water

Plastic pollution has become a defining concern of our time, with microplastics being found in all ecosystems, from ocean trenches to mountaintops. A recent study published in February 2024 revealed that a litre of bottled water can contain more than 100,000 particles of micro- and nanoplastics, with 90% being nanoplastics. Nanoplastics are minuscule, ranging from 1 nanometre to 1 micrometre in size.

This issue is not new. In 2018, Orb Media, a non-profit journalism organisation, conducted tests on more than 250 bottles from 11 brands, revealing contamination with plastics such as polypropylene, nylon, and polyethylene terephthalate (PET). The tests showed a global average of 10.4 plastic particles per litre, with some bottles containing more than 10,000 particles per litre. Plastic was found in 93% of the samples.

The presence of plastics in bottled water has significant implications for human health. While some bottlers, like Nestle, have conducted their tests and found lower quantities of micro-particles per litre, the impact of consuming even small amounts of plastics is not fully understood. Some studies suggest that microplastics can enter different parts of the body, such as the gut's lymphatic system or the kidneys and liver.

The health impact of consuming microplastics is a growing concern, and it is encouraging that organisations like the WHO have commissioned reviews to address this issue. However, the lack of specific regulations for microplastics in food and beverages in many countries, including the US, highlights the need for more comprehensive legislation to protect consumer health.

To address this global crisis, long-term solutions are necessary. Banning single-use plastic bags, enforcing waste management rules, and transitioning to a circular plastic economy that prioritises durability, reusability, and recyclability are essential steps. As consumers, we can also play a role by reducing our reliance on plastic products and choosing alternatives like glass, enamel, or foil for food storage.

Plastic in tap water

In 2018, Orb Media, a non-profit journalism organisation, revealed the presence of microscopic plastic in global tap water samples. The study found a global average of 10.4 plastic particles per litre for plastic particles in the 100-micron or 0.10-millimetre size range. These particles were confirmed as plastic using an industry-standard infra-red microscope. Even smaller particles were also detected, with a global average of 314.6 per litre.

The study collected samples from 19 locations in nine countries across five continents. While some bottles had no detectable plastic, one bottle contained a startling 10,000 particles per litre. Overall, 93% of the samples contained plastic.

These findings highlight the ubiquity of plastic pollution, which has infiltrated not only our tap water but also bottled water, oceans, soil, air, lakes, and rivers. The human body may be the final frontier for plastic, with microplastics potentially present in our tissues. While the health implications of this are not yet fully understood, experts express concern, particularly regarding the potential impact on foetuses and unborn children.

To reduce exposure to plastic in tap water, individuals can consider installing home filtration systems or using refillable containers with filters. Additionally, it is crucial to minimise the use of single-use plastics and properly dispose of or recycle plastic waste to prevent it from ending up in nature.

Furthermore, addressing the root cause of plastic pollution is essential. Governments and industries must work together to reduce plastic waste and develop more sustainable alternatives. This includes improving waste management systems and promoting reusable, recyclable, or biodegradable materials. By taking collective action, we can strive to protect our environment and our health from the detrimental effects of plastic pollution.

Plastic in food

Plastic is everywhere, from the depths of the ocean to the peaks of mountains, and it is increasingly becoming a part of our diet. Research has shown that people worldwide could be ingesting 5 grams of plastic particles every week, which is equivalent in weight to a credit card. These particles are making their way into our bodies through various food and beverage sources, with potentially harmful consequences.

Water, especially bottled water, is one of the primary sources of plastic ingestion. A study by Orb Media, a non-profit journalism organisation, found that a single bottle can contain dozens or even thousands of microscopic plastic particles. Tests on 250 bottles from 11 brands revealed contamination with plastics like polypropylene, nylon, and polyethylene terephthalate (PET). The global average was found to be 10.4 plastic particles per litre, with some bottles containing more than 10,000 particles per litre.

It's not just bottled water that's affected. Tap water samples from around the globe have also been found to contain microplastics. Additionally, plastic particles have been detected in shellfish, beer, and salt, tea, rice, and even in fruits and vegetables. A 2024 study revealed that 90% of animal and vegetable protein samples tested positive for microplastics, which can be absorbed by plants through their root systems.

The health implications of ingesting microplastics are still not fully understood. While some experts suggest that there is little health concern based on current knowledge, others believe that the presence of plastic in our bodies is likely to have negative effects. Research has already shown that these particles can migrate to various organs, including the liver, kidneys, and brain, and can even cross the placental boundary, impacting unborn children.

To reduce exposure to microplastics, experts recommend avoiding foods packaged in plastic and opting for reusable containers made from natural materials like glass, enamel, or foil. Reusable totes and produce bags can be used for grocery shopping, and single-use plastics like shampoo bottles and bubble wrap can be replaced with more sustainable alternatives.

While individual actions are important, addressing the broader issue of plastic pollution is crucial. The production and consumption of plastic have increased significantly in recent decades, with a substantial amount ending up as waste in nature. Countries like China and India have been identified as major plastic polluters, and improving waste management systems is essential to mitigate this global issue.

Plastic in the environment

Plastic pollution is a pressing issue that has attracted the concern of scientists, governments, and environmental organizations like the United Nations Environment Program (UNEP). The primary concern is that plastic is not biodegradable, and thus, plastic waste is accumulating in the environment, causing pollution and affecting human health.

A significant source of plastic pollution is the improper disposal of plastic products, such as plastic bags, bottles, and packaging materials. These items are often discarded in open storm water drains, on streets, and in natural environments like oceans, rivers, and lakes. The problem is exacerbated by the fact that much of the plastic we discard is not recycled or incinerated in waste-to-energy facilities. Instead, it ends up in the soil and the sea, contributing to environmental degradation.

The impact of plastic pollution is far-reaching. Recent studies have found microplastics, or particles smaller than 5 millimeters, in various environmental samples, including oceans, soil, air, lakes, and rivers. Plastic particles have even been discovered inside fish in the deepest parts of the ocean and in the snow-capped Pyrenees mountains between France and Spain. This indicates that plastic pollution is pervasive and has infiltrated even the most remote and pristine areas of nature.

The presence of microplastics in the environment has significant implications for human health. While the full extent of the health risks is not yet known, it is concerning that microplastics have been detected in global tap water and bottled water sources. Additionally, plastic particles have been found in various food items, such as shellfish, and beverages like beer. According to researchers, people worldwide may be ingesting up to 5 grams of microscopic plastic particles every week, which equates to approximately 250 grams per year.

To address the issue of plastic pollution, it is essential to reduce plastic consumption and promote sustainable waste management practices. Individuals can play a crucial role by reusing plastic items instead of discarding them after single-use and opting for reusable bags and containers made from alternative materials like glass and steel. Governments and organizations must also step up by implementing comprehensive waste management systems and promoting recycling initiatives.

Reducing plastic consumption

Research has shown that people worldwide could be ingesting up to 5 grams of plastic particles every week, with plastic being found in 93% of water samples. The average American is estimated to consume about 45,000 plastic particles smaller than 130 microns annually, not including the particles they breathe in.

Given the prevalence of plastic in our daily lives, it is important to take steps to reduce plastic consumption and waste. Here are some ways to achieve this:

Reusable alternatives

One way to reduce plastic consumption is to opt for reusable alternatives. Instead of single-use plastic bags, consider using reusable tote bags for grocery shopping, just like our grandparents did. Bring your own bags, usually made of cotton or jute, and wash and dry them for future use. Reusable water bottles are also a great way to reduce plastic waste and limit your exposure to microplastics.

Reduce, reuse, recycle

Don't discard plastic bottles and bags after a single use; instead, find ways to reuse them. For example, plastic bottles can be used as plant watering cans or for storing liquids like paint or detergent. Additionally, focus on recycling plastics to produce new products or fuels.

Choose glass, steel, and natural materials

Increase your use of glass and steel products in your daily life. Opt for food and drinks stored in glass, enamel, or foil packaging instead of plastic. When it comes to clothing and consumer products, choose natural fabrics and materials, like cotton or jute, over synthetic ones.

Avoid plastic in the kitchen

Try to avoid using plastic in the kitchen. Don't microwave food in plastic containers, as the heat can cause the plastic to break down and leach chemicals into your food. Instead, use glass or ceramic containers that are safer alternatives.

Beware of hidden plastics

Plastic can be found in unexpected places, such as salt, sugar, tea bags, and even rice. Be mindful of these hidden sources of plastic and try to reduce your consumption or opt for plastic-free alternatives.

By following these steps and making conscious choices, we can significantly reduce our plastic consumption and work towards a healthier and more sustainable future.
