Microplastics found in plaques that accumulate in coronary arteries
by Dr Harold Gunatillake,
OAM, FRCS, FIASC, FICS, AM(Sing), and MBBS(Cey), a Health writer, compiled this.
Overview:
This document concerns microplastics’ presence, potential health risks in the human body, and the environment, and strategies to reduce plastic pollution.
People with microplastics and nanoplastics in plaque lining a major blood vessel in their neck may have a higher risk of heart attack, stroke or death, new research suggests.
Living in developed countries today comes with health hazards caused by consuming unhealthy diets. Regular consumption of hot foods, street foods, and highly salted processed fatty fried foods can lead to clogging of arteries, which increases the incidence of cardiovascular disease and stroke. In the past, our parents used to cook our meals in clay pots. They would cook the food by boiling it in water in such utensils and then temper it for taste; subsequently, the healthiest procedure of cooking food. However, today, in the fast-food world, all foods are fried in cooking oil for convenience and taste, which is not healthy, causing many health problems.
This modern lifestyle has led to numerous health issues, such as obesity, cardiovascular disease, diabetes, and cancer, among others.
Another new health hazard.

Unfortunately, we now face another health hazard caused by using polythene bags to wrap food items instead of paper bags, as was the case in the past. Microplastics, plastic fragments less than 5mm long, pollute natural ecosystems through various sources, including cosmetics, clothing, food packaging, and industrial processes. Supermarkets commonly use polythene bags to package food items, contributing to this pollution.
Microplastics are particles smaller than five millimetres, while nanoplastics are even smaller, so they can only be seen using specialised microscopes. Over the years, these particles have become widely present, and their existence can no longer be denied. They have been discovered in fresh snowfall in the Antarctica, at the depths of the Marianas Trench, as well as in human blood, breast milk, urine, and placental, lung, and liver tissue. Since 1980, global plastic production is estimated to have accounted for 8.3 billion metric tonnes (MTs), over half of which has been discarded after a single use.
The National Oceanic and Atmospheric Administration and the European Chemicals Agency found that microplastics hurt the environment.
Water is one of the worst sources of microplastic. A person who drinks only bottled water would ingest around 130,000 microplastic fragments yearly from that source alone.
Microplastics did not appear phytotoxic to wheat because 19% of the antioxidant system was stimulated, 2% of the morphology was reduced, and 4% of the photosynthesis was inhibited.
Some animals mistake the particles for food, while others ingest them when they consume animals that have eaten them. So, are these microplastics harmful to other animals and us?
Significant levels of microplastics pollute the ocean, freshwater, and land, and research shows that animals, including humans, eat these microplastics. (sciencelearn.org.nz)
DAVID NIELD, a Journalist, writes on HEALTH, 5 March 2024, that tiny fragments of microplastics are making their way deep inside our bodies in concerning quantities, significantly through our food and drink.
There’s a Surprisingly Simple Way to Remove Microplastics From Your Drinking Water
Scientists have now found a simple and effective means of removing them from water. A team from Guangzhou Medical University and Jinan University in China tested soft and hard tap water (richer in minerals), adding nanoplastics and microplastics (NMPs) before boiling the liquid and filtering out any residues.
Microplastics are tiny plastic particles that can end up in the environment and be ingested or inhaled by people.
A recent study found that nearly 60% of people undergoing surgery had microplastics or smaller nanoplastics in a main artery. Those with these particles were 4.5 times more likely to experience heart attacks, strokes, or death within approximately 34 months after the surgery compared to those with plastic-free arteries.
Dr. Raffaele Marfella, a cardiology researcher at the University of Campania Luigi Vanvitelli in Naples, Italy, led a new study to identify new risk factors for cardiovascular disease. The study was initiated due to the increasing amount of degraded plastic pollution in the environment. Dr. Marfella and his colleagues wondered whether micro- or nanoplastics could harm our arteries. These tiny plastic particles can enter the body through ingestion, inhalation, or skin contact.
Although the study is inconclusive, it raises concerns about the potential impact of microplastics on cardiovascular health and plaque buildup in blood vessels. Here are some general strategies that may help promote cardiovascular health and potentially reduce the risk of plaque buildup in blood vessels:
It is essential to keep in mind that making specific lifestyle changes can have a significant impact on our overall health. While researchers are still uncovering the potential adverse effects of microplastics, it is always a good idea to adopt heart-healthy habits that can improve the health of our cardiovascular system and potentially reduce the risk of plaque-related issues. Microplastics can come from different sources, both directly and indirectly. Let’s take a closer look at some of these sources.
“Plastic pellets, also known as pre-production pellets or nurdles, are small granules of plastic used to create various plastic products. These pellets are slow to degrade and can easily enter the environment, posing a significant risk to marine and human life. Due to their small size, they can be ingested by fish and birds, which can disrupt the food chain and harm the health of both animals and humans.”
Personal Care Products:
Some products, such as exfoliating scrubs and toothpaste, contain tiny plastic microbeads. These beads can wash down drains and end up in water bodies.
Paint:
Paint particles can release microplastics during weathering and erosion.
Washing Wastewater:
Synthetic fabrics shed microfibers during washing, contributing to microplastic pollution.
Sewage Sludge:
Sewage treatment plants can accumulate microplastics from various sources.
Plastic Running Tracks and Artificial Turf:

These materials can degrade over time, releasing microplastics.
Rubber Road Surfaces:
Tire wear on roads can generate rubber particles, contributing to microplastic pollution.
Vehicle Tyre Wear:
As vehicles increase globally, tyre wear becomes a significant source of environmental microplastics.
Municipal Debris:
Items like plastic bags and bottles break into smaller particles over time.
Fishing Wastes
: Discarded fishing gear, including nets and lines, can fragment into microplastics.
Agricultural plastics, such as mulch films, can break down into tiny pieces, while more oversized plastic items eventually become microplastics under natural conditions. Of all these sources, increasing vehicle tyre wear is particularly concerning. However, research on the presence of rubber particles in the environment is still limited. Proper management of plastic waste and wastewater is essential to prevent and control the pollution caused by microplastics in the future.
Remember that addressing microplastic pollution requires collective efforts to safeguard our environment and health, from individual choices to policy changes.
Reducing plastic pollution is vital for our planet’s health. Here are some practical steps we can take:
Wean Yourself Off Disposable Plastics:
Did you know that about 90% of the daily plastic items are used once and then thrown away? These include grocery bags, plastic wraps, disposable cutlery, straws, and coffee cup lids. However, we can all do our part to reduce plastic waste by using reusable alternatives. Consider bringing your bags when shopping, carrying your silverware to work, and using a travel mug for your coffee. Small steps like these can make a big difference in creating a more sustainable future.
Stop Buying Bottled Water:
Close to 20 billion plastic bottles end up in the trash each year. To avoid single-use plastic bottles, carry a reusable water bottle with you. If you’re concerned about tap water quality, choose a bottle with a built-in filter.
Here are some tips to reduce plastic usage and help protect the environment:
Microbeads are tiny plastic scrubbers commonly used in facial scrubs, toothpaste, and body washes. However, these little plastic particles can easily pass through water treatment plants and harm marine animals. It’s best to avoid using products containing microbeads and instead opt for natural exfoliants like oatmeal or salt. Boycotting microbeads is an effective way to protect our planet and its inhabitants.
Cook More:
Preparing meals reduces reliance on takeout containers and plastic doggy bags. When ordering takeout or eating out, decline plastic cutlery. For extra credit, bring your food-storage containers to restaurants for leftovers.
Purchase Secondhand Items:

According to the U.S. National Oceanic and Atmospheric Administration and the European Chemicals Agency, microplastics are fragments of any type of plastic less than
five mm in length. They pollute natural ecosystems by entering them from various sources, including cosmetics… Wikipedia
Buying secondhand reduces the demand for new plastic packaging. Check out thrift stores or online platforms for toys, gadgets, and other items.
Improve Plastic Product Design:
We can also improve the design of plastic products. This could include using more eco-friendly materials or developing better recycling systems. Encourage reusable and refillable options. Redesign plastic products to provide more opportunities for reuse and refilling.
Increasing Solid Waste Collection is crucial to ensure effective waste management and prevent plastic pollution from adversely impacting communities. We should also advocate for fewer single-use plastic products and reduce pollution from plastic production facilities. Remember that every small action counts. By making conscious choices collectively, we can significantly reduce plastic pollution and protect our environment.
“The issue of microplastic pollution has received little attention so far. However, addressing this problem before it becomes a major, uncontrollable issue is important. This pollution can adversely affect our environment and individual health, mainly cardiovascular health. Therefore, it is crucial to take action and prevent this demon from causing more damage.”

Dilemmas of ‘hurting economies’ – the case of Sri Lanka
Maldives President Dr. Mohamed Muizzu was in Sri Lanka recently on what was apparently a goodwill visit and this event, no doubt, bodes very well for Maldives-Sri Lanka relations. Besides, the visit would go some distance in strengthening Sri Lanka’s claims to Non-Alignment.
However, the commentator on regional politics could be accused of simplistic thinking if he/she glosses over or ignores the regional politics nuances or undertones of the Maldivian President’s visit. In Sri Lanka we currently have a government which is eager to solidify its bridges, so to speak, with China and which, given the chance, would be courting increasingly close relations with Russia. In other words, the NPP government is likely to see itself as a ‘natural ally’ of the East and would prefer to distance itself to the extent possible from the West, if that is a realistic proposition.
Given the foregoing backdrop, it would be in some of the NPP regime’s best interests to be on cordial terms with the Maldives which is a close ally of China in the South Asian region. However, the NPP government, given the utter financial helplessness of Sri Lanka, cannot afford to distance itself politically and diplomatically from India and the West. Sheer economic necessity compels Sri Lanka to adopt this foreign policy stance. In other words, the latter has no choice but to be ‘Non-Aligned.’
This columnist was led to the above observations on listening to a lucid and comprehensive presentation titled, ‘A Global Economy in the Shadow of the Iran War and implications for Sri Lanka’s debt recovery’, by Dr. Ganeshan Wignaraja, Visiting Senior Fellow, ODI Global London, at the Regional Centre for Strategic Studies (RCSS), Colombo on May 4th. The forum, RCSS Strategic Dialogue – 4, was moderated and presided over by RCSS Executive Director Ambassador (retd) Ravinatha Aryasinha.
The forum brought together a wide cross section of society, including diplomatic personnel, academicians, public and private sector personalities and the media. After the presentation a very lively and informative Q&A followed.
Ambassador Aryasinha at the outset set an appropriate backdrop to the presentation and discussion by stressing ‘the increasing interconnectedness of geopolitical and economic developments, noting how disruptions in the Middle East could have significant ramifications for global markets, trade flows, energy prices and broader economic stability, including Sri Lanka.’
Indeed, there are occurring currently very disruptive economic and material consequences for the world from ‘the Iran War’, and with US-Iran hostilities spiraling in West Asia it may not be wrong to surmise that the worst could be yet to come, unless a peace process materializes in earnest.
Meanwhile, ‘hurting countries’ such as Sri Lanka would need to summon their best economic management capabilities to remain materially and economically afloat. ‘Economic transformation’ is what is urgently needed and not mere management and some of the insights thrown up by Dr. Ganeshan Wignaraja should have the local polity thinking.
There was the following observation, for instance: ‘Sri Lanka has achieved remarkable cyclical stabilization but faces critical challenges in transitioning to transformative growth, with 2027-2028 debt repayments looming and only $5.4 billion usable reserves.’
Needless to say, the path ahead to ‘transformative growth’ for Sri Lanka is strewn with multiple challenges and meeting them effectively is of the first importance. Sri Lanka must soldier on towards even a semblance of development in the short and medium terms and such initiatives cannot be separated from its foreign policy choices since the country’s economic partners and their growth prowess have a close bearing on the country’s material fortunes.
As mentioned, Sri Lanka will be compelled to be ‘a friend of all countries and an enemy of none’ going forward but it cannot afford to be seen as cultivating China as a close growth partner at the expense of India and other major economies of the region.
This is primarily because while India is remaining a major economic power, the current West Asian crisis notwithstanding, China’s economy is being seen as ‘slowing’. Dr. Wignaraja singled out the following in the main as the factors causing this slow-down: a bursting property bubble, increasing state regulation, and weakening investor confidence. Besides, the speaker sees production cycles moving away from China and India replacing China and Hong Kong as ‘manufacturing hubs’.
Accordingly, the NPP regime in Sri Lanka would need to craft its regional policy in particular with the utmost far-sightedness. It will need to have close economic links with all the growth centres that matter.
On the question of authentic economic transformation, the following observations of Dr. Wignaraja on Sri Lanka’s economy are of the first importance as well: ‘Foreign reserves are now at $ 5.4 billion, the cost of living is high, an estimated 20 per cent of the population lives below the poverty line of $ 3.65 per day, the recent cyber security breach at the Treasury would affect some 10 payments.’ These factors were termed ‘critical vulnerabilities’.
It is difficult to conceive of an economic transformation worthy of the phrase minus a steady economic empowerment of the populace. The above data point to the considerable magnitude of the local poverty problem. Right now, the disruptive effects of the West Asian crisis render swift poverty alleviation a most difficult proposition.
One possible way out of the present economic debacle is the forging of a national consensus by the present government on all outstanding problems that have been bedeviling the country’s advancement. That is, there needs to be a meeting of minds across current political divides. Considering the present inflammatory political polarities in Sri Lanka this would prove an insurmountable challenge.
Unfortunately, conscience-filled and civic minded sections in Sri Lanka have chosen to be laid back rather than seize the initiative, come centre stage and impress on politicians the need for enlightened governance and progressive change. There needs to be a historic coming together of the right thinking to ensure that the best interests of the people and of the people only are served by governments. In the absence of such a process, might would be projected as right and brute force would come to increasingly rule politics and society.

Australia funds project to restore climate-resilient vegetable livelihoods in cyclone-affected highlands
The Ministry of Agriculture, Livestock, Lands and Irrigation, the Government of Australia, and the Food and Agriculture Organization of the United Nations (FAO) have launched of a AUD 2 million (USD 1.4 million) recovery initiative to restore and transform vegetable production systems in the cyclone-affected districts of Nuwara Eliya and Badulla.
The FAO said yesterday (5) that the agreement was formalized through the signing of the grant agreement by Matthew Duckworth, Australian High Commissioner to Sri Lanka, and Vimlendra Sharan, FAO Representative for Sri Lanka and the Maldives, alongside the signing of the project document by D. P. Wickramasinghe, Secretary of Agriculture.
Cyclone Ditwah, which struck Sri Lanka in November 2025, caused widespread devastation across the country, severely disrupting agricultural production systems and livelihoods. The highland districts of Nuwara Eliya and Badulla, key suppliers of vegetables such as beans, carrots, leeks, cabbage, tomato and potato, were among the hardest hit, with thousands of smallholder farmers losing crops, seed stocks, and productive assets.
This 12-month initiative aims torestore and strengthen climate-resilient vegetable production systems, with a strong focus on empowering women farmers and supporting persons with disabilities. The project will directly benefit more than 2,400 smallholder farmers, through improved seed and seedling production systems, small machinery, training, and market linkages while indirectly supporting thousands more.
“This initiative is an important step not only in restoring what was lost, but in building a more resilient and self-reliant agricultural sector,” said Minister Lal Kantha. “By strengthening local seed systems and supporting smallholder farmers, particularly women and vulnerable groups, we are investing in the long-term sustainability of Sri Lanka’s food systems.”
“Australia stands alongside Sri Lanka in its ongoing recovery from Cyclone Ditwah,” said High Commissioner Duckworth. “Australia is a steadfast partner in the agriculture sector with its importance for food security, rural development and climate resilience. By focusing on climate smart practices, farmer-led solutions and inclusive economic opportunities, this project will deliver meaningful and lasting benefits to affected communities.
The project will prioritize the restoration of farmer-led seed systems for beans and potatoes, support the re-establishment of both open-field and protected cultivation systems and women led seedling supply nurseries while empowering all farmers with Climate-Smart Good Agricultural Practices (CSGAP) with small scale machinery and input support.
A key feature of the initiative is the establishment of six accessible and inclusive nurseries in Nuwara Eliya and Badulla. These nurseries will serve as sustainable agri-based enterprises, producing high-quality vegetable seedlings while creating new income opportunities and strengthening local input supply chains.
By combining recovery support with long-term resilience measures, the project will help stabilize vegetable production, improve household food security and nutrition, and reduce reliance on imported seeds.

War on Iran may hasten unraveling of New World Order
It took several decades for the US to realise it was losing the war in Vietnam. It took a bit shorter time in Afghanistan. And what is happening in the countries the US and Israel intervened and broke up? The US has been asked to leave Iraq. Syria is talking to Russia about establishing military bases, President al-Sharaa met with Vladimir Putin in Moscow to discuss the project, which is vital for Russian power projection in the Middle East. Libya has been divided into two competing administrative units with the Eastern section actively engaged with Russia in defence matters. The Sudanese government has finalised a 25-year deal to allow a Russian naval facility in the Red Sea in exchange for weapons, including anti-aircraft systems. On the Eastern side of the Red Sea, Yemen remains divided, with the main power center, the Houthis maintaining a staunchly anti-US, anti-Israel stance, while the internationally recognised government remains in exile.
When the Iranian Foreign Minister recently undertook a tour of Pakistan, Oman and Russia, the US wanted to meet him and got ready to send its negotiators Vice President J. D. Vance and his team to Pakistan, but Iranian FM snubbed them and left Pakistan, saying Iran did not want to talk to the US while a blockade of their ports were in place. The Iranian FM met President Putin, who congratulated Iran for courageously defending their country and then phoned US President Trump and told him further attacks on Iran would not be acceptable. During this conversation on April 27, 2026, Putin reportedly warned Trump that further U.S. or Israeli attacks on Iran would have dangerous consequences, according to Al Jazeera). Such a sequence of events would not have been possible in the unipolar world we had in the past.
Furthermore, the damage that Iran has inflicted on the US and Israel in this war would have been unimaginable in the late 20th Century and early 21st Century. Sixteen US military bases spread across Saudi Arabia, Qatar, UAE, Bahrain, Kuwait, Iraq, Jordan and Oman have been either destroyed or severely damaged. Advanced surveillance aircraft and radar systems worth more than $ 2.8 bn were destroyed. This had a far-reaching effect on the war as the US could not use these bases in the war against Iran and also in the defence of its allies in the Gulf.
The attacks on Israel have been equally damaging. In Central Israel and Tel Aviv area multiple attacks targeted military and intelligence assets, resulting in massive damage. Iranian missiles hit the Haifa oil refinery, causing a shutdown, and hit residential buildings, leading to injuries and structural damage. Residential and commercial areas were damaged in Bat Yam and Petah Tikva with significant casualties and destruction. Attacks in Dimona and Arad targeted the Negev Nuclear Research Center, with casualties reported in both towns. The Soroka Medical Center in Beersheba was hit in a strike. The strategic port and naval base in Eilat were targeted. In Rishon LeZion suburban residential areas suffered extensive damage.
Usually, Israel makes short work of its many enemies in the region, for example it took just six days to defeat the combined military of Egypt, Jordan and Syria in 1967 and grab their land as well. Hamas, Fatah and Palestinians would suffer ignominious defeats if they dare challenge Israel. However, the recent war against Hamas, following a daring wide scale invasion into Israel by Hamas in October 2023, went on for more than two years with no conclusive victory for Israel.
These significant massive military setbacks suffered by the combined forces of the US and Israel have been made possible by the unprecedented advancement in military technology achieved mainly by China and to a degree by Russia as well. Iran has been able to develop ballistic missile systems that could penetrate the “iron dome” that Israel boasted, with technological assistance from China and North Korea. Iran’s drones are very cheap yet very effective, requiring interceptors worth millions of dollars to counter them, thus making it much more costly for the US to fight this war than it is for Iran.
Further, Hezbollah in Lebanon, Houthies in Yemen and Hamas in Palestine are well equipped with advanced missiles and drones. Hezbollah has been able to destroy about hundred Israel tanks and stop their advance. According to Larry Johnson, former CIA intelligence analyst, Israel soldiers are much war weary and mentally affected and are being withdrawn. Netanyahu’s 40 year dream of a “Greater Israel” is telling on the poor soldiers.
If a person like Barack Obama had been the US President instead of the hyper egoistic, blustering, intellectually barren Trump, things may have been different. An attempt would have been made to reconcile with the fact that the world is changing, instead of trying to stop it and make “America Great Again”. Perhaps, it could be said that Trump is facilitating the emergence of the new world order by enabling the US citizens to see the reality, the futility of war and the fact that Israel is a liability because the US is fighting its war. Further, the war has enabled Iran to assert its place in the region and negotiate from a position of strength.
Perhaps, Israeli people may realise that the Palestine problem cannot be solved by militarily occupying their land, and that in a changing world a “Greater Israel” is a “pie in the sky”. They may have to agree to a two-state solution. US support may not always be forthcoming, certainly not at the level that Trump could extend, as this war is very unpopular and expensive. The other very significant fact is that Israeli settlers in the occupied lands feel insecure and one in three wants to leave and the numbers may grow when Palestinians and their sympathisers grow in strength in the new world order.
Moreover, the war on Iran has afforded China the opportunity to demonstrate with authority the fact that it stands for universal peace and does not tolerate illegal wars. Its message to the US conveyed its world view and its desire for peace in no uncertain terms. Trump cannot afford to disregard the Chinese position on the war on the eve of his visit to that country which may decide on future trade between the two countries as the US depends on China for several essential materials like rare earth minerals. Furthermore, China has shown that peace could be achieved by developing the economies of the underdeveloped countries irrespective of their alliances. It helps Iran as well as Saudi Arabia and try to build bridges between these foes. It welcomes Trump in the coming weeks and hopes to strengthen ties between the two countries despite the weaknesses of the latter.
Another important factor is the gradual decline of the critical value of the petro-dollar. Following the end of the gold standard in 1971, the US struck deals with Saudi Arabia and other OPEC nations (around 1974) to price oil exclusively in USD in exchange for military protection and arms sales. Dollars earned by selling oil came to be known as petro-dollar. Oil producers, holding large dollar surpluses, reinvest these funds in the US Treasury securities, real estate, and financial assets ensuring the recycling of petro-dollars. The system ensures a consistent global demand for US dollars, which helps fund the US budget deficit and maintains the currency’s dominance.
However, the petro-dollar system is on the decline and there are two main reasons for this, firstly the gradual rise of the new world order with organisations like BRICS, making a concerted effort to extricate from the dollar dominance by developing alternate currencies and methods to bypass the dollar. Secondly, the need felt by most countries to develop alternative energy sources to replace enormously harmful fossil fuel would eventually result in a decline in the demand for it and consequently the effectiveness of the petro-dollar. China is leading the world in both these endeavours; depolarisation process and renewable energy production. The war on Iran seems to have hastened the process of depolarisation as Iran insists that it will sell its oil for yuan only.
These revolutionary changes in the aftermath of the Iran war have their undeniable implications for the Global South, where more than 60% of the poor live.
