Plastic Pollution In Thames: A River's Sad Tale

The River Thames has some of the highest recorded levels of microplastics in the world, with a recent study showing that the Thames has higher quantities of microplastics than the Rhine, Danube, Po and Chicago Rivers. The plastic waste in the Thames is having a devastating impact on marine life, with species such as crabs ingesting microplastics from sanitary pads, balloons, elastic bands and carrier bags. The issue of plastic pollution in the Thames is made worse by the millions of single-use gloves and masks used during the Covid-19 pandemic, and the 11 billion wet wipes used in the UK every year, many of which end up in the river. Despite the scale of the problem, there is currently no statutory monitoring of the impact of plastic on UK rivers.

The Thames has some of the highest recorded levels of microplastics in the world

The River Thames has some of the highest recorded microplastic levels globally, according to a study. The river, which runs through London, is home to 125 species of fish and other wildlife. However, the high levels of microplastics in the Thames are cause for concern.

Microplastics enter the Thames through various sources, including the breakdown of larger plastics such as packaging and bottles, and fibres from washing machine outflows and sewage outfalls. Single-use plastic items, such as food wrappers, cotton bud sticks, drink bottles and lids, cups, and takeaway containers, also contribute significantly to the problem. In fact, between April 2016 and December 2019, a total of 97,019 drink bottles were recorded and removed from the river.

The presence of microplastics in the Thames has severe ecological consequences. Animals living in the river, such as crabs, ingest microplastics, which can harm their health. Microplastics can also physically alter the riverbed, changing the shape and sediment type of the foreshore. This not only affects the species living in and around the Thames but also those in the seas that the river feeds into.

While the Thames faces a significant microplastic pollution problem, it is important to note that it is not the only river affected. Studies have shown that other rivers, such as the Yangtze in China, also have high levels of microplastic pollution. Additionally, river pollution from chemicals such as trace metals has been largely addressed in the Thames due to successful environmental campaigns, providing hope that plastic pollution can also be reduced with similar efforts.

To address the issue of microplastics in the Thames, experts have called for stricter regulations on the labelling and disposal of plastic products. Community initiatives, such as the Thames River Watch citizen science programme, also play a crucial role in monitoring plastic pollution and educating the public about the impact of plastic waste. By working together, it is possible to reduce the amount of microplastics in the Thames and mitigate their harmful effects on the environment.

The Thames has higher quantities of microplastics than the Rhine, Danube, Po and Chicago rivers

The River Thames has some of the highest recorded levels of microplastics of any river in the world. It has a higher density of microplastics than the Rhine, Danube, Po and Chicago rivers.

Scientists have estimated that 94,000 microplastics per second flow down the Thames in places. The density of microplastics in the river was found to be 19.5 plastics per cubic metre. This exceeds the levels recorded in the Rhine in Germany, the Danube in Romania, the River Po in Italy and the Chicago River in the US.

The high levels of microplastics in the Thames are thought to be due to the break-down of large plastics, with food packaging believed to be a significant source. "Flushable" wet wipes were also found in high abundance on the shoreline, forming what researchers described as "wet wipe reefs". These products are physically changing the shape and sediment type of the foreshore across six sites. Single-use plastic items make up 83% of all counted items on the foreshore (excluding glass fragments).

The Thames is cleaner than it used to be with respect to some pollutants, such as trace metals. However, the high levels of microplastics are severely polluting the river and threatening wildlife. Crabs along the river have been found to have consumed small items of plastic, with an examination of 135 crabs resulting in 874 pieces of plastic being removed from their bodies.

The Thames sees millions of single-use masks and gloves from the Covid-19 pandemic

The River Thames is heavily polluted with plastic waste. In fact, it has a higher density of microplastics than several other major rivers in the world. A study by Royal Holloway, University of London, found that more than 94,000 microplastics flow down some sections of the Thames in London every second. These microplastics include plastic fragments, glitter, and microbeads, which have been found in water samples taken from Putney and Greenwich. The contamination of the Thames by plastic is a major issue, with plastic waste being ingested by wildlife and having a negative impact on the health of the river and its inhabitants.

The Covid-19 pandemic has likely exacerbated the problem of plastic pollution in the Thames. The increased use of single-use plastic items, such as masks and gloves, and the inappropriate disposal of these items, may have contributed to the high levels of plastic pollution in the river. Thames Water has reported an increase in wet wipe-related blockages of sewer systems during the pandemic, and it is likely that these products are also ending up in the Thames.

The pandemic has seen a significant increase in the use of personal protective equipment (PPE), including single-use masks and gloves. While these items are important for preventing the spread of the virus, they are also contributing to the plastic pollution crisis. Many of these items are made from non-biodegradable materials, such as polypropylene, and can take hundreds of years to break down. When disposed of improperly, they can end up in rivers like the Thames, where they can have devastating effects on the ecosystem.

The impact of the pandemic on plastic pollution in the Thames is not yet fully understood, as Covid-19 restrictions have limited fieldwork and research. However, it is clear that the pandemic has contributed to the already significant problem of plastic pollution in the river. In addition to masks and gloves, other single-use plastic items, such as food packaging and plastic-containing cleaning products, have also likely increased in usage during the pandemic. As a result, it is crucial that efforts are made to reduce plastic input into the Thames and other freshwater environments.

The pandemic has highlighted the importance of proper waste disposal and the need for alternatives to single-use plastics. It has also brought attention to the lack of statutory monitoring of the impact of plastic pollution on UK rivers. Organizations like Thames21 are working to address this issue by training volunteers to monitor plastic pollution and identify common plastic items. By understanding the sources and types of plastic pollution, we can develop effective solutions to reduce the amount of plastic entering the Thames and other waterways.

The Thames has 11 billion wet wipes lining its shores annually, renamed 'reef wipes'

The River Thames is one of the UK's most iconic waterways, but it is facing a significant threat from plastic pollution. An estimated 11 billion wet wipes line the shores of the Thames annually, earning them the nickname "reef wipes". This issue is not unique to the Thames, as plastic waste in rivers and oceans has become an increasingly prominent issue in recent years. The plastic waste is having a devastating impact on marine life and the freshwater ecosystem.

Wet wipes, in particular, have become a growing problem for the Thames. In 2019, 23,000 wet wipes were discovered along a stretch of the Thames riverbank, with an average density of 201 wet wipes per square meter. This has resulted in the formation of a "wet wipe island" near Hammersmith Bridge, which is the size of two tennis courts and over a meter deep in places. The buildup of wet wipes has even changed the course of the river.

Wet wipes often contain plastic, and when flushed down toilets, they can end up in rivers and on beaches, causing environmental damage. They contribute to the 30,000 blockages that occur annually in the UK, leading to increased water bills. Additionally, wet wipes can harm marine life, as fish may ingest them, leading to potential fatalities.

To address this issue, there have been calls for a ban on plastic wet wipes, with some retailers already introducing plastic-free alternatives. Increased public awareness is also crucial, as many people, especially those aged 18 to 24, are unaware of the consequences of flushing wet wipes. By putting wet wipes in the bin instead of flushing them, individuals can play a part in protecting the Thames and other waterways from plastic pollution.

The impact of plastic pollution in the Thames is not limited to wet wipes. Plastic consumer items and packaging, such as food wrappers, cotton bud sticks, drink bottles, and takeaway containers, are also commonly found in the river. Storms are likely contributing to the deposition of lightweight plastic items on the saltmarsh and reedbed habitats along the Thames. To effectively tackle plastic pollution, greater intervention is needed from the government and businesses, including standardized data collection protocols and legally binding waste reduction targets.

The Thames has 8,490 submerged plastic items, with 20% being sanitary products

Plastic pollution in the Thames is a pressing issue. A 2014 report in The Guardian revealed that scientists from the Natural History Museum and Royal Holloway, University of London, collected 8,490 plastic items from the riverbed of the upper Thames estuary over a three-month period. This included plastic cigarette packaging, food wrapping, and cups, amounting to a substantial quantity of plastic waste.

The issue of plastic pollution in the Thames has far-reaching consequences, impacting not only the river itself but also the marine life that inhabits it and the surrounding ecosystem. The plastic waste in the Thames is not limited to large items but also includes microplastics, which have been found in the stomachs of crabs and other organisms, posing a significant threat to their health and survival. The river has some of the highest recorded levels of microplastics globally, surpassing other major rivers like the Rhine, Danube, and River Po.

The primary sources of plastic pollution in the Thames are plastic consumer items and packaging. Single-use plastic items, such as food wrappers, cotton bud sticks, drink bottles, and takeaway containers, account for a significant portion of the pollution. Additionally, wet wipes are a significant contributor, with 11 billion used annually in the UK, many of which end up in the Thames, leading to the formation of 'wet wipe reefs' along the river's shores.

To address this issue, organisations like Thames21 have taken initiatives such as the Thames River Watch citizen science programme, which aims to train Londoners to monitor plastic pollution, identify common plastic items, and propose solutions. Despite these efforts, there is still a lack of statutory monitoring and comprehensive data collection on plastic pollution in UK rivers, highlighting the need for greater intervention from the government and businesses to tackle this pressing environmental issue.

The plastic pollution in the Thames is a pressing environmental concern, with submerged plastic items like sanitary products accounting for a significant portion of the waste. The high levels of microplastics and single-use plastic items pose a threat to the river's ecosystem and the diverse species that call it home, necessitating urgent and effective interventions to mitigate the problem.
