Plastic waste in water: sources and locations
Plastic water pollution refers to the harmful accumulation of synthetic plastic products in the environment. Plastic is a synthetic, organic polymer made from fossil fuels, such as gas and petroleum, and is used in almost all consumer and industrial activities. Over 460 million metric tons of plastic are produced every year, and an estimated 20 million metric tons of plastic waste end up in the environment annually.
Plastic waste in water comes from a variety of sources, primarily human consumption and industrial activities. Food containers and packaging are the largest components of municipal solid waste, accounting for 31.7% or 80 million tons. These items, along with plastic bags, are also the most common type of marine debris. Packaging and single-use disposable products are not only ubiquitous in marine debris but also represent an unsustainable use of precious resources such as oil, trees, energy sources, and water. The quantity of marine debris is increasing worldwide, with a five-fold increase in plastic debris in the Central Pacific Gyre between 1997 and 2007, and a ten-fold increase in plastic particles off Japan's coast between the 1970s and 1980s.
The problem of plastic waste in water is further exacerbated by the global trade of plastic products and waste to locations with insufficient infrastructure for safe and environmentally sound management. This results in the improper disposal of plastic waste, which ends up polluting natural environments. Population centres generate the most litter, and the low recovery rate of plastics compared to other materials contributes to the issue. Once plastic waste enters water systems, it is challenging to retrieve, especially once it breaks down into microplastics.
The impact of plastic waste in water is far-reaching, affecting all land, freshwater, and marine ecosystems. It contributes to biodiversity loss, ecosystem degradation, and climate change. Plastic pollution has been found in every corner of the globe, from Mount Everest to the Mariana Trench. It harms wildlife, with millions of animals killed by plastics every year, and possibly human health, as microplastics have been detected in human blood, placentas, food, drinks, and the air.
To address the issue of plastic waste in water, prevention is key. This includes reducing the generation of disposable products, improving waste management systems, promoting recycling, and redesigning products to consider the short life of disposable packaging. A global plastics treaty is also needed to reduce plastic production, phase out harmful subsidies, and eliminate harmful products and chemicals.

Impact on human health
Plastic pollution is a pressing environmental issue that has harmful impacts on human health. The toxic chemical additives and pollutants found in plastics threaten human health on a global scale. Plastic waste is persistent and can take hundreds to thousands of years to decompose, depending on environmental conditions. During this time, plastics can fragment into smaller pieces, known as microplastics, which have been found in human blood, lungs, placentas, and even faeces.
The health impacts of microplastics are an emerging area of research, and the full extent of their harm to humans is not yet fully understood. However, studies have found microplastics in food and drinks, including tap water, beer, and salt. These microplastics can act as vessels for pathogens, increasing the spread of diseases. Additionally, the chemicals found in plastics, such as carcinogens, can leach into water sources, leading to potential developmental, reproductive, neurological, and immune disorders in humans.
The transmission of vector-borne infectious diseases is one of the clearest examples of how plastic pollution negatively affects human health. Plastic debris provides a favourable breeding environment for vectors and pathogens, especially in areas with poor sanitation. This includes human pathogenic bacteria, mosquitoes transmitting Zika and dengue, and schistosome-carrying snails. As a result, the consumption of seafood, which may be contaminated with plastic particles and chemicals, could increase the exposure of these harmful substances to humans.
Furthermore, plastic pollution contributes to biodiversity loss and ecosystem degradation, which have indirect impacts on human health. It threatens food and water safety, burdens economic activities, and contributes to climate change. The build-up of plastic litter can negatively affect a country's economy and trade systems, impacting sectors such as small and medium enterprises, tourism, fisheries, and agriculture.
While the specific health effects of plastics on humans are complex to determine due to the global spread of plastic contamination, it is evident that the chemicals found in plastics are not healthy for humans. More studies are needed to fully understand the potential long-term health consequences of microplastics and plastic pollution on human health.

Impact on wildlife and ecosystems
Plastic pollution is a pressing global issue that poses a grave threat to wildlife and ecosystems. It affects all land, freshwater, and marine ecosystems, including lakes, rivers, and seas. The impact of plastic pollution on wildlife and ecosystems is extensive and far-reaching, causing harm in multiple ways.
One of the primary ways plastic pollution harms wildlife is through ingestion. Birds, whales, fish, and turtles often mistake plastic waste for food, leading to fatal consequences. According to Clean Water Action, plastic pollution has impacted at least 267 species worldwide, including 86% of all sea turtle species, 44% of seabird species, and 43% of marine mammal species. The ingestion of plastic waste can lead to starvation as their stomachs become filled with indigestible material. Additionally, microplastics, which are small plastic particles, have been found in municipal drinking water systems and are being consumed by humans and animals, with unknown health consequences.
Another significant impact of plastic pollution on wildlife is entanglement. Animals such as seals, whales, turtles, and birds can become trapped in abandoned fishing gear, discarded six-pack rings, or other plastic waste, rendering them vulnerable to prey and unable to hunt for food. This often results in injury or death.
Plastic pollution also alters habitats and natural processes, reducing ecosystems' ability to adapt to climate change. It contributes to the degradation of ecosystems and biodiversity loss. For example, healthy mangroves provide coastal protection, while wetlands are essential for freshwater provision. Plastic pollution threatens these vital ecosystems and the species that depend on them.
Furthermore, plastic waste can release toxic chemicals into the soil and water. These chemicals, such as those found in certain plastic products or fireproofing coatings, can contaminate groundwater and other water supplies, harming both ecosystems and animals that consume the water. The presence of carcinogenic chemicals in plastic pollution poses a significant risk to the health of exposed ecosystems and individuals.
The impact of plastic pollution on wildlife and ecosystems is a global concern that requires immediate attention. Efforts to reduce plastic production, improve recycling technologies, and promote sustainable alternatives are crucial to mitigating the harmful effects of plastic pollution on the environment and wildlife.
