Littering: How It Pollutes The Air And Our Environment

Littering is a major problem that affects our environment in significant ways. When people litter, they are discarding waste incorrectly, whether that be dropping a gum wrapper on the ground or a company dumping toxic substances into a river. This waste ends up in our oceans, on our land, and in the air we breathe. It is estimated that around 40% of the world's litter is burned in the open air, releasing toxins that cause respiratory issues, health problems, and even acid rain. Animals are also affected, with over a million dying each year from ingesting or becoming trapped in litter.

Burning litter releases toxins into the air

The smoke from burning litter contains vapors and particulate matter, including solid and liquid droplets suspended in the air. These pollutants can cause eye and nose irritation, difficulty breathing, coughing, and headaches, especially for individuals with heart disease, asthma, emphysema, or other respiratory diseases. Additionally, certain chemicals released during the burning of litter can accumulate in the fats of animals and subsequently in humans through the consumption of meat, fish, and dairy products.

The burning of litter also contributes to environmental damage. Ash from burned litter can pollute the soil, groundwater, lakes, rivers, and streams. It can contaminate the soil and water sources, impacting the growth of plants and crops. Animals feeding on infected agriculture or crops contaminated with toxins can become sick, and these toxins can eventually enter the human food chain through the consumption of meat, dairy, and agricultural products.

Furthermore, the open burning of litter can lead to wildfires, posing risks to both the environment and public health. It can cause damage to properties and natural habitats, and it can also be challenging and costly to control and suppress these fires. Therefore, it is essential to follow state regulations and only burn approved materials to minimize the harmful effects of open burning.

Overall, the burning of litter has significant negative consequences for both the environment and human health, underscoring the importance of proper waste management and disposal practices to reduce the release of toxins into the air and mitigate the impact of air pollution.

Cigarette butts contain arsenic and formaldehyde, which are released into the air

Cigarette butts are the most common form of litter, with an estimated 4.5 trillion discarded every year worldwide. They are made from a kind of plastic called cellulose acetate, which is an environmental hazard in itself. However, the toxic chemicals in cigarettes are also released into the environment when cigarette butts are littered.

Cigarettes contain over 7,000 chemicals, including arsenic and formaldehyde, which are poisons that can make their way into the soil and freshwater sources, negatively impacting humans and animals. Arsenic, for example, is a chemical used in rat poison and insecticides, while formaldehyde is used in embalming fluid. When burned, cigarettes create more than 7,000 chemicals, at least 69 of which are known to cause cancer, and many are toxic or poisonous.

The act of littering itself contributes to air pollution, as approximately 40% of the world's litter is burned in the open air, releasing toxins. These toxins can cause respiratory issues and other health problems and can even contribute to acid rain.

The toxic chemicals in cigarettes can also be released into the environment through cigarette butt waste. The residues of chemical products used during tobacco growth and cigarette manufacturing may be found in cigarettes, and over 4,000 chemicals may be introduced to the environment through cigarette smoke and particulate matter. These chemicals include arsenic, formaldehyde, carbon monoxide, ammonia, acetone, and benzene.

In addition to the direct release of toxins through burning litter, the accumulation of litter in the environment can also have indirect effects on air quality. For example, plastic litter can break down into microplastics, which can enter the air and be inhaled by humans and animals.

Decomposing litter releases hazardous chemicals

Secondly, the chemical composition of litter plays a crucial role in the decomposition process and the release of hazardous chemicals. Litter is composed of various organic compounds, including sugars, phenolics, hydrocarbons, and glycerides, with differing proportions based on the plant part and species. The quality of litter, determined by its chemical composition of nitrogen, phosphorus, potassium, lignin, cellulose, and hemicelluloses, influences the decomposition rate and the release of chemicals. For example, lignin, a flexible molecule, can account for up to 50% of litter quantity and significantly impact decomposition.

Additionally, the type of litter and the site conditions affect the chemical transformations that occur during decomposition. The release of hazardous chemicals during decomposition is influenced by factors such as temperature, rainfall, humidity, and seasonal variations. For instance, higher temperatures and humidity accelerate the release of nitrogen and potassium during the decomposition process. Furthermore, the presence of certain compounds in the litter, such as phytotoxic compounds, can inhibit microbial growth and impact the chemical transformations that occur.

The decomposition of litter also affects the carbon cycle and releases carbon dioxide (CO2) into the atmosphere. Microorganisms involved in the decomposition process release CO2 as they break down carbon-rich litter to maintain their C:nutrient ratio. This contributes to the greenhouse effect and climate change.

Moreover, litter decomposition impacts the nutrient cycle and the availability of nutrients for plants. As litter decomposes, it releases nutrients such as nitrogen, phosphorus, and potassium, which can be stored in the soil for plant reuse. However, the improper disposal of certain types of litter, such as hazardous waste, can lead to the release of toxic chemicals into the environment, affecting both land and water sources.

Open burning of tyres releases hundreds of chemical compounds

The act of littering has serious consequences for the environment and communities. It contributes to air, land, and water pollution, with approximately 8 million tons of plastic waste ending up in oceans each year. Open-air burning of litter, which accounts for around 40% of the world's litter, releases toxins that cause respiratory issues and other health problems.

Open burning of tyres, in particular, is a significant source of air pollution. Tyre fires release hundreds of chemical compounds, many of which are toxic and carcinogenic. These chemicals include:

• Sulfur dioxide (SO2)
• Nitrogen oxides (NOx)
• Carbon monoxide (CO)
• Carbon dioxide (CO2)
• Volatile organic compounds (VOCs)
• Particulate matter (PM), including fine particles known as PM2.5
• Heavy metals such as lead, cadmium, mercury, and zinc
• Polycyclic aromatic hydrocarbons (PAHs), including benzene and naphthalene
• Dioxins and furans

These emissions contribute to heavy smog formation and have adverse effects on the respiratory, cardiovascular, and reproductive systems. Prolonged exposure increases the risk of respiratory diseases, including asthma, bronchitis, and even lung cancer.

The combustion of tyre-derived fuel (TDF), often used as an alternative fuel source in industrial processes, releases similar toxic emissions. While TDF can reduce the consumption of non-renewable fossil fuels, its environmental considerations cannot be ignored. The release of pollutants from tyre burning also contributes to ecosystem degradation, damaging plant life, aquatic organisms, and surrounding habitats.

Plastic waste is ingested by marine animals, ending up in the air we breathe

Plastic waste is one of the most common forms of litter, and it is a significant contributor to air pollution. When plastic waste is not disposed of properly, it often ends up in our oceans and waterways, posing a severe threat to marine life. Marine animals, from small finches to blue whales, ingest plastic or get entangled in it, leading to injury, starvation, suffocation, and death.

Plastic debris in the ocean breaks down into smaller and smaller pieces over time. These microplastics are invisible to the naked eye but are pervasive in our waterways and even the air we breathe. According to National Geographic, microplastics are present in the air and have been ingested by humans, as reported by the World Health Organization. This issue is exacerbated by the fact that plastic can take hundreds, if not thousands, of years to fully degrade.

Fish often mistake small plastic pieces for food, and molluscs like mussels and oysters inadvertently consume microplastics when filtering seawater to feed. A recent study found that all samples of mussels sourced from UK waters contained microplastic particles. This contamination moves up the food chain, affecting larger fish, marine mammals, and ultimately, human seafood eaters.

The impact of plastic ingestion on marine life is profound. Studies have shown that sea turtles that ingest just 14 pieces of plastic have an increased risk of death. Similarly, the ingestion of plastic has been linked to the deaths of up to a million seabirds annually. Young animals are particularly vulnerable as they tend to be less selective about what they eat and drift with ocean currents, increasing their exposure to plastic debris.

The problem of plastic waste in our oceans is a pressing global issue. It is estimated that up to 13 million tons of plastic waste enter the ocean each year, threatening marine ecosystems and the livelihoods of those who depend on them. With the ever-increasing production and use of plastic, it is crucial to address the irresponsible disposal of plastic waste to mitigate its devastating effects on the environment and human health.
