Everyone is discussing plastic pollution, but no one is discussing the impact on public health due to single-use plastics. Single-use plastics such as plastic bags, straws, food packaging, and cutlery have the potential to create a myriad of health issues at the individual as well as the societal level. The following article will discuss the impact of single-use plastics on public health in simple terms and examples.

1. Leaching chemicals in food and beverages

Impact: Single-use plastics emit toxic chemicals such as bisphenol A (BPA) and phthalates when they are heated or come into contact with acidic products, and they can seep into food and beverages. The chemicals have been linked to a number of diseases, primarily hormonal disorders that lead to hormone imbalance.

Example: Environmental Health Perspectives research found that BPA can migrate from plastic forks into foods and beverages. BPA exposure in animal and laboratory studies has been associated with reproductive issues, fetal development issues, and increased risks of certain cancers. For instance, a 2016 study discovered that women with greater amounts of BPA in their urine experienced more miscarriages.

2. Air Pollution from Burning Waste

Impact: Single-use plastics emit toxic chemicals when they are combusted, such as dioxins, furans, and heavy metals. These contaminants can be dangerous to air quality and trigger serious respiratory and cardiovascular issues.

Example: Where plastic waste is improperly disposed in regions such as Southeast Asia and Africa, plastic waste is often incinerated. The WHO has also indicated that exposure to dioxins has led to shortness of breath, immunosuppressant, and skin diseases. Second, individuals residing in the vicinity of incinerators also get asthma and other chronic respiratory disorders.

3. Microplastics in the Food Chain

Impact: Plastics degrade and form microplastics. They are small fragments that end up in the food chain. The fragments are consumed by marine animals, and they make humans ill if they consume infected seafood.

Example: University of California, Davis, studies discovered that microplastic fragments occur in nearly all seafood, such as fish and shellfish. A study in Environmental Science & Technology reported that more than 90% of salt samples from everywhere in the world contained microplastic fragments. The long-term health impacts of eating microplastics are still under investigation, but early findings indicate that they can lead to stomach issues, inflammation, and other illnesses.

4. Contamination of Drinking Water

Impact: Single-use plastics contaminate underground and surface water sources. Microplastics have been detected in tap water, bottled water, and rainwater, which has raised concerns about safe drinking water.

Example: A study by the Journal of Environmental Science and Technology revealed that nearly 83% of tap water samples from everywhere in the world contained microplastics. Citizens of Paris and other large cities discovered microplastic fibers in drinking water, which created concerns regarding the impact of the minute particles on human health. They could result in severe health issues if subjected to them for a prolonged period, since microplastics could have toxic chemicals or bacteria.

5. Public Health and Other Waste Concerns

Impact: Single-use plastics are causing environmental pollution. Such pollution has the potential to become a breeding ground for disease-carrying pests. Plastic waste is disposed of in a way that may harbor rats and mosquitoes, which are capable of transmitting diseases to human beings.

Example: In urban slum locations in nations such as India and Brazil, treatment plants for waste are not always sufficient to deal with all the trash. Plastic trash, therefore, finds its way into puddles of water, and these make perfect breeding grounds for mosquitoes. This has been linked with increased insect-disease cases, such as Zika virus and dengue fever. Dengue has increased tremendously, as reported by the WHO, and improper disposal of waste makes things worse.

6. Allergies and Sensitivities

 Impact: The chemicals used to produce disposable plastics may cause sensitivity and allergic reactions in some people. They may result in skin irritation and serious breathing problems.

Example: According to the Journal of Allergy and Clinical Immunology, studies indicated that certain chemicals found in plastics, known as phthalates, were responsible for allergic reactions and aggravated asthma. As an example, children exposed to phthalates had increased rates of asthma and allergies, illustrating the impact of plastic exposure on health.

7. Mental Health Implications

Impact: It can adversely affect mental health to live in an environment with a lot of plastic waste. Being aware of the harm inflicted on the environment and plastic pollution makes individuals feel powerless and anxious.

Example: A study conducted by the Ecological Society of America revealed that individuals who resided in regions with significant plastic Pollution reported higher levels of stress and anxiety concerning the environment. The psychological impact of witnessing natural scenery degrade can lead to widespread eco-anxiety, impacting overall well-being.

8. Economic Burden on Healthcare Systems

Impact: Single-use plastics can cause health issues, resulting in increased healthcare expenditure. Treating diseases from plastic exposure or pollution-related diseases imposes a significant burden on health systems.

Example: The WHO has argued that air pollution, exacerbated by plastic and other waste burning, results in millions of premature deaths each year. It is expensive to treat respiratory conditions, cancers, and other diseases caused by plastic Pollution, with billions of dollars incurred annually in healthcare. One estimate placed the amount that can be saved through better air quality at a maximum of $150 billion annually in the U.S.

9. Impact on Vulnerable Populations

Impact: Single-use plastics expose poor children and families to added health threats. These individuals do not usually have access to clean water, proper nutrition, and health care.

Example: The most susceptible to the ill effects of chemicals in plastics are children. The American Academy of Pediatrics found in a study that children exposed to more BPA developed behavior disorders and developmental delays. The most vulnerable to toxic chemicals are low-income families, who may be relying on inexpensive, plastic-packaged foods.

10. Loss of Biodiversity and Its Health Implications

Impact: The use of excessive single-use plastics damages animal habitats and decreases diversity among living things, indirectly impacting human health. The elimination of various species can disrupt ecosystems and allow new diseases to emerge.

Example: Loss of pollinators, like bees, through habitat destruction and plastic Pollution can undermine food security. In a study by Nature, the loss of pollinators would translate to lower crop yields, affecting nutrition and overall well-being for populations that rely on them. Loss of biodiversity also impacts the resilience of ecosystems, with communities struggling to adapt to change.
