Plastic is a material made from fossil fuels, and it is estimated that by 2050, 2 billion tonnes of chemical additives will have been used in plastic. These additives are added to improve the performance of the plastic, making it more flexible, resistant to heat, or colourful. However, some of these chemicals are toxic and can be released at any stage of plastic's life cycle, from production to disposal. These toxins can escape into the air, water, and soil, causing severe health effects such as damage to sensory organs, effects on the respiratory, nervous, and gastrointestinal systems, and increased likelihood of cancer. Additionally, microplastics can enter the human body through ingestion, inhalation, or direct contact, leading to neurobehavioral abnormalities and an increased risk of cardiovascular disease.

What You'll Learn
Plastic toxins in food and water
Plastic toxins are released at every stage of a plastic's life cycle, from the extraction of raw materials to the use of plastic products and their disposal. These toxins can contaminate the air, water, and soil, finding their way into our food and water supply.
Plastic additives, such as phthalates, PFAS, and flame retardants, can leach from food packaging, cans, and water bottles into our food. They can also escape into the indoor air of our homes and are found in microplastics. These toxins are endocrine disruptors, interfering with the production and regulation of hormones, even at very low levels. This can lead to an increased risk of health problems such as diabetes, obesity, and cardiovascular issues.
The production and disposal of plastics also release hazardous chemicals like benzene and ethylbenzene. These chemicals disproportionately affect low-income communities and communities of color. Additionally, many common building materials contain toxic chemicals, such as flame retardants in insulation and PFAS in carpets, which can harm human health.
Plastic has already entered the food chain, with animals carrying microplastics in their bodies. When these animals are consumed, the microplastics and associated toxins are also ingested, a process called "trophic transfer." Swedish scientists have shown that nanoplastics can enter the brains of fish through the food chain, leading to abnormal behavior.
The only real solution to the plastic crisis is to reduce our reliance on plastic by transitioning to safer and reusable materials. Organizations like Toxic-Free Future are working to ban toxic plastics and dangerous chemical additives, advocating for safer alternatives, and influencing policy changes to build healthier and more resilient communities.

Toxins in the air
Plastic is made from fossil fuels, and the process of extracting these raw materials releases hundreds of toxins into the air. These toxins can cause a wide range of health issues, including damage to sensory organs, the respiratory system, the nervous system, and the gastrointestinal system. They can also impair the liver and brain, increase the likelihood of cancer, and cause neurological, reproductive, and developmental issues.
The production and disposal of plastics also release hazardous chemicals, such as benzene and ethylbenzene, which can escape into the air and disproportionately affect low-income communities and communities of colour. Many common plastics, such as polystyrene, vinyl, PET, PFAS, and phthalates, contain toxic chemicals that can leach into our food, escape into indoor air, and be found in microplastics. These microplastics can then be inhaled, leading to severe health issues.
Microplastics have been found to contaminate human placentas, and breast milk has been found to be contaminated with a cocktail of plastic ingredients. This means that children are exposed to these toxins even before birth, and their development can be harmed. As they grow older, they continue to be exposed to plastics through the air, water, dust, and food.
The chemicals in plastics can act as endocrine-disrupting chemicals (EDCs), which are linked to infertility, obesity, diabetes, prostate or breast cancer, thyroid problems, and an increased risk of cardiovascular disease and stroke. They can also cause reproductive, growth, and cognitive impairments, as well as neurodevelopmental disorders. Women and children are particularly susceptible to the toxic effects of these chemicals.
To reduce exposure to these toxins in the air, individuals can take steps such as reducing plastic use, using safer materials like glass instead of plastic bottles, and advocating for better policies at the national, state, and corporate levels to ban the use of toxic plastics and their dangerous chemical additives.

Health risks
Plastic is made from a range of chemicals that are added to change and improve its performance. While many of these chemicals are useful and safe, some are toxic and can be released at various stages of plastic's life cycle, from production to disposal. These toxins can cause severe short and long-term health effects, especially for workers in plastic production and communities near production sites.
The production and disposal of plastics release hazardous chemicals such as benzene and ethylbenzene. Additionally, certain chemicals used in plastics, such as styrene in polystyrene plastics, are linked to health issues like leukemia and lymphoma. The refining and manufacturing processes can release emissions that impair the nervous system and cause reproductive and developmental problems, cancer, leukemia, and genetic impacts like low birth weight.
Furthermore, toxic plastic ingredients can leach into our food, escape into indoor air, and be found in microplastics. These act as endocrine-disrupting chemicals (EDCs), which are linked to infertility, obesity, diabetes, prostate or breast cancer, thyroid problems, and an increased risk of cardiovascular disease and stroke. Microplastics in the bloodstream can also lead to neurobehavioral abnormalities and cerebral thrombosis.
The universal exposure to toxic plastic ingredients means that even fetuses are developing in the presence of hormone-disrupting chemicals. This exposure continues after birth, as breast milk is often contaminated with plastic ingredients. Additionally, children are exposed to plastics that can harm their development, and electronics containing flame retardant chemicals can lead to cancer, lower IQ, and hormone disruption.
Communities can reduce these health risks by drastically decreasing plastic usage and transitioning to safer materials and processes. Governments and retailers have begun taking action on toxic plastics, and organizations like Toxic-Free Future are working to ban hazardous chemicals and promote safer alternatives.

Environmental impact
Plastic is made from fossil fuels, and the process of extracting these raw materials can be harmful. The infrastructure used to transport these raw materials, such as pipelines, can release hundreds of toxins, including toxins that damage sensory organs and impair the liver and brain.
The production and disposal of plastics also releases hazardous chemicals, such as benzene and ethylbenzene, which can have a disproportionate impact on low-income communities and communities of colour. Many common building materials contain toxic chemicals, such as flame retardants in insulation and PFAS in carpets, which can be harmful to human health.
Plastics are also harmful at the end of their life, particularly when they are not properly managed. They can release toxic metals, organic substances, acid gases, and other toxic substances into the air, water, and soil. Some of the toxins released by plastics are among the most toxic substances on Earth, such as dioxins and furans. These toxins can contaminate food chains through agricultural soils and terrestrial and aquatic environments.
Plastics can also release toxic chemicals throughout their use. For example, plastic additives can leach from food cans and water bottles into food, escape into indoor air, and be found in microplastics. Microplastics have been found to contaminate the human placenta, and breast milk has been contaminated with a cocktail of plastic ingredients. Exposure to plastics and chemicals can happen through ingestion of food and waste, chemicals leaching, and accumulation in air and dust. These chemicals act as endocrine-disrupting chemicals (EDCs), which are linked to infertility, obesity, diabetes, prostate or breast cancer, thyroid problems, and an increased risk of cardiovascular disease and stroke, among other issues.
To address the environmental impact of plastics, careful management of chemicals is necessary, including phasing out chemicals of concern from plastics. This can be supported by policies that prioritize ingredient transparency, assessment of chemical hazards, bans on the most hazardous chemicals, and requirements for the use of the safest options.

Toxins in electronics
Plastic is a material that is widely used in various applications, from food packaging to electronic devices. While plastic provides numerous benefits in terms of convenience and durability, it is important to recognize that it can release toxins that pose significant risks to both human health and the environment.
One of the major toxins associated with plastics is styrene, commonly found in polystyrene plastics used for food packaging and consumer goods. Styrene is a known carcinogen linked to serious health issues such as leukemia and lymphoma. The production and disposal of polystyrene plastics release hazardous chemicals like benzene and ethylbenzene, which have detrimental effects on the environment and human health, particularly in low-income communities and communities of color.
Additionally, plastics often contain toxic additives, such as vinyl, polystyrene, PET, PFAS, flame retardants, phthalates, and antimony. These additives can leach from plastic products, contaminating our food, indoor air, and water sources. They have been linked to various health issues, including hormone disruption, lower IQ, and an increased risk of cancer. The universal exposure to these toxins can impact child development, even before birth, as pregnant women are exposed to these chemicals, which then affect fetal development.
Now, turning our attention to electronics, it is important to recognize that they, too, can contain toxic substances that pose risks to human health and the environment. Many electronic devices, from TVs to tablets, contain flame retardant chemicals that are linked to cancer, lower IQ, and hormone disruption. These toxic chemicals can escape from plastic casings, polluting indoor air and exposing individuals through dust.
Furthermore, electronic waste, or e-waste, is a significant concern within the electronics industry. As technology advances and consumer demand grows, the amount of e-waste generated increases as well. E-waste operations, particularly in the informal sector, are considered one of the most hazardous occupations globally. Even in formalized e-waste recycling processes in developed countries, exposure to toxic substances is common. Mercury, for example, is used in the screens of LCD televisions, computers, and cell phones. While it is safe during normal use, if these devices end up in landfills and are cracked or damaged, mercury vapors can be released, posing a severe risk to human health and the environment.
Lead is another toxic metal commonly found in old cathode-ray tube (CRT) televisions. Lead is extremely dangerous and can adversely affect the human body regardless of whether it is inhaled, ingested, or absorbed through the skin. Brominated flame retardants are also used in electronics, and these chemicals contain bromine, which can be hazardous to humans in its liquid and vapor states, causing damage to the nervous system, liver, kidneys, and lungs.
To address the issues of toxin release from plastics and electronics, organizations like Toxic-Free Future and SAICM Knowledge are advocating for safer alternatives, pushing companies and policymakers to eliminate these harmful chemicals, and promoting environmentally sound e-waste management practices.
