Plastic is everywhere, from plastic packaging and containers to toys and textiles. While many of the chemicals added to plastics are useful and safe, some are toxic and can have adverse effects on both human health and the environment. Chemicals of concern in plastics include phthalates, bisphenols, heavy metals, flame retardants, and more. These chemicals can act as endocrine disruptors, hormone disruptors, and are linked to a range of health issues, including reproductive disorders, asthma, cancer, infertility, and heart disease. To reduce exposure to toxic chemicals in plastics, individuals can opt for alternatives like glass and steel containers and reduce their use of single-use plastics. Additionally, stronger regulations are needed to address the health and environmental risks associated with chemicals in plastics.

What You'll Learn
Bisphenol-A (BPA)
Bisphenol-A, or BPA, is a hormone-disrupting chemical that has been linked to a wide range of health issues. It is produced in large quantities and primarily used in the production of polycarbonate plastics and epoxy resins. These resins are used to coat metal food cans, bottle tops, and water supply pipes. Polycarbonate plastics, which consist mostly of BPA, are used in products like shatterproof windows, eyewear, and water bottles.
BPA is of particular concern because human exposure is so widespread. A 2003-2004 survey by the CDC found detectable levels of BPA in 93% of urine samples from people aged six and older. Food and beverages are the primary source of exposure for most people, as BPA can leach into food from the protective internal coatings of canned foods and from consumer products like polycarbonate tableware and food storage containers. Heating food or liquids in plastic can also allow plastic chemicals to leach faster.
Several jurisdictions have taken steps to reduce exposure to BPA, particularly for infants and children, who may be the most vulnerable to its effects. The FDA banned the use of BPA in baby bottles and children's sippy cups in 2012, and some studies indicate that BPA exposure in infants has decreased as a result. BPA-free plastics have been introduced, but there is controversy over whether the alternative bisphenols used are actually safer.
To reduce exposure to BPA, individuals can opt for stainless steel or glass containers instead of plastic, avoid plastic with the recycle symbol #3 (PVC), and try not to heat food or liquids in plastic containers.

Phthalates
Due to health concerns, lower-molecular-weight phthalates are being replaced by higher-molecular-weight phthalates and non-phthalic plasticizers in the United States, Canada, and the European Union. Several countries have established restrictions and regulations on certain types of phthalates, and the FDA has revoked the authorization for the use of 23 out of 28 phthalates in food contact applications.
To reduce exposure to phthalates, it is recommended to use glass or steel containers instead of plastic, avoid heating food in plastic containers, and avoid fragrances that may contain phthalates. It is also important to read labels and look for food products stored in glass rather than plastic.

Polyvinyl chloride (PVC)
Polyvinyl chloride, or PVC, is a type of plastic that is widely known as one of the most toxic plastics for both health and the environment. It is a mass-market plastic used in industry and households and is found in many consumer products, including plastic bottles, toys, school supplies, upholstery, shower curtains, and food packaging.
The production, use, and disposal of PVC raise concerns for human health and the environment due to the release of several toxic chemicals. During its manufacturing, PVC releases dioxins, phthalates, vinyl chloride, ethylene dichloride, lead, cadmium, and other toxic chemicals. Phthalates, in particular, are plastic softeners that are not tightly bound to other molecules in the plastic, allowing them to migrate and find their way into our bodies. They are endocrine disruptors linked to various health issues, including reproductive malformations in baby boys, reduced fertility, developmental disorders, asthma, and increased allergic reactions.
The ageing of PVC, especially due to UV radiation, further contributes to its environmental impact. PVC is highly sensitive to UV radiation, and its degradation leads to the formation of microplastics, which accumulate in the environment and living organisms, becoming part of the food chain. These microplastics are commonly found in drinking and bottled water, leading to human exposure to their harmful effects.
To minimize the risks associated with PVC, it is recommended to avoid products made from this material. Consumers can opt for alternatives such as stainless steel or glass bottles, non-plastic toys, and glass or ceramic containers for food storage. It is also advisable to avoid heating food in plastic containers, as high temperatures can accelerate the leaching of chemicals from PVC into the food.
While PVC has advantages such as durability and low weight, its negative impact on health and the environment cannot be overlooked. Regulatory actions and stronger laws are necessary to limit the use of hazardous chemicals in plastics and protect human health and ecosystems from the harmful effects of PVC and other toxic plastics.

Polystyrene
To avoid exposure to polystyrene, people are encouraged to use alternatives such as reusable plates, cups, and utensils instead of disposable polystyrene products. Many schools and cities are banning polystyrene products, and retailers are offering alternatives. It is recommended to avoid polystyrene cups and containers, often labelled with the number 6 inside chasing arrows. When getting food to-go, one can ask for non-polystyrene options and encourage restaurants to use reusable containers.

Brominated flame retardants
There are five main classes of BFRs, each with varying uses:
- Hexabromocyclododecanes (HBCDDs): Used for thermal insulation in the building industry.
- Polybrominated diphenyl ethers (PBDEs): Found in plastics, textiles, electronic castings, and circuitry.
- Tetrabromobisphenol A (TBBPA) and other phenols: Used in printed circuit boards, thermoplastics (mainly in TVs), and polybrominated biphenyls (PBBs).
- Polybrominated biphenyl (PBB): Found in consumer appliances, textiles, and plastic foams.
- Other brominated flame retardants: Marketed under different commercial brands.
While governments have generally determined that BFRs are not harmful to human health at typical exposure levels, there are ongoing scientific assessments of the risks associated with specific BFR compounds, such as hexabromocyclododecanes (HBCDDs) and polybrominated diphenyl ethers (PBDEs). Some BFRs, like PBDEs, have been restricted or banned in the European Union due to potential health concerns.
To reduce exposure to BFRs and other potentially harmful chemicals in plastics, individuals can opt for alternatives such as glass and stainless-steel containers for storing and heating food. Avoiding plastics with certain recycling codes, such as codes 3 and 6, can also help minimize contact with toxic chemicals like phthalates and styrene.

Frequently asked questions
Some of the most common harmful chemicals found in plastics include phthalates, Bisphenol-A (BPA), polyvinyl chloride (PVC), brominated flame retardants, and styrene. These chemicals have been linked to various health issues, including endocrine disruption, reproductive problems, asthma, cancer, and organ damage.
These chemicals are not tightly bound to the plastic molecules and can migrate, making their way into our bodies through ingestion or inhalation. They can also be released into the environment during the production, use, and disposal of plastic items. The effects of exposure to these chemicals can vary, with some causing immediate health issues, while others may have long-lasting or delayed impacts.
To avoid exposure, look for alternatives to plastic such as glass, stainless steel, or ceramic containers for storing food and drinks. Avoid plastics with recycling codes 3, 6, and 7, as they may contain harmful chemicals like phthalates, styrene, or bisphenols. Be cautious when heating food in plastic, as high temperatures can cause plastics to release chemicals faster. Check with manufacturers or retailers to inquire about specific products and their chemical content.
