Study Reveals That Plastic Food Packaging Can Release Up To 9,936 Chemicals, Highly Linked To Hormonal Disruptions, Cardiovascular Diseases, And Cellular Changes.
Plastics used as food packaging may conceal a threat that goes far beyond what is visible.
Researchers have identified up to 9,936 chemicals present in these materials. And the most concerning part: many of them migrate to food and consequently to the human body.
A Risk Present in Daily Life
The plastic packaging used to store or heat food contains compounds that, over time or under certain conditions, detach from the material.

Home-built airplane by a Minas Gerais engineer uses car parts, such as a power window motor for the flaps and a tachometer on the dashboard. The project took six years, and the aircraft has autonomy to fly up to seven hours non-stop.

It seems like science fiction, but it already exists: a Swedish electric boat uses a car battery, carbon fiber hull, and smart hydrofoils to fly over the water and travel 105 km in almost total silence.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.
Heat, the fat from food, sunlight, and the use of microwaves accelerate this migration process.
This means that heating a lunchbox in the microwave or leaving a wrapped snack in the car can intensify contamination.
The composition of plastics goes beyond basic polymers. Colorants, plasticizers, stabilizers, and other additives are added.
Moreover, the manufacturing process may leave residues and impurities that also become part of the final material.
The problem is that many of these elements are not chemically bound to the plastic in a stable way, which facilitates their release.
Proven Effects on Human Cells
Scientists from the Norwegian University of Science and Technology analyzed 36 plastic products commonly used in countries such as the United States, the United Kingdom, South Korea, Germany, and Norway. Using an advanced technique called high-resolution mass spectrometry, they identified thousands of substances in the materials.
Tests demonstrated that many of these compounds affect hormonal functioning and cellular metabolism.
Changes in the activity of G protein-coupled receptors, which perform essential functions in the body such as growth, reproduction, and energy use by cells, were also observed.
These findings confirm other population studies that have already detected the presence of BPA and phthalates — two of the most well-known compounds — in over 90% of the tested individuals in Europe, North America, and Asia.
Serious Consequences for Health
Ongoing exposure to phthalates has been associated with around 350,000 deaths from cardiovascular diseases in 2018, primarily among middle-aged adults.
Additionally, these substances are linked to obesity, diabetes, and hypertension.
The alert goes beyond the already known bisphenol A. Products labeled “BPA-free” often use substitutes like bisphenol S (BPS) and bisphenol F (BPF), which have also shown to cause similar cellular damage.
Solution Lies in Redesigning Plastics
Given the complexity and number of substances involved — over 13,000 already known — experts assert that it is not feasible to evaluate each compound individually.
The proposal, therefore, is to redesign plastics from their origin to make them safe for health and the environment.
Researchers and companies are already testing new solutions, such as biodegradable polymers made from plants. These materials block the entry of oxygen and moisture, helping to preserve food while avoiding chemical contamination.
International Mobilization and Ongoing Legislation
A global treaty to combat plastic pollution is under discussion among 175 countries, with formalization expected by 2026.
The goal is to tackle the problem at its source by establishing standards and limits for the use of harmful substances.
While the agreement is not yet in force, some actions are already being taken. The European Chemicals Agency has classified several plasticizers as substances of very high concern.
In the United States, several states prohibit the use of BPA in materials that come into contact with food. Companies are also starting to create open registries of additives to prepare for future requirements.
What Each Person Can Do
While structural changes take time, experts point out that there are simple measures that can reduce exposure to dangerous compounds:
- Avoid heating food in plastic packaging. Prefer glass or ceramic containers.
- Favor fresh or frozen foods instead of canned or ultra-processed items.
- Replace scratched pots and utensils, especially those with non-stick coatings.
- Ventilate spaces with new plastics, like cars and furniture.
These small actions can make a difference, as exposure to chemical compounds is cumulative. Each meal packaged in plastic or drink consumed from a plastic bottle increases contact with these substances.
Path to a Circular Economy
Investment in compostable bioplastics — produced from sources such as corn starch, cellulose, or algae — has the potential to eliminate various toxic chemicals and reduce the persistence of waste in the environment.
Additionally, the application of so-called green chemistry allows the creation of materials that degrade in a few weeks and do not release pollutants during the process.
Replacing traditional plastics with these new technologies could drastically reduce environmental impact and health risks.
But for this to happen on a large scale, it will be necessary to expand industrial production, promote strong public policies, and raise public awareness about the hidden dangers in everyday packaging.
