Chemical levels vary widely among Swedish youth

Chemicals are found in products such as makeup and skincare.

Levels of chemicals in Swedish youth vary widely, according to a doctoral thesis from the Swedish University of Agricultural Sciences (SLU). Factors such as gender, place of birth and place of residence have a major impact on levels.

Chemicals are becoming increasingly common in our environment and accumulate in the human body through constant exposure. Despite their ubiquity, knowledge of their health effects is still limited.

In his doctoral thesis, Sebastian Pineda investigated chemical levels in Swedish adolescents, their exposure to these substances and potential health risks. The samples were collected via the Swedish National Food Agency's project Riksmaten Ungdom.

Pineda's research focused on long-lived chemicals that can stay in the body for years, including harmful metals and organic pollutants such as chlorinated, brominated or fluorinated substances, such as PFAS chemicals. He also studied short-lived chemicals that leave the body quickly but are found in everyday products such as makeup, skincare and plastics.

Country of birth can influence

The results show that Swedish adolescents are exposed to a "chemical cocktail" similar to that observed in other highly industrialized countries, such as the United States. However, factors such as gender and place of birth play a crucial role in the levels of different substances.

Young people born in Sweden or other industrialized countries had higher levels of persistent chemicals compared to young people born in developing countries.

– More surprisingly, country of birth also had a clear impact on levels of substances that are excreted from the body quite quickly. However, in our data, there is no information on possible sources of exposure that could help us explain this, said Pineda in a press release.

At the same time, some exceptions were noted, such as a breakdown product of DDT and a component of lindane two insecticides banned in Sweden. Young people born in developing countries had significantly higher levels of these substances compared to Swedish adolescents.

Different for girls and boys

The study revealed clear gender differences. For example, boys had higher levels of chromium, mercury and lead than girls. One possible explanation is that boys generally eat larger amounts of food and thus ingest more metals. Another explanation could be that older girls lose some chemicals through menstrual blood.

Girls generally had higher levels of chemicals found in makeup and skincare products, as well as higher levels of cadmium. In addition, the results showed that exposure to certain substances differs between northern and southern Sweden.

– Levels of these flame retardants and plastic chemicals were higher in young people in the north. We suspect that this is related to living conditions, as we know that the indoor environment is an important pathway for these substances, says Sebastian Pineda.

Chemical mixtures and the immune system

Pineda and his colleagues also investigated the potential impact of chemical mixtures on the immune system of adolescents in the context of vaccination. The study analyzed the link between exposure and antibody levels in the blood after vaccination against diphtheria, tetanus, pertussis (DTP), and measles and rubella (MR). However, the associations were considered weak and uncertain.

– The mixture exposures did not seem to be high enough to have a clear impact on the levels of antibodies against DTP and MMR, but my thesis is only a first investigation of possible chemical mixture effects on the complex immune system in adolescents, says Pineda.

Residents in vulnerable areas most supportive of Sweden’s new return grant

Population replacement in the West

Published November 17, 2025 – By Editorial staff
After the Swedish government, together with the Sweden Democrats party, significantly raised the cap for return migration grants, support for receiving the grant is now increasing among certain immigrant groups.

The Swedish government's significant increase of the return migration grant at the turn of the year is meeting mixed reactions among the population. A new opinion poll shows that support is strongest among foreign-born residents in so-called vulnerable areas – and weakest among left-wing voters.

At the same time, debate is growing about how the grant should be used and what effects it may have for municipalities and the state.

When the Tidö government (Sweden's center-right coalition government) raises the return migration grant from approximately €900 to €31,000 at the turn of the year, the goal is to encourage more migrants who are deemed difficult to integrate to voluntarily return to their countries of origin.

The reform has created extensive political debate, not least after several red-green (left-wing) municipalities indicated their opposition to the measure.

This has led representatives from the Tidö parties and the Sweden Democrats to question whether state support should continue to municipalities that do not participate in the program.

Now a new survey from Indikator Opinion, commissioned by the Järvaveckan Foundation, shows that support for the significantly increased grant varies greatly between different groups.

Support varies greatly

According to the survey, attitudes are significantly more positive among foreign-born residents living in vulnerable areas than in the rest of the country.

In these areas, 39 percent say they are positive about an increased return migration grant, while 30 percent are negative. In the rest of the country – including both native Swedes and immigrants – the proportion of positive responses is 27 percent and the proportion of negative responses is 38 percent.

The most positive group is migrants who have lived in Sweden for less than five years and who also live in vulnerable areas. There, 46 percent say they view the grant increase positively.

Ahmed Abdirahman, CEO of the Järvaveckan Foundation, believes the reaction says something important about how people experience their situation in Sweden.

That support for an increased return migration grant is greater among foreign-born residents in vulnerable areas may seem surprising at first glance. But the results show how complex the question of integration is. I see it as a sign that we need to talk more about opportunities, not just about benefits. When people don't feel included in nation-building, the willingness to consider other alternatives also increases, he says.

Right-wing voters more positive

The survey also shows large differences between different party sympathies. Among Sweden Democrats' voters, 47 percent are positive about the grant increase, while the corresponding proportion among Christian Democrats' voters is 45 percent.

The least support is found among Left Party and Green Party sympathizers, where a majority view the government's direction negatively.

Per Oleskog Tryggvason, opinion director at Indikator Opinion, emphasizes that the proposal is still unpopular among broader segments of voters.

A significantly increased return migration grant is a relatively unpopular proposal among Swedish voters – clearly more people think it's bad than think it's good. Even though the proposal is significantly more popular among the Tidö parties' voters, there is a considerable proportion of right-wing voters who are skeptical. Based on these figures, it doesn't appear to be an election-winning proposal, he says.

The grant increase takes effect at the turn of the year. How many people will actually choose to apply remains to be seen – interest has been lukewarm so far, but the government hopes the new amount will change the situation.

Swedish Public Health Agency wants to classify red fly agaric as narcotics

Published November 14, 2025 – By Editorial staff

Products containing muscimol from fly agaric mushrooms have become increasingly popular and are often sold as natural medicine. Now the Swedish Public Health Agency (Folkhälsomyndigheten) wants the government to stop the trade by classifying the substance as narcotics.

The fly agaric has long been regarded as a symbol of poisonous mushrooms, but it is not quite as toxic as the destroying angel (Amanita virosa) – which is deadly. Historically, the fly agaric is said to have been used by Siberian shamans, among others, to alter their state of consciousness in order to establish contact with the spirit world in rituals.

In Sweden during the 1800s, people hardly ate any mushrooms at all, but the fly agaric was still considered useful as it was used as an insecticide against flies, from which it also got its name. When food became scarce for Swedes, authorities tried to encourage more mushroom consumption, which briefly led to a group of mushroom enthusiasts claiming that the fly agaric was edible, something that Populär Historia has written about. During the 1970s, the mushroom began to acquire its bad reputation after new knowledge about mushroom species began to take shape.

Poses a risk

Muscimol is a psychoactive substance that can produce sedative and hallucinogenic effects, and today the substance is often promoted by so-called alternative health groups as a remedy for sleep disorders, among other things. So-called retreats are even organized where participants ingest the mushroom in ceremonial settings.

Now the Swedish Public Health Agency wants to classify the substance as narcotics. According to the agency, the substance is currently available for purchase as candy and in e-cigarettes through various online stores, and they emphasize that the mushroom is poisonous and that people are exposing themselves to risk. In addition to relatively common symptoms such as headaches, dizziness, nausea, and hallucinations, there are reports of people falling into comas after taking the preparation.

It has properties that pose a danger to people's lives and health and which can be assumed to be used for the purpose of achieving intoxication, said Adli Assali, head of unit at the Swedish Public Health Agency, to P3 Nyheter.

The US Food and Drug Administration (FDA) banned trade in muscimol at the end of last year. This summer, the Swedish Public Health Agency initiated its own investigation following a request from the Swedish Customs Service (Tullverket), which had seized the substance at border controls. The Swedish government will now decide whether the substance should be classified as narcotics in Sweden.

Swedish Prison Service opposes plan to lower criminal age to 13

Published November 12, 2025 – By Editorial staff

The Swedish government's proposal to lower the age of criminal responsibility to 13 is facing strong criticism. In its consultation response, the Swedish Prison and Probation Service (Kriminalvården) states that it is not equipped to receive such young children in prison and that they should be cared for in other ways.

By July 1 next year, the Swedish Prison and Probation Service is expected to have built prison units for children where both 15–17-year-olds and 13–14-year-olds convicted of serious crimes will serve sentences. At the same time, places at the special youth homes (SiS homes, state-run institutions for youth care) will be phased out.

In the consultation response, the Prison and Probation Service writes that imprisonment at a young age can lead to negative consequences, and that children "as young as 13 should be cared for in other ways".

These concerns become more significant the younger the children in question are, says Elisabeth Lager, acting legal director, to TT.

The Prison and Probation Service is clear that the organization does not have the required resources. It lacks both the expertise and suitable facilities to handle children as young as 13 within prisons, detention centers, or community-based sanctions such as probation. Practical issues such as education must also be addressed. At the same time, it is noted that the level of the age of criminal responsibility is ultimately a political matter.

Swedish Justice Minister Gunnar Strömmer writes that the government will "carefully analyze all consultation responses". He emphasizes that society must "care for children in a completely different way than today" in cases of the most serious crimes, both to protect victims and society, but also the children themselves.

Wireless earbuds may cause thyroid nodules

Published November 11, 2025 – By Editorial staff

Prolonged use of wireless earbuds can cause thyroid nodules, according to various studies. Furthermore, research shows that these types of earbuds expose users to varying degrees of magnetic fields.

Abnormal growths in the thyroid gland typically manifest as localized swellings in the thyroid tissue. Most thyroid nodules are benign, asymptomatic and require no treatment, but some can be malignant – something that has increased dramatically in the population over the past 15 years according to a study published earlier this year.

A study from 2024 showed that prolonged daily use of wireless earbuds that transmit 2.4 GHz Bluetooth microwaves is strongly linked to an increased risk of thyroid nodules, writes the Swedish Radiation Protection Foundation. This is explained by the fact that the thyroid gland, which is very sensitive to radiation, is one of the most exposed organs when using such earbuds as well as a mobile phone. The study also showed that sensitivity to developing thyroid nodules increased with advancing age.

"Our study highlighted a significant impact relationship between prolonged Bluetooth headset use and increased thyroid nodule risk, emphasizing the importance of considering health impacts in the use of modern technology, especially for devices like Bluetooth headsets that are frequently used daily", the researchers conclude.

Magnetic fields

Wireless earbuds emit radiation, but studies also show that they emit magnetic fields. In a study published in 2023, researchers examined six models of in-ear earbuds. These provided exposure to static magnetic fields from 20 mT at the surface to tens of μT in the inner ear. The researchers note that more research is needed on the combination of exposure to elevated magnetic fields and microwaves – recommending the use of air tube headphones.

Apple's wireless AirPods, for example, "communicate with one another using a magnetic induction field, a variable magnetic field sends through your brain to communicate with the other", explained Dr. Joel Moskowitz in the Daily Mail, who is one of the leading experts in the field of health risks from electromagnetic radiation and a member of the International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF). He noted that research on the health effects of this exposure is completely lacking.

Probably carcinogenic

Microwave radiation is something that research has shown can damage cellular DNA, cause oxidative stress and damage brain cells and function, which can have effects such as headaches, impaired memory, cognitive ability and sleep – and it is precisely this type of radiation found in wireless earbuds, something the Swedish Radiation Protection Foundation has written about.

The World Health Organization's International Agency for Research on Cancer (IARC) has classified microwave radiation as possibly carcinogenic, class 2B. Many researchers today believe that the radiation should be considered carcinogenic.
