When an industry grows rapidly, it often becomes a childhood disease, says Maria Albin, professor of occupational and environmental medicine at the Karolinska Institute, to P4 Halland .
The researchers examined 139 workers at 13 different companies and found elevated levels of metals such as lead, mercury and aluminum in the blood of those examined.
In many cases, workers are exposed to many different metals at once and if it affects an organ, there is a risk of a "cocktail effect," says Maria Albin.
What is needed is clearer support from authorities, the Swedish Work Environment Authority and occupational health services, the researchers say.
"I would say that the industry is not that well equipped. But having said that, I know that the industry is working a lot on it," says Karin Broberg, professor of occupational and environmental medicine at Lund University, to the radio.
