Aluminum cans can be very expensive to maintain and can be dangerous to clean, according to a study published in The Journal of Toxicology and Environmental Health.
According to the study, aluminum can cause cancer and is a contributing factor to dental caries and cavities.
“The amount of aluminum in the cans, combined with the amount of carbon dioxide released by the aluminum cans, can lead to significant levels of carcinogens, including polycyclic aromatic hydrocarbons (PAHs), which are also carcinogenic,” said Dr. Svein Eriksen, the study’s senior author and a senior lecturer in chemical and biomedical engineering at the University of Copenhagen.
“The environmental costs of aluminum can be enormous.”
Eriksen and his team collected samples of aluminum cans from supermarkets in Copenhagen and the northern Danish city of Gothenburg and analyzed the amount and type of aluminum present in each sample.
In total, they tested nearly 1,400 cans from the two cities and collected more than 5,000 different types of aluminum.
Eriksens team found that cans with up to 3.8 grams of aluminum contained up to 1.2 million PAHs.
“Although this study found no evidence that aluminum cans pose a significant risk to human health, it does suggest that a more cautious approach to aluminum cans is necessary,” Eriksons study concluded.
“It would be interesting to test the effects of higher aluminum levels in other types of cans, as well as to determine if the amount or type of plastic in the packaging is a factor.”
“In general, the risks to human life associated with aluminum are very low,” Ersland said.
“Aluminum cans are not a problem for us, but they can cause problems for people, and they can be quite dangerous.
If you put a plastic bag in your car, you should be concerned about how that plastic is going to affect the air you breathe.”
Ersland and his colleagues recommended that people avoid aluminum cans and other materials in food containers, especially aluminum cans.
The Danish Association of Food Industry says that food manufacturers have to take into account the environmental effects of aluminum use in their packaging before they use it in food products.
“We are not against aluminum cans because it is a valuable ingredient, but it is an important ingredient that has to be considered when we are purchasing foods,” said Kristian Hager, an associate director at the Danish Association.
“In Denmark, aluminum is used in food packaging for example.
But it is only a small part of our food supply.
We need to reduce the amount we use and we need to understand the environmental impact of aluminum.”
The study was conducted in collaboration with scientists from Denmark, the Netherlands, Denmark, Norway and Sweden.
The study was funded by the European Union’s Horizon 2020 programme, funded by U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E).
The study is titled “Evaluation of aluminum content of a range of food packaging materials.”
