How do our phones affect our bones?

Toxic metals released during the production of technological devices from batteries, smartphones and solar panels to wind turbines can seep into human bones.

A team of scientists who studied the levels of lead contamination in the remains of 130 people buried in a cemetery in central Rome, specifically at a site that was in use for more than 12000 years, before the emergence of metal production, until the seventeenth century.

The researchers found that as worldwide lead production increased over time, so did lead absorption rates in bodies buried in the cemetery.

The researchers explained that lead is being inhaled from the atmosphere, which means that the contamination affected even those who were not involved in the production of the toxic metal.

The findings of the scientists' studies, along with the increasing demand for toxic metals such as lead for various technologies, raise widespread public health concerns.

Historically, lead production experienced high levels 2500 years ago with the minting of coins, peaking during the Roman period before declining in the Middle Ages. Then production rose again 1000 years ago, driven by silver mining in Germany, then the New World and finally to meet the demands of the Industrial Revolution. The results of previous studies indicate that lead production rates are documented in environmental archives such as lake and glacier sediments.

The findings include that those most at risk of lead poisoning are the most exposed to the toxic metal, including miners and workers in recycling facilities.

Lead can also be found in various forms of electronic devices, from batteries to the latest generation of solar panels. Hence, the waste and decomposition of these devices can release their toxicity into the atmosphere that humans breathe and the soil in which food crops are grown.

The study recommended that "any expanded use of metals should go hand in hand with strict industrial hygiene controls and ideally safe recycling of metals with increased environmental and toxicological considerations in selecting metals for industrial use."
