Scientists studying ice cores from Greenland have discovered a 2000-year-old layer of lead. This layer was produced by air pollution from extensive mining activities in ancient Spain.

The Spanish lead mines were operated by the Romans and Carthaginians, who were not aware of the dangers posed by lead. The mining, combined with the widespread use of lead in pipes, bowls, and utensils, is believed to have caused significant lead poisoning among the ancient Romans. Some speculate that it may even have contributed to the downfall of the Roman Empire.
