Ice core records uncover widespread air pollution from early 20th-century copper production

Headline from Phys

About a century ago, the Anaconda Copper Mine complex near Butte, Montana, was emitting vast amounts of air pollution into the atmosphere. As small particles of arsenic and other heavy metals were carried by winds over the Arctic, storms eventually helped pull them to the ground, where they joined l…
