Digital Photography Reduces Pollution

Published fredag 25 november 2005 kl 11.00

Experts here say the growing use of digital photography has helped clean Stockholm’s water, by reducing emissions of silver from photo labs into sewage systems.

Tests have shown that silver levels in the Stockholm archipelago have dropped by more than half in five years.

Ragnar Lagerkvist of the Stockholm Water authority says he is convinced this is primarily thanks to digital photo technology. He says most of the silver emissions come from photo labs, as well as X-ray plates from dentists and hospitals.

The Swedish Environment Board says that silver can be more toxic to water organisms than mercury. According to reports at least 90 percent of all cameras sold in Sweden today are digital.
