Printer toner dumped in pond turns white swans black

White swans were stained by black printer toner while swimming in a UK pond.

(Ink cartridges contain liquid and are used by inkjet printers, while toner cartridges contain powder and are used by laser printers)

“This poor mute swan came into the centre over the weekend, contaminated from head to tail,” staff at the West Hatch Wildlife RSPCA centre wrote on Facebook.

“Staff are busy with the job of washing the substance off right now.”

The swan was attempting to clean itself in the pond in Wiltshire, before being rescued and taken to be cleaned by volunteers over the weekend.

“I was horrified because it looked like a black swan,” RSPCA Inspector Steph Daly said.

“We’re still really baffled as to what this substance is.”

We assumed it was oil but it’s more powdery, like photocopier ink toner,” Inspector Daly said.

Staff have asked for donations of dishwashing liquid to help clean the swan.

“We think it is going to take quite a lot to get it clean,” West Hatch RSPCA said.

Users on social media couldn’t believe the pictures, may thought they were black swans.
