Decades after most countries stopped spraying DDT, frozen stores of the insecticide are now trickling out of melting Antarctic glaciers. The change means Adélie penguins have recently been exposed to the chemical, according to a new study.

The trace levels found will not harm the birds, but the presence of the chemical could be an indication that other frozen pollutants will be released because of climate change, says Heidi Geisz, a marine biologist at Virginia Institute of Marine Science in Gloucester in the US. She led a team that sampled DDT levels in the penguins.

She worries that glaciers could release an alphabet soup of chemical pollutants into the ocean, including PCBs and PBDEs – industrial chemicals that have been linked to health problems in humans.

"DDT is not the only chemical that these birds are ingesting and it is certainly not the worst," Geisz says.

1. Say goodbye, everyone

I don't think the Earth will miss us much, IMO.

2. They found nuclear fallout in glaciers in the Canadian Rockies. Probably from

Russia testing weapons in Siberia. Those glaciers hold onto all kinds of dirt. I was amazed when I went to bow glacier how messy,dirty it was. And the little ponds were filled with scum and multicolored. It was really odd.
