Minnesota Public Radio News breaks embargo on study of fresh water lake salinization
The Proceedings of the National Academy of Sciences (PNAS) lifted the embargo early Monday on a study of fresh water lakes, after a news outlet broke the embargo.
From an email that out to reporters Monday about four hours before the scheduled 3 p.m. Eastern embargo:
PNAS is lifting the embargo on the following manuscript. All other manuscripts are under the scheduled embargo of Monday, April 10, 3 pm US ET.
- Salinization of fresh water lakes
Using a dataset of long-term lake chloride concentrations from 371 freshwater lakes in North America, researchers found that lakes in the Midwest and Northeast regions that were surrounded by more than 1% of impervious land cover exhibited elevated chloride concentrations and an increased likelihood of long-term salinization, an effect likely linked to road-salt runoff, suggesting that in the future many North American lakes might be at risk of exceeding chloride concentration levels stipulated by the US Environmental Protection Agency.
