During the BP oil spill in 2010, responders used chemical dispersants to break up the oil. Recent studies have questioned both the safety and efficacy of those chemicals. Other studies have suggested that those concerns are overblown.

So which is it? Are dispersants dangerous? Or are they not? And why is it so hard to figure out?

This week on the Coastal News Roundup, environment reporter Tristan Baurick from Nola.com | The Times Picayune, sorts it all out with WWNO’s Travis Lux.

April 20th marked the two-year anniversary of BP’s Macondo Well explosion, which set off one of the worst oil spills in our nation’s history, causing extensive damage to marine and wildlife habitats, and to the coastal communities which depend upon them.  The full impacts of the disaster are still unfolding, but in Shell Beach, Louisiana, there are signs of how marine life is reacting to the oil and the dispersants which flooded their waters two years ago.
