    Natural or Synthetic? Test reveals origin of chemicals in blubber

    Natural compounds akin to synthetic flame retardants wend their way up marine food chains and accumulate in whale blubber, researchers have found. It's the first time that scientists have used a new radiocarbon-dating method to determine whether potentially troublesome chemicals in the environment are of natural or synthetic origin.

    The oceans contain thousands of naturally occurring...
