What happens to the chlorine stripped off the TCE? Is it converted into insoluble inorganic compounds or is it available to react with another aquifer...
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...
