Default Potomac Male Bass Develop Eggs


http://www.msnbc.msn.com/id/6253193

Okay, I thought that the Potomac had been fairly well cleaned up. Now
we have a large percentage (79% in one check) of the male smallmouth
population producing eggs. A large part of the region's water is
supplied by the Potomac.

Default Potomac Male Bass Develop Eggs (fly)


I can't find the link now, but a similar thing was found on the
Columbia River in the Hanford Reach. I heard about it on an odd show
on NPR with a women talking about the pseudo hormones introduced in
water from polycarbonate containers. Her claim was that some complex
molecules were introduced in the 1 PPB consentration range, and they
were causing what was called a *** change in some of the Chinook (18%
IIRC). The chromosomes identified the fish as male, but they developed
eggs instead of milt.

The lady claimed that people would have troubles with the same
chemicals and we shouldn't drink water from polycarbonate bottles,
particularly if the plastic was heated anywhere near boiling. I never
managed to cross verify this one, so I forgot about it.
