At one time, I was a fisheries biologist for the United States Environmental Protection Agency, and retired as a fisheries biologist from the Pennsylvania Fish and Boat Commission, South Central Region.
Recently, Triclosan has come to my attention.
Triclosan is the active ingredient in antibacterial hand soap. It is hurting the environment. Triclosan kills algae, phytoplankton and beneficial bacteria in lakes and rivers and it paralyzes fish.
The Pennsylvania Fish and Boat Commission is monitoring it in the Susquehanna River and has found it in fish tissues.
That is why the Susquehanna River is so messed up. An article titled "Estogenic Compounds in Waterways" will appear in the Sept.-Oct. issue of the "Pennsylvania Angler and Boater."
Please read it, and reconsider your next purchase of hand soap and use one that is alcohol-based.
