The story is not only interesting but presents a scientific quagmire. For instance my last exposure to this very problem shows that fish stopped producing as the absorbed compounds from women birth pills that pass out as urine. The water facilities here have so far failed to remove such substances- and many more.
And that in the western world there is unprecedented use of medical drugs from anti depression to you name it� of chemical properties are not readily understood out there this present us with fascinating science for years to come. Bwanika James, Jonathan: A similar story appeared a couple of years back concerning deformed frogs in some rivers somewhere up north. The problem is that too many chemical pollutants present in treated wastewater are being discharged into lakes and streams. Right now, we do not have standards for controlling what is being discharged into streams. The standards that are currently being used (pH, ammonia, dissolved oxygen, and suspended solids) are not adequate to screen treated wastewater for all these other chemicals. Granted we require toxicity testing but even this is not adequate to protect these sensitive organisms against all the chemicals that may be present in treated wastewater. ********************************************** Abu L.

The University of Colorado, at Boulder, was studying various streams in the area to see what kinds of species were doing what. They were surprised to find this phenomenon of male fish developing female organs and in essence trying to lay eggs. The explanation is that the water treatment plants are discharging too many female hormones(estrogens) in the water and hence the problem. They are trying to resolve this problem right now. The environment is a ver y delicate, and we ought to handle it with kid gloves.
