As a biochemist i am very familiar with lots of drugs and chemical compounds such as estrogen. But i am very surprised to discover that, sewage treatment does not remove estrogen nor [the] myriad [of] other prescription drugs [excreted], which pass out of wastewater treatment plants [and back] into streams (robertson, pg. There is a vast amount of different chemicals that exist in our world, both naturally created and synthetically created. The compounds that are forgein to the natural environment, synthetic chemicals, are referred to as xenobiotics. Some can be metabolized and eventually rendered harmless by bacteria. But for many other such chemicals, which have never before existed on the planet, no organisms or natural processes have evolved which can break them down (robertson, pg.
