The Times of India, July 28, 2017:- Commonly used antibiotics may be harming the good microbes that
are essential to a healthy environment, a study warns. When people take
antibiotics, their bodies break down and metabolise only a portion of the
drugs. The rest is excreted and enters wastewater. As wastewater treatment
plants are not designed to fully remove antibiotic or other pharmaceutical
compounds, many of those compounds reach natural systems where they can
accumulate and harm microbes in nature, researchers said.
