Antibiotics Come With ‘Environmental Side Effects’
Report published in Microchemical Journal wins Elsevier’s Atlas award
Date: July 25, 2017
Summary: Researchers are bringing attention to the fact that commonly used antibiotic drugs are making their way out into the environment, where they can harm microbes that are essential to a healthy environment.
Researchers writing in Microchemical Journal are bringing attention to the fact that commonly used antibiotic drugs are making their way out into the environment, where they can harm microbes that are essential to a healthy environment. Their review article has been selected for the Elsevier Atlas Award, which recognizes research that could significantly impact people’s lives around the world or has already done so.
“The amount of antibiotics is very, very low — there are normally nanograms per liter of these molecules found in natural environments,” said Dr. Paola Grenni, a microbial ecologist at the National Research Council’s Water Research Institute in Italy. “But the antibiotics and also other pharmaceuticals can have an effect even in low concentrations, the so-called environmental side-effects.”
When people take antibiotics, their bodies break down and metabolize only a portion of the drugs. The rest is excreted and enters wastewater. Because wastewater treatment plants aren’t 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.
That’s a big concern, Dr. Grenni said, because many microbial species found in the environment are beneficial, playing important roles in natural cycles of nutrients, primary production and climate regulation. Some microbes also degrade organic contaminants, such as pesticides. click here to continue .
