Commenting on the finding, the researchers express concern that trout and other predators which feed on the bugs are being exposed to daily doses of some drugs, such as antidepressants, that are up to half of those prescribed to humans.
Published in the
scientific journal Nature Communications, the study (A
Diverse Suite of Pharmaceuticals Contaminates Stream and Riparian
Food webs) adds to growing evidence that the
pharmaceutical industry is having a dangerous impact on food chains,
water supplies, and the environment.
The drugs found included medications used in the treatment of,

The researchers stressed it is imperative to understand the risks that chronic exposure pose to predators relying on the insects and spiders as their primary source of food.
Noting that people who eat fish are also potentially affected, the study is the first of its kind to show that such a wide range of pharmaceutical drugs has infiltrated food chains.
Around the world pharmaceutical companies have been polluting the environment for decades now, with the result that even drinking water supplies have become contaminated with measurable amounts of dangerous chemical drugs.
Rarely admitted by public

A recent study (Pharmaceutical Manufacturing Facility Discharges can substantially Increase the Pharmaceutical load to U.S. Wastewaters) confirmed that water treatment plants taking discharges from pharmaceutical companies are putting high concentrations of drugs into American waterways.
While the long-term

This illustrates yet another reason why we need to replace drug-based disease-care medicine with a truly preventive system of healthcare that utilizes safe, non-toxic, science-based natural health approaches.
