A team of scientists, led by Researchers at Monas University, analyzed insects and spiders found in six streams in this city and found traces of up to 98 percent of different types of pharmaceuticals.
Scientists have discovered 69 different types of insect and 66 spider drugs. Scientists have explained that drugs are transmitted from a food chain. Insects feed on spiders, and they are food for strange bloodshed, writes Guardian.
Drugs flow into streams through sewage treatment plants that fail to remove all harmful substances consumed by humans. Some come through septic tanks or permeable water and drainage pipes.
Water from the stream and the stream around Melbourne, even those with very little waste, contained "all the cocktail of drugs," the researchers said, not hiding that they were unpleasantly surprised.
This is the first study in the world suggesting that there are many drugs in the food chain and that some animals can be exposed to half the daily dose of antidepressant that is given to humans, said study director Erin Richmond.
– The study showed that many detectable drugs are retained in the aquatic invertebrates, but also in water streams from which they are molded in the terrestrial areas that surround them. Spiders, birds, bats are consumed here. "Richmond explained.
The results of a study by scientists at Monash University in Melbourne have been published in Nature Communications.
