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 as many as 98 percent of various types of pharmaceutical products.
Scientists have discovered 69 different types of insect medications and 66 in spiders. Scientists have explained that drugs are transmitted by a food chain. Insects feed on spiders, which are foods foreign bloody, the Guardian writes.
Drugs flow into streams through sewage treatment plants that do not remove all harmful substances that people consume. Some come through septic tanks or permeable water and sewage pipes.
Water from the stream and current around Melbourne, even from those with very little waste, contained "the whole cocktail of drugs," the researchers said, not hiding that they were unpleasantly surprised.
This is the first study in the world that suggests that there are a number of pharmaceutical substances in the food chain and that some animals can be exposed to half the daily dose of antidepressant that is prescribed for humans, said study manager Erin Richmond.
– The study has shown that many traceable drugs are retained in water bodies of invertebrates, but also in the watercourses from where they are thrown into the surrounding areas surrounding them. Spiders, birds, blind mice are consumed here. Richmond explained.
The results of a study by scientists at Monash University in Melbourne were published in the Nature Communications journal.
