Drugs take place in the rivers where they affect the entire ecosystem


A new study reports that the number of 69 pharmaceutical compounds found in water ecosystems has been found. These substances proved to be slowly working in the food chain that affects the entire food network.

Although plastic contamination takes a lion's share of media attention, other pollution can be harmful and harmful. The trace of pharmaceutical products, for example, is around us.

"Biologically active pharmaceutical substances contribute to global surface water pollution, but their existence prevails in a water vessel," the researchers wrote in a new study.

Usually, the chemicals used, such as medicines and personal hygiene products, will end near the nearby waters where they can accumulate over time. Majority of wastewater treatment facilities are not equipped to erase the sewage and further infrastructural infrastructure.

In order to see how these substances affect the environment in which environmental ecosystem ecology ecology and co-author viewed six streams in Melbourne. They are sampled for 98 pharmaceutical compounds – the most exhaustive screening date. Pharmaceutical agents include antibiotics, antidepressants, antihistamines and nonsteroidal agents.

This is not a problem that restricts Australia or just stream, researchers emphasize. Drugs are getting ecosystems and they go to the food chain and we still do not know what the results are.

"Pharmaceutical contamination is in surface waters across the globe and there are many studies that document the document," he told ZME Science. "Drugs in the water of wastewater through the input, because many wastewater treatment plants are not designed to sewage pipes. Also, pharmaceutical supplies are from wastewater or aging infections and septic tanks. In many parts of the world, inconsistent, raw sewage discharged to surface waters. This karo all over the world. "

They saw how these substances are transferred to the food chain, especially focusing on the riparian (river) spiders. Erin Richmond, Institute of Maternity Ecology at the Australian Monastery University and the advantages of research explained:

"We've focused on riparian spiders because they are building their webs over streams and feeding adult water insects because they are the source of water."

Their analysis was found in 69 different pharmaceutical compounds of water insects and 66 compounds of riparian spiders. There was an apparent trend in the heavily populated areas with the highest level of sustainable treatment facilities and potential septic tank leaks. In this direction, concentrations are 10-100 times higher than average.

"Stream Life is a skinny mixture of pharmaceutical," says Rosi. "Our research is the first that this chronic drug contamination can affect water insects and exceeds digestive food, in some cases it is revealed by acute therapeutic doses."

Even in "clean" areas, there are still evidence of pharmaceutical pollution.

"The pharmaceutical was all insect and spider we experienced – including those collected by the Dandenong Ranges National Park," Richmond notes. "It seemed to be clearly spotted in the spot, because people live in the drainage area of ​​the park and visit the park."

The most frequently discovered contaminants were antidepressants. However, it is not clear whether this increased local consumption or if there are other property antidepressants that they appear to be higher concentration.

Unpredictable influence

Although there is a good chance that these drug contamination is important for ecosystems, the study does not analyze these effects – even though it still remains a follow-up study.

"69 different drug insects have been identified, we do not know what this trout or platope is 69 different pharmacologists during their diets, and it is noteworthy that riparian (spray) spiders also collect various kinds of drugs and, most likely, birds, bats and others Animals that may be exposed to excessive insects can detect drugs Va Studies have found that antidepressants including fish behavior can be changed, but so far as we do not know the nature of the impact of drugs, "- said Richmond.

Silver is neglected, but all of us can make a difference. Rosi and Richmond told ZME Science that we can and should be attentive to dispose of our medicines and pharmaceutical products.

"As many consumers as there are many ways we can reduce the presence of pharmaceuticals, properly dispose of unwanted medications or those who use their date of use Take the" back program "for waste disposal Please do not extend this drainage or toilet If you have a septic system, Maintain the system and ensure that it is f nktsionirebs.
