According to a recent study, a platypus living in a stream or stream with wastewater can be exposed to 50% of the human daily antidepressant dose by eating normal day beetles.
A team of scientists led by researchers at Monash University analyzed insect and river spiders for 98 different medicines in six different Melbourne streams.
In the study published in Nature Communications on Wednesday, insects were found to be 69 and 66 types of drugs were found in spiders. He claims that drugs are transferred to spiders after they have consumed insects.
Scientists then predicted what potential exposure could be for the main species fed invertebrate animals in these streams: platypus and brown trout.
Erinn Richmond, the lead author of the study, said: inn There are many studies that tell us that drugs are in water. Mı What we don't know is that these drugs are circulating in aquaculture networks?
Ilaç One thing I think is worrying about this study is that there are numbers and types of drugs detected in these insects.
”We found 69 different drugs.“
The analyzed streams had varying levels of wastewater exposure from treatment plants or other waste water sources such as leaking septic tanks or infrastructure.
The number and concentration of drug types found are the highest in insects collected with septic tanks that are leaking at the downstream of wastewater treatment plants or in densely populated areas.
However, Richmond stated that Lyrebird Creek in the Dandenong Ranges national park has insects, where even an area predicted to increase pollution is detected, with 41 different pharmaceutical components.
Drug types identified include muscle relaxants, antihistamines, paracetamol, beta-blocking agents, and small amounts of medication for Parkinson's disease.
For some classes of drugs, such as antidepressants, the researchers estimated that trout and platypus could consume half of the daily therapeutic dose for humans.
Scientists have said that drugs that produce drugs through food webs are not an issue specific to Australia and can happen anywhere where drugs are consumed.
They said that the amount of drug they detected was “undoubtedly a scorn leri because they tested only for 98 compounds and that Australia was subsidized more than 900 medicines by its pharmaceutical benefit plans. Approved by more than 1400 Food and Drug Administration in the United States.
However, Richmond said the consequences of wildlife exposure would require further investigation.
Individuals should be cautious about how to dispose of unused pharmaceuticals, and more stringent environmental rules may be necessary.
Artı As we go on, global pharmaceutical use is on the rise, “he said. Iyor There are benefits to taking medication for us, but the research clearly shows that these drugs pass through these food networks to expose beetles, spiders and potentially birds, bats, fishes and platypus. “
