The wild salmon is swimming faster due to analgesics and other drugs thrown in the rivers and the sea, reveals a new investigation.
The traces of a sleeping pill shortened the time he played so that the youth salmon would navigate through two hydroelectric dams along his regular migration route that always slows the trip, scientists say.
CLOBAZAM-A often prescribed medication levels for sleep disorders, as well as the success of river migration to the ground of youth salmon in nature, according to the findings of his son’s biggest study.
An international team of international researchers, led by the Swedish University of Agricultural Sciences, investigated how pharmaceutical pollution affects the behavior and migration of Atlantic salmon in danger of extinction.
They warned that their findings, published in the Science magazine, may seem beneficial, but any change in natural behavior and ecology of a species probably has broader negative consequences.
Dr. Marcus Michelangeli, or the Australian Institute of Rivers of the University of Griffith, emphasized the growing threat of pharmaceutical pollution to wildlife and ecosystems around the world.
He said: “Pharmaceutical pollutants are an emerging global problem, with more than 900 different substances that have now been detected in river roads around the world.
“Or private concern are psychoactive substances such as antidepressants and pain medications, which can significantly interfere with the function and behavior of the brain of wildlife.
Michelangeli said that the “real world” studies approach distinguishes it from previous research.
He said: “Most previous studies that examine the effects of pharmaceutical pollutants in wildlife have been carried out under controlled laboratory conditions, which are not dedicated to capture the complexities of natural environments.
“This study is unique because it investigates the effects of these pollutants in wildlife directly in the field, which allows us to better understand how exposure affects the behavior and migration of wildlife in a natural context.
“While the increase in the success of migration in the salmon exposed to CLOBAZAM may seem a beneficial effect, it is important to realize that any change in the natural behavior and the ecology of a species is expected to have a negative braler to both.
The researchers used innovative pharmaceutical implants of slow release and animal monitoring transmitters to monitor how exposure to clobazam and the tram of opioid analgesics affected the behavior and migration of salmon of youth salmon.
A monitoring laboratory experiment also discovered that the altered shaling behavior of CLOBAZAM, indicating that the migration changes observed in nature can be the result of drug -induced changes in social dynamics and the risk of risk taking.
But Michelangeli says that predicting the total scope of the impacts is still “challenging.”
He said: “When considering realistic exposure scenarios in which whole ecosystems are exposed, in multiple species and a diversity of pollutants, the possible consequences become equally more complex.”
While the recent decreases in the number of salmon of the Atlantic are mainly attributed to overfishing, habitat loss and fragmentation, which leads to its “endangered” state, the research team said that the findings highlight how the pharmaceutical polder could.
Michelangeli says that many pharmaceutical products persist in the environment due to bad biodegradability and insufficient wastewater treatment.
But he added: “Advanced wastewater treatment methods are becoming more effective in reducing pharmaceutical pollution, and there is a promising potential in green chemistry approaches.
“When designing medications that break down more quickly or become less harmful after use, we can significantly mitigate the environmental impact of pharmaceutical pollution in the future.”
