Vampire Steroid Reassembles at Night, Haunts US Rivers, Streams
According to scientists, the anabolic steroid trenbolone gets active at night rather than in sunlight. For this reason, it is also known as `Vampire Steroid'.
The steroid trenbolone doesn't break down in rivers and streams as thought previously, according to reports by the researchers. It is a steroid given to beef and cows on industrial-scale farms.
The US Food and Drug Administration (FDA) has approved the drug for its use in cattle feed. But it is banned for use in human beings as it is a schedule III controlled substance.
It was believed by the scientists that the compound, known to damage reproductive processes in fish, breaks down quickly in the presence of sunlight through a process called phototransformation.
But the researchers have found recently that when the sun sets and the PH level of the water is right, the steroid trenbolone gets back and reassembles itself.
According to this study, the tested amount of chemical in water may actually be higher than the samples taken by the researchers earlier.
Bryan Brooks, Director of the Environmental Health Science program at Baylor University, who did not take part in the study, said that the new findings raise important questions that need to be answered.
He said, "Reports from this paper may stimulate rethinking the timing of environmental monitoring and surveillance, for example, the vast majority of routine water quality monitoring does not examine these unregulated contaminants".
