Scientists find antidepressant in the brains of sharks off the coast of Rio de Janeiro

Researchers have discovered the active ingredient in Zoloft, sertraline, in the brain tissue of hammerhead sharks near Rio de Janeiro. This finding suggests that pharmaceutical contaminants are affecting wildlife even in remote ocean areas. It raises concerns about the broader environmental impact of human medication disposal and underscores the need for more research into how such chemicals influence marine ecosystems. This discovery could prompt stricter regulations on waste management and drug disposal practices.
