According to Dr. Alfred Lea at the University of Texas Medical Branch, the rotting sargassum found on beaches can emit both ammonia and hydrogen sulfide gasses, which can irritate your nose and throat, or cause breathing difficulties if you have asthma or other sensitivities. But the breezes at most beaches will naturally dilute these gasses, he said, greatly reducing the risk.
