"As one class of flame retardants is phased out due to health concerns, new types – sometimes with widespread exposure and unknown effects – may be phased in. A new study examining one type of potential replacement chemicals called organophosphorous flame retardants finds that men exposed through house dust had lower thyroid hormone levels and reduced sperm concentration. This is one of the first human studies to look at potential health effects of exposure to these types of flame retardants."
