Air ducts and insulation? SOMEONE PLEASE HELP!?

WE HAVE FLEXIBLE AIR DUCTS IN OUR ATTIC THAT HAVE BEEN OUTLAWED BY THE GOVERNMENT. THE VAPOR SHIELD HAS COMPLETELY DISINTEGRATED AND THERE ARE MAJOR HOLES IN THE DUCTS. THE FIBERGL INSULATION THAT SURROUNDS THE DUCTS IS EXPOSED AND I FEAR THAT IT IS GETTING INTO THE VENTILATION SYSTEM AND CIRCULATING THROUGH OUR HOUSE. OUR LANDLORD IS DRAGGING HIS FEET ON THE ISSUE AND HAS YET TO FIX IT. WE ARE TAKING LEGAL MEASURES AGAINST HIM BUT IN THE MEAN TIME I MUST GET ALL MY DUCTS IN A ROW. IF ANYONE KNOWS IF THE INSULATION POSES A HEALTH RISK PLEASE LET ME KNOW. I WOULD HATE TO THINK THAT HIS NEGLIGENCE HAS PUT MY CHILDREN AT RISK>
