is there any correlation between long term exposure to triphenyl phosphate conforming to Mil-H-19457C (+3 years daily) and tinnitus? I served aboard an aircraft carrier in the aircraft elevator pump rooms. I was exposed on a daily basis to the fluid. Shortly after leaving the navy, I developed mild tinnitus that as I age has gotten progressively worse. I am trying to figure out if this was the cause. I did at the time and still use hearing protection regularly
