Agreed. As I stated, there are better options, but also as stated, given the much much larger exposure from a variety of uses beyond shipyards etc, I think it a fair question why not many many more incidents of health problems. Furthermore; and I am near certain it has been argued in other venues, could there there be other additional environmental factors. I do not know for a scientifically proven fact either way. All I'm saying is, I do not know and I doubt anyone else does either. In the mean time, take precautions, but take with a grain of salt all the hype otherwise.
