Hi Vivian - I haven't, but I did live very near to a superphosphate works that used sulphur in its production process when I was a child. I remember quite well the smell of sulphur fumes, and seeing the bright yellow powder as I walked to and from school along the railway tracks at the siding where it was offloaded nearby. Makes you wonder, eh? That, and the fact my parents were into market gardening and poultry farming with all the then fashionable herebicides/pesticides ... what hope? I'm probably lucky I only have PD! (if that IS all I have).
