I would not place a lot of faith in this data. It appears to be anecdotal and unscientific. For instance, sassafras causes nausea and cancer, but the incidence is "unknown"; teak causes scrotal swelling; reactions to oleander are common (have you worked with wood recently?), Port Orford cedar causes giddyness and "violent" earaches; opepe causes "blood spitting"; wenge can cause drowsyness, making it a good choice for bedroom furniture.The merchant who apparently compiled this table sells wood dust collection machinery and admits that it may not be accurate. Some would call this fear mongering.
I hope we all know that wood dust should stay out of our respiratory tracts, period, and have the common sense to know that if you introduce a new wood into your workplace and go into convulsions after slicing it up you should probably throw it in the trash heap.
