Going through the full article and study it would be interesting for each of you who have a scale at your disposal to measure out 700mg of a substance and see what volume the study is talking about that was administered daily. Granted it did not cause a problem at 22 weeks, only did it start to cause problems at 58 weeks.Originally Posted by Annie
How many remember the scare about sacchrine (sweetner) and it causing cancer? the study was done similary to this. In that study (sacchrine) mice were fed massive unreasonable doses daily. It took from a year to 2 years and each rat did develop cancer. What was the dose they gave the rats? It was the equivelent of giving each rat 1000 cans a day of artificially sweetened soda. No one is going to ingest that much let alone a rat.
Yes there is a risk for workers in in an environment where they are massively exposed on a continual basis day in and day out with no precautions at all. When that study is viewed as to what the protocals were for exposure it becomes ludicrous. We as photographers are not going to be swimming daily for long extened periods (10 or more contstant hours) to pyrogallol. The study also avoided saying what form they used to test with. Only the oinments administered were cited, and those did not until covering the enitre rat cause a problem. It senstized, or caused a rash after nearly a year. in conclusion, wear gloves if you are going to have your hands submersed for hours on end each day.
