What’s different about industrial and home use? It’s either a carcinogenic or it isn’t.
Well, #1, they didn’t call it a carcinogen, just a “probable carcinogen”, which means they don’t have definitive data.
#2 - With carcinogens, like any toxins, the magnitude of exposure matters. Some carcinogens are of the level that they are harmless to adults, but a risk to children, or harmless to those exposed only intermittently, but a risk to those who are exposed daily.
Frequency of exposure. Farmers would regularly use it at it’s greatest strength and over long periods of time and in tractor and wind conditions that prevent their escaping exposure.
