 Big leaf maple, again, the dust, bronchial asthma, dermatitis, rhinitis, that's a big one. Soft maple may affect lung function, and that is the dust. Same with hard maple. So a hard rock maple, be very careful. Some of the ones here that there's a lot of different ones here on my list that I'm working down, you know, like a Rhodesian teak, respiratory inflammation, irritation. Now, common one, yellow birch, dermatitis, respiratory problems.
