For what it’s worth, PT lumber has been arsenic-free, in the US at least, for almost 20 years now

- war1025 6y agoDoes anyone happen to know how toxic the new copper compounds are? Obviously they are toxic enough to microbes to make the wood rot resistant. Also a fun fact I learned since our deck was originally built 15-20 years ago shortly after the switch-over to the new treated wood: They needed to re-formulate the coatings they put on fasteners to hold up decent in the new treated wood. It took them a couple years to figure that out or at least for the knowledge to be widely known. All the screws in our deck that I took out were corroded to the point that many of them looked more like toothpicks than screws when I removed them.
