Interesting. I remember reading an article about pressure-treated wood in some homeowner's magazine, which said that newer pressure-treated wood was safer, but what confused me is that I went to three hardware stores, Home Depot and Lowes' which are chains, and Hechinger's, which is a local chain, and all three had only the greenish wood, and the safety fliers said they were treated with inorganic arsenic. They aren't supposed to be used in food preparation areas, and I don't know if the arsenic can leach into the garden soil, but I decided since the structure (raised tomato bed) would be temporary, not to risk it.

Maybe its "borate" rather than "barite." Boric acid and the borate ion are poisonous to ants and termites and many other insects. "Barite" should be a barium mineral, and barium salts are innocuous to human beings. Arsenic is bad news to everyone. I understand the Byrd apple orchards in Virginia are bad contaminated with arsenic in the soil (as is southern Argentina). Always wear a mask or respirator when sawing any wood treated or untreated. Woodworkers are subject to serious respiratory diseases and cancer. Be careful of your thumbs. I once knew a woodworkers who had all of his fingers and thumbs.
