The problem is trying to figure out the long-term effects associated with these chemicals. So it's always a good idea to use precautions when working with any kind of chemical, like using protective gloves or glasses, and you should never, ever burn treated wood at home. It's a good idea to find out what your wood has been treated with before using it. Exposure to arsenic can cause, among other things, nausea, diarrhea and headaches. Long-term exposure can damage organs, poison mucous membranes and affect normal heart and liver functions.
Pure arsenic is lethal.
