The answer depends on whom you ask. Old pressure treated wood contained an arsenic compound that leached into the soil. There is a new process now (MCQ treated wood) and it is believed to be safe. It uses copper with a different technology than the old method. It has been on the market for about 10 years. Are all the long-term effects known? Here is an article from Clemson Univ about using treated wood: https://hgic.clemson.edu/factsheet/treated-wood-in-the-landscape/ ^[2]
