According to the manufacturers of pressure-treated wood with micronized copper quaternary, their lumber is safe for human consumption. However, this is not the case. Copper is a naturally occurring metal in the earth’s crust, and it can be found in a wide variety of minerals, including copper sulfate (CuSO 4 ), copper oxide (CoO 2 ), and copper nitrate (FeNO 3 ).
In fact, copper is one of the most abundant elements in nature. It is present in every living thing on the planet, from plants and animals to bacteria and fungi. The USGS estimates that the copper content of our soils ranges from 0.1 to 2.0 parts per million (ppm), depending on soil type and mineral content.
This means that, in order for copper to be leached from wood, the wood would have to have been exposed to copper for a long period of time.
