Pressure-treated lumber has been shown to leach much less preservatives, when treated using a newly-developed technology
When people are building things such as decks or fences, they often use lumber that has been pressure-treated with preservatives. While this does indeed help the wood last longer, the chemicals will gradually leach out into the ground, harming organisms within it. Now, however, researchers have found a way of using nanotechnology to keep the preservatives in the wood.
