In Germany, you will find all-around three million structures that happen to be contaminated Using the harmful wood preservatives lindane and pentachlorophenol (PCP).

Carol Clausen, a study microbiologist at FPL, has actually been dealing with microbes to biodegrade CCA-treated Wooden. After grinding up CCA-treated wood, she has obtained as many as ninety two% removal of copper and 42% removal of arsenic, though the chromium is website bonded incredibly tightly towards the wood lignins, and she or he has to date been unsuccessful in taking away it.
