Science in the fight against Amazon deforestation. This is what research by Ufam, the Federal University of Amazonas, in conjunction with the Federal Police, wants to demonstrate in Brazil. "Stable isotopes is the analysis we do to verify the chemical signature of these trees in order to verify the origin of the wood. After assembling this database, when there is a seizure we can confirm that the wood was taken from the area specified in the document. We can go to that area to make a comparison to check if the wood is compatible with what was seized," said federal criminal expert Aroldo Oliveira.
