Brazilian research team uses stable isotope analysis to trace Amazon timber origins

Brazilian researchers are developing a timber traceability tool based on stable isotope analysis to help identify the origins of illegally logged wood in the Amazon region. Illegal logging is reported to be one of the major causes of deforestation in the Amazon. Local environmental and law enforcement agencies currently typically determine timber origins through plant anatomical characteristics, tree species distribution, and official records such as forest origin documents, but these methods are not always sufficient to prove that timber comes from legal areas. A research team at the Center for Nuclear Energy in Agriculture, University of São Paulo (CENA-USP) is mapping the isotopic distribution of Amazon trees. The method analyzes the ratios of different isotopes of elements such as oxygen, carbon, nitrogen, and strontium in wood cellulose to narrow down the potential harvesting areas of timber. Team leader Luiz Antonio Martinelli stated that stable isotopes are difficult to forge artificially, offering the potential to provide federal police with a more tamper-resistant technical tool.

Hungary's Paks Nuclear Power Plant Faces Full Shutdown Due to Record Low Danube Water Level

Affected by persistent drought and high temperatures, the water level of the Danube River at the Budapest section dropped to 23 cm (fixed datum reading, a record low), restricting cooling water intake at the Paks Nuclear Power Plant. Starting Wednesday, July 29, Unit 3 was the first to be shut down; the operator, MVM Paks Nuclear Power Plant Ltd, subsequently stated on its official website that all four units would inevitably be disconnected within the next 24 to 72 hours, with power generation coming to a complete halt. MVM explained that the existing water volume of the Danube is still sufficient to cool the reactors, but the intake pumps can no longer draw water because the riverbed is exposed and the pump inlets are too far from the water surface—an equipment failure rather than an absolute shortfall in cooling water volume. To this end, the Hungarian side deployed 4 pumping barges and 2 floating cranes near the plant as an emergency measure, but with water levels expected to continue falling, a preventive full shutdown remains unavoidable.
