Chemicals from burnt wood posts renew concerns

摘要

Chemically treated timber vineyard posts have been a decades-long cause of concern for many in the Australian wine industry.These posts, which use chemicals such as copper chrome arsenate (CCA) or Creosote to treat them, dry out over time and can leak potentially toxic components into the surrounding ground.During the country's summer bushfires, chemicals from burnt wooden posts were released into the air and soil, adding a further dangerous complication to those clearing and redeveloping affected blocks.
