Summary
DescriptionPiquetPesticides detail 02.jpg |
Français : Les Traitements conservateurs des bois. (ici à base de cuivre principalement) ont une efficacité limité. Ce piquet de bois a fini par se dégrader dans le sol, après quelques années de lessivage du pesticide par les pluies et par l'eau du sol, et peut-être en raison de processus d'adaptation (par sélection naturelle) des bactéries et champignons xylophages.
Certains produits ont une efficacité plus durable (créosote par exemple), mais présentent une forte toxicité et génèrent des risques plus graves pour l'homme et l'environnement et une moindre recyclabilité des bois anciens.. Dans ce type de cas, le cuivre, chrome et/ou arsenic utilisés comme pesticides (insecticide et fongicide) ont contaminé l'environnement et le réseau trophique. English: Wood preservation Treatment of wood (here mainly copper) have a limited effectiveness. This wooden stake eventually degrade in the soil after a few years of pesticide leaching by rain, and perhaps because of the adaptation process (natural selection) of bacteria and fungi boring. Some products have a longer lasting effectiveness (eg creosote), but have a high toxicity and generate greater risks for humans and the environment and less recycling old wood. |
