THE PRODUCTION OF WOOD PRESERVATIVES AND THE REGISTRATION OF IMPREGNATION PLANTS IN THE FORMER GDR

In order to record the production of wood preservatives and the locati on of impregnation plants in the former GDR, documents of the Office f or Standardisation, Measuring Affairs, and Products Testing (Amt fur S tandardisierung, Messwesen und Warenprufung, ASMW) were evaluated. Dur ing the period of 1970-1988 annually app. 15.000 t of wood preservativ es were produced, thereof 1/3 water soluble salts and 2/3 oilbased pro ducts. The records revealed that environmentally relevant substances s uch as arsenate and pentachlorophenol (PCP) were used in the former GD R. The present situation of impregnation plants involves special probl ems, as the majority of the recorded vacuum pressure-and dipping devic es showed a desolate condition since in the time of GDR. Corresponding investigations at the different locations will show to what extent re medial measures are necessary.
