Water Hazard Classification

The most important fluorocarbons have been classified for their impact on aquatic environment in Water Hazard Classes. The classification is committed according to the German “Administrative Regulation on the Classification of Substances Hazardous to Waters into Water Hazard Classes” (Verwaltungsvorschrift wassergefährdende Stoffe – VwVwS).
Three Water Hazard Classes (WGK) are defined:
  1. low hazard to waters
  2. hazard to waters
  3. severe hazard to waters

As you can see from the following table, all HCFCs and HFCs have been classified as “low hazard to waters”.
In the web site of German Federal Environmental Agency you can find more information on WGK classification.
