Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Any other information on results incl. tables

Experimental measuring of the removal of SO2 from the air in the presence of soil.

SO2 concentration in the air is reduced from 100 to 8 ppm in 15 minutes. Autoclaving the soil prior to experiment reduced the rate of uptake to 20 pm after 15 minutes. These results indicate that the major portion of SO2 in the air is removed by some chemical reaction, however, the microbial contribution cannot be entirely excluded. It is calculated that 4x1010 of SO2 is removed every year in the United States
