SUMMARY OF THE LISTING DECISION FOR SULFUR DIOXIDE
Following a staff presentation, comments from the public and committee discussion, the DARTIC determined that sulfur dioxide has been clearly shown to cause developmental toxicity based on findings of low birth weight in scientific studies. The chemical was added to the Proposition 65 chemical list as known to cause reproductive toxicity (developmental toxicity endpoint) effective July 29, 2011. The DARTIC did not find that sulfur dioxide has been clearly shown to cause female or male reproductive toxicity.
