What the press release does not say is that these levels are well below the safety standard. The math is very simple, but the Environmental Working Group apparently couldn't work it out. In 8 hours, the standard is 630 ppb and in 1 hour it would be 5000 ppb. It is continuous exposure levels that are significant, and they are within safety margins. It is difficult to comment further on the work of the EWG, since they have not seen fit to share it with regulatory authorities.
Most scientists are eager to have their work peer-reviewed by other scientists.
This is a publicity stunt, not science. The press release also grossly misinterprets the intent of legislation now under consideration. The role of the state Air Resources Board, the Department of Health Services and other agencies remains the same under the proposed legislation, which is scheduled for a vote today. It cannot be coincidental that the press release was also put out today. The Department of Pesticide Regulation, working with the state Air Resources Board, has conducted extensive monitoring around methyl bromide application sites.
