Carlsbad Residents Concerned About Cancer Risks

I need more facts before I can sign on with the "Carlsbad is a dangerous environment" movement, and this report has too few.

For example, what does Sharma mean when she says that Chase "had something like 98% mercury in his system as well as 96% titanium"? She can't possibly be describing levels of mercury and titanium in total body composition, can she?

Or does she mean the boy's blood levels of mercury and titanium were 98% and 96% higher than levels considered safe by medical authorities?

If yes, how much mercury in the blood is considered "normal" or "safe"? Such information should be included in this type of report.

According to the Oklahoma State University (reproducing info from New Jersey State Dept. of Health): "...because mercury remains in the bloodstream for only a few days after exposure, the test must be done soon after exposure. Most non-exposed people have mercury levels of 0 to 2 (all blood measurements are in micrograms of mercury per deciliter of blood, or ug/dl). Levels above 2.8 ug/dl are required to be reported to the Health Department." (

I was never good at math, but percentages don't tell me what I need to know. If you start out with a "normal" mercury level of of 0.0100 ug/dl, a 98% higher level would only be 0.0198 ug/dl, right? That's still within a "normal" range and much, much lower than the 2.8 ug/dl that requires reporting to the Health Department.

I would be devastated if one of my sons died -- my deepest sympathies go out to the Quartarone family. My heart goes out to them in their loss. But percentages don't help me understand if he had too much mercury in his bloodstream or not, or where that mercury came from.

I also need to know why the statement from Dr. Thomas Mack (the last name is misspelled in the above report) was glossed over. Is what he is saying true? That Carlsbad really is having a typical cancer occurrence rate?

That is something Sharma should investigate and report on, because that seems quite straightforward and easy to determine.
