"Although all forms of asbestos are known to cause cancer..."

Does that sound correct to you? Are there recorded cases of cancer being caused by ALL forms of asbestos? I don't think that is 100% correct. There are many forms of asbestos in serpentine rock alone and I don't believe all of those forms have been traced as the source of diagnosed cancers. What do you think?

I think this prick of an author is still trying to stop development in Placer and El Dorado Counties and is just pist because they won't give him a Pulitzer for tryin 75 times to start a panic about asbestosis because of any disturbance of the soil that has serpentine rock... California's State Rock, by the way!!!

I have seen this issue addressed during the debate on this. Letters to the editor contained the info I think. The type that is there in El Dorado county is not the cancer causing kind for the most part. That is why you do not see articles about this being a "hot spot" like you do with the tress.

It doesn't sound right to me. I took a basic geology course in college and the prof said that only some forms cause cancer, and most don't. 'Course he could have been wrong, but I remember reading the same thing somewhere else.

Perhaps all could cause cancer with sufficient exposure for their type. For example, type A could cause cancer with minimal exposure, whereas type B could cause cancer with 100 years of breathing it's condensed form from a paper bag. Maybe that's where the confusion comes from?

It's bullshit, waspman.

Western ElDorado county is serpentine country. There is a large population on which to do a study. Serpentine has been crushed and used as road and driveway gravel for years. Exposeure for humans has been for decades. This stuff is a non-issue and can be shown to be so. Do a study on real live subjects . . . bullshit!

Sand can cause cancer; fiberglass can cause cancer. Anything that leads to continuous irritation of tissue can lead to cancer. This has more to do with irritation and inflammation than with anything of an unusual chemical nature of the substance in question. Of substances that occur naturally and abundantly in the environment having relatively little or no consequence to health, different forms of asbestos are some of the more common.
