When is a rock more than a rock? When it’s California’s official state rock, serpentine.
State Sen. Gloria Romero, D-Los Angeles, has introduced legislation to drop serpentine as the Golden State’s top rock. According to the California Geological Survey, naturally occurring serpentine “often” contains chrysotile, which in its fibrous form is the most common type of asbestos. Romero says California shouldn’t be heralding a rock with ties to a carcinogen.
But last week, Sacramento Bee columnist Dan Walters suggested that Romero’s bill goes a lot farther than that.
Senate Bill 624 makes a statement of finding that “serpentine contains the deadly mineral chrysotile asbestos, a known carcinogen, exposure to which increases the risk of the cancer mesothelioma.” Such a flat-out statement, Walters said, could open doors to litigation against owners of land containing serpentine, even when there’s a debate about how often chrysotile is found in serpentine.
The bill is supported by the Consumer Attorneys of California; two plaintiff’s firms: Kazan, McClain, Lyons, Greenwood & Harley and Water, Kraus & Paul; health interests, labor groups and others.
J.G. Preston, press secretary for the CAOC, called Walters’ suggestion “outrageous and wrong.” Stripping the state-rock moniker from serpentine will simply send a “symbolic message” that the state doesn’t support the use of asbestos, the CAOC said in a letter of support.
“… Whether the legislature chooses to recognize a ‘state rock’ or not, and what rock is designated, has absolutely nothing to do with lawsuits over the health effects of asbestos,” Preston said in an email.
SB 624, which received bipartisan votes in committee, is awaiting a full vote in the Assembly.


Neither the Kazan, McClain nor Waters & Kraus nor other California asbestos litigation firm has ever brought a lawsuit alleging their client's asbestos related disease is caused in whole or part to exposure to naturally occurring California serpentine rock. Moreover, there is not one epidemiological or other scientific study that convincingly shows asbestos in naturally occuring California serpentine causes asbestos related disease (See, Pan, et al., 2005). To load the bill with adjectives describing serpentine as "deadly" is misleading and inflamatory. This is wrong, furthermore, because it abrogates geological and historical reality. This has to be seen as an effort to burnish the bills supporters' abilities to attract clients, encourage litigation and fan fear among citizens (especially in areas studied by the DTSC in El Dorado County). The Legislature should look at the science, talk to its government scientists at the DTSC and then get back to working on bigger issues (like a budget) and not be sucked into this.

As I understand it, serpentine is not all that dangerous unless you inhale it...so just stop snorting it and you'll be fine.
Other states have dangerous rocks as well, that are not so easily dealt with. The state rock in both Missouri and Wisconsin is basically "Lead Ore"...perhaps they should change theirs quickly before some of it ends up in their drinking water or their plastic toys. (class action suit idea)
...and why loose sleep over all the dangerous state rocks, when there state animals that could cause bodily injury? Has anyone tried to sue California for being attacked by a grizzley bear? Can people in Florida sue if an alligator bites them? The West Virginia animal is a rattlesnake I think....the lawsuit ideas here are limitless.

To Chris Wood. That isn't precisely true. Not precisely. I worked on two cases brought by these asbestos litigation firms, one which did indeed claim the real cause of disease as environmental (though they named the wrong fiber type and serpentine), the other skated the issue because it is a slightly harder case to make although the cause was life long exposure to natural occurring Tremolite. The Pan investigation, which I inspired, was a first attempt in California although such papers have successfully delineated epidemics caused by Tremolite, Crocidolite and Erionite in literally hundreds of areas of the world. (See Metsovo, New Caledonia, Crete, Cyprus, Turkey, China, Australia, etc etc ad infinitum).
The main reason these law suits aren't common knowledge, or more importantly the attorneys sue the wrong people for the wrong reasons, is that there is a set list of defendants who settle quite easily. If I were an attorney I would not bring a case that was hard to delineate, when there is a whole group of really wealthy defendants out there who cave in quite readily, relatively.
As it works out, somewhere slightly less than 1/2 of all mesotheliomas worldwide, are caused by exposures to natural occurring amphibole and erionite deposits or sources. It is no different in California. Probably no to very very few of these mesotheliomas are caused by Serpentine....ground up and snorted or not. In the case of Tremolite we see that the diseases are not just mesothelioma but strong lung disorders in about 20% of the isolated population exposed. We don't see this 20% with environmental serpentine.
So although I agree with you basically regarding Serpentine, the elephant in the room in California are the Tremolite deposits mapped in California in the early 1960's (and the extreme likelihood that we have erionite deposits in California also). These are not serpentine and they generate human as well as some animal disease just as easily and readily as this material does in other parts of the world. We simply have a legal structure that helps hide it all from the future victims.

Re: tremolite:"These are not serpentine and they generate human as well as some animal disease just as easily and readily as this material does in other parts of the world. We simply have a legal structure that helps hide it all from the future victims." Well said.
It might not be as well known as serpentine but that does not mean it is safe: http://www.weitzlux.com/asbestos-tremolite-defined_1935837.html
