If I read the EPA's probabilistic risk assessment for children's exposure correctly, it appears there's about a 10^-5 risk of arsenic-related cancers due to playground exposure. Not something I really want to rely on, simply because such estimates are so dependent on multiple assumptions. (Or, as sometimes occurs with environmental estimates, are simply bogus.)

But what I suggest is going to the prerule Federal Register discussions for the Arsenic standard and there would be studies specifically related to occupational exposure there on which the rule is based. And I believe there is proposed regulation specific to the wood preservatives and there should be some references there to good studies.
These memories are from the days when I got the FR in hard copy every day. I now search the site on line. It's still the best source for this kind of information in my view.
Since I take inquiries every day from the general public and have for 40 years, I'll also provide a bit of advice. The first things you want to identify for yourself is why the person wants to know, and what you can read between the lines is the opinion that person actually hopes to hear from you. They all have a motive. Sometimes that either helps you in your search or it short circuits the work because you can find another way to get to the heart of the inquiry.
I say this because it is odd they are looking for occupational exposure during "use" and exposure of children to what? Items made with the wood? To the dust from cutting the wood at home? Is this person a contractor being sued for installing this stuff or a householder looking to sue a contractor? What?
Life is short. Find the short cuts. Monona

Subject: [DCHAS-L] Arsenic in CCA wood
I've had a bunch of questions from a member of the public referred to me regarding arsenic exposure from chromated copper arsenic-treated wood. A brief literature search showed me that there's quite a bit of data and zillions of papers out there, but much of it is not quite what I'm looking for.--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchasIs anyone aware of a good reference, preferably a review, that discusses CCA wood exposure hazards, particularly routes of exposure and toxicokinetics in both occupational use and in children? It would help short-circuit my lit search considerably.Thanks in advance.Regards,DanDaniel Reid Kuespert, PhD, CSP11101 Wood Elves WayColumbia, MD 21044410-992-9709
