From: dakatz45**At_Symbol_Here**msn.com Subject: Re: [DCHAS-L] mercury- final questions Date: November 24, 2007 11:15:16 AM GMT-05:00 I have read Alan Hall's excellent response to the teacher concerned with mercury contamination in his school. However, I do have a concern regarding that response. Before testing himself and his children through a toxicologist, I believe his first concern should be determination of the amount of mercury in the rooms as established by testing with the Lumex 915. The results of that testing should guide subsequent actions. I would not have the individual and his family go through medical evaluations if there was no mercury contamination in the workplace. If the presence of mercury is established in the workplace, then, evaluation by a qualified medical toxicologist would be the logical next step. I would never downplay the effects of exposure to mercury contamination, nor having testing done on a facility where there was a history of mercury spills, but mercury has gotten such a bad rap in recent years that there exists some unreasonable fear (panic?) of mercury and its compounds. At my institution, we have just had to deal with an individual who tried to start a panic over a very small amount of mercury(II) chloride which is included in a standard laboratory kit for medical lab technicians. (All the mercury chloride is used up in the laboratory procedures.) As a trained chemist with long time safety involvement, my main concern was that all individuals were properly trained in the proper handling, use, and disposal of the compound and that there were no excessive amounts that required storage in our facilities.
