Will you also admit that different compounds have different toxicities? Why sure. Mercury chloride From Wikipedia -'Mercury(I) chloride is the chemical compound with the formula Hg2Cl2. Also known as calomel or mercurous chloride' and ........." Due to its low solubility, mercurous chloride is less dangerous than its mercuric chloride counterpart. From the early 1830s through the 1860s, this compound was used as a laxative in the U.S. This previous use in medicine as a diuretic and purgative was discontinued because of its toxicity." .http://en.wikipedia.org/wiki/Calomel again from Wikipedia .... 'Thiomersal (INN) (C9H9HgNaO2S), formerly and still commonly known in the United States as thimerosal, is an organomercury compound (approximately 49% mercury by weight) used as an antiseptic and antifungal agent." and " Thiomersal is harmful by inhalation and ingestion, lethal between 50 and 1000 times[citation needed][1] the usual intake (hazard symbol T+).[2] It is a neoplastigen and a teratogen. Thiomersal is also dangerous for the environment (hazard symbol N). For more safety information on how to handle thiomersal, consult its MSDS (material safety data sheet). Thiomersal causes susceptible bacteria to autolyze (break down their own cells with self-produced enzymes) via an unknown mechanism. [citation needed] In the body, it is metabolized to ethylmercury (C2H5Hg+) and thiosalicylic acid.[3]" Mercury cloride has been used as a laxative { did doctors really understand the risk] Thimerosal is much more toxic. Of course any substance with mercury is a potential toxin. As you know a great deal about chemistry and biology why would you intimate otherwise. Thanks Vince |

Thimerosal is much more toxic. Uh, dude, the LD50 of thimerosal (oral testing in rats) is 75 mg/kg. Mercury chloride's LD50 is 1 mg/kg. Of course any substance with mercury is a potential toxin. Any compound has *potential* toxic effects, even dihydrogen oxide. As you know a great deal about chemistry and biology why would you intimate otherwise. Thanks Vince Oh, I don't know. Maybe because of all the evidence? |
