Kolp PW, Williams PL & Burtan RC. Assessment of the Accuracy of Material Safety Data Sheets. Am Ind Hyg Assoc J 56:178-183 (1995)

Abstract: "This study evaluated 150 material safaety data sheets (MSDSs) for the accuracy and completeness of five areas of information: (1) chemical identification of hazardous ingredients; (2) reported health effects; (3) suggested first aid procedures; (4) recommended personal protective equipment; and (5) exposure levels regulations and guidelines. The material from each MSDS was reviewed by both an industrial hygienist and an occupational physician using standard (secondary) references (that were readily available at the time the MSDS was prepared) and a rating system for each area of information. Eighty-nine percent of the MSDSs provided identifiable chemical names. Thirty-seven percent were found to have accurate health effects data (with chronic health information the most inaccurate). The majority of MSDSs (76%) provided adequate first-aid information. Slightly less than half (47%) were judged to have an accurate rating for personal protective equipment information or a correct listing for applicable occupational exposure limits."

Langworth S, Kolbeck K-G & Akesson A. Mercury exposure from dental fillings II. Release and absorption. Swed Dent J 12:71-72 (1988)

NO ENGLISH Abstract AVAILABLE. CITATIONS FROM THE TEXT FOLLOWS: "...To get an appropriate estimation of the absorbed amount of mercury released from dental amalgam, we made parallel measurements of oral and tracheal air-concentrations of mercury in ten individuals with 8-54 amalgam surfaces, (mean = 25) with an abrasive tooth-paste... As demonstrated in the table, the tracheal mercury concentrations were considerably lower than the intra-oral levels. During inhalation through the nose, there was no measurable mercury concentration in the trachea, i.e. mercury concentrations below 1ug/m3 which is the sensitivity limit of the detector. The low mercury concentrations in tracheal air are probably due to a dilution of the small volume if intra-oral air (40-50 ml) containing mercury vapor with more than ten times greater volume of inhaled air with a very low content of mercury. There may also exist some degree of mercury binding and inactivation in the mucous membranes of the airways. We have estimated the average daily mercury absorption from amalgam fillings based on mercury concentration in tracheal air of about 2 ug/m3 during four hours of "stimulated" conditions and a five fold lower concentration during 20 hours of "unstimulated" conditions. With a ventialtion of 10 m3/24 h, nose breathing about 50% (without mercury content) and a alveolar mercury absorption of 80%, the daily mercury uptake from amalgam fillings is estimated to be about 3 ug. As a comparison the mercury uptake during a work-day at the TLV exposure level (50 ug/m3), is calculated to the about 200 ug..."

Laundy T, Adam AE, Kershaw JB & Rainford DJ. Deaths after peritoneal lavage with mercuric chloride solutions: case report and review of the literature. Br Med J 289:96-98 (1984)

Abstract: "Mercuric chloride solutions have been used in operations for over 30 years in attempts to kill cancer cells implanted on healthy tissue. Three applications have emerged. The most common is the use of 1/500 and 1/1000 solutions to wash out the bowel lumen during operations for colorectal carcinoma. The second is simple wound irrigation to prevent recurrences in the scar, particulary in breast cancer. the third is intraperitoneal application where seeding of a visceral cancer is feared. All these applications carry the theoretical risk of mercury absorption and nephrotoxicity. Documented examles of acute renal failure and death have occurred after peritoneal lavage and include two cases from this unit. The first (unpublished) death after peritoneal lavage was reported to the Committee on the Safety of Medicines in 1977. We report the 10th case of a serious adverse reaction - and the fifth known death - after peritoneal lavage with a mercuric chloride and review other published cases."

Lichtenberg HJ. Elimination of symptoms by removal of dental amalgam from mercury poisoned patients, as compared with a control group of average patients. J Orthomol Med 8:145-148 (1993)

Abstract: "The findings presented here suggest a correlation between many health complaints and mercury amalgam fillings. Removal of amalgam fillings results in significant improvement of these symptoms. These same symptoms which are improved or eliminated in amalgam-removal patients are present but undiagnosed in the general population."

Lindqvist B & Mornstad H. Effects of removing amalgam fillings from patients with diseases affecting the immune system. Med Sci Res 24(5):355-356 (1966)

Abstract: "53 patients with complaints which they attributed to their amalgam fillings, and with pathological tests indicating abnormality of the immune system, were followed for 1-3 years after the removal of all, part of, or none of their amalgam fillings. Within the group of 34 individuals who had all their amalgam fillings replaced, there was a significant number of decreased antibody titres, but only two had normalised their laboratory tests after 1-3 years. A significant improvement in subjective symptoms occurred in 20 (59%) of cases. In the group of patients who still had amalgam fillings, there were no statistically significant changes in the antibody titres. It thus seems that mercury released from amalgam fillings may initiate or support an ongoing immune disease. However. this study group was rather heterogeneous, and had received various pharmacological treatments. Further studies, are, therefore, needed to confirm, or refute, the results"
