摘要:ABSTRACT(#br)Dental amalgam is 50% metallic mercury (Hg0) by weight and causes Hg exposure. The first assessment of Hg exposure and risk from dental amalgam in Canada was published in 1996. Recent data provided the opportunity to update that assessment. During the...

摘要:ABSTRACT(#br)In order to provide dust ingestion rates that can aid the interpretation of indoor dust measurements as surface loadings ( i.e. , units of µg/m2), dust ingestion rates have been developed for various age groups on a surface area basis. The approach in...

摘要:ABSTRACT(#br)Risk-based concentrations (RBCs) for lead (Pb) in soil were estimated using equations for development of Canadian soil quality guidelines. Based on the latest toxicological assessments by various health agencies, risk specific doses for Pb were defined for child...

摘要:ABSTRACT(#br)Soil ingestion rates calculated using a tracer-based mass balance approach may carry considerable study errors, insensitivities, and “artefacts” of analysis that result in significant uncertainty. These same soil ingestion rates are often used as surrogates for ...

摘要:It has been hypothesized that concentrations of mercury ([Hg]) in fish increase with increasing acidic deposition. Our investigation suggests that this hypothesis is false for three species of fish from Ontario lakes. Across Ontario, Canada, slightly lower average [Hg] in Lake Tr...

摘要:Dental amalgam is approximately 50% mercury (Hg) by weight, and persons bearing amalgam fillings are exposed to this element, primarily as Hg vapor. For Canadians with amalgam-filled teeth, it was estimated, based on two independent models, that Hg exposure from amalgam aver...

摘要:Concerns have been expressed regarding the health risks posed by chemical exposures from dental restorative materials. Dental materials are exempted from the pre-market review provisions for medical devices in Canada and, therefore, information on the risks of potential chem...
