Do Questions Reflecting Indoor Air Pollutant Exposure from a Questionnaire Predict Direct Measure of Exposure in Owner-Occupied Houses
Home characteristic questions are used in epidemiological studies and clinical settings to assess potentially harmful exposures in the home. The objective of this study was to determine whether questionnaire-reported home characteristics can predict directly measured pollutants. Sixty home inspections were conducted on a subsample of the 2006 population-based Toronto Child Health Evaluation Questionnaire. Indoor/outdoor air and settled dust sampl…
Exploring Variation and Predictors of Residential Fine Particulate Matter Infiltration
Although individuals spend the majority of their time indoors, most epidemiological studies estimate personal air pollution exposures based on outdoor levels. This almost certainly results in exposure misclassification as pollutant infiltration varies between homes. However, it is often not possible to collect detailed measures of infiltration for individual homes in large-scale epidemiological studies and thus there is currently a need to develo…
Sealing and retentive characteristics of Ottawa Clay
The seepage of contamination to ground aquifers has recently drawn due attention from the general public and governments in many countries. Surface disposal of solid waste remains to be a viable option in the waste management field. Natural geobarriers have evidently failed to totally isolate hazardous contaminants for long periods. Water plays a dual role in mobilizing and transporting toxic constituents, especially in the vadose zone. Accumulat…
Till liners for isolation of hazardous solid wastes
Migration of hazardous elements from abandoned solid wastes disposal sites has been identified as a major threat to degradate the quality of ground waters. Although earthern liners have acid‐consuming and sorptive capacities, a persistent question remains unanswered regarding the leachate‐induced alteration of their sealing properties. This brings into play one of the two mechanisms (advection or diffusion) as being a prominent transport route. D…
Leachability of hazardous elements from uranium tailings
Due to the usually low grades of metals in natural ores, huge amounts of solid wastes are annually produced from various mining/milling processes. Both these processes and the types of ores in question determine the proper waste disposal strategy. In yellow cake (U3O8) production, extractive hydrometallurgical processes along with oxidizing, acidic reagents are being widely used. Uranium ores usually contain substantial amounts of pyrite (FeS2), …
Sign Language Research and Linguistic Theory
Linguistic theory has traditionally defined language in terms of speech and has, as a result, labelled sign languages as non-linguistic systems. Recent advances in sign language linguistic research, however, indicate that modern linguistic theory must include sign language research and theory. This paper examines the historical bias linguistic theory has maintained towards sign languages and refutes the classification of sign languages as contriv…
