Risk Assessment of Exposure to Trans Fat in Canada
Trans fats are undesirable because they raise LDL cholesterol and lower HDL cholesterol levels in the blood, which can lead to an increased risk of coronary heart disease. In the mid 1990’s, researchers estimated that Canadians had one of the highest average trans fat intakes in the world, estimated to be approximately 3.7% of energy. The World Health Organization recommends that average intak...
متن کاملAn updated assessment of radon exposure in Canada.
Based on data from a national residential radon survey performed in 18 cities in Canada in the 1970s, an annual effective dose to the Canadian population due to indoor radon exposure was estimated at 0.71 mSv. An updated estimate of radon exposure in Canada has been made using additional indoor radon data from recent surveys in Ontario and Nova Scotia, and in 28 communities of British Columbia ...
متن کاملA Preliminary Thoron Survey in the Upper Midwest
Although thoron (2201Zn) was recognized as a potential source of radiation exposure in homes twenty yearsago, only a few homes in the United States have been measured for thoron. Early indoor surveys suggested that thoron concentrations would generally be low, highly variable, and make a poor surrogate for thoron pro eny dose. Howeyer, 522 recent reports of significant thoron interference with ...
متن کاملOccurrence of trichothecenes in Argentinean beer: a preliminary exposure assessment.
The presence of trichothecenes (deoxynivalenol, 3-acetyl deoxynivalenol, 15-acetyl deoxynivalenol, nivalenol, neosolaniol and diacetoxyscirpenol) was studied in 50 samples of Argentinean beer (nine different brands). Gas chromatography with electron capture detector was used for identification and quantification of these mycotoxins. The only mycotoxin detected was deoxynivalenol (DON). It was p...
متن کاملThe HMGU thoron experimental house: a new tool for exposure assessment.
A thoron experimental house was constructed in a laboratory room of Helmholtz Zentrum München to perform exposure studies of thoron and its decay products under controlled conditions. The single room house (7.1 m(3)) was built from unfired clay stones and clay plaster. For the plaster of the inner side, the clay was mixed with granite powder enriched with (232)Th. The thoron inventory increased...
