| factors contributing to the contamination of hospital water distribution systems by legionellae. | to identify factors associated with the contamination of hospital water distribution systems by legionellae, 84 quebec hospitals provided 3284 hot water specimens from 839 different sites. concentrated samples were seeded on buffered charcoal yeast extract agar and a semi-selective medium. at least one water sample was contaminated by legionellae in 57 hospitals (67.9%). in 22 hospitals (26.2%), greater than 30% of samples were contaminated by these bacteria. in 9 (12.2%) of 74 hospitals, distil ... | 1992 | 1538162 |
| concentrations of bisphenol a in the composite food samples from the 2008 canadian total diet study in quebec city and dietary intake estimates. | a total of 154 food composite samples from the 2008 total diet study in quebec city were analysed for bisphenol a (bpa), and bpa was detected in less than half (36%, or 55 samples) of the samples tested. high concentrations of bpa were found mostly in the composite samples containing canned foods, with the highest bpa level being observed in canned fish (106 ng g(-1)), followed by canned corn (83.7 ng g(-1)), canned soups (22.2-44.4 ng g(-1)), canned baked beans (23.5 ng g(-1)), canned peas (16. ... | 2011 | 21623504 |
