A method was developed and validated for the extraction and determination of total iodine (I) in food composite samples, representing different foods available on the Canadian market, by inductively coupled plasma-mass spectrometry (ICP-MS). Prior to analysis, samples were digested in a closed microwave system using a mixture of nitric acid and perchloric(More)
A method based on solid-phase extraction followed by HPLC analysis with fluorescence detection was developed for the determination of bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE) in liquid infant formula. In this method, instead of trying to isolate and measure each individual form of the molecules, hydrolysis of BADGE,(More)
Food composite samples from the Canadian Total Diet Study which was conducted each year from 2008 to 2012 rotating between different cities were analysed for bisphenol A (BPA). The overall levels of BPA in the composite food samples from each of the five years from 2008 to 2012 were similar in general with averages (range) of 7.7 ng/g (0.20-106 ng/g), 7.8(More)
In Nova Scotia, Blanding’s turtles (Emydoidea blandingii) exist in a disjunct population complex at the extreme northeastern area of the species range. Pleasant River Fen in southwestern Nova Scotia provides habitat for one group within the Nova Scotia population. A ca. 10,000-year multi-proxy record to determine environmental variability at Pleasant River(More)
