Paulatuk Beluga whales: Health and Knowledge

From summer 2012 to 2015, field trips were organized to harvest belugas and asses their contaminants levels. During the summer 2012, a total of eleven whales were harvested. The 2013 field campaign duration was 20 days and 28 whales were harvested. In 2014, belugas were monitored for the duration of 22 days. A total of 14 whales were harvested from which three were unable to be sampled because of distance and weather for the Monitors to reach the hunters. In 2015, the program was spread out to monitor for 40 days. A total of 18 whales were harvested and 16 were fully sampled. Once the whales were harvested, different samples were collected and sent to Freshwater Institute (Winnipeg) for analyses. Ages of whales were determined using a thin section of tooth by counting individual growth layers. Liver, skin, muscle were analyzed for total mercury cold vapor atomic absorption spectroscopy (CVAAS) after an acid digest. Stable isotope analyses on liver and muscle samples were carried on at the University of Waterloo using ion-ratio, mas spectrometry (CF-IRMS). Lipids were removed from samples with a 2:1 chloroform:methanol wash for carbon readings.
