Nasser Publishes on Bioindicators of Arsenic Contamination

Friday, April 29, 2016

Ph.D. student Nawaf Nasser in the field Ph.D. candidate Nawaf Nasser recently published in the Journal of Microbial Ecology. He is the first listed author on the article, entitled "Lacustrine Arcellinina (Testate Amoebae) as Bioindicators of Arsenic Contamination." 

The Yellowknife, NWT region is known to be contaminated with arsenic. This is largely the result of several gold mines, specifically the Giant Mine (1948-2004), which was one of the largest and most productive gold mines in Canadian mining history. Although it was shut down in 2004, the arsenic levels in the vicinity of the mine and the city itself remain a concern. High levels of arsenic contamination were found in many lakes in the region.  

In his paper, Nawaf discusses how he used a bioindicator, called Arcellinina (or testate amoebae), to determine whether this proxy could be used as a sensitive and reliable indicator for arsenic contamination intensity and remediation rates in lakes.
