In sediments, there are a number of chemical forms of heavy metals, and they generally present different physical and chemical behaviors in terms of chemical interaction, mobility, biological availability and potential toxicity. It is easy to find out the total heavy metal contents in the river water or in the sediment. However, it is metal speciation into different fractions that will help us to understand the potential effect of contamination of heavy metals.
I collect water and bedload samples in North Saskatchewan River and try to identify and quantify the mode of occurrence of heavy metals in sediments. Also, I will figure out the total heavy metal contents in the river water and the characteristics of the bedload. The techniques that I am using include Sequential Extraction, Digestion, XRD, etc. If you have any questions about my project or if you would like to get involved, please feel free to contact me.
