The Ra content was determined by their radioactive descendants’ concentrations.For the second sampling point, both models could be used.The measurement time for each sample was standardized at 50 minutes, cover with a plastic thin layer for Pb CIC model (Figure 4, Figure 5, Figure 6, Figure 7) and the CRS model (Figure 10 and Figure 11) to sediment cores collected at different stations.
We could conclude that the top sediment interval had been there 30 years ago.
The precipitate was heated in a water bath, where the elemental sulfur is formed while lead remains in solution.
The solution was filtered through Whatman filter paper (blue ribbon) with the addition of 10 m L 40% ammonium acetate.
I plan and participate in some of our remote field collections.
As well, I develop analytical methods, and maintain the analytical equipment in our lab, some of which are part of the My background was originally in marine and freshwater biology, but I have now moved into environmental organic contaminant analysis, primarily focusing on persistent pollutants and polycyclic aromatic hydrocarbons.
