Use this article to answer questions about mass spectrometry and how it was used to identify lead isotopes in the air around Mexico City.
Determination of Particulate Lead Using Aerosol Mass Spectrometry: MILAGRO/MCMA-2006 Observations
(Ok I read the article and I just can't understand the dialect used I have included what I have so far)
1. What were some purposes of the investigation?
Some of the investigations purposes were to learn about the emissions and processing of pollutants as well as the dispersion, transport, and transformation of pollutants in the atmosphere. Another purpose was to learn how about pollutants health risks and their effects on the population.
2. What were the locations of the aerosol mass spectrometers (AMS)?
AMS was located at TO.
3. One problem the researchers faced was an uncertainty about whether the signals observed in certain mass spectrometry data were, in fact, due to lead isotopes. Explain why this was a problem. In other words, why wasn't information about the mass of the isotopes sufficient for identifying the isotopes? Provide an example to explain your answer.
4. How did the researchers address the problem described in question 3? Do you believe that their method was adequate? Justify your response.
5. Analyze the graph in Figure 4 of the article. Describe the vertical and horizontal axes, and explain how the isotopes are identified by the graph and what the heights of the curves mean.
6. Figure 11 in the article shows a way that researchers used data they obtained from mass spectrometry. Summarize the information about lead isotopes contained in each graph. Explain what conclusions the researchers could draw from these graphs.
I would very much appreciate the help
