there is an issue in generalizability when apply the research finding from one population to another. You have to compare the characteristics between the two population. What is the difference in exposure level between the group in published paper and 四川的安置房residents? If you don't know the difference,you can not draw conclusion based on the published data. Of course, other factors are need to taking into consideration.

BTW, I can find the range of exposure from the paper (0.4–3.5, 0.6–1.3, 0.01–0.04c, 0.01–1.0c).
