Journal of Occupational and Environmental Medicine. (2014, September 8). Air pollution may affect levels of obesity-related hormone. ScienceDaily. Retrieved November 23, 2014 from www.sciencedaily.com/releases/2014/09/140908120012.htm

To figure out whether higher exposure to traffic-related air pollution cause higher levels of obesity-related hormone, Gregory A. Wellenius, ScD, of Brown University and his colleagues decided to investigate the issue.  They did this by measuring the traffic-related air pollution of Boston and the blood leptin levels of some of 765 adult people.  Although the result can’t prove any casual link of the issue, the link between the black carbon exposure and leptin levels might help.

It is reasonable to have a study of whether or not air pollution causes higher levels of obesity-related hormone.  Since there are numbers of consequences an air pollution is able to produce, the issue relating to the article is an addition.  In theory, this article and any other articles relating to air pollution interpret the fact that air pollutants are dangerous that if no immediate action was done, all the people will be having numerous diseases that results from air pollution.
