<p>I'm curious of people's observations of Princeton New Jersey's air quality. I understand New Jersey in general has poor air quality, but I've been having difficulty finding whether certain cities are better than the state in general. Or, maybe the pollution from the nearby cities (NYC, Newark, Philadelphia, Trenton, etc) causes Princeton's air also to be poor.</p>
<p>Also, how does the air quality in Princeton NJ compare to New Haven CT ?</p>
<p>The New Jersey air quality at Princeton is poor, like most U.S. metropolitan areas. With the many chemical plants near Newark, the cities of Philly, NY, and the huge amount of auto traffic, the pollution is noticeable. (The tap water has a questionable taste and odor, too.) However, the many trees in the Princeton area help the situation. </p>
<p>How or if you may notice it probably depends where you are coming from. Compared to LA, the P’ton air might seem fresh, compared to the top of the Grand Teton, not so much. </p>
<p>Can’t give a comparison to New Haven, sorry.</p>
<p>I’m afraid there isn’t much to distinguish Princeton from Yale in this regard. Both suffer from being near NYC with its accompanying air pollution. According to the 2010 “State of the Air” report from the American Lung Association, both schools are in areas where they are given a grade of “F” for both particulate matter and ozone.</p>
<p>New Haven (Yale) is ranked worse for particulate matter (21 warning days as compared to 10 for Princeton) and Princeton is ranked worse for ozone (37 warning days as compared to 27 for New Haven).</p>
<p>On the other hand, this is the first time I’ve ever heard of anyone asking this question. I don’t think you would really notice an air quality problem in either place unless you were coming from an area far from major cities.</p>

<p>It appears princeton’ nj’s air is similar to NYC’s air, in the link you provided, for Mercer County. But, I wonder, with princeton nj being away from the cities (newark etc) if the air is much better than the air reading for the county generally (?). There is no air reading for princeton nj itself.</p>
