Based on the analysis of the PM 2.5 data for New York City, it was found that the city has the highest concentrations of PM 2.5 from January through March and is most widely spread in July through September. It appears that throughout the year, there is pollution along the east coast of Manhattan and Staten Island. These area are closest to New Jersey. There could be several reasons for the high levels of pollution such as rush hour and heavy traffic into the city, manufacturing and energy activities that take place in neighboring New Jersey or it may be more based on wind patterns. There may be air of cleaner quality coming from the ocean in Brooklyn and Queens rather than the air that is measured in Manhattan and Staten Island.
On each seasonal map, the top most heavily polluted census tracts are highlighted. Though the most polluted census tracts vary greatly with each season, the areas tend to be located in Manhattan and Staten Island, posing unique public health issues to the affected communities. As such, it may be necessary for New York City to consider new methods to improve the air quality for residents of Manhattan and Staten Island.
