SUNNYSIDE, QUEENS — Western Queens has the most harmful pollutants in the borough, according to a new study.

Sunnyside and Woodside have the highest level of fine particles — which the city calls the most harmful urban air pollutant — in Queens and the second-highest level citywide, the city's health department found in its annual air quality survey.

The city looked at pollution levels in 2017, the most recent year of data, to put together its findings. It is not yet clear how air quality may have changed since then.
