First, the good news: air pollution in New Jersey has been steadily improving over the years
Trends of Criteria Pollutant levels in New Jersey

However, levels of air toxics (HAPs) remain among the highest in the US
HAPs: Hazardous Air Pollutants; DEP: Diesel Exhaust ParticlesData Sources: USEPA (NATA, 2018 release) and NJDEP

New Jersey and in particular the Newark/Elizabeth area have some of the highest Diesel Exhaust Particle (DEP) air levels in the US
Note: map colors are based on multiples of the “California cancer health benchmark” for DEP, 0.0033μg/m3; so 0.34-0.66 μg/m3 is 100-200 times, 0,67-0.99 is 200-300 times, and 1.0-1.65 is 300-500 times the benchmark

Annual average concentrations across census tracts do not capture the high levels caused by proximity of urban populations to sources

~7% of the population of Elizabeth lives within 50m from sources of toxic air pollutants; air concentrations there are 50-500% higher than urban background
