When we breathe the air or drink the water, we’re taking in any potential contaminants all at once—with effects that can combine or even compound. So, incrementally, environmental protection is becoming more like real life, where exposures are not singular and isolated. It’s important to look at the bigger picture.

In the presence of heat and sunlight, chemical emissions from cars and factories react to form ozone (learn more here )., a harmful pollutant. As average temperatures rise, ozone levels accelerate. Repeated and excessive traffic pollution and poor air quality were determined to be linked to Ella's worsening asthma.

So of course the American Lung Association ’s yearly report, State of the Air (SOTA), published every year since 2000, is of professional and personal interest. The air quality for this report was calculated using data reviewed by EPA from 2020, 2021, and 2022. Ozone, too, poses significant risks to respiratory health.

Air pollution from ports comes from many sources: ships, trains, tugboats, cargo equipment, and – quite importantly – the trucks that move cargo containers to and from ports. Because drayage trucks tend to be among the oldest tractor trucks on the road, they tend to pollute at greater rates than other tractors.

To explore a small piece of what is at stake, let’s take a quick look at some of the rules currently under review at the EPA: Air emission reporting requirements If finalized and implemented, this rule will improve the way air pollution emissions are estimated and collected by the EPA.
