FAQs

What are these things hanging on telephone poles?

You might have noticed some strange-looking devices hanging on telephone poles. These are two types of air monitors that measure different types of air pollution. You might see both of them hanging on the same telephone pole, or just one at a time.

1. The UPAS

These boxes are air monitors called Ultrasonic Personal Air Samplers (UPAS). They measure tiny particles (also called “fine particulate matter” or PM_2.5) to determine how much pollution is in the air.

2. VOC Monitor

Inside this metal housing is a tube that catches Volatile Organic Compounds (VOCs) in the air. VOCs are a group of chemicals that include benzene.

Can the air monitors hear or see me?

No! The air monitors are very simple devices. All they do is let air pass through them and catch pollutants. There are no microphones or cameras on these devices, since you can’t hear or see air pollution!

Who put the air monitors up?

The air monitors are part of an ongoing community air monitoring project called THRIVEair. This project is a partnership between Drexel University and Philly Thrive, a local environmental justice organization.

What are the goals of this study?

The goal of THRIVEair is to get a better idea of the air pollution levels in Grays Ferry and other neighborhoods that surround the former Philly Energy Solutions Refinery site. This information will be used to advocate for the health and wellness of the community.

Where can I find the results of this study?

As data become available, results will be shared with community members through online resources, printed fact sheets, and public events. Check out our results page and events page for updates!
