As Judy McAuley chats with customers at her baby supply store, a small white box on the counter flashes numbers on its digital display: 20, 19, 21. The customers at Happy Baby Company stop to look before paying for natural teething necklaces, cloth diapers and BPA-free baby bottles.
The box is an air quality monitor called the Speck Sensor, and it’s telling Ms. McAuley that the air inside the store is relatively low in a specific and dangerous type of pollution. This is important to her because, like many businesses along Lincoln Avenue in Bellevue, a borough northwest of Pittsburgh, Happy Baby is next to the Shenango coke works.
“The air gets weird and stinky in the summer,” said Ms. McAuley, who lives nearby. “You hear about how asthma rates are through the roof around here.”
