Streetlight Sensors Measure Spokane Air Quality

For the last several days, you’ve seen with your own eyes the wildfire smoke that is hovering over our region. But other sets of ‘eyes’ have also been ‘seeing’ that smoke and taking samples of it. Among those ‘eyes’ are three sensors that sit on the tops of streetlight poles in Spokane’s University District. Brian Lamb, a professor of atmospheric research at Washington State University, says all of the sensors are showing elevated levels of particulates from the smoke.

But, Lamb says, when the smoke is gone, the sensors show some interesting air quality differences that confirm the phenomenon that we know as microclimates.

A new study by WSU researchers has found that toxic effects of exposure to mercury in fish can be passed on to later generations.

The WSU School of Biological Sciences study looked at zebrafish that were exposed to very low levels of methylmercury, which occurs in nature when mercury is metabolized by small organisms.

It found that the toxic effects of exposure were passed on not only to their offspring, but also the third generation of zebrafish.

The toxic effects were neurological and included abnormal locomotion, impaired vision, and hyperactivity.
