The East Bay Diesel Exposure Project is a collaboration with the Center for Environmental Research and Children’s Health (CERCH) at the University of California, Berkeley and the University of Washington.

We are measuring levels of 1-nitropyrene (1-NP) metabolites in urine to assess diesel exhaust exposure in residents of Oakland, Richmond, and other East Bay locations.  The areas included in the study were chosen based on information from CalEnviroScreen. We recruited 40 families with a child aged 2 to 10 and collected urine samples from the child and one parent at two different time points.  Fifteen of the families provided daily samples over a four-day period at each time point.  The project design will allow us to compare 1-NP results within a household, across age, between communities, and over time. 

Companion studies are being conducted to analyze 1-NP in dust from participants’ homes, and measure black carbon in indoor air.  Black carbon is a sooty material released into the air from diesel engines and other sources, and can end up in homes.  The filters from the black carbon monitors are also being analyzed for 1-NP.
