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 will measure levels of 1-nitropyrene (1-NP) metabolites in urine to assess diesel exhaust exposure in residents of Oakland, Richmond, and San Pablo.  The areas included in the study were chosen based on information from CalEnviroScreen. We will recruit 50 families with a child aged 3 to 6 and collect urine samples from the child and one parent.  Samples will be collected in two different seasons (winter and spring). The project design will allow us to compare 1-NP results within a household, across age, between communities, and by season. 

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 will also be analyzed for 1-NP.
