As part of a demonstration project evaluating results of lead exposure following low level soil treatments conducted in Boston Massachusetts, research staff collected dust wipe and dust mat samples to evaluate efficacy of treatments. This paper will describe changes observed over time in floor dust lead loadings and in accumulation of lead dust on floor mats for 47 properties enrolled in the evaluation. Samples were obtained at two points in time: before soil lead treatment and after soil lead treatment, about one year later. For 17 properties, samples were also collected immediately after treatments had been completed. Six dust wipe samples were typically collected for each property, including front and rear exterior and interior floor samples. One dust mat sample was collected for each property, just inside the primary entrance door to the property.

Note: As of 2/01/02, data from this project are being data-entered and results are not yet available.

Learning Objectives:

• Describe changes in lead dust levels following low level soil interventions conducted in Boston.
• Compare rates of change in dust lead levels using dust wipe and door mat samples.

Keywords: Lead, Environmental Exposures
