Objective:
- To measure Mn, PBDEs and DDT/E in shed deciduous teeth (Population: CHAMACOS children participating since birth).
- To determine the relationship between Mn, PBDE and DDT/E levels in teeth with other relevant biological measures.
- To quantify the contribution of agricultural pesticide use to Mn levels in house dust, teeth and child blood.
- To identify population correlates of PBDEs and DDT/E exposure in 9-year-old boys.
Progress Summary:
Note: This report covers the project period 8/1/2010-5/31/2011
- DAPS in child urine. We recently published an article describing organophosphate (OP) pesticide metabolite dialkyl phosphate (DAP) levels in CHAMACOS children at 6, 12 and 24 months.
- DAPs in the environment (EPA STAR Fellowship): Measurements of DAPs in urine may come from OP pesticide in child or intake of preformed DAPs. We measured preformed DAPs in dust. DAPs were present in dust but did not significantly contribute to measured DAPs in urine. A second manuscript is in review.
- PBDEs in Pregnant women and children (NIEHS): An article we recently published in Environmental Health Perspectives showed that PBDE levels in CHAMACOS children were seven times higher than similar children living in Mexico, and three times higher than levels in their mothers. The higher exposures were likely related to the use of chemical flame retardants to meet unique California flammability laws.
