Evaluation of the Results of Whole Blood Volatile Solvents Testing, Chemist Wilma Subra for Lower Mississippi Riverkeepers, October 25, 2010:

Samples of blood were collected on August 2, 3, 12 and 18, 2010 from three females, age 44, 46 and 51, and five males, age 30, 46, 48, 51 and 59, who were residents and BP cleanup workers in Alabama and Florida. The whole blood samples were analyzed for Volatile Solvents by Method 0762, by Metametrix Clinical Laboratory in Pensacola, Florida.

Ethylbenzene and m,p-Xylene

The three females and five males had whole blood levels of Ethylbenzene and m,p-Xylene in excess of the NHANE 95th Percentile values of 0.11 ppb for Ethylbenzene and 0.34 ppb for m,p-Xylene.

The highest Ethylbenzene concentration was in the blood of the 48 year old male, whose value was 4 times the 95th Percentile value. The second highest concentrations of Ethylbenzene were almost three times the 95th Percentile and occurred in the 59 year old male, 46 year old female, and 51 year old female.

The m,p-Xylene concentrations were the same in the three females and five males, 4 times the 95th Percentile. ...

All eight individuals tested had Ethylbenzene and m,p-Xylene in their blood in excess of the NHANES 95th Percentile. ...

Ethylbenzene, m,p-Xylene and Hexane are volatile organic chemicals that are present in the BP Crude Oil. The blood of all three females and five males had chemicals that are found in the BP Crude Oil.
