EXPOSURE INVESTIGATION REPORT

SOLUTIA INCORPORATED/MONSANTO COMPANY
ANNISTON, CALHOUN COUNTY, ALABAMA


CONCLUSIONS

  1. Five of 43 adults had an elevated blood PCB level (> 20 ppb).


  2. Blood PCB levels in 37 children were not elevated.


  3. Blood PCB levels were correlated with age and length of residency near the Solutia facility. Available evidence suggests that PCB exposures in the past may have exceeded more recent exposures.


  4. PCB concentrations in excess of 1 ppm were detected in surface soil samples from four homes and in house dust samples from two homes.


  5. Blood PCB levels were not correlated with soil or house dust PCB levels.


RECOMMENDATIONS

  1. Homes with PCB contamination in soil in excess of EPA action levels should be evaluated for possible remediation.


  2. Residents should minimize further exposure to areas of known PCB contamination.
