In response to a request from the Governor's Expert Advisory Panel concerning reoccupance guidelines for the New Mexico State Highway Department General Office Building, background levels of polychlorinated biphenyls (1336363) (PCBs), polychlorinated dibenzofurans (PCDFs) and polychlorinated dibenzo-p-dioxins (PCDDs) were determined in three office buildings (SIC-9199) located in Santa Fe, New Mexico. Fresh air intake plenums were sampled, surfaces in high skin contact areas were tested for (PCBs), (PCDFs), and (PCDDs), and interior surfaces of plenums were tested. Levels of PCBs on surfaces ranged from nondetectable to 5.9 micrograms/square meter (microg/m2), and in the air intake plenums from nondetected to 34 microg/m2. Concentrations of PCDFs and PCDDs on surfaces ranged from 0.04 to 0.42 nanograms (ng)/m2. Concentrations in the air of the building ranged from nondetectable to 0.18 microg/m3 for PCBs and from 0.15 to 1.5 picograms (pg)/m3 for 2,3,7,8-tetrachloro-dibenzo-p-dioxin (1746016). The author concludes that these levels were all below the reoccupancy guidelines which had been established prior to this incident.
