Beryllium concentrations in atmospheric particulate and soil samples in and around a Beryllium Processing Facility (BPF) have been measured. The mean air concentration level of beryllium in and around the fence line of the BPF is 0.48 +/- 0.43 ng m(-3) (n = 397) and is mostly influenced by diurnal and seasonal changes.
Beryllium and beryllium compounds were considered by previous IARC Working Groups in 1971, 1979, 1987, and 1993 (IARC, 1972, 1980, 1987, 1993). a thin film of beryllium oxide forms on 95. IARC MONOGRAPHS 100C the surface of the bare metal, rendering the metal an average daily concentration of less than 0.5 ng/m 3 was reported in the
The average concentration of beryllium measured in the air in the United States during the 1980s was 0.03 nanograms per cubic meter (ng/m 3). Ambient concentrations measured in 50 cities between 1977 and 1981 were 0.1-0.4 ng/m 3. (1) Assessing Personal Exposure
The concentration of beryllium used in each of the two bioassays ranged from 0.01 to 100 mg/l Be 2 +, A small quantity of isotope (e.g., 0.2 ml) was added to each 2-liter test solution.

Beryllium 10 results are plotted in Figure la for the time period from 3288 to 40,055 years B.P. (1950) (719-2252.8 m) according to the GISP2 timescale [Meese et al., 1994].
