“…In 1949, the United States Atomic Energy Commission established human beryllium exposure limits.3, [239][240][241] In no instance has the effectiveness of industrial air standards been so apparent as that :stablished for beryllium. The observance of these imits has produced no new cases of beryllium disease.…”

“…13 Determination of beryllium was conducted by dry ignition of the filter paper at 700 1C and solution of the ash followed by complexing with aluminon and EDTA. Crawley 14 reported a similar method using membrane filters for collection of airborne beryllium samples. Profumo et al 17 reported a method for determination of species of beryllium in particulate matter of emissions and working areas.…”

The present work describes a simple and reproducible direct-read system for onsite monitoring of beryllium on surfaces of work areas. It is based on the colorimetric reaction of beryllium with active ingredients deposited in a swab. A color comparator consisting of beryllium color chart was designed to enable the semi-quantitative determination of beryllium in surface samples. The system provides a minimum detection limit of 0.01 microg sample(-1). Metals tested for any interference effect include Al(3+), Ba(2+), Cd(2+), Cu(2+), Co(2+), Cr(3+), Cr(6+), Fe(3+), Hg(2+), Mg(2+), Ni(2+), Pb(2+), Ti(4+) and UO(2)(2+). Validation of the system showed no significant effect from metal interferences on the quantification of beryllium.
