Numerous analytical methods are available for analyzing beryllium: inductively coupled plasma-mass spectrometry (ICP-MS), optical emission spectrometry (ICP-OES), atomic absorption spectrometry (AAS), colorimetric, and fluorimetric methods (10, 11). A detailed listing of the colorimetric methods can be found in Taylor et al. (12). The preferred method for soil and water analysis in the environmental business is ICP-MS following United States Environmental Protection Agency (USEPA) methods 200.7 and 6010. The ICP-MS instrumentation has greater sensitivity and reduced interference from other metals, compared to other analytical methods. A typical reporting limit of beryllium in environmental investigations using the ICP-MS method is 5 ppb; typical method of detection limits for soil and water are 0.1 µg/kg and 0.7 µg/L, respectively. AAS is also an USEPA approved process following method 7090 or 7091. Due to beryllium's low concentration and subsequent interference with other metals in environmental samples, a number of separation and preconcentration methods have been developed using chelating agents, ion-exchange resins, sorbants, and surfactants.
