Preface

final document on the development of a list of soil screening numbers based on “protection of public health and safety ” as required by Health and Safety Code Section 57008 (OEHHA, 2005). The screening numbers have no regulatory authority and are published solely as reference values that may be used by citizen groups, community organizations, property owners, developers, and local government officials to determine sites that would likely need no further action if a full risk assessment were conducted. How these soil screening levels should be applied is explained i

ed by the diffusion process). In Figure 1, the as-implanted and diffused beryllium and interstitial profiles generated are shown. One can see that, compared to Example 13, a kink in the profile occurs due to this defect non-equilibrium effect. If one increases the interstitial diffusivity in the statement: interstitial gaas D.0=5e-14 D.E= 0. from 5×10 -14 to 1×10 -11 for example, the interstitials are able to diffuse back to their equilibrium levels everywhere, and normal "Example 13 type" diffusion occurs.

An official American Thoracic Society statement: diagnosis and management of beryllium sensitivity and chronic beryllium disease

Rationale: Beryllium continues to have a wide range of industrial applications. Exposure to beryllium can lead to sensitization (BeS) and chronic beryllium disease (CBD). Objectives: The purpose of this statement is to increase awareness and knowledge about beryllium exposure, BeS, and CBD. Methods: Evidence was identified by a search of MEDLINE. The committee then summarized the evidence, drew conclusions, and described their approach to diagnosis and management. Main Results: The beryllium lymphocyte proliferation test is the cornerstone of both medical surveillance and the diagnosis of BeS and CBD. A confirmed abnormal beryllium lymphocyte proliferation test without evidence of lung disease is diagnostic of BeS. BeS with evidence of a granulomatous inflammatory response in the lung is diagnostic of CBD. The determinants of progression from BeS to CBD are uncertain, but higher exposures and the presence of a genetic variant in the HLA-DP β chain appear to increase the risk. Periodic evaluation of affected individuals can detect disease progression (from BeS to CBD, or from mild CBD to more severe CBD). Corticosteroid therapy is typically administered when a patient with CBD exhibits evidence of significant lung function abnormality or decline. Conclusions: Medical surveillance in workplaces that use beryllium-containing materials can identify individuals with BeS and at-risk groups of workers, which can help prioritize efforts to reduce inhalational and dermal exposures.
