Beryllium is used extensively throughout the electronics and aviation industries, and the Department of Energy (DOE). There are increasing numbers of cases of occupational Chronic Beryllium Disease (CBD) being reported and there is currently no cure for CBD. Chelation therapy provides a possible treatment for the reduction of a beryllium body burden. Previously, the process of chelator development in treatment of metal poisoning has been empirically slow. A new paradigm uses modern chemistry techniques such as thermodynamics, quantum molecular modeling, analytical and organic chemistry, and toxicology to evaluate beryllium chelators in biological and environmental systems. A large number of possible chelators have been assessed and ranked using the techniques described, leading to selection and development of three selective and effective chelators for further study and application: sulfo-naphthoic acids, diphosphonic acids and disulfonic acids. These techniques are also applied to evaluate chelators used for lead and heavy metal poisoning.
