USGS conducts research on asbestos
minerals through its Earth Materials and Human Health Project in Denver,
Colorado. Deleterious forms of asbestos
can occur at minor to trace (non-commercial) levels in many geologic
environments. There is growing concern that dusts containing trace asbestiform
minerals that are liberated from these geologic materials by natural weathering
or human activities may also pose a significant health hazard. In spite of
decades of research, many aspects of asbestos and fibrous minerals are poorly
understood, including: the processes by which mineral fibers trigger cancer;
whether non-asbestiform but needle-like minerals also cause cancer; the
distribution and natural background level of asbestiform minerals in dusts from various
geologic environments; how mineralogical and geochemical properties of asbestos minerals influence health effects;
and how recent earth science technologies can be applied to understand asbestos health issues. In collaboration
with human health experts, the USGS Earth Materials and Human Health Project
will develop and apply a variety of earth science methods to interpret the
geologic links between mineral dusts and human health problems. The project’s
scientific results will provide a sound earth science basis for more informed,
effective regulatory policies and remediation strategies.
