Cardno ChemRisk Publishes State of the Science Review regarding Anthophyllite Asbestos

Scientists at Cardno ChemRisk recently published a study titled “Anthophyllite asbestos: state of the science review” in the Journal of Applied Toxicology. The purpose of this research was to provide a comprehensive review of the toxicological, epidemiological, and regulatory knowledge regarding anthophyllite and to understand how it compares to other types of asbestos. It also serves to give an overview of the available published literature on anthophyllite, including the occurrence of anthophyllite in talc and related health effects.

The authors reviewed publicly available documents on anthophyllite discussing its use, mining, properties, toxicity, exposure, and any potential health hazards. Based on their research, the authors found that:

· Anthophyllite has been less researched than other asbestos types.

·  Anthophyllite can be found as a trace element or contaminant of other asbestos or talc deposits.

·  In studies from the 1970s and onward, it was reported that significant anthophyllite exposure in animal studies can cause asbestosis, lung cancer, and mesothelioma.

·  A study of Finnish Anthophyllite miners in the 1970s found exposure to anthophyllite caused asbestosis and lung cancer, but not mesothelioma, which was not linked with human exposure to anthophyllite until the mid-1990s.

· Because of the lack of research on anthophyllite specifically, characterizing the health risks associated with exposure is difficult.

Overall, the authors concluded that anthophyllite may be more potent than other types of asbestos in causing asbestosis, but less potent in causing mesothelioma. However, further research is needed to fully understand the toxicity of pure anthophyllite.
