What Do Safety Data Sheets for Artificial Stone Products Tell Us About Composition? A Comparative Analysis with...

Area of Science:

• Materials Science
• Occupational Health
• Analytical Chemistry

Background:

• Artificial stone (AS) is widely used in construction, especially for kitchen benchtops.
• AS fabrication is linked to serious occupational lung diseases.
• Safety data sheets (SDSs) are intended to inform about material composition and health risks.

Purpose of the Study:

• To compare the actual mineral, metallic, and organic resin content of AS products with information provided on supplier SDSs.
• To assess the adequacy of SDSs in communicating health risks associated with AS.

Main Methods:

• Empirical analysis of 25 AS products from six suppliers.
• X-ray diffraction (XRD) for mineralogical quantitation.
• X-ray fluorescence (XRF) for metallic component estimation.
• Calcination for organic resin content determination.

Main Results:

• Resin content generally matched SDS ranges, but crystalline silica content varied significantly compared to SDS information.
• Many SDSs failed to report potentially toxicologically relevant metallic and mineral constituents.
• Only one supplier reported crystalline minerals beyond silica, and only two reported metals.

Conclusions:

• Current SDSs for AS often lack comprehensive and standardized information on hazardous components like crystalline silica and metals.
• Inconsistent and incomplete SDS data hinders effective risk assessment and management for lung diseases linked to AS.
• There is a critical need for improved and standardized SDS content to protect worker health in AS fabrication.
