Bulk samples


The chemical composition of the bulk materials and substances is a key activity for the risk assessment. The risks are determined not only by the process, but also for materials composition. The analysis of the bulk sample provides this information.


In the lab of the National Institute for Silicosis, the following analysis are undertaken on bulk samples:


  • Respirable crystalline silica (RCS). Before of materials processing RCS in bulk samples must be evaluated, especially taking into account the carcinogenic nature of the agent. The correct labeling of the product is an essential requirement for its commercialization and use as an intermediate or final product.


  • Crystalline phases. The correct characterization of a material requires not only the identification of its components but also the quantification of its crystalline phases.


  • Metals. The presence of metallic hazardous substances in mineral products, used increasingly in a greater number of applications, is of great importance for the industries that manufacture and trade with them.


  • PAHs. The identification and quantification of aromatic polycyclic hydrocarbons in bulk samples is very important in order to evaluate the risks linked to the handling and trading, of carcinogenic products.


  • Granulometric analysis. The particles characterization is a perfect complement for the risk assesment of the bulk material. Health risks of the products are not only influenced by their composition but also by the size of their particles.
