Therefore, the potential release of ultrafine particles (UFPs) and carbon nanotubes (CNTs) was investigated to demonstrate an appropriate aerosol measurement strategy for occupational health monitoring. UFP size distributions were characterized during the shredding (<1 mm) and milling (<0.5mm) operations using an optical particle sizer (OPS) and a scanning mobility particle sizer (SMPS). Concurrently, a Raman spectroscopy-based method enabled to selectively quantify airborne CNT mass and differentiate between multi and single wall forms (MWCNTs/SWCNTs). Method validation demonstrated consistent sampler performance with limits of quantification of 0.013 ng for SWCNTs and 0.27 ng for MWCNTs. The high chemical specificity of the Raman spectroscopy, enabling clear distinction between different carbon allotropes and resulting in minimal quantification bias, even in the presence of complex carbonaceous matrices. Overall, the proposed tried approach is robust, selective and valid for the monitoring of nanomaterial exposure in battery manufacturing and recycling environments.
