Presents the use of salivary leukocytes as a non-invasive biomatrix for assessing DNA damage and repair in biomonitoring studies using the comet assay, including methodological optimization and validation of both fresh and cryopreserved samples.

Introduces the principles and applications of Non-Targeted Screening (NTS) using LC-HRMS, with emphasis on broader chemical characterisation, harmonised workflows, and methodological developments in the field.

An educational resource offering scientific insights and practical examples on human biomonitoring to support chemical risk assessment and public health decision-making.

This presentation focuses on exhaled breath condensate (EBC) as a biological matrix for chromium biomonitoring, explaining its production, potential applications, and the procedures for sample collection. It outlines the method developed by the Health & Safety Laboratory in the UK for chromium speciation in EBC, supported by findings from a feasibility study.
