This study demonstrated that using lead-doped keratin film as a calibration standard allows for accurate tracking of lead distribution along hair strands, revealing different exposure patterns among workers in a battery manufacturing factory in Thailand.

This study found that while measuring zinc in hair did not allow calculation of individual hair growth rates, it effectively characterized zinc, lead, and mercury concentrations and improved methods for analyzing these exposures using LA-ICP-MS.

This review discusses the growing use of scalp hair for elemental analysis in various fields and highlights advancements in analysis techniques, including the future potential of laser ablation ICP-MS, but reports no new clinical results.

This study found that laser ablation-inductively coupled plasma-mass spectrometry can effectively reconstruct time-resolved mercury exposure in micrometer segments of a single hair strand from fish-eaters.

This study found that variations in mineral content of hair, such as increased Zr in asthma and respiratory infections, may be linked to different illnesses, suggesting potential diagnostic use.
