This peer-reviewed proof-of-concept study demonstrates that electrothermal vaporization inductively coupled plasma optical emission spectrometry combined with multivariate analysis can accurately classify the sex of individuals from both dyed and undyed hair samples, highlighting its potential as a green, forensic tool for human sex determination.
In this digital e-book “Spectroscopy and the Environment: Analyzing Air, Water, Land, and Life,” we examine the critical role of light-based analysis in monitoring the planet's health. Focusing on the four main categories in earth science—atmosphere, hydrosphere, lithosphere, and biosphere—we explore how advanced spectroscopic techniques can serve as a vital toolkit for environmental protection. Key topics include the detection of methane and particulate matter in the air, the discovery of microplastics in remote water sources, and the use of satellite imaging for land management.
