What Are Some Common Spectroscopic Techniques Used in Toxicology?
Several spectroscopic techniques are widely used in toxicology:
- UV-Visible Spectroscopy: This method is utilized to study the electronic transitions of molecules. It is particularly useful in analyzing the presence of chromophores in toxicants.
- Infrared (IR) Spectroscopy: IR spectroscopy is employed to determine the functional groups present in toxic molecules. It provides a molecular fingerprint useful for identifying unknown substances.
- Nuclear Magnetic Resonance (NMR) Spectroscopy: NMR spectroscopy offers detailed information on the molecular structure and dynamics of toxic compounds. It is valuable for understanding how toxicants interact with biological molecules.
- Mass Spectrometry (MS): Often coupled with chromatographic techniques, MS provides information on the molecular weight and structural features of toxins, facilitating their identification and quantification.
- Atomic Absorption Spectroscopy (AAS): This technique is used to measure the concentration of metal ions in samples, which is crucial for assessing metal toxicity.
