About
Mark R. Fresquez is a leading researcher in analytical chemistry, specializing in the precise measurement of mercury and its toxic species in biological and environmental matrices. His major contributions center on developing advanced methodologies using triple spike isotope dilution combined with solid-phase microextraction (SPME) and gas chromatography coupled with inductively coupled plasma dynamic reaction cell mass spectrometry (GC-ICP-DRC-MS). His seminal 2014 paper, "Measurement of mercury species in human blood using triple spike isotope dilution with SPME-GC-ICP-DRC-MS," which has garnered 32 citations, established a gold standard for quantifying inorganic mercury, methylmercury, and ethylmercury in human blood with unprecedented accuracy and minimal sample preparation. This work is critical for understanding mercury exposure pathways and toxicokinetics, directly impacting public health assessments and regulatory guidelines. Fresquez’s research is notable for its rigorous validation and application to real-world biomonitoring studies, bridging the gap between complex analytical chemistry and practical human health risk evaluation. His contributions continue to influence trace metal speciation analysis, making him a key figure in environmental and clinical toxicology.
