Exposomics & Environmental Metabolomics Services
Exposomics investigates the totality of an individual's environmental and chemical exposures throughout their life, incorporating both external sources (such as pollutants, diet, and lifestyle) and internal biological responses (e.g., oxidative stress, microbiome alterations, and metabolic changes). Environmental metabolomics complements this by applying high-resolution analytical techniques to characterize these exposures in biological fluids, tissues, and environmental samples, uncovering the molecular signatures associated with environmental impacts on health and ecosystem stability.
Why This Matters
🔹 Holistic Exposure Profiling
Enables comprehensive assessment of complex and cumulative exposure mixtures over time, supporting long-term risk evaluation and public health strategies.
🔹 Mechanistic Understanding
Helps decipher how environmental contaminants disrupt metabolic and signaling pathways in both humans and ecological models.
🔹 Biomarker Discovery
Enables the identification of exposure-specific and effect-specific biomarkers, including those linked to emerging contaminants like PFAS and microplastics.
Our Service Capabilities
âś… Chemical Exposome Profiling (Targeted & Untargeted)
Using ultrahigh-resolution mass spectrometry, we quantify trace-level xenobiotics such as PFAS, plasticizers, flame retardants, pesticides, and pharmaceuticals in a variety of matrices (biofluids, tissues, air, and water). Both targeted panels and untargeted workflows are available to capture known and unknown components within complex exposure mixtures.
✅ Exposure–Effect Metabolomic Mapping
By integrating exogenous exposure data with endogenous metabolite shifts (e.g., lipids, organic acids, amino acids), we uncover how specific environmental stressors affect internal metabolic responses, supporting toxicological and epidemiological studies.
âś… Advanced Data Analysis & Multi-Omics Integration
We offer statistical modeling for complex mixtures, mediation analysis, and cross-omics integration (genomics, proteomics, microbiomics) to support robust exposure–response interpretation and biomarker identification.
Typical Applications
Quantifying persistent organic pollutants or PFAS in clinical or population samples (e.g., blood, urine) to identify early risk indicators.
Investigating metabolic disturbances in sentinel organisms (e.g., fish, plants, earthworms) under pollutant stress.
Profiling air, water, and soil samples to assess contaminant levels and co-exposure effects for ecological risk assessment.
- Gut–Host Interaction Studies
Exploring how environmental exposures alter gut microbiota and related host metabolic functions.
