Emerging Contaminants are a broad category of environmental chemicals, previously unknown or unrecognized as being of concern but that are under increasing scientific scrutiny. In general, these contaminants are not regulated in the traditional sense of having allowable levels determined for specific environments. Current understanding of this category of contaminants often contains significant gaps, including their toxicity, bioaccumulation, occurrence, transport, and transformation mechanisms. Many emerging contaminants are families of chemicals over which concern has been raised for at least some of the compounds in the group.

Emerging contaminants generally have few “point sources” of release or exposure and are widely used in consumer goods, serving useful day-to-day functions within society. Human exposure and body burdens are generally of key concern for these contaminants precisely due to their broad applications. Many compounds are Persistent Bioaccumulative Toxics (PBTs), while others are associated with endocrine disruption, including estrogenic effects in humans or animals. As advances in the sensitivity of analytical methods are achieved, these compounds will continue to be studied by researchers and regulators.

AXYS Analytical Services Ltd. has been specializing in the measurement of emerging contaminants since 1978 through our work on dioxins, furans and PCB congeners. Though these PBT chemicals are now heavily regulated, AXYS continues to demonstrate leadership in the analysis of a wide variety of emerging contaminants that require measurement in the nanogram to picogram range, best measured by GC HRMS or LC/MS/MS instrumentation.

Examples of AXYS emerging contaminant analysis expertise include measurement of:

AXYS specializes in measurement of emerging contaminants at nanogram to picogram concentrations from standard sample sizes. Our specialized sampling and analytical procedures may allow for much lower detection limits and a reduction of sample size required for human and sediment matrices. We provide legally defensible measurement of these compounds in a wide variety of matrices including water, soil, sediment, air, tissue, blood and serum.

AXYS Analytical Services Ltd. is ISO 17025 certified and has a wide variety of accreditations including NELAP and CAEAL. For emerging contaminants, accreditation is not available in many jurisdictions. Benchmarking of analytical precision in emerging contaminants is generally pursued through participation in available performance evaluation and "round-robin" testing as well as participation in relevant technical forums throughout the world. We offer a wide variety of Electronic Data Deliverables (EDD) customized for download to our clients' relational databases in addition to standard format report and full data packages.

Organochlorine Legacy Compounds

Legacy compounds typically have well developed regulatory guidelines for allowable concentrations of target analytes in soils, sediment, water, and biota. The many structural forms of organochlorine compounds result in divergent chemical properties and a broad range of historical and current uses. Organochlorines are compounds with organic structures containing at least one covalently bonded chlorine atom.



Our expertise extends to a wide variety of fully commercialized tests for organochlorine legacy compounds like dioxins and PCBs, to analysis of emerging and pre-regulatory contaminants. Many of our technologies employ serial isotope dilution through the use of carbon isotope standards to enhance our detection limits, selectivity, and reduction of interferences.
