The CXC core provides research support focused on passive sampling resources, including study design, hardware, chemical analysis, and data interpretation.  

The core can provide expertise in sampling of multiple environmental compartments including sediment pore water, surface water, soil pore air, and air as well as personal samplers. Each compartment requires different and specific hardware which the core can provide. 

Multiple sampler types are available. Personal samplers are focused on silicone samplers, most commonly wristbands but also available as pet tags or military-style dog tags. Environmental low-density polyethylene (LDPE) samplers are most often used for air, water, and pore-air and pore-water sampling. Each sampler type has distinct unique characteristics that define which samplers are most appropriate for a particular research question. Study design considerations are critical such that the descendent data is complete and answers the research question. 

Analytical methods are available for a variety of chemical classes. These classes are: 

  • Polycyclic aromatic hydrocarbons (PAHs) – 62 chemicals
  • Polychlorinated biphenyls (PCBs) – 43 chemicals
  • Oxygenated polycyclic aromatic hydrocarbons, (OPAHs) – 20 chemicals
  • Pesticides – 75 chemicals
  • Phthalates and phthalate replacements – 31 chemicals
  • Flame retardants – 43 chemicals
  • PAH-Forensic focused – 21 Alkylation groups
  • Hopanes and Cholestanes – 11 chemicals
  • Volatile and semi-volatile organic compounds (VOCs and SVOCs) – 108 chemicals
  • Screening method for environmental contaminants – 1,530 chemicals 

Each chemical class has an optimized method that has been developed by the core. 

Cost will be dependent on project complexity and number of samples. Additional chemistry services may be available on a per-case basis but require approval by the core director.
