Passive sampling devices are designed to mimic biological membranes, absorbing volatile and semi-volatile chemicals (SVOCs). These devices are called 'passive' because they do not require any maintenance or power to work. They can detect pesticides, flame retardants, nicotine, pharmaceuticals, consumer products and polycyclic aromatic hydrocarbons.
There are two different formats of these devices: the passive wristband sampler which can measure personal exposure and the stationary passive air sampler which can be set up in your environment. Learn more about these below.
Passive Wristband Sampler
The passive wristband samplers are small, lightweight wristbands that can monitor our personal exposure to air pollution by absorbing chemicals found in the air. The wristbands are available in a wide range of colors. Simply slide it on your wrist, and go about your day as usual!
Below Dr. Kim Anderson describes how the passive wristband samplers can be used.

Stationary Passive Air Sampler
The below video shows the step-by-step process of preparing the low-density polyethylene (LDPE) passive sampler device to measure air quality with field examples from the Gulf of Mexico oil spill.
