• Description:
  Exposure to particulate matter (PM) air pollution is the fifth leading cause of premature disease and death on the planet and the number one environmental risk factor for the global burden of disease (posing a greater danger than all other environmental risk factors combined) according to the World Health Organization. Despite the growing need (and demand), the state-of-the-art for assessing personal exposure to PM is based on decades-old technology that is inefficient, burdensome, and expensive. For personal monitoring, active air sampling technology typically consists of a battery-powered diaphragm pump connected by tubing to a separate size-selective inlet (e.g., a cyclone or impactor) to measure inhalable, respirable, or PM2.5 size fractions within the wearer's breathing zone. Such personal sampling equipment is expensive (typically >$1500 each), relatively heavy (>550g in total), noisy (emitting >50 dB from the pump along with substantial mechanical vibration felt by the subject), and bulky (in size and via tubing connections). The physical burden posed by these monitors (weight, bulk, noise, visual aesthetic) make them burdensome to wear. Importantly, the cost of these monitors also prevents air pollution exposure monitoring at scales relevant to epidemiologic research and occupational hazard surveillance. Further, diaphragm pumps involve a failure-prone and inefficient check valve, and the cumbersome tubing often pinches or disconnects if the wearer is physically active. There is a clear need for improved PM monitoring technologies both in the U.S. and abroad. In Phase I of this project we designed, developed, and tested a novel, lightweight, and inexpensive personal sampler based on ultrasonic piezoelectric pumping modules (a.k.a. 'micropump'). A Phase II proposal for continuation of this project was submitted in September of 2017. Three Phase II specific aims were proposed: (1) Integrate a novel, real-time PM sensor into the UPAS hardware/firmware; (2) Develop a suite of different plug-and-play size-selective inlets to make the UPAS more versatile and optimize the UPAS for weight, power, performance, and usability; (3) Validate performance of the prototype through laboratory and field testing.
