Small aerosol droplets could penetrate PPE, scientists warn

The study, published in the journal Physics of Fluids today, found that both large and small droplets travelled further than medium-sized ones.

Small aerosol droplets could penetrate some personal protective equipment (PPE) used to shield people from infections like coronavirus, scientists have warned.

A team of researchers from Scotland's Heriot-Watt University and the University of Edinburgh created a mathematical model that separated how small, medium and large aerosol droplets were dispersed through the air.
