Research published in Physics of Fluids shows that not all standing positions in airport smoking lounges are created equal. Scientists from the University of Hormozgan in Iran found that the thermal environment and positioning of smokers influences how particles settle in the room. Additionally, smokers seated farther from ventilation inlets experience the lowest levels of pollution in the room.
