Fine particles from aircraft exhaust become more harmful over time, lab tests suggest

Fine particulate matter consists of tiny particles with diameters in the nanometer range. They are produced, for example, by fuel combustion, remain suspended in the air and can penetrate deep into the respiratory tract. There, they can trigger oxidative stress, a process that pr This story matters for Science & Discovery readers tracking insect. Reported by phys.org. Read the full original at the source link below.
