Short summary

The study reports the transition in the atmospheric emission of particles and gases from on-road heavy-duty trucks (HDTs) caused by the modernisation of the fleet. We measured particle number (PN), particle mass (PM), black carbon (BC), nitrogen oxides (NO_x), carbon monoxide (CO), hydrocarbon (HC), particle size distributions, and volatility in the plumes of 556 individual HDTs. Significant but different changes in emissions were evident for various pollutants with respect to emission standards.
