TL;DR: In this article, a scheme for the speciation of metals in freshwaters has been applied to the metals Pb, Cd, Cu, Fe and Mn in the treated effluent of a lead-acid battery manufacturer and the receiving river upstream and downstream of the effluent outfall.

TL;DR: In this article, the authors used TEOM (gravimetric equivalent) to measure the contribution of non-traffic sources of PM10, PM2.5 and PM2, and found that the annual average traffic contribution to the urban increment is estimated as 1.6-4.4

TL;DR: It is concluded that the nature and origins of the AMS COA factor measured at a rural site are complex and include far more than the emissions from food cooking.

TL;DR: In this paper, a cluster analysis of particle size distributions (PSDs; size range ≥ 8-500 nm) was performed at three high Arctic sites during a 3-year period (2013-2015).

TL;DR: In this paper, a comparison of road traffic source profiles derived from US dynamometer studies of individual vehicles with a traffic profile derived from measurements in a road tunnel in France and new data derived from a twin-site study in London in which concentrations at an urban background site are subtracted from those measured at a busy roadside to derive a traffic increment profile.
