Particle size distribution and elemental composition of road associated particles: Contrasting three collection techniques

articles, introduced through stormwater runoff, impact receiving waters through increased turbidity and constituent loads; particle size is paramount in a particle's fate and transport. Road associated particles were collected by vacuuming road surfaces (2 sites; n=4), centrifuging stormwater runoff (3 sites; n=7), and capturing settled detention basin solids (3 basins with 3 locations per basin; n=27). Particle size distribution (PSD) was evaluated using three methods: particle number distribution (PND) by light scattering (0.5 dp<20;...
