Spatial Distribution of Elemental Concentrations in Street Dust of Hanoi, Vietnam [PDF]
Bulletin of Environmental Contamination and Toxicology, 2016 Street dust samples were collected at 163 locations across four different zones of Hanoi, Vietnam, covering different traffic and population densities. Samples were sieved into three fractions of different particle sizes and analyzed for elemental concentrations (K, Ca, Mn, Fe, Zn, Pb) using an X-ray fluorescence (XRF) instrument.
