Chemical speciation, risk assessment, and pollution level of lead metals in road dust of some industry zones and urban areas in Northern Vietnam
This study analyzed the chemical speciation of Pb metal in road dust samples from six provinces in northern Vietnam. Samples were extracted according to Tesser's sequential extraction procedure and measured by the ICP/MS method, with the total recovery of Pb ranging from 90.9% to 107%.
