Health and ecological risk assessment of potentially toxic metals in road dust at Lalibela and Sekota towns, Ethiopia

Source and respiratory deposition of trace elements in PM2.5 at an urban location in Dhaka city

“…Si, Al, Fe, K, Ti, and Ca are crustal tracer elements since they are part of the elements that make up the Earth's crust [ 41 ]. A complex mixture of organic and inorganic substances that are transported, deposited, and then resuspended makes up road/soil dust [ 42 ]. According to Begum & Hopke, soil dust has seasonal variation and contributes significantly more in the winter [ 25 ].…”

“…The street dust in such cities is contaminated by arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) beyond the median levels of the world soil background values [ 71 ]. The United States America (USA) Environmental Protection Agency’s health risk evaluation model showed that the total heavy metal health risk levels in the road dust ranged from 5.71 × 10 -3 (adult) to 2.57 × 10 -2 (children), with an average risk of 7.35 × 10 -2 [ 72 ]. Heavy mercury (Hg) air pollution has been reported in the vicinity of compact fluorescent lamp (CFL) plants and Hg mining areas [ 73 , 74 ].…”
