Which structure traps pollutants at street level?
Answer: D
Flow across a street canyon separates at the upwind roof and sets up a recirculating vortex within the canyon, so pollutants emitted at street level accumulate on the leeward side. Concentrations can differ by a factor of several between the two sides of the same street. This is why roadside monitoring station siting requires such care.
