CLM-PARKING-001 · VERIFIED
In a large residential underground parking garage in Tianjin, volatile organic compounds averaged 362.7 μg/m³ against 63.2 μg/m³ outdoors and were positively correlated with traffic flow, especially in the daytime; tailpipe exhaust accounted for 43.2% and evaporative emissions of fuel vapour for 33.7% of them, and evaporation from the many parked cars for 69.3% at night.
One garage in China, with sources apportioned by a statistical model; it measures air composition, not odour.
The statement the claim rests on was found word for word in the abstract fetched from the named service, and an editor read the full abstract against every part of the claim. Abstract from Europe PMC (ebi.ac.uk/europepmc).
