QUESTIONS ABOUT BUS INTERIOR
A bus interior smells of fabric seats, rubber flooring and warm plastic, held in recirculated, slightly stale air. Depending on the day it can add damp coats, food, perfume or the cold outside air that rushes in at each stop. The smell is mixed and muted rather than strong, heavier when the bus is crowded and warm.
It is met on city buses during the daily commute, on school and coach journeys, and on routes busy in rush hours. Many passengers notice it most on rainy days, on a crowded upper deck or a packed seat near the back, with damp coats all around.
Typical settings: city bus, commute, public transport.
SmellBook links it to one place page: see it in Connections.
One VERIFIED scientific claim from one published source is recorded for this entry: Solvent compounds in bus and metro interiors. This claim says only what its source supports, in the scope shown with it.
The scientific study behind this evidence is chemistry or emission work, not a study of how the smell is perceived.
2 molecules are named in this claim; see the evidence for the role the claim gives them. The molecules this claim names were detected or measured in the study. The claim does not say they shape the smell.
Bus Interior is an editorial transit profile and not an air-quality or cleanliness assessment.
SmellBook records one written comparison with other smells: see it in Connections.
No historical source or heritage record is linked to this entry yet.
Answers marked EDITORIAL are written by SmellBook editors to describe the experience and add no scientific fact. Answers marked VERIFIED point to claims on published sources, checked against each source's own summary where one was available (each claim's page says how); what each claim supports is in its own text and scope.

Solvent compounds in bus and metro interiors
Among nine Hong Kong public transport modes, toluene, ethylbenzene and xylene levels were substantially higher in air-conditioned buses and Mass Transit Railway trains than in the others, which the authors take to suggest additional solvent-related sources in those vehicle interiors.
Five winter months of 2001–02; it measures air composition, not odour, and the levels were within Hong Kong's health-protecting limits.
How this was found: Emissions or air measured. What a material, product or place releases into the air was measured, usually without assessing odour. Source: primary study; material-emission work.

PATHS FROM HERE
Each step is a relationship SmellBook editors recorded in the knowledge graph, named as it is published there. Paths are not ranked or personalised, and they do not mean the smells smell alike.
Each step is a molecule that a VERIFIED claim names for both smells, in whatever role the claims state. Sharing a molecule does not mean two smells smell alike.
