主　　题：interior material formaldehyde volatile organic compounds(VOCs) multi-source emission vehicle cabin source control 

摘      要：Air pollution in vehicle cabin environment has gained increasing concern *** study addresses the necessity to predict and regulate the emissions of volatile organic compounds(VOCs)from interior materials to improve in-cabin air *** focus on how the selection of interior materials influences formaldehyde concentration levels under multi-source emission *** experiments were conducted to determine the three key parameters of formaldehyde emissions from five typical interior materials(carpet,car door,sealing strip,and two adhesives)using the C-history *** applying a multi-source emission model with the measured key parameters,various cabin emission scenarios are predicted and *** of formaldehyde concentration levels between experimental data and simulated results demonstrates the effectiveness of the *** based on the model indicates that adhesives contribute significantly to in-cabin air pollution,and the impact of different key parameters on the emission behaviors is *** with higher ratio of initial emittable concentration to partition coefficient will prolong the emission period and increase the health *** ventilation requirements for different multi-source emission scenarios are also *** results underscore the critical role of material selection in controlling formaldehyde emissions and the necessity of developing low-emitting materials to improve air quality and occupant safety in vehicle cabins.
