Formaldehyde, benzene, toluene, xylene, acetaldehyde, and phthalates are the primary components. Vehicle interior temperatures reach 60-80C in sunlight — dramatically accelerating off-gassing. Ecology Center (HealthyStuff.org) tests vehicle interior chemical exposure. Off-gassing peaks in first 6 months and continues at lower levels for 2-3 years.
