Is There Formaldehyde in New Cars?

[PeytonLee]

Newly purchased cars may contain formaldehyde. It is recommended to frequently ventilate the car and use activated charcoal to absorb formaldehyde. Avoid covering odors with perfumes. After a new car leaves the factory, the volatilization of harmful gases inside can last for more than 6 months. The volatilization period of major pollutants such as formaldehyde and benzene can even extend from 3 to 15 years. Methods to determine if it's a new car are as follows: 1. Check the manufacturing date: The manufacturing date on the vehicle should match the one on the certificate of conformity, which is usually hard to alter. If the manufacturing date exceeds 15 days, it is considered an old car. 2. Inspect the brake discs: Most small passenger vehicles nowadays use disc brakes (at least the front brakes are disc brakes), making the brake discs a reliable indicator. Generally, after driving more than 200 kilometers, the brake pads will leave noticeable marks on the brake discs. There is usually a 1-2 mm gap between the brake pads and the outer edge of the brake disc. After driving a certain distance, a so-called 'step' will form on the outer edge of the brake disc (the 'step' is very low on new cars).
