Outgassing, where atoms, ions, or molecules have adsorbed to the surface of the product and are now re-entering the air around the product. The reason “New Car Smell” doesn’t smell like anything else in nature is because it is not natural. It is most likely the result of a combination of extremely harsh chemicals from epoxies, lubricants, solvents, and paints. These combinations of chemicals can be dangerous to humans and also to complex equipment like spacecraft. Luckily, a team of NASA engineers have developed a new way of neutralizing these gases and protecting us from the effects of outgassing.
