Formaldehyde is a colorless gas with a strong odor, commonly used in various industries. It is primarily produced for making resins, which are used in products like plywood, particleboard, and some types of furniture. Additionally, formaldehyde is found in some household products, such as disinfectants and preservatives. In nature, formaldehyde is produced in small amounts during the breakdown of organic matter. It is also a byproduct of combustion processes, such as those from vehicles and industrial activities. Due to its potential health effects, exposure to formaldehyde is regulated in many countries to ensure safety in workplaces and homes.
