Web4 jul. 2007 · Many toxic substances including heavy metals, ozone, carbon monoxide, carbon dioxide, and nitrogen oxides are generated during welding. Ozone (O3) is a strong oxidant that generates reactive oxygen species (ROS) in tissue, and ambient ROS exposure associated with particles has been determined to cause DNA damage. Ozone is … Web3 okt. 2024 · Oct. Ozone is formed naturally by the ultraviolet rays of the sun, (photochemical reaction) and lightning (bioelectric reaction). Due to the fact that ozone in a relatively short time, turns back into oxygen, ozone can not be stored and shipped in a container or bottle. Instead, the ozone may be produced on-site by an ozone generator.
