Lead in the air is regulated two ways under the Clean Air Act: As one of six common pollutants for which EPA has issued national ambient air quality standards (NAAQS), and; As a toxic air pollutant (also called a hazardous air pollutant) for which industrial facility emissions are regulated.; Under the lead NAAQS, EPA limits how much lead there can . Sulfur is non-toxic. However, burning of sulfur can lead to production of sulfur dioxide gas, which at high concentration can lead to damaging effects on eyes, lungs and other tissues. Similarly, other compounds of sulfur, including sulfuric acid is highly corrosive acid and its fumes are damaging to the eyes and nasal linings. Aug 09,  · Well, this is the common uses for oxygen the element. Humans cannot live without oxygen because they need it to burn the fuel inside their body in exchange for energy. Nobel laureate Otto Heinrich Warburg has proven in that the lack of oxygen in cells could lead into cancer. His breakthrough inspires other scientists to find the cure.
