WebIn humans, phosphorus makes up about 1 to 1.4% of fat-free mass. Of this amount, 85% is in bones and teeth, and the other 15% is distributed throughout the blood and soft tissues [ 1 ]. Many different types of foods contain phosphorus, mainly in the form of phosphates and phosphate esters [ 1 ]. WebToxic industrial chemicals (whether as a gas, aerosol, or liquid) enter the body through inhalation, through the skin, or through digestion. The time that it takes for a toxic industrial chemical to begin working is dependent mainly on the route that the agent enters the body.
