Pulmonary arterial hypertension is a rare but severe disease with an estimated five-year survival rate of only 57% after diagnosis, according to the Registry to Evaluate Early And Long-term PAH disease management (REVEAL), which registers data from patients in the United States.
Concentration of elements in the ocean relative to the total concentration in the bulk silicate Earth (BSE). Of all the elements, only Cl and Br have a significant fraction in the ocean (see inset), indicating the extreme hydrophilic character for the heavier halogens.
Chlorine in its natural form is a common element on the Earth. When at room temperature chlorine is a yellowish-green gas. This gas is very toxic. Chlorine vaporizes much faster than water, so when we shower we are actually absorbing and inhaling up to 50% more Chlorine than if we were to just drink the water.
