Lead(II) phosphate is an ionic compound with chemical formula Pb 3 (P O 4) 2. Lead(II) phosphate is a long-lived electronically neutral reagent chemical. [2] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA. [3] Lead(II) phosphate appears as hexagonal, colorless crystals or ...
Lead interferes with metabolism of bones and teeth [188] and alters the permeability of blood vessels and collagen synthesis. [5] Lead may also be harmful to the developing immune system, causing production of excessive inflammatory proteins; this mechanism may mean that lead exposure is a risk factor for asthma in children. [188]
Animal studies have shown that repeated exposure to tributylphosphate, one of the phosphate esters used in Skydrol fluids, may cause urinary bladder damage. [4] If Skydrol gets in the eyes, it creates an intense stinging sensation. The recommended treatment for this is to use an eye-wash station, sometimes mineral oil, castor oil or milk is used.
2. Baby Food. One might think that a product advertised for infants and young children would be safe to eat. Alas, it's shocking how much food marketed to kids contains lead.
Archaeologists have traced the earliest case of lead pollution by humans to the Aegean Sea region around 5,200 years ago.. The findings, published in the journal Communications Earth & Environment ...
One example of a pressure phosphene is demonstrated by gently pressing the side of one's eye and observing a colored ring of light on the opposite side, as detailed by Isaac Newton. [ 7 ] [ 8 ] [ 9 ] Another common phosphene is "seeing stars" from a sneeze , laughter, a heavy and deep cough, blowing of the nose , a blow on the head or low blood ...

Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
