Feb 01, 2016 · Thallium is an enormously heavy metal that can bind to sulphur and lock up the potassium receptor sites, so it is no wonder that it can be so lethal. Yet this is just one heavy metal. You could probably tell the same story about all the heavy metals in one way or another and then you must deal with all the combinations.

Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They also are produced when coal, oil, gas, wood, garbage, and tobacco are burned. PAHs generated from these sources can bind to or form small particles in the air. Hightemperature cooking will form PAHs in meat and in other ...

Jan 28, 2015 · Thallium, a grayishwhite metal similar to tin in appearance, was discovered spectroscopically in 1861. Like lead, it is heavy yet soft, and can be cut easily with a knife. When exposed to air, thallium's luster quickly tarnishes to a bluegray color owing to the formation of a film of thallium oxide. Its concentration in Earth's crust is ...
