Interesting Thallium Facts: Thallium was discovered by two scientists independently of each other, William Crookes and Claude-Auguste Lamy, in 1861. It was found as a byproduct of sulfuric acid manufacturing. Both scientists discovered it by using the then-newly created flame spectroscopy method. For several years after its discovery, thallium ...

Male mice were exposed to thallium carbonate in drinking water for six months. The results of sperm analysis indicated that thallium carbonate level of 0.01 mg/l had an adverse efffect on the spermatozoa of mice by lowering their fertility, while a concentration of 0.001 mg thallium carbonate/l can decrease sperm motility in treated mice.
Thallium is present in mainly industrial wastewaters. Information on specific waste streams is not difficult to find; however, individual mines often do not want their thallium concentrations published (MWTP, 1999).Cheam et al.

How to detox thallium. Thallium is a toxic metal that causes serious fatigue. It bioaccumulates, meaning, it builds up in the body over time, and causes serious health conditions. It is added to gasoline and released into the air by car exhaust. For this reason, thallium toxicity is almost always prevalent in those who live in urban environments. …

It can be cut with a knife. Twenty five isotopic forms of thallium, with atomic masses ranging from 184 to 210 are recognized. Natural thallium is a mixture of two isotopes. A mercury-thallium alloy, which forms a eutectic at 8.5% thallium, is reported to freeze at -60C, some 20 degrees below the freezing point of mercury. Handling
Thallium is a heavy, bluish-white metal that resembles lead, element 82. Thallium is very soft and melts easily.
