Analytical microscopy was used to study the distribution and chemical composition of thorium deposits in bone marrow and liver after injection of thorium dioxide and thorium nitrate. Thorotrast (thorium dioxide) was identified as being localized in bone marow macrophages of a patient who had undergone cerebral arteriography forty two years ago.Large thorotrast deposits were also present in ...
Thorium is a naturally occurring, radioactive substance. In the environment, thorium exists in combination with other minerals, such as silica. Small amounts of thorium are present in all rocks, soil, water, plants, and animals.Soil contains an average of about 6 parts of thorium per million parts of soil (6 ppm). More than 99% of natural thorium exists in the form of thorium-232.
Used as a Portland cement additive, for agricultural soil amendments, mine reclamation, melting river ice and as subsurface material for roads, coal fly ash also is a concentrated repository for many trace elements: arsenic, barium, beryllium, boron, cadmium, chromium, cobalt, lead, manganese, mercury, molybdenum, selenium, thallium, thorium ...

Why the EPA would permit the indiscriminate, systematic and wide-area spraying of coal-fly-ash based aerosols containing arsenic, lead, mercury, thallium, thorium and uranium is anyone's guess. Such a practice is in direct violation of so many EPA rules and regulations that it certainly defies explanation.

Mar 01, 2013· Thallium concentrations of up to 46 μg g −1 (ash basis) have been detected in high-As, high-S lithotypes in the Pond Creek coal bed in Pike and Martin counties, eastern Kentucky . The high concentrations could be attributable to Tl–As substitution in pyrite, which is supported by the correlation of Tl and As with pyritic sulphur.
