TL;DR: Thallium contamination in soils should be a critical parameter for proper land use and health related environmental planning and regulations in areas containing high contents of Tl in soils associated with the natural occurrence of TL-rich sulfides and coals, with or without mining activities.

TL;DR: Tl is regarded as a latent health hazard with potential risk of toxicity in humans within areas of "natural" contamination by Tl, and more attention must be paid to geoenvironmental management of human activities if socio-economic catastrophes are to be avoided.

TL;DR: In this article, a small karstic watershed of Lanmuchang, in a Hg-Tl mineralized area in SW Guizhou Province, China, exhibits an enrichment of toxic Tl in groundwater and related stream water.

TL;DR: It is demonstrated that natural sources of elevated Tl pose a potential health risk to the population, and that monitoring the urinary Tl concentration is a reliable and accurate way of bio-marking Tl exposure.

TL;DR: In this article, the changes in composition of fluid inclusions using solid-probe mass spectrometry were monitored to establish and verify systematic changes in the composition of the fluid during fluid-rock interaction, characterizing the composition and behavior of fluids in the vein and the wall rock, and elucidating new insights on the role of fluid immiscibility in gold deposition.
