Mercury occurs naturally in geologic materials in the environment and can exist in inorganic form as salts. In its inorganic form, mercury occurs abundantly in the environment - primarily as the minerals (e.g., cinnabar (HgS), metacinnabar) - and as impurities in other minerals. Its geologic associations are with volcanic rocks and hydrothermal systems. The abundance of each of these in the environment make it available for combining with chlorine, sulfur, and other elements as it weathers to form these and other inorganic salts. Inorganic mercury salts can be transported in water and occur in soil.
Human exposure to inorganic mercury salts can occur both in occupational and environmental settings. Occupations with higher risk of exposure to mercury and its salts include mining, electrical equipment manufacturing, and chemical and metal processing in which mercury is used. In the general population, exposure to mercuric chloride can occur through the dermal route from the use of soaps and creams or topical antiseptics and disinfectants. Exposure may also occur from consuming outdated medicinal products, such as laxatives, worming medications, and teething powders.
|Oct 2019||EPA released the IRIS Assessment Plan (IAP) for Inorganic Mercury Salts for public comment and review. [Federal Register Notice Oct 8, 2019]|
|Dec 2019||EPA hosted a public science meeting to discuss preliminary meeting materials for inorganic mercury salts.|
|Mar 2021||EPA released the Systematic Review Protocol for the Inorganic Mercury Salts IRIS Assessment (Preliminary Assessment Materials) for a 30-day public review and comment period.|
The IRIS Program will use the methods for conducting the systematic review as described in the protocol to develop the draft assessment.
