Systematic Review Protocol for the Methylmercury (MeHg) IRIS Assessment (Preliminary Assessment Materials)
The general population is predominantly exposed to methylmercury through consumption of contaminated fish and other seafood. Subsistence fishing communities and other populations with high dietary intakes of predatory fish species could be exposed to higher-than-average levels of methylmercury. Contaminated rice and rice-based food products, such as infant cereals, also can be a source of methylmercury exposure.
Methylmercury readily crosses the placenta and concentrates in cord blood. It is also transferred from mothers to children via breastmilk. The developing nervous system is particularly sensitive to methylmercury, so gestational, lactational, and other postnatal exposures are of concern.

|EPA released a draft document titled, Reference Dose for Methylmercury (NCEA-S-0930)" for a 30-day public review and comment period. Following the review an external peer-review workshop was held to review the document.
|EPA released the IRIS Summary for Methylmercury on the IRIS website and released the water quality criteria guidelines for states and authorized tribes.
|EPA released the Methylmercury Implementation Guidance.
|EPA released an update, referred to as the Methylmercury Implementation Guidance (Updated Apr 2010).
|EPA released the IRIS Assessment Plan (IAP) for Methylmercury for public comment and review. [Federal Register Notice Apr 4, 2019]
